An implantable medical device which performs the following steps during operation: a) performing a detection of whether the implantable medical device is in an implanted state; b) if it is detected that the implantable medical device is in an implanted state, activating a first diagnostic or therapeutic function of the implantable medical device, and subsequently activating a second diagnostic or therapeutic function of the implantable medical device, wherein the second diagnostic or therapeutic function is activated only after the fulfillment of at least one activation criterion selected from the group consisting of an elapse of a first time period from the activation of the first diagnostic or therapeutic function, an elapse of a second time period from the detection that the implantable medical device is in an implanted state, and a passing of a function test.

Implantable medical device

An implantable system for the diagnostic and/or therapeutic treatment of a human or animal patient contains a processor, a memory, a treatment unit and a remote data transmission unit. The system is characterized in that the memory includes a computer-readable program which prompts the processor to carry out the following steps when the program is being executed on the processor: a) ascertaining whether a treatment functionality of the treatment unit could jeopardize a patient in whom the system was implanted if a diagnostic and/or therapeutic treatment of the patient corresponding to the treatment functionality were to be carried out; b) deactivating the treatment functionality when a potential risk for the patient was ascertained; c) receiving reactivation data by way of the remote data transmission unit; and d) reactivating the deactivated treatment functionality based on the received reactivation data.

Implantable system for the diagnostic and/or therapeutic treatment of a human patient or an animal 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.

Implantable system for stimulating a human heart or an animal heart

An implantable system for stimulating a human heart or an animal heart contains a processor, a memory unit, an atrial stimulation unit, and a detection unit for detecting atrial tachycardia. The system is characterized in that the memory unit stores a computer-readable program, which prompts the processor to carry out the following steps when the program is being executed on the processor: a) detecting by way of the detection unit whether atrial tachycardia to be treated is present in a human heart or an animal heart; b) when atrial tachycardia to be treated is present, applying atrial antitachycardia pacing by way of the atrial stimulation unit; and c) after the atrial antitachycardia pacing has been applied, carrying out an atrial post-treatment stimulation, the post-treatment stimulation being configured to be within a range of 1 minute up to 7 days.

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.

An implantable system for stimulating a heart contains a processor, a memory, a stimulator, and a first detection unit for detecting a cardiac rhythm disturbance of a cardiac region. The memory includes a computer-readable program, which prompts the processor to carry out the following steps: a) detecting via the first detection unit whether a cardiac rhythm disturbance is present in a cardiac region of a heart of a patient; b) when a cardiac rhythm disturbance is present, selecting a stimulation strategy based on a selection criterion; c) stimulating the cardiac region in which the cardiac rhythm disturbance was detected by way of the stimulator, using the selected stimulation strategy; d) detecting a success and/or an efficiency of the conducted stimulation; e) comparing the success and/or the efficiency to a predefinable success and/or efficiency criterion; and f) if the predefinable success and/or efficiency criterion was not achieved, optimizing the stimulation strategy.
