A sensor-retention structure includes a sensor-support strut and a means for securing a sensor device to the sensor-support strut. A sensor-support arm can be configured to have disposed thereon an at least partially cylindrical sensor device and be associated with one or more sensor-retention fingers projecting from the sensor-support arm and/or a cage structure configured to be secured to the sensor device.

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, a nerve, and/or a tissue of the patient. The prong is constructed to apply pressure to the organ, the nerve, and/or the tissue so as to maintain contact between the contact portion and the organ, the nerve, and/or the tissue without fixing the contact portion to the organ, the nerve, and/or the tissue. The electrode is provided at the contact portion of the prong, is configured to contact the organ, the nerve, and/or the tissue, and is electrically coupled or couplable with circuitry that is configured to provide monitoring, therapeutic, and/or diagnostic capabilities with respect to the organ, the nerve, and/or the tissue.

Systems and methods for estimating anatomic alignment between two or more bones are described herein. An example method can include registering an anatomic reference frame. Additionally, the method can include establishing a respective rotational relationship between each of one or more bones and an orientation sensor attached to each of the one or more bones. The method can also include receiving, from each of the orientation sensors, orientation information, and then calculating an orientation of a bone relative to the anatomic reference frame. The method can further include calculating, using the respective orientations of the bones relative to the anatomic reference frame, an anatomic alignment parameter between first and second bones.

A bow shaped pulse meter for new-born patients, comprising a control unit arranged in a central portion of the pulse meter, a first arm with an integrated first electrode and a second arm with an integrated second electrode extending respectively in a bow from opposite sides of the central portion, the integrated electrodes are configured to be in contact with a patient body (not shown) when in use, the electrodes being further electrically connected to the control unit. The pulse meter being distinctive in that the first and second arm and the control unit comprising an integral core element being made of a material having flexible properties to allow the respective arms to bend away from each other when the pulse meter is being arranged into an applying or removing position on the patient's body, the material having further spring back properties so that the arms naturally contract inwards such that the electrodes are maintained in contact with the patient's body when the pulse meter is in the applied position, the pulse meter further comprising a second layer overmolding at least a portion of each arm of the core element, the material of the second layer being electro conductive forming a connection between the electrodes and the control unit.

Stimulation and recording electrode assemblies that are particularly useful for Automatic Period Stimulation (APS). Such embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Certain embodiments include an electrode assembly having cuff including a body and two ears extending from the body. Within the body, at least one electrode is supported and connected to a lead wire assembly. The ears can be brought together to enlarge a gap in the body so that the electrode assembly can be fixated around a nerve. Other embodiments include an electrode assembly including first and second needle electrodes that each have a tip. A body is provided to interconnect the needle electrodes and can be manipulated to move the tips either toward or away from one another. Disclosed embodiments provide nerve monitoring and stimulation in cases where the nerve is only partially dissected.

A sensor-retention structure includes a sensor-support arm configured to hold a sensor device and a stabilizer structure associated with the sensor-support arm and configured to project away from the sensor-support arm and provide stabilizing support for the sensor-support arm.

A delivery system for an intracorporeal device includes a sheath defining one or more lumens shaped to receive a delivery catheter or shaft and a guidewire. The system may include a delivery shaft having a distal coupling feature adapted to releasably couple with a proximal coupling feature of the intracorporeal device. The delivery system may further include a hub through which the delivery shaft and guidewire are passed. The delivery shaft may be coupled to a feature, such as a knob, that enables manipulation of the delivery shaft to decouple the distal fixation feature from the proximal fixation feature of the intracorporeal device in order to deploy the intracorporeal device within a patient.

A method of associating a sensor with a blood vessel includes providing a sensor defining a passage therethrough and at least partially encircling the outside wall of the blood vessel with at least a portion of the sensor. The method further includes compressing the passage through the sensor until a portion of the blood vessel is flattened and mechanically coupling a pressure/force transducer to the outside wall of the blood vessel in an area of vessel wall flattening.

A system for subcutaneously injecting and anchoring a subcutaneous device to a muscle, a bone, and/or a first tissue of a patient, the subcutaneous device including a housing and a clip configured to anchor the subcutaneous device to the muscle, the bone, and/or the first tissue, includes a first surgical instrument and an insertion device. The first surgical instrument includes a first handle and a first dilation portion extending from the first handle. The first dilation portion has a first length and a first width and is configured to spread a second tissue through which the subcutaneous device is to be inserted. The insertion device is configured for insertion through the second tissue spread by the first surgical instrument. The insertion device includes an insertion handle and an insertion portion extending from the insertion handle and being configured to releasably hold the subcutaneous device to implant the subcutaneous device for anchoring to the muscle, the bone, and/or the first tissue.
