Abstract
A method for testing the pulsatile endurance of a vascular implant 3 comprises placing a resilient insert 4 into the implant and repeatedly expanding and contracting the insert, thereby expanding and contracting the implant. The insert preferably has a cavity therein and is repeatedly expanded and contracted by repeatedly increasing and decreasing the pressure in the cavity.

1-21. (canceled)
A method for testing pulsatile endurance of a vascular implant comprising:
- a. providing a resilient insert,
- b. inserting the insert into the vascular implant, and
- c. repeatedly expanding and contracting the insert, thereby expanding and contracting the implant.
A device for testing pulsatile endurance of a vascular implant comprising:
- a. a resilient insert having a cavity therein,
- b. means for repeatedly increasing and decreasing the pressure in the cavity in order repeatedly to expand and contract the insert, thereby repeatedly expanding and contracting the implant into which, in use, the insert is inserted.
A device for testing pulsatile endurance of a vascular implant comprising a resilient insert having a cavity therein, wherein:
- a. the vascular implant is fit about the resilient insert, and
- b. the insert is repeatedly flexed by pressure variations in the cavity, wherein the insert bears against the interior of the vascular implant during flexure.
