Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
247 words
A method for delivering a percutaneous stent-graft to a patient, the method comprising: a) inserting a first vascular access means into a first body lumen section of the patient; b) inserting a second vascular access means into a second body lumen section of the patient; c) providing an apparatus comprising a body implantable device comprising a self-expanding flexible tube of open weave construction having a first end and a second end, the ends being compressible into a radially compressed state, the flexible tube having an elastic layer arranged along at least a portion of its length, first and second removable retaining elements secured to the flexible tube proximate the first and second ends, respectively, for maintaining the first and second ends in radially compressed states, the retaining elements being adapted for insertion into the first and second vascular access means; d) inserting the first and second removable retaining elements into the first and second vascular access means, respectively; e) pushing the first and second removable retaining elements into the first and second vascular access means, respectively, until at least part of the flexible tube first end is disposed within the first body lumen and at least part of the flexible tube second end is disposed within the second body lumen; f) removing the first and second vascular access means; and g) removing the first and second retaining means thereby allowing the first and second end sections to expand within the first and second body lumen sections, respectively.
Claim 2
Independent Claim
247 words
A method for delivering a percutaneous stent-graft to a patient, the method comprising: a) inserting a first vascular access means into a first body lumen section of the patient; b) inserting a second vascular access means into a second body lumen section of the patient; c) providing an apparatus comprising a body implantable device comprising a self-expanding flexible tube of open weave construction having a first end and a second end, the ends being compressible into a radially compressed state, the flexible tube having an elastic layer arranged along at least a portion of its length, first and second removable retaining elements secured to the flexible tube proximate the first and second ends, respectively, for maintaining the first and second ends in radially compressed states, the retaining elements being adapted for insertion into the first and second vascular access means; d) inserting the first and second removable retaining elements into the first and second vascular access means, respectively; e) pushing the first and second removable retaining elements into the first and second vascular access means, respectively, until at least part of the flexible tube first end is disposed within the first body lumen and at least part of the flexible tube second end is disposed within the second body lumen; f) removing the first and second vascular access means; and g) removing the first and second retaining means thereby allowing the first and second end sections to expand within the first and second body lumen sections, respectively.
Claim 3
Dependent Claim
22 words
The method of claim 1 further comprising the step of tunnelling between two incisions to create a percutaneous path for the stent-graft.
Claim 4
Dependent Claim
41 words
The method of claim 1 wherein the first and second vessel segments comprise lumens having an internal surface and the body implantable device has at least one barb configured for engaging the internal surface of the first and second vessel segments.
