Delivery (and recovery) devices and techniques for delivering an implant into a desired location within the body and catch systems for such implants. The devices and techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube. A catch system maintains an occluder in a deployed configuration by holding it in a reduced axial length position. Some embodiments have a compressible tip. Some embodiments have temporary catching mechanisms.

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: a bioresorbable 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 a first inner diameter at the proximal end and a second inner diameter at the distal end;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 portion 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 first inner diameter of the axial passage of the occluder portion; and,wherein the proximal portion of the catch body of the catch member further comprises two compressible prongs each comprising a proximal tip and a proximal ridge on a surface of the prong, 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 prongs are held in a compressed position and to engage the proximal end of the occluder portion thereby holding the medical device in the second configuration. 2. The collapsible medical device of claim 1, wherein the occluder portion is a bioresorbable polymer. 3. The collapsible medical device of claim 2, wherein the bioresorbable polymer is poly-4-hydroxy-butyrate (P4HB). 4. The collapsible medical device of claim 1, wherein the occluder portion is a bioresorbable metal. 5. The collapsible medical device of claim 1, wherein further the proximal collapsible tip is threaded. 6. 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: a bioresorbable occluder portion movable between the first and the second configuration, wherein the occluder portion comprises a proximal end and proximal portion having a proximal axial passage therethrough with an inner diameter, a distal end and a distal portion having a distal axial passage therethrough with an inner diameter, and a central tube between the proximal end and the distal end; anda catch member adapted to be disposed in the axial passages of the occluder portion, wherein the catch member comprises a catch body having an outer surface; a proximal section comprising a proximal collapsible tip, a proximal ridge adjacent the proximal collapsible tip and a slot disposed at the proximal collapsible tip to render it collapsible; and a distal section comprising 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 the distal section having a first outer diameter D1 and the proximal section having a second outer diameter D2 joined by a sloped section, wherein diameter D2 is similar to the inner diameter of the proximal axial passage of the occluder portion; and,wherein the proximal collapsible tip is adapted for connection to a delivery system; and the proximal ridge is adapted to pass through the proximal axial passage of the occluder portion while the proximal collapsible tip is held in a collapsed position to enable delivery and deployment of the occluder. 7. The collapsible medical device of claim 6, wherein the occluder portion is a bioresorbable polymer. 8. The collapsible medical device of claim 7, wherein the bioresorbable polymer is poly-4-hydroxy-butyrate (P4HB). 9. The collapsible medical device of claim 6, wherein the occluder portion is a bioresorbable metal. 10. The collapsible medical device of claim 6, wherein further the proximal collapsible tip is threaded.
