Abstract
Utility model protection is sought for a true and temporary distal endovascular occluding micro-catheter guide comprising (figure 1) a distal, inflatable and occluding micro-catheter guide body (1) with a lumen (2), a mandrel (5) made of a similar or different material, and a distal end with a connection (4) for occlusion or extension purposes, with or without the mandrel simultaneously.
Description
"SISTEMA DE PROTEÇÃO EMBÓLICA" " EMBOLIC PROTECTION SYSTEM "
A presente patente de modelo de utilidade tem por objetivo um modelo de cateter com função de servir como guia e oclusor simultaneamente para procedimentos endovasculares. Este cateter pode servir como sistema de proteção distai para prevenção de embolização durante cirurgias The present utility model patent aims at a catheter model serving as a guide and occluder simultaneously for endovascular procedures. This catheter can serve as a distal protection system to prevent embolization during surgery.
endovasculares com objetivo de melhorar a eficiência e minimizar as deficiências existentes em todas as outras guias e tipos de proteção distai. endovascular devices to improve efficiency and minimize deficiencies in all other guides and types of distal protection.
Já são conhecidos os guias atuais de diversas formas e tamanhos. Porém as guias atuais por permanecerem livres na luz vascular possibilitam lesões no endotélio vascular por trauma direto da movimentação da própria como o sistema devido a instabilidade. Não previnem embolização, podendo mesmo ser, inclusive, responsável pela intercorrência. Current guides of various shapes and sizes are already known. However, the current guidelines for being free in the vascular lumen allow injuries to the vascular endothelium due to direct trauma of the own movement as the system due to instability. They do not prevent embolization and may even be responsible for complications.
Tendo em vista todos estes inconvenientes supracitados e com o propósito de possibilitar a realização de procedimentos endovasculares com a segurança devida e necessária, foi desenvolvido um novo modelo de guia que consiste na criação de um microcateter guia oclusor distai endovascular verdadeiro e temporário cujo princípio básico de ação para proteção a oclusão distai e assim estabilização do todo o sistema. In view of all the above drawbacks and in order to enable endovascular procedures to be performed with due and necessary safety, a new guide model consisting of the creation of a true and temporary distal endovascular occluder guide catheter was developed whose basic principle of action for distal occlusion protection and thus stabilization of the whole system.
Esse tipo de dispositivo é constituído por uma família de microcateteres de diferentes tamanhos e materiais que podem ser utilizados em qualquer tipo de cirurgia endovascular que utilize as atuais guias endovasculares. This type of device consists of a family of microcatheters of different sizes and materials that can be used in any type of endovascular surgery using current endovascular guides.
Inicialmente os diâmetros dessa família sugeridos são 0.0010", 0.0014", 0.00 8" e 0.0035" compatíveis com as atuais. Initially the suggested diameters of this family are 0.0010 " , 0.0014 " , 0.00 8 "and 0.0035" compatible with the current ones.
O microcateter guia balão dista! oclusor endovascular causará uma oclusão temporária e servirá de guia para os sistemas endovasculares sobre ele durante todo o procedimento. Sua compatibilidade com todas as guias permite seu uso por todas as já existentes. The microcatheter guide balloon distal! The endovascular occlusion will cause a temporary occlusion and will guide the endovascular systems over it throughout the procedure. Its compatibility with all tabs allows its use by all existing ones.
Dessa forma resolvem-se os problemas da instabilidade do sistema e trauma direto da guia além do risco menor de vasoespasmo. This solves the problems of system instability and direct trauma to the guide and the lower risk of vasospasm.
O desenho em anexo mostram o microcateter guia oclusor distai endovascular objeto da presente patente no qual:
A figura 1 mostra microcateter guia oclusor distai endovascular em corte longitudinal e transversal (A-A). The attached drawing shows the endovascular distal occlusive guide microcatheter object of the present invention in which: Figure 1 shows endovascular distal occlusive guide microcatheter in longitudinal and transverse section (AA).
De conformidade com o quanto ilustra a figura relacionada, o modelo de utilidade da presente patente consiste em uma família de cateteres sendo de estrutura similar diferindo no perfil (escala) e tipo de material utilizado na confecção. As illustrated by the related figure, the utility model of the present invention consists of a family of catheters of similar structure differing in the profile (scale) and type of material used in the confection.
A figura 1 representa o microcateter guia oclusor distai endovascular que consiste em um corpo 3 com um balão distai 1 na extremidade interna(ou proximal) dotado de uma luz 2 que possibilita a insuflação do balão distai 1. A extremidade externa (ou distai) possui uma conexão 4 do referido cateter que possibilita a entrada para a luz 2 com objetivo de insuflar o balão 1 , ocluir a extremidade e/ou permitir a sua extensão 5 com preenchimento ou não da luz 2. Desse modo configura maior flexibilidade ou triihagem aos cateteres que virão sobre este durante o procedimento com a estabilidade necessária. A oclusão do local tratado simultâneamente impede a embolização.
Figure 1 is the endovascular distal occluder guide microcatheter consisting of a body 3 with a distal balloon 1 at the inner (or proximal) end provided with a light 2 enabling insufflation of the distal balloon 1. The outer (or distal) end has a connection 4 of said catheter that allows light 2 to inflate balloon 1, occlude the end and / or allow its extension 5 with or without light 2 filling. Thus it configures greater flexibility or triple the catheters that will come over this during the procedure with the required stability. Occlusion of the treated site simultaneously prevents embolization.
