An electromagnetic (EM) tracking configuration system employs an EM quality assurance (EMQA) (30) and EM data coordination (DC) system (70). For the EMQA system (30), an EM sensor block (40) includes EM sensor(s) (22) positioned and oriented to represent a simulated electromagnetic tracking of interventional tool(s) inserted through electromagnetic sensor block (40) into an anatomical region. As an EM field generator (20) generates an EM field (21) encircling EM sensor(s) (22), an EMQA workstation (50) tests an EM tracking accuracy of an insertion of the interventional tool(s) through the EM sensor block (40) into the anatomical region. For the EMDC system (70), as EM field generator (20) generates EM field (21) encircling a mechanical interaction of EM calibration tool(s) (80) with a grid (120) for guiding interventional tool(s) through gird (120) into an anatomical region, the electromagnetic data coordination workstation (90) establishes a coordination system for electromagnetically tracking an insertion of the interventional tool(s) through grid (120) into the anatomical region.

A needle lock device includes an outer frame, a plurality of support members mounted to the outer frame and a plurality of needle holders. At least one needle holder is disposed on each of the support members and each needle holder defining a passage configured to receive a needle. The needle lock device further includes a lock mechanism configured to operate each needle holder between a free state, wherein the needle holder is movable relative to the outer frame and allows translation of the needle through the passage, and a locked state, wherein the needle holder is fixed relative to the outer frame and prevents translation of the needle through the passage. Each needle holder may be compressible for varying a size of the passage between the free state and the lock state. Each lock member may comprise a cam profile and is rotatable between a first position and a second position for operating an adjacent needle holder between the free state and the locked state.

Tissue markers may be implanted percutaneously through a needle into soft tissue to locate a site of a procedure at a later date. A medical implantation device for percutaneously implanting a tissue marker can include a housing extending from a proximal end to a distal end. The device may also include an obturator coupler disposed at the distal end of the housing to couple an obturator to the housing, and a guide track extending from a first track opening disposed at a distal end of the track toward a proximal end of the housing. The device can further include an actuator to be received within the guide track, where the actuator includes a cannula coupler disposed at a distal end of the actuator to couple a cannula to the actuator. The device can also include a latch arm configured to lock a position of the actuator along the guide track.

An assembly is disclosed for positioning elongate instruments for percutaneous procedures. The assembly has a first guiding member with a first body, a first guiding hole extending through the first body for receiving a coiled instrument, the first guiding hole having a first axis. The assembly further includes a second guiding hole, wherein the second guiding hole is coaxial with the first guiding hole and has an essentially cylindrical shape. The first guiding hole extends at a periphery of the second guiding hole. A second guiding member has a second body with opposite first and second main surfaces, a third guiding hole having an essentially cylindrical shape and extending through the second body. The second guiding member is attached or attachable to a periphery of the first guiding member such that the third guiding hole has an axis substantially parallel to the first axis.

A method of inserting brachytherapy seeds into a body organ includes grasping a body organ between a frame defining a large central hole and an additional element. A grid defining a plurality of apertures adapted to receive elongate applicators is placed on one side of the body organ. A plurality of applicators are passed through apertures in the first and second grids and through the body organ. The brachytherapy seeds are anchored in the organ through the frame.

The invention relates to a medical device for transporting and positioning a therapeutic emitting element into a treatment channel to be temporarily placed in or at the body of the patient to treat tumours. The therapeutic emitting element is connected to a transport element and which is driven by at least one drive motor. The device has a connecting element comprising multiple connector openings. The connecting element is used for connecting a transport tube to a respective connector opening. The transport tube is connected to an applicator, needle, tube or catheter for driving the transport element into the treatment channel. The device has a selector mechanism through which the plurality of transport elements are driven. An annular guiding arrangement guides the transport elements into connector openings in the connecting element. The annular guiding arrangement also comprises a plurality of spaced outlets. The inlets of the multiple patterns are each connected to an outlet by guiding channels. Each outlet aligns to a connector opening in the connecting element to allow the transport element from each outlet to be driven into the connector openings.

Provided herein are methods of analyzing tissue using a magnetic resonance imaging (MRI) compatible tissue analysis device that includes radio-frequency (RF) tracking and imaging elements. Related kits, systems, and computer program products are also provided.

The present teaching relates to determination of an optimal set of supplying vessel branches for delivering radioactive material to a target region. A centerline representation for blood vessels is obtained based on a 3D image capturing an organ with a target region and a non-target region. Supplying centerline segments, each representing a supplying vessel branch, are identified based on connected supplying centerline points that cover some parts of the target region. An optimal set of supplying vessel branches are selected that satisfy a specified coverage to the target region with a least coverage to the non-target region.
