Devices, systems, and methods are described including an invasive medical device with a magnetic region. The magnetic region can include a discontinuity in the magnetic region providing a diameter transition, a plurality of spaced magnetic regions can be provided or the magnetic regions can be encoded with data. Systems and methods are described that include ways to read the data.

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a mounting ring which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the mounting ring and the clip.

A device and method for a guidance sheath is provided which is configured to prevent laceration or puncture of nerves, blood vessels and surrounding tissue, during positioning of a coaxially located needle employed for various medical procedures, such as, the administration of an anesthetic blockade, neuromonitoring, electromyography or a therapeutic intervention.

A device and system for and methods of using an ultrasound probe housing containing ultrasound probes configured to produce images inside the body of a patient for procedures requiring needle or probe insertion. The ultrasound probe housing can be configured with a guide channel cut-out or aperture between the ambient side and body side of a patient. A needle guide assembly may be pivotally connect internal to the guide channel cut-out or aperture of the ultrasound probe housing at a pivot point such that during use the needle enters the patient through the needle guide assembly within the ultrasound probe housing so that the needle can be visualized by the ultrasonic probes in real time. The ultrasound probe housing may also provide an adhesion or suction quality to the body side of the device to facilitate aspects of the invention.

A low profile endocavity needle guide device for an ultrasonic probe is disclosed. The device includes a needle guide and a clamp assembly. The needle guide is a tubular member configured to enable an elongated needle to be extended through it. The clamp assembly includes a first clamp member, a second clamp member and a slidable member. The first clamp member is pivotable with respect to the second clamp member between an engagement position and a release position, and vice versa. The slidable member is mounted on the first clamp member and includes a low profile projection which engages a ramped surface of the first clamp member to pivot the first clamp member to the engagement position when the projection is slid up the ramped surface, and to enable the first clamp member to move to the release position when the projection is slid down the ramp surface.

A device for use in the treatment of hemorrhoids. The device includes an elongated tube-shaped element that includes a forward end and an aft end. The aft end provides access to the interior of the tube-shaped element. The tube-shaped element extends along a longitudinal axis L and includes at least one opening formed between the forward and aft end. The device includes an anal mucosa support device removably arranged within the tube shape element. The support device includes at least two cavities to receive anal mucosa. At least one needle guide structure is formed in the elongated tube-shaped element and the anal mucosa support device such that at least one needle is capable of being guided during movement within the tube-shaped element across the at least two cavities in the anal mucosa support device to a position where the needle extends across the opening in the tube-shaped element.

An introducing device for locating a tissue region and deploying an electrode is shown and described. The introducing device may include an outer sheath. An inner sheath may be disposed within the outer sheath. The inner sheath may be configured to engage an implantable electrode. In an example, the inner sheath may comprise a stimulation probe having an uninsulated portion at or near a distal end of the delivery sheath. The outer sheath may be coupled to a power source or stimulation signal generating circuitry at a proximal end. A clinician may control application of the stimulation signal to a tissue region via the outer sheath.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A processing device (1) and method for determining a position and/or orientation for a multi-hole grid template in a medical interventional procedure is disclosed. An anatomical spatial information processing unit (2) receives and/or processes data representative of a target spatial volume in the body, and a grid position sampler (4) generates candidate positions of the grid template. A quality calculator (5) calculates, for each candidate, a quality metric indicating the suitability of the candidate position of the grid template for the interventional procedure. A position selector (6) selects the position and/or orientation from the candidates based on the quality metric. For each candidate, an spatial relationship between each grid hole trajectory and the target volume is determined, and the quality metric takes, at least, this spatial relationship into account.
