Abstract
A myotomy catheter for performing longitudinal myocardial incisions is provided. In one example, a catheter-based heart incision apparatus comprises an anchor stabilization and orientation catheter system with at least one anchor element and an incision catheter including a lacerator configured to move along an incision trajectory oriented by the at least one anchor element.
Claims21
A catheter-based heart incision apparatus, comprising:
- an anchor stabilization and orientation catheter system with at least one anchor element;
- and
- an incision catheter including a lacerator configured to move along an incision trajectory oriented by the at least one anchor element.
A catheter-based heart incision apparatus, comprising:
- an incision catheter including an articulated lacerator that, when deployed, extends at an oblique angle relative to the incision catheter and is configured to move along a longitudinal incision trajectory;
- and
- an anchor stabilization and orientation catheter system with at least one anchor element configured to be positioned into a heart chamber and/or or across heart muscle to guide the incision catheter.
(canceled)
A method for performing a cardiac myotomy procedure with a catheter system, comprising:
- placing at least one anchor element in a heart;
- advancing an incision catheter of the catheter system into a left ventricle of the heart;
- deploying a lacerator of the incision catheter at an oblique angle relative to myocardium of the heart;
- providing ablative electrosurgery energy to the lacerator;
- and
- withdrawing the lacerator along a longitudinal incision trajectory to incise the myocardium.
