Abstract
A catheter based delivery system may be used for both therapeutic and diagnostic applications. The catheter based delivery system includes a catheter having a distal end. The distal end of the catheter includes several electrodes that can emit a radio frequency waveform, and may receive a signal representative of an impedance of material in the exposed to the radio frequency waveform. The radio frequency waveform may also be applied to ablate specifically targeted material exposed to the radio frequency waveform. The several electrodes may be configured as an antenna.
Claims16
A catheter based delivery system comprising:
- a catheter having a distal tip;
- and
- a plurality of electrodes disposed in said distal tip, wherein said electrodes are selectively operable to provide an RF waveform to generate an image of an area adjacent to said distal tip.
A catheter based deliver system comprising:
- a catheter having a distal tip;
- and
- a plurality of electrodes disposed in said distal tip, said electrodes being selectively operable to provide and RF waveform to ablate selected biological material adjacent to said distal tip.
A catheter based delivery system comprising:
- a catheter having a distal end;
- an emitter electrode disposed in said distal end;
- at least one director electrode disposed in said distal end;
- at least one reflector electrode disposed in said distal end.
A catheter based delivery system comprising:
- a catheter having a distal end;
- an antenna capable of transmitting RF energy disposed at said distal end.
