Devices for transferring fluid to or from a subject include an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen. The devices also include an elongate needle having opposing proximal and distal ends. The elongate needle is configured so that the distal end of the needle extends out of the distal end of the cannula a suitable adjustable distance. The devices also include a housing with a length adjustment mechanism that adjusts a length between the tip of the needle and the distal end of the tubular cannula.

Intrabody surgical fluid transfer assemblies with adjustable exposed cannula to needle tip length, related systems and methods

Devices for transferring fluid to or from a subject include an extension tube assembly with an axially extending inner tube configured to couple to an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen and an axially extending inner tube. The inner tube extending through the tubular cannula defines an exposed needle tip and is in fluid communication with the inner tube of the extension tube assembly. The needle tip extends out of a distal end of the tubular cannula a suitable distance.

Extension tube assembly and related medical fluid transfer systems and methods

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

A cannula for transferring a substance to and/or from a patient includes a tubular support sleeve and a transfer tube. The support sleeve includes a rigid tubular member defining a lumen extending from a proximal end to a distal end of the tubular member. The transfer tube is positioned in the lumen and extends beyond each of the proximal end and the distal end of the tubular member. The tubular member includes a rigid, MRI-compatible material.

MRI-compatible surgical cannulae for transferring a substance to and/or from a patient

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

Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be 'front-loaded' into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.

Front-loadable fluid transfer assemblies and related medical fluid transfer systems and methods

Circuits and computer program products onboard and/or adapted to communicate with an scanner that electronically recognize predefined physical characteristics of the at least one tool to automatically segment image data provided by the scanner whereby the at least one tool constitutes a point of interface with the system. The circuits and computer program products are configured to provide a User Interface that defines workflow progression for an image guided surgical procedure and allows a user to select steps in the workflow, and generate multi-dimensional visualizations using the predefined data of the at least one tool and data from images of the patient in substantially real time during the surgical procedure.

Image processing circuits for real-time visualizations using MRI image data and predefined data of surgical tools

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.

The disclosure describes assemblies for use during image-guided procedures and can include turret arms and/or longitudinally extending and laterally extending cooperating devices for holding surgical tools such as trajectory guides.
