US 9,168,162 B2 · Methods and apparatus for treating a type 2 endoleak from within an endoluminal stent

Abstract

A repair device includes a first elongate member, a second elongate member, and a seal member. The first elongate member includes a proximal end portion and a distal end portion and defines a lumen therebetween. The second elongate member includes a proximal end portion and a distal end portion and is movably disposed within the lumen. The distal end portion of the second elongate member is configured to puncture an endoluminal stent graft disposed within an artery of a patient and to be inserted, at least partially, into an aneurysm sac. The seal member is releasably coupled to the distal end portion of the first elongate member. The seal member is configured to be coupled to the endoluminal stent graft to seal an opening formed by the distal end portion of the second elongate member.

Dependent claims

A method, comprising:

inserting a medical device into an artery such that a distal end portion of the medical device is disposed within an endoluminal stent graft implanted within the artery near an aneurysm, the medical device including a first elongate member defining a lumen and a second elongate member movably disposable within the lumen;
moving the second elongate member distally through a seal member coupled to a distal end portion of the first elongate member such that a distal end of the second elongate member punctures the endoluminal stent graft forming an opening in the endoluminal stent graft and is disposed at least partially within the aneurysm;
injecting an agent through a lumen of the second elongate member and into the aneurysm sac;
and directly coupling the seal member to the endoluminal stent graft to seal the opening formed by the second elongate member.

A method, comprising:

inserting a medical device into an artery such that a distal end portion of the medical device is disposed within an endoluminal stent graft implanted within the artery near an aneurysm, the medical device including a first elongate member defining a lumen, a second elongate member disposed within the lumen, and a seal member releasably coupled to a distal end portion of the first elongate member with a coupling member;
moving the second elongate member distally relative to the first elongate member such that a coupling portion of the coupling member is moved distally outside of a lumen of the seal member and at least partially through the endoluminal stent graft, the coupling portion configured to assume a biased configuration when moved outside the lumen of the seal member such that the coupling portion directly couples the seal member to the endoluminal stent;
and releasing the seal member from the first elongate member.
