Abstract
A method is used to manufacture a surgical instrument. The surgical instrument includes a catheter and an end effector extending distally from the catheter. The method includes forming at least one electrode, sensor, or thermocouple onto the catheter or the end effector of the surgical instrument by etching or vapor depositing a three-dimensional structure onto a non-conductive material that is layered over a super elastic material.
Claims2
A surgical instrument comprising:
- (a) a handle;
- (b) a catheter extending distally from the handle, a proximal portion of the catheter defining a longitudinal axis;
- and
- (c) an end effector extending distally from the catheter, the end effector including at least at least one sensing electrode, ablating electrode, reference electrode, force sensor assembly, position sensor assembly or thermocouple that comprises:
- (i) a first layer that includes a super elastic material,
- (ii) a second layer that includes a non-conductive material that contacts the super elastic material, and
- (iii) a third layer contacting the non-conductive material.
