Delivery system with force sensor for leadless cardiac device
First Claim
1. A delivery and deployment device configured to deliver an implantable medical device (IMD) to a chamber of a patient'"'"'s heart and deploy the IMD therein, the delivery and deployment device comprising:
- a handle assembly;
a shaft extending distally from the handle assembly, the shaft including a distal region;
a device containment housing coupled to the distal region of the shaft and extending distally therefrom, the device containment housing configured to accommodate the IMD therein;
at least one of the shaft and the device containment housing including a compressible region, wherein;
when the shaft includes the compressible region, the compressible region comprises a portion of a wall of the shaft that compresses by an amount that is related to an applied force; and
when the device containment housing includes the compressible region, the compressible region comprises a portion of a wall of the device containment housing that compresses by an amount that is related to an applied force;
a first position indicator and a second position indicator, wherein at least part of the compressible region is situated between the first position indicator and the second position indicator; and
wherein a force applied to the device containment housing causes the compressible region to compress by an amount that is related to the applied force, which causes a change in distance between the first position indicator and the second position indicator, which provides an indication of the applied force.

Abstract
A device configured to deliver and deploy an implantable medical device (IMD) includes a handle assembly and a shaft extending distally therefrom. A device containment housing configured to accommodate the IMD is coupled to the distal region of the shaft. At least one of the shaft and device containment housing includes a compressible region that is configured to compress by an amount that is related to an applied force. The device may include a first position indicator and a second position indicator. An applied force causes the compressible region to compress by an amount that is related to the applied force, causing a change in distance between the first position indicator and the second position indicator and thus providing an indication of the applied force.
