摘要： 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.

摘要： A gasket for a hemostasis valve includes an annular wall, a membrane, a central protrusion on the membrane, and a plurality of ligaments attached to the central protrusion extending radially to the annular wall. The membrane, central protrusion, and ligaments are divided by slits into a plurality of flaps, with each flap bounded along an outer circumferential edge by the annular wall, along an inner circumferential edge by the central protrusion, and along its radial edges by segments of the ligaments. Two such gaskets can be arranged, back-toback, in a hemostasis valve. To facilitate such assembly, each gasket can include a plurality of positioning protrusions extending axially and a plurality of positioning recesses set into a circumferential surface, with the protrusions and recesses having complementary shapes for proper interconnection and fit between gaskets.

摘要： An attachment for a catheter assembly may include a platform, which may include an upper surface and a bottom surface. The bottom surface may be configured to contact skin of a patient. At least a portion of the upper surface may be configured to support the catheter assembly. The upper surface may support the catheter assembly at an angle with respect to skin of the patient that is approximately equal to an insertion angle of a catheter of the catheter assembly. The attachment may include snap feature coupled to the upper surface of the platform. The attachment may include a blunt cannula extending distally from the snap feature. The blunt cannula and the portion of the upper surface may provide a generally straight pathway for an instrument inserted distally through the attachment into the catheter assembly.
