Abstract
A medical device is provided and includes a thermal ablation catheter and a deployable cage assembly for use in thermal ablation therapy. The deployable cage assembly includes a plurality of arms, each of which has a pair of opposed ends attached to the thermal ablation catheter. Each of the arms is movable from a relaxed configuration to a deployed configuration. When relaxed, the arms are substantially proximate to the thermal ablation catheter. When deployed, the arms cooperate with each other to form an open structure which extends radially outward from the thermal ablation catheter. The thermal ablation device also includes a distensible bladder that serves as an endocervical seal.
Claims21
A medical device for use in thermal ablation therapy, comprising a thermal ablation catheter;
- and a deployable cage assembly having a plurality of arms, each of which includes a pair of opposed ends attached to said thermal ablation catheter, each of said arms being movable from a relaxed configuration, in which it is substantially proximate to said thermal ablation catheter, to a deployed configuration, in which it cooperates with the other of said arms to form an open structure which extends outward from said thermal ablation catheter.
A medical device for use in thermal ablation therapy, comprising a thermal ablation catheter having a fluid stem and a plurality of fluid ports in communication with said fluid stem;
- and a deployable cage assembly having a plurality of arms, each of said arms being movable from a relaxed configuration, in which it is substantially proximate to said thermal ablation catheter, to a deployed configuration, in which it cooperates with the other of said arms to form an open structure which extends outward from said thermal ablation catheter, said open structure surrounding said fluid ports.
A method for performing thermal ablation therapy using a medical device which includes a thermal ablation catheter and a deployable cage assembly attached to a distal end of said thermal ablation catheter, said method comprising the steps of:
- (a) inserting said distal end of said thermal ablation catheter into a cavity;
- (b) deploying said cage assembly such that said cage assembly forms an open structure which extends outward from said thermal ablation catheter;
- (c) supplying a fluid to the cavity through said thermal ablation catheter;
- and
- (d) conductively heating the fluid within the cavity to a desired temperature and maintaining the temperature for a desired time period.
