Abstract

A member of a rigid flexible elastic material, the member including a body portion and an aperture portion with the member adapted for delivery through an axial longitudinal channel of a percutaneous delivery subsystem, the aperture portion including an expanded mode having a lateral dimension greater than an inner diameter of the channel when the aperture portion extends outside the channel and a collapsed mode wherein the lateral dimension is not greater than the inner diameter of the channel when the aperture portion is within the channel, the channel including a first axial opening and a second axial opening with the aperture portion transitioning from the expanded mode to the collapsed mode when inserted into the openings and the aperture transitioning from the collapsed mode to the expanded mode when exiting from the openings.

Dependent claims

A method comprising the steps of:

inserting a percutaneous structure no greater than 18 gauge into a body portion by piercing said body portion with a sharp tip of said structure, said structure including a channel having a first opening positioned outside said body portion and a second opening positioned inside said body portion;
delivering a member into said channel, said member formed by a pair of shape memory alloy elements wound about each other and having an aperture portion including an aperture between said elements, said aperture is collapsed when inserted into said first opening;
extending said aperture portion out of the second opening to automatically expand said aperture to form a predetermined perimeter having N number of hard discrete bends, wherein N is an even number that is 6 or greater.

Dependencies are inferred from the claim text.
