Delivery devices and methods for leadless cardiac devices
First Claim
1. A delivery system for delivering an implantable leadless pacing device, the delivery system comprising:
- an implantable leadless pacing device including a housing having a proximal end, a distal end, and a cylindrical outer peripheral surface having a constant outer diameter; and
a delivery device including;
a proximal section including a distal end,a distal holding section extending distally of the distal end of the proximal section, the distal holding section includes an annular wall having an inner surface defining a cavity therein for receiving the implantable leadless pacing device, the distal holding section being configured to apply a compressive force to and conform to the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device when the implantable leadless pacing device is disposed in the cavity,wherein the inner surface presses circumferentially against the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device when the implantable leadless pacing device is disposed in the cavity, andwherein there is no gap or opening between the inner surface of the distal holding section and an entirety of the cylindrical outer peripheral surface of the housing;
wherein when the implantable leadless pacing device is fully disposed in the cavity, the distal holding section includes a distally facing opening distal of the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device, the distal opening having an inner diameter that is less than the outer diameter of the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device;
wherein the distal opening is configured to expand as the housing of the implantable leadless pacing device passes therethrough.

Abstract
Delivery devices, systems, and methods for delivering an implantable leadless pacing device having an outer peripheral surface are disclosed. An example delivery device may include a proximal section including a distal end, and a distal holding section extending distally of a distal end of the proximal section. The distal holding section defines a cavity therein for receiving the implantable leadless pacing device, and may be configured to apply a holding force to the implantable leadless pacing device. In some cases, the distal holding section may be configured to apply a compressive force to the outer peripheral surface of the leadless pacing device when the leadless pacing device is disposed in the cavity.

10. A delivery system for delivering an implantable leadless pacing device, the delivery system comprising:
-
an implantable leadless pacing device including; a housing including electrical circuitry therein, the housing having a cylindrical outer peripheral surface having a constant outer diameter; and a fixation mechanism disposed at a distal end of the housing; a delivery device including; a proximal section including a distal end, and a distal holding section extending distally of a distal end of the proximal section, the distal holding section includes an annular wall having an inner surface defining a cavity therein for receiving the implantable leadless pacing device, the distal holding section being configured to conform to the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device when the implantable leadless pacing device is disposed in the cavity to provide circumferential frictional engagement with the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device, wherein the inner surface circumferentially frictionally engages the cylindrical outer peripheral surface of the housing of the implantable leadless pacing device when the implantable leadless pacing device is disposed in the cavity while being free of any gap between the inner surface and the cylindrical outer peripheral surface of the housing. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
