Hermetically sealed cardiac pacer system and recharging system therefor |
摘要 |
An hermetically-sealed cardiac pacemaker which may be operated on a single non-rechargeable cell or a magnetic-induction-rechargeable mercury cell that is hermetically sealed along with an outgas alleviating material in a separate container within an integral stainless steel outer case, which case also houses the system electronics. The integral case is formed with an opening in which a closure plate is disposed in a recessed position and sealed about its periphery to the interior of the opening to form a receptacle in the exterior of the casing. The receptacle is filled with a biocompatible material to isolate the seal from the exterior of the casing and the case acts along with the internal electronics during recharging as a charging current regulator system which maintains a substantially constant power transfer from the charging transmitter to the internal receiver despite variations in their proximate spacing.
