1. A collapsible medical device for occluding an aperture in a body, the medical device having a first configuration as a reduced profile and a second configuration as an expanded profile, the medical device being adapted to be delivered through a delivery system into a desired delivery location, the medical device comprising:
an occluder portion movable between the first and the second configuration, wherein the occluder portion comprises a proximal end, a distal end, and an axial passage between the proximal end and the distal end, the axial passage having an inner diameter;
a catch member adapted to be disposed in the axial passage of the occluder portion, wherein the catch member comprises a catch body having a proximal collapsible tip, a proximal ridge adjacent the collapsible tip, a slot disposed at the proximal tip to render it collapsible, and a distal flange;
wherein the distal flange of the catch member engages the distal end of the occluder portion,
wherein the catch body has a tapered or graduated cylindrical profile composed of a distal section having a first diameter D1 and a proximal section having a second diameter D2 joined by a sloped section, wherein diameter D2 is similar to the inner diameter of the axial passage of the occluder portion; and,
wherein the proximal tip is adapted for connection to a delivery system; and the proximal ridge is adapted to pass through the axial passage of the occluder portion while the compressible tip is held in a compressed position to enable delivery and deployment of the occluder.
2. The medical device recited in claim 1, wherein the catch member is made of polymeric material.
3. The medical device recited in claim 1, wherein the proximal ridge on the catch body has a stepped profile above the surface of the catch body.
4. The medical device recited in claim 1, wherein the catch body is so dimensioned that the catch body and the passage have an interference fit.
The claims below are in addition to those above.
