Abstract
Embodiments include, for example, mechanical release systems for implantable medical devices.
Claims25
A system comprising:
- an implant including a shape memory polymer (SMP) non-releasably coupled to a collar;
- a distal actuator wire, a retention wire, a proximal actuator wire, and a shaft that couples the distal actuator wire to the proximal actuator wire;
- a coil that includes the distal actuator wire but not the retention wire;
- a first conduit:
- (a) releasably coupled to the collar, and (b) including the distal actuator wire and the retention wire but not the coil;
- a second conduit:
- (a) releasably coupled to the collar, and (b) including the distal actuator wire, the retention wire, and the coil;
- wherein:
- the collar includes a channel, a first aperture, and a second aperture that is located in a sidewall of the collar;
- the distal actuator wire is:
- (a) included within the channel, and (b) traverses the first aperture but not the second aperture;
- the retention wire is:
- (a) included within the channel, and (b) traverses the first and second apertures.

A system comprising:
- a medical implant including a channel, a first aperture, and a second aperture that is located in a sidewall of the medical implant;
- a first wire, a second wire, a third wire, and a shaft or wire that couples the first wire to the third wire;
- a coil that includes the first wire but not the second wire;
- a first conduit:
- (a) releasably coupled to the medical implant, and (b) including the first wire and the second wire but not the coil;
- a second conduit:
- (a) releasably coupled to the medical implant, and (b) including the first wire, the second wire, and the coil;
- wherein:
- the first wire is:
- (a) included within the channel, and (b) traverses the first aperture but not the second aperture;
- the second wire is:
- (a) included within the channel, and (b) traverses the first and second apertures.
