Abstract: A method, consisting of providing a metal wire having a wire diameter and an end, and positioning a conductor at a distance from the end of the wire. The method further includes creating an electrical discharge between the conductor and the end, while setting the distance and an electrical potential of the discharge, so as to create a bead of a predefined size on the end. The method also includes assembling the wire with the created bead into an invasive probe, so that the bead is positioned at an outer surface of the probe.

Abstract: Endovascular lead design and delivery systems are described herein. One variation of an endovascular lead apparatus may generally comprise an elongate body having a proximal portion and a distal portion, one or more electrodes positioned along a first side of the distal portion, a tray positioned along a second side of the distal portion opposite to the first side, and one or more frame members positioned along the tray and which are reconfigurable from a low-profile delivery configuration to an expanded deployed configuration, wherein expansion of the one or more frame members to the expanded deployed configuration reconfigures the distal portion into contact against a tissue wall for energy delivery via the one or more electrodes.

Abstract: The implant comprises a tubular body housing an energy harvesting module adapted to convert external stresses applied to the implant into electrical energy, and a rechargeable battery adapted to be charged by the energy harvesting module. During the storage, an external source physically separated from the implant is coupled to the implant rechargeable battery to maintain a minimum battery charge level. An interface circuit of the implant couples surface electrodes to the battery, with switching between: i) a transport and storage configuration where the electrodes are connected to the external source to receive from the latter a battery charging energy and/or to exchange communication signals with the outside through the wire link of the coupling; and ii) a functional configuration in which the surface electrodes are decoupled from the external source after the implant has been implanted. The implant further comprises a data transmitter circuit adapted, in the transport and storage configuration, to send communication signals, via the surface electrodes, on the link coupling to the external source, and/or a data receiver circuit adapted, in the transport and storage configuration, to receive, via the surface electrodes, communication signals transmitted on the link coupling to the external source.

Abstract: A medical device system has a medical device interface configured to download data from an implanted medical device. Memory stores electrode location identification rules and display definitions. Each of the display definitions correspond to possible electrode placement locations of the implanted medical device. Processing circuitry is configured to compare the downloaded data from the implanted medical device to the electrode location identification rules to identify one or more actual electrode placement locations of the possible electrode placement locations of the implanted medical device. A user output interface is in communication with the processing circuitry. The processing circuitry is configured to cause the output to display the one or more actual electrode placement locations.

Abstract: An electric stimulator for heart (as in heart pacemakers), brain (as in DBS), organs and general cells, with a supporting structure where there exists a plurality of electrically isolated electrodes called passive electrodes or field-shaping electrodes that are located under the surface of the supporting structure. The passive electrodes are controlled by an appropriate electronics control unit and powered by some electric energy storage, as a battery. Passive or field-shaping electrodes are electrically insulated, being unable to inject current in the surrounding medium, but they are capable of shaping the electric field in the space surrounding the electrodes, which has consequence on the path of the stimulating currents injected by other devices or by the organism itself. The invention also discloses locating the passive electrodes at different depths from the surface of the supporting structure.

Abstract: A catheter with a spring tip that facilitates atraumatic initial placement and also continues to protect tissue contacted by the catheter device subsequent to the initial placement. The spring tip is shock-absorbing and axially compliant and allows enhanced use of various devices in conjunction with the tip such as bioptomes, electrodes, needles, flushing catheters, delivery catheters, and the like. The atraumatic shock-absorbing tip could include conductive or non-conductive materials.

Abstract: An assembly including an autonomous capsule having an anchoring member adapted to penetrate tissue of the heart and an accessory for implantation of the capsule. The accessory includes a steerable catheter with an inner lumen, having at its distal end a tubular protection tip defining a volume for housing the capsule. The accessory also includes a disconnectable attachment mechanism for supporting and guiding the capsule to an implantation site and a sub-catheter housed within the lumen of the steerable catheter, moveable in translation and in rotation relative to the steerable catheter. The sub-catheter and the capsule are movable between a refracted position and a position wherein the capsule is deployed out of the protection tip. The sub-catheter and the capsule are provided with a first fastening mechanism for fastening the two in translation and in mutual rotation, which is disconnectable under a rotation applied to the sub-catheter.

Abstract: A wireless electrostimulation system can comprise a wireless energy transmission source, and an implantable cardiovascular wireless electrostimulation node. A receiver circuit comprising an inductive antenna can be configured to capture magnetic energy to generate a tissue electrostimulation. A tissue electrostimulation circuit, coupled to the receiver circuit, can be configured to deliver energy captured by the receiver circuit as a tissue electrostimulation waveform. Delivery of tissue electrostimulation can be initiated by a therapy control unit.
