摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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assembly to allow target fluid to be “front-loaded” into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.

摘要： 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.

摘要： A surgical base assembly for an MRI-guided interventional system includes a base body, a plurality of thumbwheels held by the base body and coupled to a respective plurality of threaded members that extend therethrough whereby a user can rotate the thumbwheels to lift the base body to a desired stand-off location relative to patient. The base assembly can couple to a trajectory defining an intrabody trajectory axis and being configured to guide placement of an interventional device in vivo. The threaded members can have sharp tips configured to penetrate bone and/or tissue of the body.
