Abstract
An ablation catheter includes a control handle and a catheter sheath removably connectable to the control handle, the catheter sheath defining a fluid lumen and having a plurality of perforations proximal the distal end of the catheter sheath. The ablation catheter further includes a shape-imparting element inserted into the fluid lumen of the catheter sheath and removably connectable to the control handle. The shape-imparting element is connectable to an RF energy source so that, in use, the shape-imparting elements act as an electrode charging fluid into the fluid lumen to be expelled through the plurality of perforations on the catheter sheath.
Claims20
An ablation catheter comprising:
- a control handle having an electrical connector arranged at a proximal end of the control handle, the electrical connector being connectable to an RF energy source;
- a catheter sheath having a proximal end and a distal end, the catheter sheath defining a fluid lumen and having one or more perforations proximal the distal end of the catheter sheath, the catheter sheath being connectable to the control handle;
- an elongate shape-imparting element of conductive material inserted into the fluid lumen of the catheter sheath and connected to the control handle at an attachment point;
- and
- an electrical conductor extending from the electrical connector to the attachment point for electrically connecting the shape-imparting element to the electrical connector and the RF energy source.
