ABLATION CATHETER SYSTEM WITH SAFETY FEATURES

摘要

A medical system for delivering treatment or therapy to a patient has a kill switch for interrupting the delivery. The kill switch, which can disrupt the delivery directly or can cause an error message to be generated that disrupts the delivery, can be activated by the operator or remotely. In an ablation catheter system, a kill switch mechanism immediately and abruptly terminates delivery of ablation treatment or therapy.

主权项

1. In an improved ablation catheter system comprising a longitudinally extending catheter having a proximal end and a distal end, a handle attached to the proximal end of the catheter, a mechanism at the distal end of the catheter for delivering ablation therapy to a desired location, and a generator or controller of ablation therapy in communication with the handle and the distal end of the catheter,
the improvement wherein the ablation catheter system comprises a switching mechanism which is capable of causing abrupt termination of ablation therapy by manual operation, wherein the switching mechanism is positioned between the generator or controller of ablation therapy and the catheter handle, and wherein the switching mechanism has a button or other activation means to manually terminate ablation therapy.
