Method and apparatus for delivering an implant without bias to a left atrial appendage
First Claim
1. An implant delivery system, comprising:
- an implantable device comprising a plurality of supports extending between a proximal end and a distal end, the supports being moveable between a collapsed configuration and an expanded configuration;
a proximal guide tube at the proximal end of the supports extending toward the distal end; and
a distal guide tube at the distal end of the supports extending toward the proximal end;
wherein the proximal and distal guide tubes are telescoping and become further engaged as the supports move from the collapsed to the expanded configuration.

Abstract
A system and method for delivering an implant includes an implant, an actuation shaft, and a concentrically attachable disconnect mount. A distal guide tube is sometimes also provided. A proximal guide tube is also sometimes provided. The implantable device has a proximal, a distal end, and a plurality of supports. The implantable device is moveable between a collapsed and an expanded configuration. The distal guide tube, when provided, is at the distal end of the supports and extends toward the proximal end of the implantable device. The actuation shaft extends through the proximal end of the implantable device and is removeably engageable with the distal guide tube, or the distal end of the device when the distal guide tube is not provided. The disconnect mount is releasably engageable with the proximal end of the implantable device. The disconnect mount is concentrically attachable to the proximal end of the implantable device as well. The implantable device is self-expandable, and is collapsed by engaging the actuation shaft with the distal guide tube while applying a relatively proximal force to the proximal end of the implant with the disconnect mount.

15. A method of actuating an implantable device with a concentric force, the method comprising:
-
providing an implantable device having a proximal end, a distal end, and a plurality of supports extending therebetween, the implantable device configured to expand from a reduced-diameter configuration to an expanded-diameter configuration;
applying a concentric force to the proximal end; and
applying a distal force to the distal end. - View Dependent Claims (16, 17, 18, 19, 20)
