A device and means to decrease the pain associated with cancer biopsies procedures The device uses anesthetic injections and electrical currents of both positive or negative polarity, or alternating current. The device can be incorporated into existing biopsiy devices. Application on breast cancer biopsies and other types of biopsies.

Systems for treating a cardiac condition of a patient are provided. The system comprises an implantable device for delivering energy to the patient’s heart, and an external patient device configured to wirelessly communicate with the implantable device. The system can further comprise a clinician device for implanting the implantable device in the patient. The cardiac condition treated by the system can comprise atrial fibrillation. Methods of treating a cardiac condition are also provided.

The disclosure relates to an implant comprising an electronics module and an energy store, wherein the volume of the electronics module is less than 25% of the volume of the energy store.

A medical implant including an implant body for insertion into a human and/or animal body. The implant body includes at least one first and at least one second contact portion, wherein the at least one first and the at least one second contact portions contact two tissue regions performing a relative movement with respect to one another. The at least one first and the at least one second contact portions are movable relative to one another, wherein a relative movement of the contact portions may be converted into an electrical signal.

A leadless biostimulator, such as a leadless cardiac pacemaker, having a header assembly is described. The header assembly includes a helix mount mounted on a flange. An inner surface of the helix mount conforms to an outer surface of the flange, and the outer surface has a non-circular profile such that the conforming surfaces interfere with rotation of the helix mount relative to the flange. The non-circular profile includes a linear segment, such as a radial segment, that resists rotational movement of the helix mount. The helix mount has a protrusion that extends into a recess of the flange to interfere with longitudinal movement between the helix mount and the flange. The protrusion is formed before or after mounting the helix mount on the flange. The interfering surfaces threadlessly interconnect the header assembly components. Other embodiments are also described and claimed.

An implantable medical device system is configured to detect a tachyarrhythmia from a cardiac electrical signal and start an ATP therapy delay period. The implantable medical device determines whether the cardiac electrical signal received during the ATP therapy delay period satisfies ATP delivery criteria. A therapy delivery module is controlled to cancel the delayed ATP therapy if the ATP delivery criteria are not met and deliver the delayed ATP therapy if the ATP delivery criteria are met.

An implantable pulse generator includes a device housing containing pulse generator circuitry and a header molded to the device housing. The header can be formed of an epoxy header material. A header component can have a first part molded in the header material to fix the header component to the header at a surface of the header and a second part extending out of the header material.

A biostimulator, such as a leadless pacemaker, has electrode(s) coated with low-polarization coating(s). A low-polarization coating including titanium nitride can be disposed on an anode, and a low-polarization coating including a first layer of titanium nitride and a second layer of platinum black can be disposed on a cathode. The anode can be an attachment feature used to transmit torque to the biostimulator. The cathode can be a fixation element used to affix the biostimulator to a target tissue. The low-polarization coating(s) impart low-polarization to the electrode(s) to enable an atrial evoked response to be detected and used to effect automatic output regulation of the biostimulator. Other embodiments are also described and claimed.

The present invention changes the magnet-mode of an active implantable medical device (AIMD) using a static strip magnet comprising at least a first, second and third magnet. The electronic circuits of the AIMD have been programmed to register when the static strip magnet has been swiped across the AIMD so that when the magnetic field-detection sensor detects a defined north and south polarity sequence of the first, second and third magnets, the electronic circuits have been programmed to enter into magnet-mode with electrical stimulation therapy of the body tissue and/or electrical sensing of biological signals from the body tissue being suspended, maintained in a preset mode, or placed in a programmed mode.

A ventricularly implantable medical device that includes a sensing module that is configured to detect an artifact during ventricular filling and to identify an atrial event based at least on part on the detected artifact. Control circuitry of the implantable medical device is configured to deliver a ventricular pacing therapy to a patient's heart, wherein the ventricular pacing therapy is time dependent, at least in part, on the identified atrial event.
