A system and method for identifying a stimulation location on a nerve is disclosed. The system includes an image-based navigation interface used to facilitate advancing a stimulation element within a patient body toward a target nerve stimulation site. Using the system one determines, separately for each potential target nerve stimulation site, a neuromuscular response of muscles produced upon applying a stimulation signal at the respective separate potential target stimulation sites. The image-based navigation interface is configured to display a graphic identification of which muscles were activated for each respective potential target nerve stimulation site upon applying the stimulation signal.

An electrode apparatus is applicable on a skin with hair of a mammal for measuring an electrical bio-signal. The electrode apparatus comprises cylindrical chambers, each of which comprises a wall, which forms a cavity within the cylindrical chambers, a roof at a first end of each of said cylindrical chambers, a second end of said cylindrical chambers opposite to the first end being open, and at least one electrode. An elongated structure is located within each of the cylindrical chambers, and comprises a first portion parallel to a central axis of a cylindrical chamber within which it is. A first end of the elongated structure, the first end of the elongated structure belonging to the first portion, is attached to the roof. At least one second portion, each comprising a second end opposite to the first end, deviates from a direction of the central axis of a cylindrical chamber within which it is. The elongated structure rotatable in order to bundle hair when applied to the mammal so as to improve a contact of the electrode with the skin of the mammal.

The enclosure houses electronic circuitry configured to measure one or more parameter or provide a therapy. The cap couples to the ground of the electronic circuitry. The first medical device includes a dual band antenna. A first antenna is configured to operate within a first frequency band below 1 gigahertz. The second antenna is configured to operate at a frequency above 1 gigahertz. The second medical device is configured to transmit a radio frequency signal to the first medical device. The first medical device is configured to harvest the energy received from the radio frequency signal to enable the electronic circuitry and perform at least one task.

The present invention provides a tissue anchor and a system and method employing same, the anchors including a body having a first section and a second section reversibly engagable with one another, each section including a plurality of barbs in the form of microneedles projecting from the underside therefore, the barbs on one section being inclined towards barbs on the other section, such that tissue may be captured and deformed between the barbs through displacement of the first section relative to the second section in order to achieve robust retention of the tissue anchor at a deployment site.

Disclosed is an apparatus for measuring bio signals. The apparatus for measuring bio signals includes: a sensor module configured to include a needle sensor to be inserted into the skin; and a main body to which the sensor module is separably coupled, and which is configured to include a controller controlling the sensor module to measure a bio signal through the needle sensor, once the sensor module is coupled.

An anchoring apparatus for a medical microdevice and a method of selectively maintaining the medical microdevice in a predetermined position within a body tissue are provided. The medical microdevice includes a body having longitudinally spaced proximal and distal device ends and a guidewire extending proximally from the proximal device end. The anchoring apparatus includes a selectively expandable anchor having longitudinally spaced proximal and distal anchor ends. A selected one of the proximal and distal anchor ends is connected to the distal or proximal device end, respectively. The anchor self-expands from a collapsed insertion condition to an expanded anchoring condition after insertion into a body tissue to resist post-implantation motion of the microdevice.

A microdevice includes a body having longitudinally spaced proximal and distal device ends and a guidewire extending proximally from the proximal device end. An anchoring apparatus includes an anchor having longitudinally spaced proximal and distal anchor ends. The anchoring apparatus is selectively expandable between a collapsed insertion condition and an expanded anchoring condition within the body tissue. A retrieval apparatus for selectively retrieving the medical microdevice and its associated anchoring apparatus from a target implantation site of a body tissue is described. The retrieval apparatus includes a stylet having proximal and distal stylet ends longitudinally separated by a stylet lumen configured to selectively accept the guidewire. A retrieval sheath has proximal and distal sheath ends longitudinally separated by a sheath lumen. The sheath lumen is configured to selectively and concurrently laterally surround the microdevice and the stylet therewithin for removal from the body tissue.

Systems, devices, methods, and kits for monitoring one or more physiologic and/or physical signals from a subject are disclosed. A system including patches and corresponding modules for wirelessly monitoring physiologic and/or physical signals is disclosed. A service system for managing the collection of physiologic data from a customer is disclosed. An isolating patch for providing a barrier between a handheld monitoring device with a plurality of contact pads and a subject is disclosed.

Methods and devices for implanting an intra-ocular pressure sensor within an eye of a patient are provided herein. Methods include penetrating a conjunctiva and sclera with a distal tip of a fluid-filled syringe and positioning the pressure sensor within a vitreous body of the eye by injecting the sensor device through the distal tip. The sensor device may be stabilized by one or more anchoring members engaged with the sclera so that the pressure sensor of the sensor device remains within the vitreous body. Methods further include advancing a sensor device having a distal penetrating tip through at least a portion of the sclera to position the sensor within the vitreous body and extracting of the sensor devices described herein by proximally retracting the sensor device using an extraction feature of the sensor device.
