Abstract
A lead sealing device that resides within the connector cavity of a pacemaker or defibrillator intended to prevent fluid intrusion by automatically sealing the lead lumen when the lead connector is inserted. The sealing mechanism may be in the form of a silicone disk located at the base of the space defined by the connector cavity in which the lead is inserted to make electrical and physical contact. It may be fixedly located at the bottom of the connector cavity, or may be a movable plug located within the connector cavity at a location other than the bottom of the cavity, such as adjacent to the connector block. In that case, the pin will make contact with the movable plug immediately after passing through the connector block, and will remain in contact with and seal the lead lumen while the pin and plug are further advanced to bring the pin into its final location to make electrical contact with the connector contact.
