Abstract
A medical device for use with an implantable lead includes a force monitoring system coupled with the device. The force monitoring system monitors force placed on the medical device and/or the lead. Optionally the system compares the force with a preset limit, and notifies a user once the preset limit has been reached.
Claims28
A method comprising:
- implanting a lead within a patient, the lead for conducting monitoring or stimulating signals through at least a portion of the patient;
- placing an extracting force on the lead with a lead extraction device and at least partially extracting the lead from the patient, the lead extraction device including a force monitoring system coupled therewith;
- and
- monitoring the extracting force placed on the lead during extraction with the force monitoring system while placing the extracting force on the lead.
1 more element
A method comprising:
- coupling a force monitoring system with a lead tunneling device;
- coupling the lead tunneling device with a lead, the lead adapted for conducting monitoring or stimulating signals through at least a portion of a patient;
- implanting at least a portion of the lead within the patient including placing a tunneling force on the lead tunneling device, tunneling through subcutaneous tissue with the tunneling device;
- and
- monitoring the tunneling force placed on the tunneling device with the force monitoring system.
2 more elements
A method comprising:
- implanting a lead within a patient with a catheter, the catheter including a force monitoring system coupled therewith, implanting the lead includes placing an implantation force on the lead thereby manipulating the lead through one or more portions of the patient;
- and
- monitoring the implantation force placed on the lead with the force monitoring system.
A medical device comprising:
- a handle portion extending from a handle distal end to a handle proximal end, the handle portion coupled with an implantable lead;
- a force monitoring system coupled with the handle portion, the force monitoring system configured to monitor force placed on the lead as the handle portion is manipulated;
- and
- an elongate body coupled with the handle.
1 more element
A medical device comprising:
- an implantable lead including conductors adapted to send electric signals through a body;
- a means for gripping the implantable lead;
- a means for measuring force placed on the implantable lead while the lead is manipulated through tissue;
- and
- a means for notifying a technician of a force measured by the means for measuring force placed on the implantable lead.
