Abstract: A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

Abstract: A medical device for accessing soft tissue of the brain may include a delivery sleeve assembly including a sheath configured to receive a surgical access device and mate with a socket arrangement of a cranial burr hole device arranged on a patient, and a depth stop arranged on the sheath of the delivery sleeve assembly configured to be selectively adjusted along the sheath to an incremental depth marker associated with the location of a surgical site.

Abstract: A tissue cutting device is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. A delivery sleeve may be selectively provided that is configured to be disposed about the outer cannula for delivery of a variety of devices.

Abstract: A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

Abstract: Selectively lockable holding arrangements for a surgical access assembly are disclosed. One holding arrangement includes a body portion, an engagement barrel and a retaining member configured as a hook at a distal end of the body portion. The engagement barrel is position on a proximal end of the body portion and is configured to be selectively rotated about the body portion when operatively connected to a surgical holding arrangement. A rotation brake is mounted on the body section. The rotation brake is selectively operable to lock the engagement barrel against rotation.

Abstract: A surgical access assembly may include an outer sheath defined by an open distal end and an open proximal end and including a hollow body portion therebetween, and a flexible tool delivery device having a hub and a guide tube, the hub configured to selectively secure to a rim at the proximal end of the outer sheath, and the guide tube configured to extend at least partially into the outer sheath and provide a flexible tool proximate to a tissue.
