The invention relates to a marker body (10) for marking breast tissue for radiotherapy. The marker body (10) has an at least partly tube-like body (12) which is made from a soft elastic material and carries multiple radio-opaque marker elements (18). The at least partly tube-like body (12) is designed so that it offers hardly any resistance to an external, deforming force, but returns to its original shape in the absence of external forces. The at least partly tube-like body (12) has two free longitudinal ends (14, 16) which can be detachably interconnected or are interconnected, resulting in a tubular ring.

A tissue marking system includes a tissue marking beacon and a near-infrared (NIR) camera configured to detect emission of pulsatile NIR light from the tissue marking beacon. The tissue marking beacon is suitable for being injected into a tumor to mark a position and depth of the tumor for treatment. NIR light is emitted from a light-emitting diode (LED) positioned on the tissue marking beacon and is detected by the NIR camera. A pulsatile emission of NIR light from the LED is controlled to by synchronized with a data capture rate and/or detector exposure (shutter) of the NIR camera.

A surgical device comprising an elongated body, a tissue penetrating apparatus and a light projector. The elongated body can reach with distal end thereof a surface of an organ within a subject's body. The tissue penetrating apparatus can be extended from the elongated body distal end along a curved penetration path restricted to a chosen penetration plane. The light projector can generate a shaped illumination on the surface of the organ indicative of an intersection of the penetration plane with the surface of the organ.

Devices, systems, and methods of imaging a blood vessel are provided. For example, the method can include obtaining fluoroscopic image data of a region of interest in a blood vessel using an x-ray source; obtaining intravascular ultrasound (IVUS) data at a plurality of positions across the region of interest using an IVUS component disposed on an intravascular device; processing the fluoroscopic image data and IVUS data, including: determining, using the fluoroscopic image data, a position of the intravascular device with respect to the x-ray source at each of the plurality of positions across the region of interest; co-registering the fluoroscopic image data and the IVUS image data; and generating, a model of the region of interest including position information of a border of a lumen of the blood vessel at each of the plurality of locations; and outputting a visual representation of the model of the region of interest.

Medical appliances including reinforcing bands and radiopaque marker bands are disclosed. In some embodiments, bands may comprise two or more material layers. A first layer may control the mechanical properties of a multilayered marking band, and a second layer may exhibit greater radiopacity than the first layer. Bands may also comprise a single layer.

A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.

A kit for a fiducial marker-based registration of preinterventional image data to an intra-interventional scene is disclosed. The kit comprises: at least one first component, wherein the first component is configured for attachment to a body of a patient, wherein the first component comprises at least one base part of an arresting mechanism, at least one second component, wherein the second component comprises at least one fiducial which is localizable in the preinterventional image data, wherein the second component comprises at least one first counterpart of the arresting mechanism, at least one third component, wherein the third component comprises at least one mounting unit for mounting a spatially localizable tracking object on the third component, wherein the third component comprises at least one second counterpart of the arresting mechanism;
wherein the second component and the third component are selectively attachable to the first component by establishing a releasable mechanical connection between the base part and the first counterpart or between the base part and the second counterpart.

The present invention comprises an apparatus for facilitating the acquisition of a scan during an intraoral scanning procedure using an intraoral scanner, including: an elongate body having an attachment portion configured to attach the elongate body with an implant in a patient's mouth, the implant having a longitudinal axis, whereby the elongate body is adapted to extend substantially perpendicular to the longitudinal axis of the implant when mounted to the implant; the elongate body having a substantially planar upper surface and one or more side walls extending downwardly away from the upper surface; wherein the upper surface and the one or more side walls are observable in a resulting scan when the intraoral scanner scans the apparatus in a direction perpendicular to the upper surface.

The invention extends to a kit including a plurality of items of the apparatus and to a method of performing an intraoral scanning procedure.

Various embodiments of a physical instrument are described herein. The physical instrument comprises a reference array platform having a top surface and a bottom surface. A reference array including one or more different fiducial markers is disposed on the top surface of the reference array platform. The reference array platform may have a bent physical configuration or a tilted physical configuration. An adhesive layer is disposed on the bottom surface of the reference array platform.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
