Abstract
One aspect of the present disclosure includes a sheath configured to receive an ablation probe. The sheath includes a temperature-controlled anchor element thereon configured to attach the sheath to bodily tissue.
Claims20
A sheath for receiving an ablation probe, the sheath comprising:
- a sheath body comprising:
- a first outer wall surface and a first inner wall surface, wherein the first outer wall surface and the first inner wall surface extend between a proximal end and a distal end of the sheath body;
- one or more peripheral lumens located between the first outer wall surface and the first inner wall surface, wherein the one or more peripheral lumens extend between the proximal end and distal end of the sheath body;
- and
- a central lumen that extends between the proximal end and the distal end of the sheath body and is defined by the first inner wall surface;
- and
- a temperature-controlled anchor element operably coupled to the distal end of the sheath body, the anchor element comprising a proximal end, a distal end, a second outer wall surface and a second inner wall surface extending between the proximal and distal ends of the anchor element, and a second central lumen extending between the proximal and distal ends of the anchor element, wherein the second central lumen is defined by the second inner wall surface and is in fluid communication with the first central lumen.

A method for ablating a target bodily tissue, the method comprising:
- delivering a sheath to a target bodily tissue, wherein the sheath comprises a sheath body comprising a first central lumen and a temperature-controlled anchor element comprising a second central lumen that is in fluid communication with the first central lumen;
- cooling the anchor element to a temperature sufficient to attach the sheath to the target bodily tissue;
- and
- activating a radio frequency (RF) ablation probe, being housed within the first and second central lumens of the sheath, to ablate the target bodily tissue.
