Abstract
A endovascular graft having at least two thin wall graft members, with at least one of the thin wall graft members configured to be deployed within a lumen of another thin wall graft member. The thin wall graft members may be coupled or connected to each other so as to allow relative axial displacement of the sections, or they may be separate members that have dimensions and a configuration to allow coaxial deployment within inner lumens of each other. By having multiple thin wall graft member, the graft may be built up within a patient's vasculature in steps through a delivery catheter system that is smaller in profile and more flexible than a delivery catheter system configured to deliver a single component graft. The graft of the invention may be delivered percutaneously or intraoperatively.
Claims22
An endovascular graft adequate for maintaining a flow of blood therethrough and preventing leakage or failure of a compromised portion of a patient's body lumen comprising a plurality of individually deliverable thin wall graft members layered in a deployed state with at least two layers of thin wall graft member present across an entire length of the compromised portion of the patient's body lumen.
A method of deploying an endovascular graft adequate for maintaining a flow of blood therethrough and preventing leakage or failure of a compromised portion of a patient's body lumen within the patient's body lumen, comprising:
- a) providing an endovascular graft comprising at least two thin wall graft members configured to be layered in a deployed state;
- b) percutaneously delivering a first thin wall graft member individually through a low profile delivery catheter system to the compromised portion of the patient's body lumen;
- c) percutaneously delivering at least one additional thin wall graft member through a low profile delivery catheter system and positioning the at least one additional thin wall graft member within a longitudinal lumen of the first thin wall graft member so as to at least partially axially overlap the first thin wall graft member;
- and
- d) deploying the first thin wall graft member and the at least one additional thin wall graft member until the first and at least one additional thin wall graft members are in a desired configuration within the passageway of the patient with at least two layers of thin wall graft member present across an entire length of the compromised portion of the patient's body lumen.
The method of claim 11 wherein an inner most thin wall graft member extends longitudinally beyond the other thin wall graft member or members and engages the patient's body lumen directly.
A kit with components suitable for forming an endovascular graft adequate for maintaining a flow of blood therethrough and preventing leakage or failure of a compromised portion of a patient's body lumen comprising a plurality of individually deliverable thin wall graft members configured to be layered in a deployed state with at least two layers of thin wall graft member present across an entire length of the compromised portion of the patient's body lumen.
An endovascular graft adequate for maintaining a flow of blood therethrough and preventing leakage or failure of a compromised portion of a patient's body lumen comprising a plurality of thin wall graft members that are linked so as to allow relative longitudinal movement therebetween and that are configured to be layered in a deployed state with at least two layers of thin wall graft member present across an entire length of the compromised portion of the patient's body lumen.
A method of deploying an endovascular graft adequate for maintaining a flow of blood therethrough and preventing leakage or failure of a compromised portion of a patient's body lumen within the patient's body lumen, comprising:
- a) providing an endovascular graft comprising at least two thin wall graft members configured to be layered in a deployed state;
- b) percutaneously delivering a first thin wall graft member through a low profile delivery catherer system to a desired site within the patient's body lumen and deploying the first thin wall graft member axially coextensive with at least a portion of the compromised portion of the patient's body lumen;
- c) percutaneously delivering at least one additional thin wall graft member through a low profile delivery catherer system and positioning the at least one additional thin wall graft member at least partially within a longitudinal lumen of the deployed first thin wall graft member;
- and
- d) deploying the at least one additional thin wall graft member within the longitudinal lumen of the deployed first thin wall graft member such that there are at least two layers of thin wall graft member present across an entire length of the compromised portion of the patient's body lumen.
An endovascular graft adequate for maintaining a flow of blood therethrough comprising a plurality of separate thin wall graft members having thin graft material supported by and secured to a support structure and the members layered in a deployed state with at least two layers of thin wall graft member present across an entire length of a compromised portion of a patient's body lumen.
A method of deploying an endovascular graft adequate for maintaining a flow of blood therethrough within a patient's body lumen, comprising:
- a) providing an endovascular graft comprising at least two thin wall graft members configured to be layered in a deployed state;
- b) percutaneously delivering the at least two thin wall graft members longitudinally extended from each other through a low profile delivery catherer system to a desired site within the patient's body lumen;
- and
- c) deploying the at least two thin wall graft members such that there are at least two layers of thin wall graft member present across an entire length of a compromised portion of the patient's body lumen.
A method of deploying an endovascular graft adequate for maintaining a flow of blood therethrough, comprising;
- a) providing an endovascular graft comprising at least two thin wall graft members configured to be layered in a deployed state;
- b) percutaneously delivering a first thin wall graft member through a low profile delivery catherer system to a desired site within a patient's body lumen and deploying the first thin wall graft member;
- c) percutaneously delivering at least one additional thin wall graft member to a desired site within the patient's body lumen through a low profile delivery catherer system;
- and
- d) deploying the at least one additional thin wall graft member such that there are at least two layers of thin wall graft members present across an entire length of a compromised portion of the patient's body lumen.
