Abstract
A catheter for the treatment of tissue, particularly for the treatment of cardiac tissue to alleviate cardiac arrhythmias includes a connector having mechanical use limiter that may be placed in the handle of the catheter or at any point along the electrical connection pathway to an electro-anatomic mapping system and/or ablation system. The mechanical use limiter has a counter wheel and locking pin which when engaged disables the reconnection of the connector to any mated connector after a predetermined number of uses.
Claims17
A connector for establishing a mechanical and electrical connection between a medical probe and a system wherein the connector is adapted to connect to a mated connector and includes a mechanical limiter comprising:
- a counter pin movably attached within the connector wherein the counter pin moves when the connector is mated to any mated connector;
- a first rotatable gear having a notch rotated each time the counter pin is moved upon mating the connector to any mated connector;
- a limiter pin which is biased against the rotatable gear until the notch and limiter pin are aligned wherein the limiter pin moves into a locking position in the connector to block reconnection of the connector to any mated connector thereby blocking connection of the probe to the system.
An electrophysiology catheter having a handle and at least one electrode for use with an electrophysiology mapping and ablation system comprising:
- a connector for connecting the catheter to the system designed to mate with a mated connector in communication with the system wherein the connector includes a mechanical limiter comprising:
- a counter pin movably attached within the connector wherein the counter pin moves when the connector is mated to any mated connector portion;
- a first rotatable gear having a notch rotated each time the counter pin is moved upon mating the connector to any mated connector;
- a limiter pin which is biased against the rotatable gear until the notch and limiter pin are aligned wherein the limiter pin moves into a locking position in the connector to block reconnection of the connector to any mated connector portion thereby blocking connection of the catheter to the system.
An electrophysiology catheter having a handle and at least one electrode for use with an electrophysiology mapping and ablation system comprising a connector for connecting the catheter to the system designed to mate with a mated connector in communication with the system wherein the connector includes a mechanical limiter capable of blocking reconnection of the connector to any mated connector portion thereby blocking connection of the catheter to the system after a predetermined number of uses.
