Abstract
Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The distal holding section may be structured to have portions that flex and bend while allowing the implantable device to be recaptured within the distal holding section.
Claims20
A delivery device for delivering an implantable leadless pacing device, the delivery device comprising:
- a proximal elongate shaft having an outer diameter;
- a distal holding section extending distally of a distal end of the proximal elongate shaft, the distal holding section having an outer diameter greater than the outer diameter of the proximal elongate shaft, the distal holding section defining a cavity therein for receiving an implantable leadless pacing device;
- and
- wherein the distal holding section comprises a predefined curved portion along a length thereof such that a central axis of the distal holding section is curved.
A delivery device for delivering an implantable leadless pacing device, the delivery device comprising:
- an elongate shaft having an outer diameter and a lumen extending therethrough;
- a distal end of the elongate shaft defining a distal holding section having an outer diameter greater than an outer diameter of a remainder of the elongate shaft;
- a push member slidably disposed in the lumen of the elongate shaft;
- wherein the distal holding section defines a cavity therein for receiving an implantable leadless pacing device and a distal opening for expelling the implantable leadless pacing device therefrom;
- and
- wherein the distal holding section comprises a predefined curved portion along a length thereof.
A delivery device for delivering an implantable leadless pacing device, the delivery device comprising:
- a proximal elongate shaft having an outer diameter;
- a distal holding section extending distally of a distal end of the proximal elongate shaft, the distal holding section having an outer diameter greater than the outer diameter of the proximal elongate shaft, the distal holding section defining a cavity therein for receiving an implantable leadless pacing device;
- wherein the distal holding section comprises a reinforcing element covered by a polymeric body;
- and
- wherein a proximalmost end of the reinforcing element is disposed within the distal holding section.
