An implantable system for treating a patient by an implantable electrical transducer and an implantable and rechargeable power source comprising a capacitive energy storage unit. A circuit is provided for recharging the power source without removing the power source from the patient. The power source preferably comprises a capacitor having a rating of at least 0.1 farads fabricated from carbonized phenol fibers.

Implantable electrical transducer powered from capacitive storage energy

A device for repositioning an organ, such as the heart, during minimally invasive surgical procedures includes a pod having a plurality of inflatable/deflatable pillows on at least an upper surface thereof, each pillow forming a separately sealed chamber. Each chamber may include a separate lumen or supply line in direct communication therewith. Each lumen is in turn connected to a fluid source through either a manually or electrically actuatable valve. The valve associated with each supply line permits fluid to be selectively introduced into or withdrawn from any number of chambers by manipulating the valves to thereby selectively inflate or deflate the selected chambers. Preferably, a pressure sensor is used to monitor the pressure in one or more chambers and means are incorporated to selectively inflate or deflate the chambers in response to the detected pressure.

Device and method for repositioning the heart during surgery

A stimulation device for screening therapeutic effects from electrical stimulation of electrically excitable tissue. The stimulation device includes inputs such that the user can easily select the polarity, amplitude, pulse width, and pulse rate of the respective stimulation signal applied on each of the implanted electrodes. Alternatively, the stimulation device automatically sets those parameters of the stimulation signal with parameters that have historically produced high ratings of therapeutic effect. The user then enters a rating of the therapeutic effect that results from the application of those stimulation signals on the implanted electrodes. The stimulation device is designed to also include a casing such that the stimulation device is adapted to be portable. Because the stimulation device of the present invention is also inexpensive, the user can carry this device around during normal daily activities of the user during the screening process. Consequently, parameters of the stimulation device that would result in optimum therapeutic effect for normal daily activities of the user can be determined more easily and more accurately.

Portable stimulation screening device for screening therapeutic effect

A tight, sterile connection between flexible tubing and a connector on a medical device is produced by pre-assembling the tubing and the connector, heat-shrinking the tubing onto the connector, and then sterilizing the connection while maintaining compression of the tubing against the connector.
