Method and system for treating aneurysms

A method for treating an abdominal aortic aneurysm between a pair of iliacs and a pair of renal arteries in an aorta of a patient, said method comprising:

• positioning a first double-walled filling structure on a first endoframe from one iliac artery and an artery access site, across the aneurysm, and into the aorta beneath the renal arteries, wherein the first endoframe shapes an entire length of a first tubular lumen;
• positioning a second double-walled filling structure on a second endoframe from the other iliac artery of the pair and another artery access site, across the aneurysm, and into the aorta beneath the pair of renal arteries and adjacent to the first double-walled filling structure, wherein the second endoframe shapes an entire length of a second tubular lumen;
• expanding said first endoframe and said second endoframe to create a first expanded tubular lumen and a second expanded tubular lumen, each having a shape;
• simultaneously filling the first filling structure and the second filling structure with a fluid filling medium so that an outer wall of each of the first filling structure and the second filling structure conform to an inside surface of the aneurysm and to each other, and so that an inner wall of the first filling structure and the second filling structure each form a generally tubular lumen with a shape defined by the expanded first tubular lumen and the expanded second tubular lumen from the first iliac and the second iliac, respectively, through the aorta beneath the renal arteries;
• simultaneously hardening the fluid filling medium in the first filling structure and the second filling structure while the first endoframe continues to define the shape of the expanded first tubular lumen and the second endoframe continues to define the shape of the expanded second tubular lumen.

A method of treating an aortic aneurysm using two catheters each have a sheath holding compressed within it one or more expandable endobags in fluid communication with one another and an endobag fill line surrounding a compressed endoframe comprising the steps of:

• threading a catheter of the two catheters into each of two separate femoral arteries of patient to be treated and into the aorta with a common end of each endoframe of said catheters being positioned near a proximal end of an aneurysmal sac of the aneurysm to be treated, wherein a proximal end of each of said endoframes are positioned adjacent one another before expansion of the endoframes in a configuration ensuring substantially unobstructed blood flow through each lumen of said expanded endoframes;
• wherein said common end of said endoframes are at level and at a location and a level in the aorta that is substantially the same and is adjacent to an intended landing of the common ends of the endoframes;
• removing the sheath exposing the expandable endobag and expanding the compressed endoframe of each of the two catheters;
• establishing communication between a fill line for an expandable endobag of a first of the two catheters and a fill line for an expandable endobag of a second of the two catheters and a curable filler material source to form an endobag filler circuit;
• monitoring and controlling the pressure within said endobag filler circuit while using a common source of curable filler material to pressurize said endobag filler circuit thereby simultaneously pressurizing the fill line for each expandable endobag of the two catheters causing the expandable endobags disposed across the aneurysm within the patient to inflate to fill the aneurysm and press against each other and the aneurysmal wall, wherein controlling the pressure within said endobag filler circuit consists of filling at a filling pressure in the endobag filler circuit until a maximum of the filling pressure reading monitored during pressurization is at least equal to a systolic blood pressure of the patient being treated, wherein the maximum pressure reading monitored during pressurization is established when curable filler material injection causing said pressurizing of said endobag filler circuit is stopped and a steady state endobag circuit pressure is measured;
• maintaining the filling pressure within said endobag filler circuit for a curing time allowing said curable filler material to cure;
• detaching said endobag fill lines from their respective endobags and removing the two catheters from the patient.

A system for treating an aneurysm comprising:

• a first catheter and a second catheter each catheter having an endobag, the endobag comprising a double-walled filling structure with an aneurysm conforming outer wall and a blood transit lumen creating inner wall surrounding an endoframe releasably coupled to the catheter and held compressed in an unexpanded configuration by a retractable sheath, wherein an endobag pressurization piping has one end releasably coupled to said endobag and has an inner lumen in communication with the inside of said endobag with the other end of said endobag pressurization piping extending within the sheath and in communication with endobag pressurization tubing outside the catheter, wherein an inside of an endoframe expanding non-compliant balloon is in communication with endoframe pressurization tubing outside of the catheter;
• and wherein a guidewire lumen of the catheter is in communication with guidewire lumen pressurization tubing extending outside of the catheter;
• a sequential manifold console having two endobag pressurization tubing outlet ports, two endoframe pressurization tubing outlet ports, and two guidewire lumen pressurization outlet ports wherein one of said two ports are connectable to said ends of said corresponding pressurization tubing outside of both said first catheter and said second catheter;
• the manifold console further having sequential inlet ports, wherein a first inlet port communicates with said two endobag pressurization tubing outlet ports, wherein a second inlet port communicates with said two endoframe pressurization tubing outlet ports, and wherein a third inlet port communicates with said two guidewire lumen pressurization outlet ports, wherein when said tubing ends from said first and said second catheters are connected to said corresponding manifold console outlet ports, pressurization of the corresponding inlet port equally pressurizes the corresponding pressure containing passage in both said first catheter and said second catheter simultaneously;
• wherein the first, second, and third inlet ports are configured in a side by side sequential configuration, where the sequential configuration of first, second, and third ports is arranged to match a desired sequence of an operator's steps of pressure application to said first and second catheter endobag pressurization, endoframe pressurization, and guidewire lumen pressurization tubing.

A sequential manifold console comprising:

• two guidewire lumen pressurization outlet ports,
• wherein at least one of said two ports are connectable to an end of corresponding pressurization tubing outside of both a first catheter and a second catheter;
• the manifold console further having sequential inlet ports, wherein a first inlet port communicates with said two endobag pressurization tubing outlet ports, wherein a second inlet port communicates with said two endoframe pressurization tubing outlet ports, and wherein a third inlet port communicates with said two guidewire lumen pressurization outlet ports, wherein when said tubing ends from said first and said second catheters are connected to said corresponding manifold console outlet ports, pressurization of the corresponding inlet port equally pressurizes a corresponding pressure containing passage leading to both the first catheter and the second catheter simultaneously;
• wherein the first, second, and third inlet ports are configured in a side by side sequential configuration, where the sequential configuration of first, second, and third ports is arranged to match a desired sequence of an operator's steps of pressure application to the connectable first and second catheter endobag pressurization, endoframe pressurization, and guidewire lumen pressurization tubing.
