Fluid-assisted medical devices, systems and methods
First Claim
1. A medical device comprising:
- a catheter tube having a distal end and a lumen, the tube configured to assist in applying tamponage to a bleeding source in a gastrointestinal tract when flexed;
a catheter tip assembled with the tube adjacent the distal end of the tube, the catheter tip having a catheter tip outer surface and including;
a probe body comprising an electrically insulative material;
at least one electrode pair, the electrode pair comprising a first electrode spaced from a second electrode, the first electrode and the second electrode located on the probe body;
a fluid distribution manifold to direct a fluid from inside the probe body towards the tip outer surface, the manifold comprises a central passage within the probe body and a plurality of lateral passages which extend from the central passage towards the tip outer surface, the central passage narrowed at a distal end thereof; and
an injection needle housed within the central passage, the needle extendable from the central passage to provide treatment to tissue.

Abstract
A medical device is provided which comprises a catheter tube having a distal end and a lumen, and configured to assist in applying tamponage to a bleeding source in a gastrointestinal tract when flexed. A catheter tip having a catheter tip outer surface is assembled with the tube adjacent the distal end of the tube. The catheter tip comprises a probe body comprising an electrically insulative material, at least one electrode pair located on the probe body which comprises a first electrode spaced from a second electrode, and a fluid distribution manifold to direct a fluid from inside the probe body towards the tip outer surface. The manifold comprises a central passage within the probe body and a plurality of lateral passages which extend from the central passage towards the tip outer surface. An extendable injection needle is housed within the central passage to provide treatment to tissue.
