Abstract
A catheter includes a catheter body; at least one shock wave emitter disposed on the catheter body; and a moveable shield extending at least partially around the catheter body and configured for translating along the catheter body. Exemplary catheters are configured to modify lesions, including fibrotic and calcified tissue buildup within the body.
Claims31
A catheter comprising:
- a catheter body;
- at least one shock wave emitter disposed on the catheter body;
- and
- a moveable shield extending at least partially around the catheter body and configured for translating along the catheter body.
1 more element
A catheter for use in a body lumen, the catheter comprising:
- a catheter body comprising a central lumen;
- at least one shock wave emitter disposed at a distal portion of the catheter body and configured to generate at least one shock wave that propagates distally of the catheter body;
- and
- a cutter configured to be translated relative to the catheter body to an extended position in which a distal end of the cutter is distal of a distal end of the catheter body for cutting tissue located distally of the distal end of the catheter body.
1 more element
A catheter comprising:
- a catheter body comprising a cavity at a distal end of the catheter body and a central lumen configured to receive at least one of a guidewire and a pacemaker lead, wherein the central lumen has a smaller diameter than the cavity at the distal end of the catheter body;
- and
- at least one shock wave emitter positioned outwardly of the cavity and configured to generate at least one shock wave that propagates into the cavity at the distal end of the catheter body to treat target material disposed within the cavity and/or at a distal end of the cavity.
