Delivery devices and methods for leadless cardiac devices
First Claim
1. A delivery device for delivering an implantable leadless pacing device, the delivery device comprising:
- an intermediate tubular member including a lumen extending from a proximal end to a distal end thereof;
an inner tubular member including a lumen extending from a proximal end to a distal end thereof, the inner tubular member slidably disposed within the lumen of the intermediate tubular member;
a distal holding section extending distally of a distal end of the intermediate tubular member, the distal holding section defining a cavity therein for receiving an implantable leadless pacing device;
a handle assembly including at least an intermediate hub portion affixed adjacent to the proximal end of the intermediate tubular member and a proximal hub portion affixed adjacent to the proximal end of the inner tubular member;
a longitudinally extending groove having a proximal end and a distal end disposed in an outer surface of the intermediate hub portion, wherein the distal end of the groove is circumferentially offset from the proximal end of the groove; and
a multi-stage deployment mechanism disposed within the handle assembly;
wherein the multi-stage deployment mechanism is configured to incrementally deploy an implantable leadless pacing device.

Abstract
Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include an intermediate tubular member and an inner tubular member slidably disposed within a lumen of the intermediate tubular member. A distal holding section may extend distally of a distal end of the intermediate tubular member and define a cavity therein for receiving an implantable leadless pacing device. The device may further include a handle assembly including at least an intermediate hub portion affixed adjacent to the proximal end of the intermediate tubular member and a proximal hub portion affixed adjacent to the proximal end of the inner tubular member. A longitudinally extending groove having a proximal end and a distal end may be disposed in the intermediate hub portion. A first locking mechanism may be configured to releasably couple the intermediate hub portion and the proximal hub portion.
