Abstract
Embodiments of the invention include a medical device including a handle portion, an end effector assembly, an elongate member connecting the handle portion and the end effector assembly, and one or more treatment devices extendable through the elongate member and end effector assembly. The end effector assembly includes an electrode assembly configured to cauterize tissue. The treatment devices may include an elongate cutting member with a safety tip. The treatment devices may include a multi-lumen catheter with a lumen configured to deliver fluid and another lumen configured to accommodate an injection needle, a cutting member, or other therapeutic or diagnostic devices.
Claims52
A device for performing therapy on body tissue, comprising:
- a catheter;
- an end effector assembly connected to the catheter and configured to cauterize body tissue;
- an elongate member extending through the catheter and the end effector assembly and configured to move relative to the catheter and the end effector assembly;
- and
- a safety tip on the distal end of the elongate member configured to reduce damage to body tissue.
A device for performing therapy on body tissue, comprising:
- a catheter;
- an end effector assembly connected to the catheter and configured to cauterize tissue, wherein a channel extends through the catheter and the end effector assembly;
- a needle extending through at least a portion of the channel and configured to move relative to the port;
- and
- a cutter extending through at least a portion of the channel and configured to move relative to the channel.
A device for performing therapy on body tissue, comprising:
- a catheter;
- an end effector assembly connected to the catheter and configured to cauterize tissue;
- and
- a medical device extending through the catheter and the end effector assembly and configured to move relative to the catheter and the end effector assembly,
- wherein the medical device is configured to deliver fluid, cut tissue, and cauterize tissue.
A method of performing therapy on body tissue, comprising:
- introducing a catheter into a gastrointestinal tract of a patient;
- advancing a distal end effector assembly of the catheter to tissue to be treated, the end effector assembly including an electrode assembly configured to cauterize tissue;
- and
- advancing a medical device through a lumen of the catheter, the medical device capable of delivering fluid, cutting tissue, and cauterizing tissue.
A device for performing therapy on body tissue, comprising:
- a catheter;
- an electrically conductive elongate member extending through the catheter and configured to move relative to the catheter;
- and
- a safety tip on the distal end of the elongate member configured to reduce damage to body tissue.
