METHOD AND SYSTEM FOR TREATING ANEURYSMS

摘要

Methods for treatment of aneurysms using a sequential manifold console to deploy multiple filling structures are provided herein. In one aspect, aneurysms are treated by simultaneously filling two double-walled filling structure using a sequential manifold console to guide a user in the steps to be followed in the procedure and to reliably achieve a consistent and durable aneurysmal treatment using a curable medium. The structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Pairs of filling structures delivered to the aneurysm from different access openings of a patient can be simultaneously prepared and pressurized from a single treatment console when treating abdominal aortic aneurysms using the described systems and methods.

1. A system for treating an aneurysm comprising:
a first catheter and a second catheter each catheter having an endobag comprising a double-walled filling structure with an aneurysm conforming outer wall and a blood transit lumen creating an inner wall surrounding an endoframe releasably coupled to the respective catheter, each of the first and second catheters includes an endobag pressurization piping having one end releasably coupled to the respective endobag and an inner lumen in communication with the respective endobag with the other end of the respective endobag pressurization piping in communication with an endobag pressurization tubing outside the respective catheter, each of the first and second catheters includes a balloon on which the respective endoframe is mounted so as to expand the endoframe when inflated, each balloon being in communication with an endoframe pressurization tubing outside of the respective catheter, and each of the first and second catheters comprises a guidewire lumen in communication with a guidewire lumen pressurization tubing extending outside the respective catheter; and a manifold console having two endobag pressurization tubing outlet ports, two endoframe pressurization tubing outlet ports, and two guidewire lumen pressurization outlet ports, the two endobag pressurization tubing outlet ports being connectable to the corresponding ends of the endobag pressurization tubing of the endobags of the first and second catheters, the two endoframe pressurization tubing outlet ports being connectable to the corresponding ends of the endoframe pressurization tubing of the first and second catheters, and the two guidewire lumen pressurization outlet ports being connectable to the corresponding ends of the guidewire lumen pressurization tubing of the first and second catheters; the manifold console further having a series of inlet ports including a first inlet port in communication with the two endobag pressurization tubing outlet ports, a second inlet port in communication with the two endoframe pressurization tubing outlet ports, and a third inlet port in communication with the two guidewire lumen pressurization outlet ports, the manifold console being configured so that when the endobag pressurization and endoframe pressurization tubing ends from the first and the second catheters are connected to the corresponding manifold console outlet ports pressurization of the first inlet port equally pressurizes corresponding endobag pressurization tubing to both the first and second catheters simultaneously and pressurization of the second inlet port equally pressurizes corresponding endoframe pressurization tubing to both the first catheter and the second catheter simultaneously.
