Abstract

A catheter for injecting a thermally sensitive gelation material to remote sites within a patient'"'"'s body by maintaining the thermally sensitive gelation material in a liquid state until it is delivered to a target area within the body.

Claims

1. A method of treating a target area within the body of a patient, said method comprising the steps of:

providing an insulated catheter, said catheter adapted to deliver a reverse thermal solution within the body of the patient;

inserting the insulated catheter into the body of the patient; and

delivering the reverse thermal solution to the target area.

2. The method of claim 2 wherein the step of delivering the reverse thermal solution to the target area comprises delivering the reverse thermal solution to the heart of the patient.
