Abstract
Abstract An attachment or locking apparatus which can effectively secure an implant, such as a stent or stent graft, to a vessel or hollow organ wall and which allows minimally-invasive techniques, such as laparoscopy, to be used to attach the implant. The locking element is inserted through an anatomic vessel or hollow organ wall and the implant from outside of the vessel or hollow organ. The locking element preferably is composed of a thin retaining element and a clamping element at one end of the retaining element. A positioning device with an attached locking element may be inserted into the patient's body, such that the positioning device penetrates both the vascular or hollow organ wall and the implant deployed within the vascular or hollow organ wall. The clamping element, held within the positioning device, is then ejected into the vessel or hollow organ. The locking element is pulled tight, and then the locking element is secured into place. The locking element made be secured in place by physically deforming a portion of the retaining element outside of the vascular or hollow organ wall, by either winding or bending the retaining element.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
108 words
A method for securing an implant at a site in an anatomic wall comprising: guiding the implant to the site; making a percutaneous incision near the site; providing a tool holding at least one locking element including a clamping element and a retaining element; inserting the tool through the percutaneous incision; puncturing the exterior of the anatomic wall and the implant with a cannula; ejecting the clamping element into an interior of the anatomic wall so that a portion of the retaining element is located outside of the anatomic wall; and physically deforming the portion of the retaining element to thereby clamp the implant to the anatomic wall.
Claim 2
Independent Claim
108 words
A method for securing an implant at a site in an anatomic wall comprising: guiding the implant to the site; making a percutaneous incision near the site; providing a tool holding at least one locking element including a clamping element and a retaining element; inserting the tool through the percutaneous incision; puncturing the exterior of the anatomic wall and the implant with a cannula; ejecting the clamping element into an interior of the anatomic wall so that a portion of the retaining element is located outside of the anatomic wall; and physically deforming the portion of the retaining element to thereby clamp the implant to the anatomic wall.

Claim 9
Dependent Claim
23 words
The method of claim 1 wherein: the act of guiding the implant to the site includes guiding the implant to an anatomic vessel.
Claim 10
Dependent Claim
23 words
The method of claim 1 wherein: the act of guiding the implant to the site includes guiding the implant to a hollow organ.
Claim 11
Dependent Claim
21 words
The method of claim 1 further comprising: making an additional percutaneous incision; and inserting an endoscope through the additional percutaneous incision.
Claim 12
Dependent Claim
23 words
The method of claim 1 further comprising: making an additional percutaneous incision; and inserting at least one tool through the additional percutaneous incision.
Claim 13
Dependent Claim
16 words
The method of claim 1 wherein: the portion of the retaining element is deformed by bending.
Claim 14
Dependent Claim
26 words
The method of claim 1 wherein: the portion of the retaining element is deformed by wrapping the portion of the retaining element into a coil shape.
