Abstract
Described here are devices, systems, and methods for forming a fistula between two blood vessels. The systems may comprise a first catheter including a housing and an electrode having a proximal end and a distal end. The proximal end is fixed relative to the housing and the distal end is longitudinally slidable within the housing.
Claims26
A system for forming a fistula between two vessels comprising:
- a first catheter comprising a housing and an electrode,
- wherein the electrode comprises a proximal end, an upturned distal end, and an intermediate portion between the proximal end and the upturned distal end,
- wherein the electrode varies in width along a length defined from the proximal end to the intermediate portion,
- wherein the upturned distal end is upturned relative to a longitudinal axis of the electrode,
- wherein the proximal end of the electrode is fixed relative to the housing and the upturned distal end of the electrode is freely longitudinally slidable within the housing toward a tip of the catheter away from the proximal end;
- and
- wherein the electrode is positioned within a lumen of the housing, the lumen comprising a first diameter portion positioned proximal to an opening and a second diameter portion positioned proximal to the opening, wherein the second diameter portion comprises a smaller diameter than the first diameter portion, and the electrode is fixed to the housing at the second diameter portion.
