Description

ARTICULATED SYSTEMS FOR CARDIAC ABLATION
Field of the invention
The invention generally relates to cardiac ablation catheters and systems. In a more specific sense, the invention relates to catheters that use microwave energy to ablate ventricular and atrial tachycardia foci for the treatment and control of car¬ diac arrhythmias. Background of the Invention
Physicians make use of catheters today in medical procedures to gain access into interior regions of the body to ablate tissue areas. It is important for the physician to be able to accurately steer the catheter to the ablation site. Once at the site, it is important for the physician to control the emission of energy within the body used to ablate the tissue.
The need for accurate steering and precise control over the catheter is especially critical dur¬ ing procedures that ablate tissue within the heart. These procedures, called electrophysiology therapy. are becoming increasingly more widespread for treating cardiac rhythm disturbances, called arrhythmias.
During these procedures, a physician steers a catheter through a main vein or artery (which is typically the femoral artery) into the interior region of the heart that is to be treated. The physician then further manipulates a steering mechanism to place the electrode carried on the distal tip of the cathe¬ ter into direct contact with the tissue that is to be ablated. The physician directs radio frequency (RF) energy from the electrode tip through the tissue to an indifferent electrode to ablate the tissue and form a lesion.
Some clinicians have suggested the use of microwave energy for cardiac ablation. For example, Langberg U.S» Patent 4,945,915 proposes the use of a helical microwave antenna fed by a coaxial line to thermally ablate cardiac tissue. The radiation heat¬ ing patterns that microwave energy propagate can, in theory at least, form lesions that are deeper than the lesions formed by the conductive heating patterns gen¬ erated by conventional RF energy.
The ability of microwave energy to form deeper lesions also raises challenges in antenna sys- tern design. To gain all the benefits of using micro¬ wave energy, the clinician must be able to control the distribution of heating patterns propagated at the intended lesion site.
A microwave antenna generates an electromag- netic field that radiates in a radial plane, perpen¬ dicular to the axis of the antenna. The radial field has only minimal intensity forward of the tip of the antenna.
The radial field orientation of a microwave antenna is not well suited for use in conventional cardiac ablation procedures. In cardiac ablation us¬ ing RF, the physician is accustomed to placing the ablation electrode tip down upon the ablation site, i.e., perpendicular to the site. Orienting a micro- wave antenna in this manner directs only a small per¬ centage of the energy field upon the ablation site. Most of the energy radiates into the blood pool and serves no useful purpose. The benefits of microwave energy ablation are lost. Ablation systems and processes using micro¬ wave energy will not find widespread clinical use, if they cannot be made and controlled to direct the major portion of the radial electromagnetic field upon the ablation site. They will also fail to find widespread use, if the microwave antenna cannot be conveniently steered and positioned to the proper orientation at desired ablation site. Summary of the Invention
One aspect of the invention provides an im- proved assembly for steering and orienting a function¬ al element at the distal end of a catheter tube. The functional element can be an active electrode or an¬ tenna for ablating tissue using RF, laser, and the like. The functional element can also be a passive monitoring element, like one or more mapping elec¬ trodes, MAP elements, or ultrasound electrodes.
A mechanism supports the functional element at the distal end of the catheter tube. The mechanism holds the functional element with its major axis aligned with the axis of the catheter tube for conve¬ nient steering to a tissue site. The mechanism can also pivot the functional element in response to an external force to orient the major axis of the func¬ tional element generally parallel to the plane of the tissue site, without bending the catheter tube. In one embodiment, the pivot mechanism in¬ cludes a ball and socket joint.
In a preferred embodiment, steering wires are connected to the pivot mechanism and to a remote actuator mechanism that is accessible to the user for applying the external force.
In one embodiment, the pivot mechanism is restricted to a predefined field of movement. It can also including detents for releasable retaining the pivot mechanism in one or more preselected positions.
The pivot mechanism that embodies the fea¬ tures of the invention is ideally suited for use in association with a microwave ablation antenna. The pivot mechanism allows the user to lay the major axis of the antenna parallel to the ablation site. In this orientation, the ablation site is exposed to the full radial field propagated by the antenna.
The pivot mechanism that embodies the fea¬ tures of the invention is also ideally suit for use with antenna and the like that are unidirectional. The pivot mechanism can restrict the movement of the unidirectional element to assure its proper orienta¬ tion with the tissue site.

Fig. 1 shows an articulated antenna assembly 10 that embodies the features of the invention. The antenna assembly 10 is located at the distal end of a catheter 12. The catheter 12 includes a handle 14 (shown diagrammatically in Fig. 9) and a guide body 16. The guide body 16 is flexible with its proximal end at¬ tached to the handle 14. The antenna assembly 10 is attached to the distal end of the guide body 16. In use, the catheter provides electrophysi- ology therapy in the interior regions of the heart.
When used for this purpose, a physician grips the handle 14 and maneuvers the guide body 12 through a main vein or artery (which is typically the femoral arterial) into the interior region of the heart that is to be treated. The physician then fur¬ ther steers the antenna assembly 10 to place it in contact with the tissue that is to be ablated. The physician directs energy to the antenna assembly 10 to ablate the tissue contacted.
In the illustrated embodiment shown in Figs. 1 to 9, the antenna assembly includes a helical micro¬ wave antenna 18 (best shown in Figs. 5 and 6) . The antenna 18 is encapsulated in a potting compound 20. Preferably, the potting compound 20 includes a materi¬ al (like diamond or sapphire) that has the combined characteristics of (i) a high dielectric constant; (ii) low microwave energy loss; and (iii) high thermal conductivity. The compound 20 provides a high dielec- trie constant for the antenna 18. By minimizing the loss of microwave energy by the antenna 18, the com¬ pound 20 also maximizes the propagation of the desired radiation heating patterns about the antenna 18. The compound 20 has high thermal conductivity that dissi- pates any undesirable conductive heat patterns about the antenna 18.
Further details of the compound 20 are found in copending patent application entitled "Steerable Microwave Antenna Systems For Cardiac Ablation that Minimize Tissue Damage and Blood Coagulation Due to Conductive Heating Patterns," which shares the same filing date and assignee as this application.
The microwave antenna 18 propagates an elec- tromagnetic field 22 that radiates in a plane perpen- dicular to the major axis 24 of the antenna 18 (as
Fig. 2 diagrammatically shows in phantom lines) .
There is very little field propagation forward of the distal tip of the antenna 18.
According to one aspect of the invention, the antenna assembly 10 includes means 26 for pivoting the antenna 18 relative to the end of the guide body 12 without bending the guide body 12. The pivot means 26 orients the antenna 18 so that its major axis 24 lays generally parallel to the surface of the tissue 28 to be ablated. This orientation exposes the tissue 28 to the maximum intensity of the radial field 22 the antenna 18 propagates.
The pivot means 26 can be variously con¬ structed. In the illustrated embodiment, the pivot means 26 takes the form of an articulated jointed as¬ sembly attached to the distal end of the guide body 12. The jointed assembly 26 includes a socket housing 30 and a ball 32 pivotally carried within the socket 30. The antenna assembly 10 includes a coaxial cable 34 that extends within the guide body 12, into the socket housing 30, and through a passage 36 within" the ball 32 for attachment to the antenna 18. The coaxial cable 34 has three, functionally different regions 38, 40, and 42.
The first region 38 constitutes the majority of the coaxial cable. It is enclosed within an outer insulation sheath 44 and runs along the guide body 16.
In a preferred embodiment, the sheath 44 has an outer diameter of about .06 inch.
In the second region 40, the outer sheath 44 is absent, leaving a metallic mesh shield 46 that sur¬ rounds the core conductor wire 48. In an preferred embodiment, the mesh shield 46 has an outer diameter of about .054 inch. The second region 40 extends into the socket housing 30 and within the ball passage 36. With the removal of the relatively bulky outer sheath 44, the second region 40 is significantly more, flexi¬ ble than the first region 38 and accommodates movement of the ball 32 within the socket housing 30 (as Fig. 6 shows) .
The third region 42 is at the distal end of the cable 34. It passes from the ball passage 36 and joins the helical antenna 18. There is no surrounding sheath 44 or shield 46 in the third region 42, leaving the core conductor 48 of the cable 34 exposed.
In a preferred embodiment, the core conduc¬ tor 48 is silver coated copper having an outer diame¬ ter of about .018 inch. With the antenna 18, the third region 42 is encapsulated within the compound 20.
A shaft 50 joins the compound-encapsulated antenna 18 to the ball 32 for unified pivotal movement in a continuous multidirectional field. The user can pivot the compound-encapsulated antenna 18 by placing its distal tip 52 against the ablation site and applying a lateral force upon the catheter guide body 12 (see Fig. 1) . With the tip 52 against the tissue, the lateral force will cause the compound-encapsulated antenna 18 to pivot and lay flat against the tissue 28 at the ablation site, without otherwise bending the guide body 12.
As shown in Figs. 1 to 3, the jointed assem¬ bly 26 accommodates pivotal movement in any plane. When pivoted, the compound encapsulated antenna 18 will lay either as shown in Fig. 2 or as shown in Fig. 3, depending upon the topography of the adjacent tis¬ sue 28.
In a preferred arrangement, the jointed as- sembly 26 also includes a steering mechanism 54 for pivoting the ball 32 without the need to apply lateral force on the guide body 12.
The steering mechanism 54 can be variously constructed. In the illustrated embodiment, the steering mechanism 54 includes four steering wires 56 that are attached to the ball shaft 50 at 90 degree intervals. The steering wires 56 are retained in re¬ cessed grooves 58 in the ball 32.
As Figs. 7 to 9 shown, the steering wires 56 extend from the shaft 50, through the grooves 58 and the guide body 12 to join a remote steering lever 60 on the catheter handle 14.
In this arrangement, the user can move the steering lever 60 up, down, left, and right and pivot the ball 32 to move of the compound-encapsulated an¬ tenna 18 in the same direction. As before, this piv¬ otal movement occurs without bending the catheter guide body 12.
Fig. 10 shows another embodiment of the jointed assembly 26. In this embodiment, the ball 32 includes detents 62 formed at preselected pivot posi¬ tions. The socket housing 30 includes bearings 64 that are biased by washers 66 to nest within the detents 62. The nesting between the bearings 64 and the detents 62 retains the ball 32 in a series of pre¬ defined pivot positions. Additional pivot force upon the ball 32 releases the nested bearings 64 and detents 62. In this way, the user can pivot the com¬ pound-encapsulated antenna 18 within a range of prese- lected positions.
Fig. 11 shows another embodiment of a steer- able antenna assembly 10" that embodies the features of the invention. The assembly in Fig. 11 includes a unidirectional microwave antenna 18» . The unidirectional antenna 18' comprises a sandwich of three layers that are encapsulated in the compound 20. The first layer 68 comprises the core conductor 48 of the coaxial cable 34 (i.e., its third region 42) . The second layer 70 is a dielectric mate- rial, called the dielectric plane. The third layer 72 is an energy conducting ground plane.
As Figs. 11 and 12 show, the antenna 18• propagates an electromagnetic field 22' that radiates in a single direction from the major axis 24 of the core conductor 48. There will be little, if any, field emission radially from the ground plane 72, as well as forward of the tip 52 of the antenna 18' .
Preferable, the antenna assembly 10* also includes a unidirectional pivot mechanism 74 for as- suring that the antenna 18' is properly oriented with respect to the ablation site. In the illustrated em¬ bodiment, the unidirectional pivot mechanism 74 in¬ cludes a jointed assembly comprising a socket housing 76 and a ball 78 like that previously described. How- ever, unlike the fully articulated jointed assembly 26 shown in Figs. 1 to 3, the jointed 74 assembly in Fig. 11 is restricted to movement in a single range of po¬ sitions.
In Fig. 11, the shaft 80 of the ball 78 is retained within a partial slot 82. The partial slot 82 allows pivotal movement of the ball 78 within the socket housing 76 only in a plane that will orient the unidirectional antenna 18' upon the tissue with its conductor core 48 facing the tissue. This aims the unidirectional field of the antenna 18• solely at the ablation site. Because all the power supplied to the antenna 18' is directed in a single direction, the power applied to the tissue is effectively doubled, when compared to an omnidirectional antenna 18, like that shown in Figs. 5 and 6. Furthermore, the unidi¬ rectional antenna 18' minimizes the exposure of the surrounding blood pool to the electromagnetic field, because the dielectric plane 70 blocks propagation of the field radially from the ground conductor layer 72. Undesired effects of blood heating, like coagulation, are thereby minimized.
It should be appreciated that other micro¬ wave antenna structures (for example, an omnidirectional whip antenna) can be similarly at- tached to a pivot assembly at the end of a catheter to achieve the benefits of the invention.
The inventions provide a steerable microwave antenna assembly that maximizes the propagation of radiation heating patterns for deep lesion formation. The inventions are also applicable for sup¬ porting any functional element at the distal end of the catheter body 12. For example, instead of sup¬ porting a microwave antenna 18, the joint assembly can support other active elements or electrodes for tissue ablation using RF, laser, and the like. The joint assembly can also support passive monitoring elements, like one or more mapping electrodes, MAP elements, or ultrasound electrodes.
Whatever the particular function of the dis- tal element may be, the joint assembly holds the func¬ tional element with its major axis aligned with the major axis of the catheter body 12 for convenient steering to the tissue site. The joint assembly then pivots the functional element in response to an exter- nal force to orient its major axis generally parallel to the plane of the tissue site without bending the catheter body 12.
Various features and benefits of the inven¬ tions are set forth in the following claims.
