Abstract
A catheter and a method of advancing the catheter within a human vessel are provided. The catheter has a shaft that has a distal end and a proximal end, a hub provided at the proximal end, and a first piezoelectric element provided at the hub. A second piezoelectric element is provided at a location on the shaft that is distal to the hub, and a conductive wire connects the first piezoelectric element and the second piezoelectric element. Electrical energy is applied from the first piezoelectric element towards the second piezoelectric element to cause the distal end of the shaft to move.
Claims4
A method of advancing a catheter within a human vessel, comprising:
- providing a catheter having:
- a shaft that has a distal end and a proximal end;
- a hub provided at the proximal end, with a first piezoelectric element provided at the hub;
- a second piezoelectric element provided at a location on the shaft that is distal to the hub;
- and
- a conductive wire connecting the first piezoelectric element and the second piezoelectric element;
- and
- applying electrical energy from the first piezoelectric element towards the second piezoelectric element to cause the distal end of the shaft to move.
