Systems and assemblies for use during image-guided medical procedures use surgical support systems with a plurality of elongate legs that have independently adjustable lengths and end portions that adjacently attach to a bracket to provide different lockable orientations accommodating both supine and occipital access for neurological procedures.

Surgical tool support systems including elongate support legs with adjustable lengths and related methods

Methods for surgical navigation use a trajectory frame/guide assembly for use with surgical navigation systems that includes a base having a patient access aperture formed therein. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis and interchangeably holds a single lumen or multi-lumen guide array and a device guide. A device guide can be rotated to align an access channel with a desired lumen path. No x-y actuators are required and a virtual guide array may also or alternatively be used to identify a desired open channel in the device guide for the preferred trajectory path.

Methods for surgical navigation

Trajectory frame assemblies for image guided surgical systems have a trajectory frame with a support column that can removably secure different components such as a tracking probe and an MER driver adapter to define and/or follow a desired intrabody trajectory. The trajectory frame assemblies include fins attached to the column support and a platform optionally with an X-Y table and/or arcuate reference brackets that are attached to the trajectory frame assemblies and can hold a reference frame with fiducials.

Devices for surgical navigation systems

Systems and methods for transferring fluid to or from a subject use a set of MRI compatible components that can aspirate intrabody structure and/or fluids. The components include a device guide, a semi-rigid guide sheath configured to slidably extend through the device guide, a stylet releasable coupled to the guide sheath and extending a fixed distance out of a distal end thereof, and a cannula coupled to flexible tubing that is releasably interchangeably held in the guide sheath in lieu of the stylet.

A passive MRI-compatible guidewire includes an elongate, flexible tubular shaft, an elongate core wire of non-ferromagnetic material, and an elongate spring coil of non-ferromagnetic material axially surrounding the elongate core wire to form a distal end portion. The core wire includes opposite first and second end portions separated by an intermediate portion. The intermediate portion has a round cross-section, and the first and second end portions each have a non-round cross-section. The first end portion of the core wire resides within an inner lumen of the tubular shaft and is secured therewithin. The spring coil includes opposite first and second ends, and the spring coil second end is secured to the core wire second end portion via polymeric material that forms a rounded distal tip of the guidewire. The guidewire includes a plurality of spaced-apart, passive MRI-visible markers.

MRI-compatible guidewire

A tunneling device for creating a pathway in subcutaneous tissue of a person's body. The tunneling device includes a member having two ends, where each of the ends defines an insertion surface that facilitates the insertion of the ends into the subcutaneous tissue of the person's body. The tunneling device includes an interchangeable handle connectable to each of the ends. The handle defines a grasping surface and an opening. The opening is configured to receive either of the ends. The grasping surface enables a user to securely hold the handle with one hand to forcibly move the member through the subcutaneous tissue of the person's body to create the pathway in the subcutaneous tissue, and pull a cable of an implant device through the created pathway.

Surgical tool

A tool for coring a hole in a patient's body. A housing includes a first opening and a second opening and has an axis extending therebetween. A shaft is movably positioned along the axis. A blade assembly is attached to one end of the shaft. The blade assembly comprises a cup having an open end and a closed end and a cutting edge formed around the open end. An interface is attached to the housing, which is shaped and dimensioned to communicate with a connector used to connect a medical device to a the patient's body.

Surgical tool for coring precise holes and providing for retrieval of tissue

Surgical devices such as a device guide for a trajectory frame for image-guided procedures, is configured with first and second elongate and cooperating semi-circular members that together define a longitudinally extending open channel and that can separate along longitudinally extending split lines into discrete first and second elongate semicircular members. The surgical devices with the first and second semi-circular members can include a device guide and dock and lock inserts that are detachably held by dock and lock members to a guide support column that also concurrently holds the device guide during at least part of an image guided procedure.

Split-guides for trajectory frames for medical interventional systems and methods

A tool for coring a hole in a portion of a patient's body. A cylindrical sheath includes a hollow bore open at both ends. A shaft is axially movable back and forth within the bore. A blade assembly is attached to one end of the shaft. The blade assembly comprises a hollow open cup portion having a closed end and a cutting edge formed around the margin of the open end. An interface is attached to the sheath which is shaped and dimensioned to communicate with a connector used to connect a medical device to a patient's body.

A trajectory frame for use with surgical navigation systems includes a base having a patient access aperture formed therein. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis. An elongated guide is secured to the platform and includes opposite proximal and distal end portions and a bore that extends from the proximal end portion to the distal end portion. The guide is configured to removably receive various devices therein for quick release therefrom, including an optical tracking probe (which may be a universal tracker) detectable by a camera-based tracking system or an EM probe detectable by an EM navigation system, a microelectrode probe driver adapter, a drill guide and drill bit, skull fixation device and driver, and a catheter guide.
