Abstract
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.
Claims33
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, automatic, remote, or voice-activated operation.
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 tissue, and a source of ablation therapy in communication with the handle and the distal end of the catheter,
- the improvement wherein the system has a switching mechanism to terminate therapy and one or more additional safety features to minimize the risk of inadvertent damage to tissue.
A system for preventing inadvertent damage to the heart and/or circulatory system and/or pericardial space during delivery of ablative treatment or therapy, which comprises a plurality of safety features, including (1) an immediately accessible on/off or kill switch and (2) one or more force or pressure sensors to detect and minimize excessive force delivered to the tip of an ablation catheter system.
A rapid cable connect/disconnect device for immediate separation of a male cable connector and a female cable connector, which comprises a component which grasps both connectors, maintains alignment of the connectors to one another, unlocks any locking mechanism, and separates said connectors, and is also capable of mechanically reconnecting or re-coupling the cable connectors in an aligned manner to restore continuity.
