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.

A leadless biostimulator has a housing including an electronics compartment, an electronics assembly mounted in the electronics compartment, a proximal electrode that disposed on and/or integrated into the housing, and an electrical feedthrough assembly. The electrical feedthrough assembly includes a distal electrode and a flange. The flange is mounted on the housing. The distal electrode is electrically isolated from the flange by an insulator and configured to be placed in contact with target tissue to which a pacing impulse is to be transmitted by the leadless biostimulator. A mount is mounted on the flange and thereby mounted on the electrical feedthrough assembly. A fixation element is mounted on the mount and configured to facilitate fixation of the leadless biostimulator to tissue of a patient.

The present invention relates generally to the manufacture of conductive scaffolds of micro and/or nanofibers with the help of different printing techniques (e.g., near-field electrostatic printing, inkjet printing), such scaffolds enabling the formation of two-dimensional (2D) or three-dimensional (3D) neural networks to mimic the native counterparts. Applications of such patterned conductive scaffolds include, but are not limited to, an engineered conduit for guiding the differentiation and outgrowth of neural cells in peripheral nerve damage or in large-volume spinal cord injury under the electrical stimulation. Meanwhile, the scaffolds could also locally deliver various biomolecules in conjunction with electrical stimulation for facilitated nervous system regeneration (FIG. 1).

Techniques are disclosed for treating arrhythmias using an implantable medical device. An implantable medical device that is adapted for implantation wholly within a heart chamber of the heart of a patient may include a reservoir containing one or more therapeutically useful doses of a drug for treating an arrhythmia. The implantable medical device may include processing circuitry configured to detect an occurrence of the arrhythmia in the heart of the patient. The implantable medical device may include a valve operable to be opened in response to detecting the occurrence of the arrhythmia in the heart of the patient to release a therapeutically useful dose of the drug into the heart of the patient to treat arrhythmia of the heart.

The disclosure features surface coatings formed from dimeric steroid prodrugs for the extended delivery of a drug from a surface, and for the treatment of a disease or condition. Also provided herein are drug depots formed from dimeric steroid prodrugs for the extended delivery of a drug for use in combination with implantable medical devices. Said dimeric steroid prodrugs are represented by the formula D1-L-D2, wherein D1 and D2 are independently a steroid radical and L is a linker covalently linking D1 to D2.

A leadless biostimulator, and an electrical feedthrough assembly for use therewith, are described herein. The leadless biostimulator comprises an electrode body including a cup having an electrode wall extending distally from an electrode base around an electrode cavity, an electrode tip mounted on a distal end of the electrode body, and a filler in the electrode cavity between the electrode base and the electrode tip, wherein the filler includes a therapeutic agent. The electrode tip is configured to be placed in contact with target tissue to which a pacing impulse is to be transmitted by the leadless biostimulator. A pin extends proximally from the electrode base, wherein the pin is configured to be into contact with an electrical connector of an electronics assembly within a housing of the leadless biostimulator, and wherein the electrical feedthrough assembly is configured to be mounted on the housing of the leadless biostimulator.

A system for selecting a sensitivity level for adjusting an intensity setting for therapy provided to a patient includes one or more processors and one or more processors coupled to the memory. The one or more processors are configured to receive an indication of an input to adjust an intensity setting related to the therapy provided to the patient and determine a sensitivity level for adjustment of the intensity setting based on an efficacy of the therapy provided to the patient. The one or more processors are further configured to determine an updated intensity level for the intensity setting based on the sensitivity level and the input to adjust the intensity setting and output an instruction to cause a medical device to provide the therapy at the updated intensity level.

The present invention relates to methods of treating or preventing addiction and relapse use of addictive agents where the method comprises: (a) administering to a subject a co-therapy treatment with an auricular or peri-auricular electro-acupuncture or neurostimulation device, (b) co-treatment with at least one non-narcotic detoxification agent and (c) administering to the subject an opioid antagonist. The methods and compositions of the invention are useful in the treatment or prevention of addiction to any agent, including alcohol, nicotine, marijuana, cocaine, and amphetamines, as well as compulsive and addictive behaviors, including pathological gambling and pathological overeating.

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.
