The present technology relates to intracardiac pressure monitoring devices, and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include a pressure sensor configured to reside within a first chamber of a heart of a patient, and a pressure transmission element configured to extend from the first chamber through a septal wall to a second chamber of the heart of the patient. When the device is implanted in the patient's heart, the pressure transmission element is configured to transmit pressure from the second chamber to the pressure sensor residing within the first chamber.

A bone clamp (1, 200, 300) for use in fixation of a fractured bone, or prevention of fracture of a bone, the clamp (1, comprising a pair of handles (2a, 2b) joined together at a pivot point (5), the handles (2a, 2b) each having an arcuate jaw (4a 4b), the arcuate jaws (4a, 4b) comprising a first end (7a, 7b) having an opening at a proximal end (12a, 12b) of the jaw (4a, 4b) in communication with a second end (8a, 8b) having an opening at a distal end (14a, 14b) of the jaw (4a, 4b), the first end (7a, 7b) and second end (8a, 8b) in communication via a channel (6a, 6b), in which the channel (6a, 6b) is configured to accommodate a cable, a wire, a suture, a band or other suitable flexible material, and wherein the channel (6a, 6b) is an open channel.

A subcutaneously implantable device includes a housing, a clip attached to the housing that is configured to anchor the device to a muscle, a bone, and/or a first tissue, and circuitry in the housing that is configured to provide monitoring, therapeutic, and/or diagnostic capabilities with respect to an organ, a nerve, the first tissue, and/or a second tissue. The circuitry includes sensing circuitry and/or therapy circuitry, a first power source, and a transceiver. The device further includes an antenna attachment including a head configured to be subcutaneously positioned in a patient and an arm extending between the housing and the head, wherein the head is in electrical communication with the first power source and the transceiver, and wherein the antenna attachment is flexible.

A surgical system used to determine a size of a vessel within a region proximate to a working end of a surgical instrument includes at least one light emitter disposed at the working end, an array of light sensors disposed opposite the at least one light emitter, the array comprising a least one row of light sensors, individual light sensors in the row adapted to generate a signal comprising a pulsatile and a non-pulsatile component, and a controller coupled to the array, the controller comprising a splitter to separate the pulsatile component from the non-pulsatile component, and an analyzer to determine the magnitudes of the pulsatile and non-pulsatile components at the individual light sensors, to determine a first peak magnitude and a second peak magnitude of the pulsatile components, and to determine a resting outer diameter of the vessel based on the first and second peak magnitudes.

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.
