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;
an injection needle housed within the central passage, the needle extendable from the central passage to provide treatment to tissue.
