Surgical instrument tracking systems, methods and devices are described. The system can include tracking devices configured to detect location events. The tracking device can include sensors, circuits, power sources, memories, and radio interface. The tracking devices can automatically determine a location of the tracking device when the tracking device detects a location event. The tracking device can automatically transmit the location and information related to the location event to a data analytics platform. The data analytics platform can allow a user to track multiple surgical instruments and surgical instrument tray in order to accurately determine when surgical instruments should be replaced, and how efficiently the surgical instruments are used.

A computer-implemented method plans a position of a tracking reference device for referencing a position in a medical environment. The method includes a determination of avoidance regions in which a tracking reference device should not be placed so as to safeguard proper tracking of the tracking reference device and/or an instrument tracking reference device which is attached to a medical instrument. The avoidance region is a region lying, from the point of view of a tracking device for tracking the tracking reference device, in the shadow of an envelope surrounding at least one medical instrument. Additionally or alternatively, an avoidance region may lie in between the position of the tracking device and the envelope to avoid a shadowing, by the tracking reference device, of an instrument tracking reference device attached to the medical instrument. Information describing the position of the at least one avoidance region is displayed to a user, and also information about the position of a region which is suitable for placement of the tracking reference device can be displayed to the user.

An elongate medical device having an axis comprises an inner liner, a jacket radially outward of the liner, a braid comprising metal embedded in the jacket, a sensor, and at least one wire electrically connected to said sensor. The at least one wire is one of: embedded in the jacket and optionally disposed helically around the braid; extending longitudinally within a tube which extends generally parallel to the device axis and wherein the tube is embedded in the jacket; and disposed within a lumen, wherein the lumen extends longitudinally within the jacket.

A technique for determining a need for a re-registration of a patient tracker with medical image data of a patient is presented. The patient tracker comprises an acceleration sensor configured to generate inertial data indicative of an acceleration of the patient tracker. A method implementation of the technique comprises the following steps performed by a processor: receiving inertial data acquired by the acceleration sensor, analyzing the received inertial data, or data derived therefrom, with respect to at least one first predetermined condition indicative of a drift of the tracker or an impact on the tracker, and generating, when the at least one first predetermined condition is fulfilled, at least a first re-registration signal.

A system for constructing fluoroscopic-based three-dimensional volumetric data of a target area within a patient from two-dimensional fluoroscopic images including a structure of markers, a fluoroscopic imaging device configured to acquire a sequence of images of the target area and of the structure of markers, and a computing device. The computing device is configured to estimate a pose of the fluoroscopic imaging device for at least a plurality of images of the sequence of images based on detection of a possible and most probable projection of the structure of markers as a whole on each image of the plurality of images. The computing device is further configured to construct fluoroscopic-based three-dimensional volumetric data of the target area based on the estimated poses of the fluoroscopic imaging device.

An ENT tool has a tool chassis having a chassis channel and a tool chassis distal end. A tubular probe is dimensioned to be inserted into a human patient orifice, the probe is rotatable about a probe axis of symmetry, and the probe has a probe proximal end rotatingly connected to the tool chassis distal end. A balloon insertion mechanism is slidingly located within the chassis channel, and is configured to fixedly accept a balloon sinuplasty mechanism penetrating the tubular probe. A guidewire adjustment section is fixedly attached to the balloon insertion mechanism, and the section has a rotatable enclosure. A plurality of rollers are disposed within the enclosure and are configured so that on rotation of the enclosure the rollers grip and rotate a guidewire positioned between the rollers, and, absent rotation of the enclosure, release the guidewire and permit distal and proximal translation of the guidewire.

Techniques for segmenting a percutaneous medical procedure based on one or more determinable phases. The techniques may include obtaining a first set of features over a first time period. The first set of features may be derived from instrument telemetry data corresponding to an endoluminal scope instrument. The technique may also include obtaining a second set of features over the first time period. The second set of features may be derived from instrument telemetry data corresponding to a percutaneous needle instrument. Based on the first set of features and the second set of features, the techniques may classify at least a portion of the first time period as a first phase of the percutaneous medical procedure.

The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis and including a proximal end and a distal end. The medical probe further comprises an expandable basket assembly proximate the distal end of the tubular shaft. The basket assembly comprises a plurality of C-shaped spines and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that a spine extends through the lumen of each of the one or more electrodes. The spines converge at a central spine intersection at a distal end of the basket assembly. Each spine comprises a respective end connected to the distal end of the tubular shaft.

The disclosed technology includes a medical probe including a tubular shaft having a proximal end and a distal end. The tubular shaft can extend along a longitudinal axis. The medical probe can include an expandable basket assembly proximate the distal end of the tubular shaft. The expandable basket assembly can include a single spine comprising a resilient material extending generally linearly along the longitudinal axis in a collapsed form and forming a spiral member defining a generally spherical outer periphery in an expanded form. One or more electrodes can be coupled to the single spine. Each electrode can include a lumen offset with respect to a centroid of the electrode so that the single spine extends through the lumen of each of the one or more electrodes.
