Abstract

Apparatus for delivering a medical device to a location in a patient'"'"'s body includes an elongate catheter body having a proximal end and a distal end, a pod coupled with the distal end of the catheter body and adapted to house the medical device during delivery to the location and to open to release the medical device, and at least one distal actuator coupled with at least one of the pod and the medical device. The distal actuator is adapted to promote opening of the pod. A method involves advancing a pod at the distal end of an elongate catheter to the location within the body and activating an actuator coupled with the pod and/or the medical device to cause the pod to open. Opening the pod releases the medical device.

Claims

1. An apparatus for delivering a medical device to a location in a patient'"'"'s body comprising:

an elongate catheter body having a proximal end and a distal end;

an encasing coupled with the distal end of the catheter body and adapted to house the medical device during delivery to the location and to eject the medical device to release;

at least one actuator coupled with at least one of the encasing and the medical device, the actuator adapted to promote opening of the encasing;

an inner shaft which is translatable relative to the encasing such that translation of the inner shaft releases a distal portion of the medical device from an elongate low-profile configuration to a helical configuration,

wherein the encasing comprises a material disposed over the medical device.

2. The apparatus of claim 1, wherein the encasing comprises of at least two opposed housing members for releasably housing the medical device.

3. The apparatus of claim 2, wherein the housing members comprise a material selected from the group consisting of a polymer, a ceramic, a metal, a composite and a biological material.

4. The apparatus of claim 1 further comprising a cutting member selected from the group comprising of blades, rip chords, wires, threads, wedges, and inflation devices.

5. The apparatus of claim 1, wherein the encasing defines perforations to promote tearing or peeling of the material.

6. The apparatus of claim 1, wherein the inner shaft is rotatable relative to the encasing.

7. The apparatus of claim 6, wherein inner shaft is keyed to move relative to the medical device.
