A system includes a medical device comprising a reader and a processor, and a storage medium containing a content. The reader is configured to read the content from the storage medium such that the processor switches the medical device from a first mode to a second mode based on the content. The processor or the reader is configured to interface with the storage medium based on the processor switching the medical device from the first mode to the second mode such that the content of the storage medium is deleted or scrambled. Once the content in the storage medium is erased or scrambled, it is no longer usable by the medical device until additional content has been loaded or programmed into the storage medium.

Computer implemented methods and systems are provided for automatically determining capture thresholds for an implantable medical device equipped for cardiac stimulus pacing using a multi-pole left ventricular (LV) lead. The methods and systems measures a base capture threshold for a base pacing vector utilizing stimulation pulses varied over at least a portion of an outer test range. The base pacing vector is defined by a first LV electrode provided on the LV lead and a second electrode located remote from an LV chamber. The methods and systems designate a secondary pacing vector that includes the first LV electrode and a neighbor LV electrode provided on the LV lead. The methods and systems further define an inner test range having secondary limits based on the base capture threshold, wherein at least one of the limits for the inner test range differs from a corresponding limit for the outer test range. The methods and systems measure a secondary capture threshold associated with the secondary pacing vector utilizing stimulation pulses varied over at least a portion of the inner test range.

An improved external trial stimulator provides neurostimulation functionality for implanted medical electrodes prior to implantation of an implantable neurostimulator. The external trial stimulator is housed in a four-part housing that provides mechanical and electrostatic discharge protection for the electronics mounted in a central frame of the housing. Connectors attached to leads from the electrodes connect to contacts that are recessed in the housing through ports that are centered for easy access. Multiple indicators provide information to users of the external trial stimulator.

Electrical stimulation systems and methods for operation of the electrical stimulation system are described. The method includes directing electrical stimulation through the electrodes of the lead and monitoring movements of a hand positioned over an implantation site of an implantable control module of the electrical stimulation system using an accelerometer coupled to a processor of the implantable control module. Another method includes detecting, by a sensor, a plurality of taps of a body region of a patient over an implantation site of the implantable control module, identifying, by the processor of the implantable control module, an indicator, trigger, or marker based on the detected tapping, and performing an activity corresponding to the identified indicator, trigger, or marker.

A muscle injury prevention and muscle strengthening system has an electrode harness, a controller, electrical muscle stimulation (EMS) electrodes, and an environmental sensor. The electrode harness secures around the patient's body holding the EMS electrodes in contact with the patient's body. The EMS electrodes send targeted electrical pulses at the motor nerves of the patient. The environmental sensor observes responses from the patient while monitoring external environmental factors. The environmental sensors range from EMG sensors to location sensors to gather important information about the patient and the environment. The controller manages the operation of the electrical components of the present invention. The present invention is fastened securely to the patient throughout all exercises and activities to properly stimulate the patient and gather responses from the patient.

An implantable system stimulates a human or animal heart. The system contains a processor, a memory unit, an atrial stimulation unit, a ventricular stimulation unit, and a detection unit for detecting atrial tachycardia. The memory unit stores a computer-readable program that prompts the processor to: a) detect by the detection unit whether atrial tachycardia to be treated is present in the heart; b) when atrial tachycardia to be treated is present, carrying out a ventricular conditioning stimulation by way of the ventricular stimulation unit; and c) applying atrial antitachycardia pacing in the form of a stimulation pulse sequence of 2 to 20 pulses or a high-frequency burst having a frequency of up to 50 Hz and a duration of up to 60 seconds by way of the atrial stimulation unit as the ventricular conditioning stimulation is being carried out and/or thereafter.

A process for creating an anode foil for use in an electrolytic capacitor of an implantable cardioverter defibrillator is provided. The process includes placing a partially masked bulk metal foil in an etch electrolyte solution to etch exposed area of the bulk metal foil, removing the etch-resistant mask to expose the unetched areas, widening the bulk metal foil, and partially cutting the bulk metal foil between a plurality of unetched areas to form a partially detached etched foil anode, such that the unetched areas are not cut and the unetched areas serve as attachment tabs to keep the partially detached etched foil anode attached to the bulk metal foil. Additionally, the process may include an oxide formation step, wherein the step of partially cutting the bulk metal foil is performed after the etching and widening steps, and before the oxide formation step.
