The heart valve assessment systems described herein advantageously provide indicators of a heart valve condition, such as a pressure gradient or a valve regurgitation index. The heart valve assessment systems can provide indicators of a heart valve condition during a heart procedure. A pressure gradient indicates a severity or measurement of the narrowing (or stenosis) of a valve by the increase in pressure behind it. A valve regurgitation index indicates a leakiness measurement of a valve.

A wireless intraluminal device (102) and an associated system for treating and diagnosing patients are provided. In one embodiment, the wireless intraluminal device (102) includes a flexible elongate member (158) including a proximal portion (106) and a distal portion (108); a sensor assembly (116) coupled to the distal portion of the flexible elongate member; a cable (117) coupled to the sensor assembly and extending along the flexible elongate member; and a wireless transceiver (252) positioned within the flexible elongate member, wherein the wireless transceiver is in communication with the sensor assembly via the cable. A wireless communication component (104) wirelessly transmits a sensor measurement collected by the sensor assembly to a sensor measurement processing system (132) via a wireless link (150) for physiological data generation at the sensor measurement processing system.

Systems and methods are described for functional brain mapping using neuronavigational equipment and additional features. For example, some implementations described combine novel cortical stimulator tools with stereotactic navigation for three-dimensional position tracking of the cortical stimulator tools. In some implementations, the systems and methods described herein can be used on an awake patient. In some implementations, the systems and methods described herein can be used on a patient that is asleep, via motor evoked potentials (MEPs), phase reversal, or electromyography (EMG) monitoring. Accordingly, in some cases sensory and language regions of the brain can be identified in addition to motor regions.

One variation of a method for tracking objects within a surgical space during a surgery includes: based on a first image depicting the surgical space at a first time, detecting a first object and a constellation of objects in the surgical space, estimating distances from each object—in the constellation of objects—to the first object, and calculating a contamination risk of the first object based on contamination scores and distances to the first object for each object in the constellation of objects; calculating a contamination score of the first object based on a combination of the contamination risks of the first object during the surgery; and, in response to the contamination score of the first object exceeding a threshold contamination score prior to contact between the first object and a patient, serving a prompt within the surgical space to address sterility of the first object.

Novel tools and techniques are provided for implementing intelligent assistance (“IA”) or extended intelligence (“EI”) ecosystem to placement procedures for cardiac implantable electronic device (“CIED”). In various embodiments, a computing system might analyze received one or more first layer input data (i.e., room content-based data) and received one or more second layer input data (i.e., patient and/or tool-based data), and might generate one or more recommendations for guiding a medical professional in performing a CIED placement procedure in a heart of the patient, based at least in part on the analysis, the generated one or more recommendations comprising 3D or 4D mapped guides toward, in, and around the heart of the patient. The computing system might then generate one or more XR images, based at least in part on the generated one or more recommendations, and might present the generated one or more XR images using a UX device.

A system for closing a blood vessel includes a housing having a proximal end and a distal end and configured to be held in the hand of a user, an elongate body extending from the distal end of the housing, a distal housing having a proximal end coupled to a distal end of the elongate body and having a cavity including an opening on a side of the distal housing, a lumen passing through the elongate body and terminating at the cavity of the distal housing and configured to couple to a vacuum source, a sensor carried by the distal housing adjacent the cavity and configured for identifying a blood vessel, wherein the lumen is configured to maintain a vacuum within the cavity when a probe having a vessel closure module is inserted within the lumen and the vessel closure module is within the cavity.

A method includes receiving analog body-surface signal from body-surface electrode, and multiple analog unipolar signals from multiple unipolar electrodes of an invasive probe. A first unipolar electrode is assigned to serve as a common electrical ground and a common timing reference for the analog unipolar signals and the analog body-surface signal. The analog unipolar signals are digitized to produce digital unipolar signals sampled relative to a digital ground. Defined are an analog bipolar signal between the first unipolar electrode and a second unipolar electrode of the probe, and digital bipolar signal formed from the first unipolar electrode and the second unipolar electrode. Ground and timing offsets between the analog bipolar signal and the digital bipolar signal are estimated, while the first unipolar electrode is connected to the digital ground. The ground offset and the timing offset are applied in measuring a third unipolar signal, sensed by a third unipolar electrode.

A deep intracranial electrode which comprises a flexible wire, an electrode contact, a connector and a shield sleeve, one end of the flexible wire is connected to the electrode contact, the other end connected to the connector; the shield sleeve sheathes around the flexible wire, a sum of a length of a part of the flexible wire arranged outside the shield sleeve and a length of the shield sleeve being adjustable. When the shield sleeve sheaths around the flexible wire, the length of the flexible wire inside the radio-frequency magnetic field of the magnetic resonance equipment may equal to a sum of the length of the shield sleeve and a length of the flexible wire outside the shield sleeve.

Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide having a bone dislodging member adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint, and a bone harvesting assembly adapted to extract and collect dislodge bone material from the bone dislodging member after creation of the pilot SI joint opening.

Stent apparatuses are provided. In some embodiments, the stent apparatus comprises: a tubular body; and at least two induction loops capable of generating an electrical current in the presence of one or more of magnetic, electrical, and radiofrequency energy. The stent apparatus may be placed in a non-target bodily tissue during surgery and used to sense the proximity of an electrosurgical instrument to prevent injury to the non-target tissue. Also provided herein are related systems and methods for protecting and/or mapping the non-target bodily tissue having the stent apparatus placed therein.
