ABLATION CATHETER

摘要

An ablation catheter including a handle, a tubular irrigation member defining a fluid lumen and having a plurality of perforations proximal the distal end of the tubular irrigation member. At least one ablation electrode is arranged at the distal end of an elongate tubular sheath inserted into the lumen of the tubular irrigation member, the elongate tubular sheath being axially displaceable within the lumen of the tubular irrigation member. The ablation catheter may also include two ablation electrodes each attached to an elongate tubuar sheath which are telescopically arranged within the tubular irrigation member. The ablation electrodes may be displaceable simultaneously together or individually.

1. An ablation catheter which includes:
a tubular irrigation member of a non-conductive material having a proximal end and a distal end, the tubular member defining a fluid lumen and having one or more perforations at or proximal the distal end of the tubular member; an elongate tubular sheath having a lumen extending from a proximal end of the tubular sheath to a distal end of the tubular sheath, and one or more ablation electrodes arranged at, or adjacent, the distal end, the elongate tubular member being removably received into the fluid lumen of the irrigation member and the proximal end of the elongate tubular sheath connected to a control handle, wherein the elongate tubular sheath is axially displaceable within the fluid lumen of the irrigation member.
