Description
Die Erfindung betrifft eine Ballonsonde zur Thrombosie
rung von dicht unterhalb der Fläche einer schwer zugäng
lichen Körperhöhlung angeordneten Gefäßen nach dem Ober
begriff des Anspruchs 1, wie sie aus der Literaturstelle
T.V. Taylor und J.M.M. Neilson, "Currents and clots" -
an approach to the problem of acute variceal bleeding",
Br. J. Surg. Vol. 68 (1981) 692-696 bekannt ist.
Es ist bekannt, Blutungen von dicht unterhalb der Fläche
einer schwer zugänglichen Körperhöhlung angeordneten Ge
fäßen durch Thrombosierung zu stillen, indem eine Bal
lonsonde ("Sengstaken-Sonde") entblockiert in die Kör
perhöhlung eingebracht und sodann durch Einbringen eines
Fluids an Ort und Stelle geblockt wird. Die Ballonsonde
ist bei dem vorbekannten Vorschlag an ihrer Außenfläche
mit Elektroden versehen, die über einen elektrisch lei
tenden Draht mit einer Spannung versorgt werden. Als Ge
genpol dient eine großflächige, beispielsweise auf dem
Rücken des Patienten aufgelegte Elektrode. Der bei Anle
gung der Spannung entstehende Stromfluß zwischen den
beiden Elektroden bewirkt eine Thrombosierung und damit
eine Stillung der Blutung der Gefäße.
Eine derartige Thrombosierung von blutenden Gefäßen ist
insbesondere bei Ösophagusvarizen indiziert, kommt aber
auch bei anderen Körperhöhlungen in Betracht.
Die aus der genannten Literaturstelle bekannte Ballon
sonde hat sich in der Praxis nicht durchsetzen können,
da der zwischen der Elektrode und der Fläche der Körper
höhlung gebildete Widerstand nicht definiert ist.
Der Erfindung liegt damit die Aufgabe zugrunde, die vor
bekannte Ballonsonde derart weiterzubilden, daß sie den
Anforderungen der Praxis genügt, d. h. daß der zwischen der
Elektrode und der Fläche der Körperhöhlung gebildete Wider
stand einen definierten Wert aufweist.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß
das den Ballon blockierende Fluid elektrisch leitend ist
und die Ballonwandung für das Fluid teilpermeabel ist.
Vorzugsweise ist zur Stromzuführung ein durch den Schlauch geführter Draht
vorgesehen, wobei der Draht vorzugsweise als Platindraht
ausgebildet ist.
Als Fluid kommt insbesondere physiologische Kochsalzlö
sung in Betracht, auch andere elektrisch leitende Flui
de, beispielsweise ein Elektrodengel, können verwendet
werden.
Das Fluid kann dabei weiter als Medikationsträger die
nen.
Die Erfindung wird im folgenden anhand einer Zeichnung
erläutert. Dabei zeigt:
Fig. 1 eine Schnittdarstellung
durch die Ballonsonde, wobei
der obere Teil des Schlau
ches abgeschnitten ist, und
Fig. 2 eine Schnittdarstellung ent
lang der Linie II-II von
Fig. 1.
Die verwendete Ballonsonde entspricht in ihrem Erschei
nungsbild zunächst einer üblichen Sengstaken-Sonde: Sie
besteht aus einem Schlauch 10 und einem nahe dem einen
Ende des Schlauches 10 angeordneten Ballon 12, wobei der
Schlauch 10 in dem Bereich, in dem er durch den Ballon
12 geführt ist, mit Öffnungen 14 versehen ist. Durch den
Schlauch 10 ist ein Platindraht 16 geführt.
Um beispielsweise Blutungen der Ösophagusvarizen zu
stillen, wird die Ballonsonde in die Speiseröhre einge
führt, wobei der Ballon 12 entblockiert, also schlaff,
ist. Bei Erreichen des gewünschten Ortes wird ein Fluid,
beispielsweise physiologische Kochsalzlösung, in den
Schlauch eingebracht, bis diese durch die Öffnungen 14
in den Ballon 12 eintritt und diesen füllt. Durch die
teilpermeable Ausbildung der Ballonwandung 18 tritt eine
geringe Menge des elektrisch leitenden Fluids durch die
Ballonwandung 18 hindurch, so daß die Ballonwandung 18 einen
definierten und genügend kleinen elekrischen Widerstand bildet.
Eine großflächige Gegenelektrode 20 wird - bei Thrombo
sierung von Ösophagusvarizen auf den Brustbereich - auf
gebracht.
Durch Anlegen einer Spannungsquelle zwischen den Platin
draht 16 und der Gegenelektrode 20 entsteht ein Strom
fluß zwischen diesen, der bei Wahl einer geeigneten Höhe
der Spannung zwischen diesen die gewünschte Thrombosie
rung bewirkt.
Es versteht sich, daß die Vorsehung eines besonderen
Drahtes 16 nicht erforderlich ist, vielmehr kann auch
das in dem Schlauch befindliche elektrische leitende
Fluid selbst als elektrischer Leiter verwendet werden.
Als elektrisch leitendes Fluid kann statt einer physio
logischen Kochsalzlösung beispielsweise auch eine Sub
stanz entsprechend Elektrodengel verwendet werden.
Die hier vorgeschlagene Ballonsonde kann weiterhin bei
spielsweise zur Behandlung postoperativer Nachblutungen
bei Harnröhrenoperationen oder bei Blutungen im Enddarm
bereich oder aber auch bei Blutungen aus dem Nasen-
Rachenraum verwendet werden.
Es kann sich empfehlen, dem elektrisch leitenden Fluid
Medikamente zuzugeben, die über eine iontophoretische
Gewebsdiffusion blutstillend wirken.
