Disclosed herein is an implantable medical device including an antimicrobial layer. The antimicrobial layer may include a first distinct size of silver nanoparticles, a second distinct size of silver nanoparticles, and a third distinct size of silver nanoparticles. The antimicrobial layer extends over a surface of the implantable medical device, and, in some instances, the surface of the implantable medical device may serve as a substrate on which the antimicrobial layer is deposited.

A leadless intra-cardiac medical device (LIMD) includes a housing configured to be implanted entirely within a single local chamber of the heart.

Single chamber leadless intra-cardiac medical device with dual-chamber functionality

An implantable cardiac stimulation and rhythm management device includes an impedance measuring circuit which determines a patient's intra-thoracic impedance and the resistance and reactance components of the impedance. The device includes a microcontroller which calculates a ratio (Z/R) which equals the reactance (Z) divided by the resistance (R). The microcontroller is configured to use the calculated ratios to establish a baseline intra-thoracic fluid level, an upper bound relative to the baseline, and a lower bound relative to the baseline, and to monitor the Z/R ratio relative to the baseline and upper and lower bounds. When the Z/R ratios are outside of the established bounds, operating parameters of the stimulation and rhythm management may be altered by the microcontroller.

Apparatus and method for two-component bioelectrical impedance ratio measuring and monitoring

Implantable medical devices, such as pacemakers or implantable cardioverter defibrillators (ICDs), are vulnerable to the powerful magnetic fields associated with magnetic resonance imaging (MRI). In particular, pulsed gradient components, if strong enough, can induce parasitic currents that may damage the device or cause parasitic pacing that may trigger an arrhythmia in the patient. The static magnetic field components of the MRI typically do not induce parasitic currents, even though they may be as strong as the pulsed gradient components. Accordingly, techniques are described herein for specifically addressing the pulsed gradient components of the MRI fields so as to reduce the risk of parasitic currents. In one example, a pacemaker switches to tri-state pacing outputs in the presence of strong pulsed gradient magnetic fields. The device continues with normal bi-state pacing outputs so long as the pulsed gradient fields are not strong, even in the presence of a strong static magnetic field. As an added safety feature, the pacemaker switches to fixed-rate ventricular pacing whenever strong static MRI fields are detected.

System and method for responding to pulsed gradient magnetic fields using an implantable medical device

An implementation of a technology, described herein, for implantable medical therapy devices and techniques related to notifications related to the use of such devices. One implementation, described herein, provides a notification system for notifying implantable cardiac therapy device (ICTD) patients (and possibly others) in a manner that is comprehensive, integrated, efficient, effective, and quick. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

Notification system for implantable cardiac therapy devices

A cardiac therapy network architecture collects data output by an implantable cardiac therapy device, processes that data, and distributes it to various knowledge workers. The cardiac therapy network implements a presentation architecture that formats and encodes the data using different formats and protocols to facilitate distribution to and presentation on various computing devices that might be utilized by the knowledge workers.
