Abstract
Described herein are devices and methods for performing ablation using ablation catheters with one or more patterned and textured active areas. An ablation catheter includes a proximal section, a distal section, and a sheath coupled between the distal section and the proximal section. The distal section includes an active area with a patterned, textured surface that is configured to apply radiofrequency (RF) energy, cryogenic cooling, or laser energy output to a portion of target tissue, such that the portion of target tissue is ablated. The patterned, textured surface of the active area is configured to maintain contact between the target tissue and the active area.
Claims20
An ablation catheter comprising:
- a proximal section;
- a distal section comprising:
- an active area, wherein a surface of the active area comprises a patterned texture and is configured to apply radiofrequency (RF) energy, cryogenic cooling, or laser energy output to a portion of a target tissue, such that the portion of the target tissue is ablated;
- and
- a plurality of view ports surrounded by the patterned texture, the plurality of view ports being configured to send and receive optical signals to and from the target tissue;
- and
- a sheath coupled between the proximal section and the distal section, wherein the patterned texture is configured to increase a friction coefficient of contact between the target tissue and the active area, maintain contact between the target tissue and the active area, and prevent movement of the target tissue relative to the active area during a time of an ablation procedure.
A method for performing tissue ablation, the method comprising:
- providing an ablation catheter for the tissue ablation, wherein the ablation catheter comprises a distal end with one or more active areas, wherein at least one active area comprises a patterned, textured surface and a plurality of view ports surrounded by the patterned, textured surface;
- ablating a portion of a target tissue using radiofrequency (RF) energy, cryogenic cooling, or laser energy output from the patterned, textured surface of the at least one active area;
- using the patterned, textured surface to increase a friction coefficient of contact between the portion of the target tissue and the at least one active area, facilitate steady contact between the at least one active area and the portion of the target tissue, and prevent movement of the target tissue relative to the at least one active area;
- and
- using the plurality of view ports arranged on the patterned, textured surface to send and receive optical signals to and from the target tissue.
A catheter for performing tissue ablation in a patient, the catheter comprising:
- a proximal section;
- a distal section comprising:
- an active area comprising a plurality of patterned, textured surfaces, wherein the active area is configured to apply radiofrequency (RF) energy, cryogenic cooling, or laser energy output to a portion of a target tissue, such that the portion of the target tissue is ablated, wherein the active area further comprises a plurality of view ports surrounded by the plurality of patterned, textured surfaces, the plurality of view ports being configured to send and receive optical signals to and from the target tissue;
- and
- a sheath coupled between the proximal section and the distal section, wherein the plurality of patterned, textured surfaces of the active area is configured to increase a friction coefficient of contact between the target tissue and the active area, maintain contact between the target tissue and the active area, and prevent movement of the target tissue relative to the active area during a time of an ablation procedure.
