Abstract
A catheter system for implanting a lead for cardiac conduction system is provided. The catheter system includes a catheter having an orifice extending from a distal end of the catheter to a proximal end of the catheter for implanting the lead, and a probe extending through the catheter. The probe includes a conductive wire covered with an insulation layer. A distal end of the wire is exposed from the insulation layer. The distal end of the wire includes a wire electrode configured to conduct pacing prior to implanting the lead.
Claims20
A catheter system for implanting a lead for cardiac conduction system, the catheter system comprising:
- a catheter having an orifice extending from a distal end of the catheter to a proximal end of the catheter for implanting the lead;
- and
- a probe extending through the catheter,
- wherein the probe includes a conductive wire covered with an insulation layer, a distal end of the wire is exposed from the insulation layer,
- the distal end of the wire includes a wire electrode configured to conduct pacing prior to implanting the lead.
A method of implanting a lead for cardiac conduction system using a catheter system, the method comprising:
- inserting a catheter to reach interventricular septum;
- placing a probe to reach and electrically map the cardiac conduction system, the probe including a conductive wire covered with an insulation layer, a distal end of the wire being exposed from the insulation layer, the distal end of the wire including a wire electrode;
- dispositioning the probe into the interventricular septum;
- conducting pacing through the probe to the interventricular septum;
- conducting sensing to obtain electrocardiogram during or after the pacing;
- adjusting a location of the probe based on the obtained electrocardiogram;
- inserting the lead through an orifice of the catheter extending from a distal end of the catheter to a proximal end of the catheter;
- and
- placing a distal end of the lead to the adjusted location such that an entirety of the distal end of the lead is inserted inside the interventricular septum.
