According to an embodiment, a medical device is disclosed. The medical device includes an external unit and an implantable unit. The external unit includes an electronic unit operationally coupled to a transmitter coil that is configured transmit power and/or data signal over a wireless transcutaneous link, a coil unit comprising a loop structure with the transmitter coil being wound around and along at least a part of length of the loop structure, and a fixation unit configured to attach the loop structure to a user's body i) proximal to an implantable receiver coil that is configured to be implanted within a body part, and ii) around a body part of a user such that a part of the body part is positioned in a hollow section of the loop structure. The implantable unit includes the implantable receiver coil configured to receive the power and/or data signal over the wireless transcutaneous link, a processing unit configured to i) process the received data signal to control functionalities of at least one of the components of the implantable unit, and/or ii) utilize the received power for operation of at least one of the components of the implantable unit. The wireless transcutaneous link includes a coupling between the transmitter coil and the receiver coil, and when the loop structure is attached using the fixation unit, at least a substantial number of magnetic field lines generated in response to excitation of the transmitter coil passes through the implantable receiver coil.

Pacemakers and pacemaker delivery systems and methods are disclosed which use a modified cylindrical pacemaker body having a flat side which includes the anode/cathode and spikes to anchor the pacemaker in place within the pericardium.

In an implantable hybrid lead and a method of manufacturing the implantable hybrid lead, the implantable hybrid lead includes a conduit, a line electrode and a plurality of electrode terminals. The conduit has a fine channel through which a medicine is injected. The line electrode is inserted to and is combined with an outside of the conduit, and applies electrical simulation to a selected portion of a living body. A plurality of electrode terminals is disposed at an end of the conduit by a predetermined distance.

The present invention relates to materials having therapeutic compositions releasably contained within the materials. The materials are configured to release therapeutic compositions at a desired rate. The present invention also relates to devices incorporating the materials.

An implantable drug eluting medical device includes a polymer substrate having a surface, a first plurality of nanofibers, and at least one antimicrobial drug. Each of the first plurality of nanofibers includes a first portion interpenetrated with the surface of the substrate to mechanically fix the nanofiber to the substrate, and a second portion projecting from the surface. The at least one antimicrobial drug is disposed within or among the second portion of the first plurality of nanofibers.

A device for producing a trabecular fiber within a ventricle of a heart. The device includes a substrate and a first tissue anchor connected to the substrate. The substrate is formed of a non-rigid material.

Methods of treating acute heart failure in a patient in need thereof. Methods include inserting a therapy delivery device into a pulmonary artery of the patient and applying a therapy signal to autonomic cardiopulmonary fibers surrounding the pulmonary artery. The therapy signal affects heart contractility more than heart rate. Specifically, the application of the therapy signal increases heart contractility and treats the acute heart failure in the patient. The therapy signal can include electrical or chemical modulation.

A leadless biostimulator includes a housing, and distal and proximal electrodes disposed on or integrated into the housing. The distal electrode includes an electrode body and an electrode tip mounted on a distal end of the electrode body, wherein the electrode tip is electrically conductive and configured to be placed in contact with a stimulation site. The electrode tip includes a distal tip end facing a surrounding environment and opposite a proximal tip end. The electrode tip defines a tip hole extending through the electrode tip along a longitudinal axis of the housing from the distal tip end to the proximal tip end. The tip hole comprises a through hole having a first diameter at the distal tip end and a second diameter at the proximal tip end of the tip electrode, wherein the first diameter of the tip hole is less than the second diameter of the tip hole.

Systems, apparatus, methods and computer-readable storage media that facilitate monitoring the integrity of telemetry connectivity between an implantable device and an external device are provided. In one embodiment, an implantable device includes a monitoring component that monitors advertisement signal information identifying an amount of advertisement signals transmitted to the external device within a defined time period, and telemetry session information identifying an amount of the telemetry sessions that are established between the external device and the implantable device within the defined time period. A connectivity assessment component of the implantable device further determines whether a telemetry connectivity problem exists between the external device and the implantable device based on a degree of miscorrelation between the advertisement signal information and the telemetry session information.

Methods of treating acute heart failure in a patient in need thereof. Methods include inserting a therapy delivery device into a pulmonary artery of the patient and applying a therapy signal to autonomic cardiopulmonary fibers surrounding the pulmonary artery. The therapy signal affects heart contractility more than heart rate. Specifically, the application of the therapy signal increases heart contractility and treats the acute heart failure in the patient. The therapy signal can include electrical or chemical modulation.
