The invention relates to an implantable capsule, particularly an autonomous capsule of cardiac stimulation, including a tubular body provided at the distal end of an anchoring element with a helical screw adapted to penetrate tissue a wall of an organ of a patient, the body housing a set of functional elements of the capsule. It includes, in an annular area surrounding the base of the screw recessed arrangements defining a set of flush tips oriented in a circumferential direction opposite to that of the screwing, to avoid the unscrewing of the capsule.

A lead for cardiac conduction system includes a proximal end, a lead body extending from the proximal end, and a distal end extending from the lead body. The lead body includes a non-conductive spacer. The distal end includes a helix electrode distal to the spacer. The lead further includes a ring electrode proximal to the spacer and surrounding a portion of the lead body. The helix electrode includes a core disposed within a helical space of the helix electrode. Another lead for cardiac conduction system includes a proximal end, a lead body extending from the proximal end, and a distal end extending from the lead body. The distal end includes a first helix electrode extending from the lead body and a second helix electrode extending from the lead body. A tip of the first helix electrode is distal to a tip of the second helix electrode.

An anchorage device is provided that is configured to surround an implantable medical device. The anchorage device includes a substrate and a hemostatic agent. The substrate includes a first piece and a second piece that is joined with the first piece. The first piece includes the hemostatic agent and the second piece includes an active pharmaceutical ingredient. Kits, systems and methods are disclosed.

A biostimulator system includes a biostimulator coupled to a biostimulator transport system. The biostimulator includes a header assembly. The header assembly includes a flange having a central axis. A fixation element mount is mounted on the flange. The fixation element mount includes a mounting ring on an insulator base. The mounting ring extends around the central axis within a groove of the insulator base. A fixation element is coupled to the mounting ring. Other embodiments are also described and claimed.

A catheter system for implanting a lead for cardiac conduction system is provided. The catheter system includes a catheter having an orifice extending from a distal end of the catheter to a proximal end of the catheter for implanting the lead, and a probe extending through the catheter. The probe includes a conductive wire covered with an insulation layer. A distal end of the wire is exposed from the insulation layer. The distal end of the wire includes a wire electrode configured to conduct pacing prior to implanting the lead.

A system for delivering treatment to a biological subject, the system including: at least one substrate including a plurality of microstructures configured to breach a stratum corneum of the subject; at least one sensor operatively connected to at least one microstructure, the at least one sensor being configured to measure response signals from the at least one microstructure; at least one treatment delivery mechanism operatively coupled to at least one microstructure to deliver treatment via at least one microstructure; and, one or more electronic processing devices that are configured to control the at least one treatment delivery mechanism to thereby deliver treatment to the subject at least partially in accordance with the measured response signals.

In some examples, an implantable medical device includes a device body extending from a proximal portion to a distal portion along a longitudinal axis, a fixation component, and an electrode interface assembly. The fixation component includes a penetrator tine extending away from the distal portion of the device body and configured to penetrate a tissue. The electrode interface assembly includes a leadlet extending away from the distal portion of the device body, an elongated body extending away from the distal portion of the device body the elongated body defining a recess and a groove, wherein the groove is configured to receive the leadlet, and an electrode extending from the elongated body and disposed within the recess.
