GEL DELIVERY CATHETERS, SYSTEMS, AND METHODS

摘要

An injection catheter system is disclosed. The system includes a catheter defining a first pressure transfer lumen adapted to retain a pressure transfer material, an actuator at a proximal end of the catheter adapted to deliver a pressure from a proximal end to a distal end of the first pressure transfer lumen via the pressure transfer material, a distal section defining at least a first internal chamber adapted to retain a therapeutic gel component, at least a first plunger retained in the first internal chamber, and an injection port for delivering a therapeutic gel component into a treatment location from the first internal chamber when the actuator is used to deliver a pressure via the pressure transfer material to move the first plunger to deliver a therapeutic gel component through the injection port.
