A lead device is provided for a medical treatment apparatus, where the lead device includes protruding anchoring mechanisms for anchoring the lead device in tissue. The anchoring mechanism include permanent anchoring mechanisms, or a combination of permanent and dissolvable anchoring mechanisms, to anchor the device in tissue. The anchoring mechanism resists migration of the lead device in at least one or both axial directions.

In some examples, controlling delivery of therapy includes using an implantable medical device comprising at least one electrode. Processing circuitry of a system comprising the device may receive, from an application running on a patient personal device, a patient request entered by the patient into the application. The processing circuitry may further determine, based on the patient request, a requested value of a therapy parameter, compare the requested value to information stored in a memory of the medical device system, the information indicating one or more allowable values of the therapy parameter, determine that the requested value is one of the allowable values based on the comparison of the requested value of the therapy parameter to the one or more allowable values, and control the implantable medical device to deliver cardiac pacing via the at least one electrode according to the requested value for a period of time.

Systems and methods for His bundle pacing and classifying response to pacing impulses include applying, using a pulse generator, an impulse through a stimulating electrode to induce a response from a patient heart. A response to the impulse is measured using at least one sensing electrode and time-domain based characteristics of the response are analyzed to determine whether His bundle capture has occurred and, if so, what type of capture has occurred.

The invention relates to improvements in the technical field of electromedical electrodes. For this purpose, an electromedical electrode is proposed, which comprises, on the distal end thereof, at least one anchoring means which is made of printed circuit board material.
