摘要： A stimulation system includes an energy source, an electronics unit with a controller, and an actuator that is coupled with the electronics unit and/or the energy source. The actuator emits electromagnetic waves for stimulation of genetically manipulated tissue. The electronics unit is disposed in a housing. The stimulation system is configured for at least temporary implantation in a human or animal body. The controller controls the stimulation of tissue in the body by way of the electromagnetic waves emitted by the actuator. A selector of the stimulation system selects the area of the said tissue for stimulation. The selector includes a masking device for masking certain areas of the tissue, so that an intensity of the stimulation for the masked areas is reduced or equal to zero.

摘要： An implantable system for treating a heart contains a processor, a memory unit, a treatment unit including a treatment electrode, and a detection unit for detecting a cardiac event requiring treatment. The memory unit includes a computer-readable program, which prompts the processor to perform the following steps: a) detecting by way of the detection unit whether a cardiac event to be treated has occurred in the heart; b) if a cardiac event to be treated has occurred, determining a position of the treatment electrode or determining a variable correlating with this position; and c) comparing the position of the treatment electrode or the variable correlating with the position to a reference variable, and carrying out, or not carrying out a cardiac treatment by way of the treatment unit and the treatment electrode as a function of the position of the treatment electrode or the variable correlating with the position.

摘要： A medical electrode device for implantation comprises a carrier formed from an electrically insulating material and defining a surface extending along a plane of extension, and at least one electrode arranged on the carrier for emitting an electrical stimulation signal and/or receiving an electrical sense signal. The at least one electrode comprises first and section wall sections. Said first wall section, in a cross-section along a cross-sectional plane perpendicular to said plane of extension, extends straight along a perpendicular direction with respect to said plane of extension or at an oblique angle with respect to said perpendicular direction, the first wall section in contact with the carrier electrically insulating material. Said second wall section, in said cross-section along said cross-sectional plane perpendicular to said plane of extension, adjoins said first wall section and is curved, the second wall section not in contact with the carrier electrically insulating material.

摘要： A method programs an implantable medical device to configure the implantable medical device for stimulating neural tissue by at least one electrode. The method includes: performing, by the implantable medical device, an evoked compound action potential (eCAP) threshold search by stimulating the neural tissue with test stimulation pulses; determining, based on the eCAP threshold search, an eCAP threshold amplitude and a coupling factor that is indicative of a coupling between the at least one electrode and the neural tissue; and generating a first set of stimulation parameters containing at least a stimulation amplitude that is determined in dependence on the eCAP threshold amplitude and the coupling factor.

摘要： A catheter device for repositioning or explanting an implantable medical device comprises an outer catheter, and a steerable catheter extending through the outer catheter, wherein the outer catheter is axially movable with respect to the steerable catheter. A snare catheter extends through the steerable catheter, wherein the snare catheter is axially movable relative to the steerable catheter. A mandrel may extend through the snare catheter and comprising a distal end, wherein the mandrel is axially movable relative to the snare catheter. A snare may be arranged on the distal end of the mandrel for establishing a connection to the implantable medical device, wherein the snare, by moving the mandrel with respect to the snare catheter, is at least partially retractable into the snare catheter.
