An implant includes a housing that houses circuitry that is electrically coupled to one or more electrodes. The implant includes an antenna that is electrically coupled to the circuitry. The antenna has a pre-treatment state in which the antenna is not shaped to receive wireless power for treating a subject, and a treatment state in which the antenna is shaped to receive wireless power and to anchor the implant with respect to a nerve of the subject. Other embodiments are also described.

A surgical device includes a substrate and a first coating that covers at least a portion of the substrate. The first coating includes a first polymer. The first coating having antibiotics dispersed in the first polymer such that the first polymer releases the antibiotics as the first polymer degrades. A second coating covers at least a portion of the first coating. The second coating includes a second polymer. The second polymer includes an alginate. The second coating has a hemostatic agent dispersed in the second polymer such that the second polymer releases the hemostatic agent as the second polymer degrades. The hemostatic agent is selected from epinephrine, tranexamic acid, chitosan and oxidized regenerated cellulose. In some embodiments, systems and methods are disclosed.

A subcutaneously implantable device includes a housing, a clip attached to a top side of the housing, an electrode, a prong, and a sensor in the prong. The clip is configured to anchor the device to a muscle, a bone, and/or first tissue. The electrode is configured to contact an organ, a nerve, the first tissue, and/or second tissue. The prong is configured to contact the organ, the nerve, and/or the second tissue. The electrode is positioned on the distal end of the prong. The sensor is operable to sense a physiological parameter and includes a temperature sensor, an accelerometer, a pressure sensor, a proximity sensor, an infrared sensor, an optical sensor, or an ultrasonic sensor. Circuitry in the housing is in electrical communication with the sensor and the electrode and is configured to sense electrical signals, deliver electrical stimulation, and/or to deliver a signal to a drug pump.

A leadless pacemaker, a leading component, a trailing component and a delivery device are disclosed. The leading component (10) includes a leading end body (100), a first connection member (101) and a second connection member (102). The trailing component (20) includes a trailing end body (200), a third connection member (203) and a fourth connection member (204). When the leading component (10) is connected to or removed from the trailing component (20), the first connection member (101) is connected to the delivery device (30); the leading component (10) can be axially immobilized by the delivery device, and force is applied to the fourth connection member (204) by the delivery device (30) to enable the second connection member (102) to be connected to or separated from the third connection member (203), so that the leading component (10) and the trailing component (20) of the leadless pacemaker can be connected or separated conveniently; in addition, during performing separation and connection, the leading component (10) can be fixed by the delivery device (30) to prevent the leading component (10) from pulling the heart tissue, thereby making separation and connection safer. When the battery of the leadless pacemaker is exhausted, the connection relationship between the leading component (10) and the heart can be kept unchanged, and the trailing component (20) can be conveniently replaced.

A subcutaneously implantable device is implantable into a body of a patient, and includes a prong and an electrode. The prong has a contact portion at or adjacent to a distal end thereof that is configured to contact an organ. The prong is constructed to apply pressure to the organ with spring action so as to maintain contact between the contact portion and the organ without fixing the contact portion to the organ. The electrode is provided at the contact portion of the prong, is configured to contact the organ, and is electrically coupled or couplable with circuitry that is configured to provide monitoring, therapeutic, and/or diagnostic capabilities with respect to the organ.

Methods and apparatuses (e.g., devices and systems) for vagus nerve stimulation, including (but not limited to) sub-diaphragmatic vagus nerve stimulation. In particular, the methods and apparatuses described herein may be used to stimulate the posterior sub-diaphragmatic vagus nerve to treat inflammation and/or inflammatory disorders. The implantable microstimulators described herein may be leadless and batteryless.

An implantable medical system may provide atrioventricular synchronous pacing using the ventricular septal wall. The system may include a ventricular electrode coupled to an intracardiac housing or a first medical lead implantable in the ventricular septal wall of the patient's heart to deliver cardiac therapy to or sense electrical activity of the left ventricle of the patient's heart and a right atrial electrode coupled to a leadlet or second medical lead to deliver cardiac therapy to or sense electrical activity of the right atrium of the patient's heart. A right ventricular electrode may be coupled to the intracardiac housing or the first medical lead and implantable in the ventricular septal wall of the patient's heart to deliver cardiac therapy to or sense electrical activity of the right ventricle of the patient's heart.

An example device includes an elongated housing, a first and second electrode, and signal generation circuitry. The housing can be implanted within a single first chamber of the heart. The first electrode extends distally from the distal end of the elongated housing. A distal end of the first electrode can penetrate into wall tissue of a second chamber of the heart. The second electrode, extending from the distal end of the elongated housing, is configured to flexibly maintain contact with the wall tissue of the first chamber without penetration of the wall tissue of the first chamber by the second electrode. Signal generation circuitry can be within the elongated housing and coupled to the first and second electrode. The signal generation circuitry can deliver cardiac pacing to the second chamber via the first electrode and the first chamber via the second electrode.

The present disclosure provides advantageous post and partition assembly that is configured and adapted to promote modularity and withstand the harsh environment of central sterile processing processes. Modular post assembly may be removed and relocated on tray without additional fasteners or components. Tray and bracket assembly may further provide identification features to correctly associate cataloged reusable medical devices to identified trays.

A leadless cardiac pacemaker device is configured to provide HIS bundle pacing and contains a housing having a tip, a first electrode arranged on the housing in the vicinity of the tip, the first electrode being configured to engage with intra-cardiac tissue, and a second electrode arranged on the housing at a distance from the tip of the housing. A processor is enclosed in the housing and operatively connected to the first electrode and the second electrode. The processor is configured to process a reception signal received by at least one of the first electrode and the second electrode and to generate a pacing signal to be emitted using at least one of the first electrode and the second electrode.
