A cannula for passing surgical instruments through tissue. In some instances, the cannula may include a distal flange flexible between a radial configuration and a longitudinal configuration. In some instances, the cannula may also include an actuator configured to move the distal flange between the radial configuration and the longitudinal configuration. In some instances, the cannula may include a valve disposed within the lumen of the cannula, and a cap configured to secure the valve to the cannula. The valve may include a body member having a base and first and second opposing walls extending from the base. In some instances, the valve has an arcuate cutout in the lower surface configured to fit around an instrument shaft inserted therethrough. In some instance, the cannula includes a slit extending an entire length of the cannular to permit an instrument shaft to be inserted and/or removed laterally.

A surgical sheath system having a sheath with a hollow shaft; and a head coupled to and in fluid communication with the hollow shaft, the head having a first mounting feature for coupling a first surgical device; and a second mounting feature for coupling a second surgical device, the second surgical device being a different type of surgical device than the first surgical device.

A interconnectable port is provided. The interconnectable port is adapted to be at least partially placed in an incision in a patient's body. The interconnectable port comprises a first and second port adapted be interconnected to form the interconnectable port, wherein the second port is disconnectable from the first port, wherein the first port is connected to a first portion of a flexible wall, and the second port is connected to a second portion of the flexible wall, and wherein the flexible wall is adapted to form a chamber.

An example introducer is disclosed. An example introducer includes an inner liner including a lumen, a distal region and at least one folded portion extending along the distal region. The introducer also includes a reinforcing member having a length and including at least one spine extending along the length of the reinforcing member. The introducer also includes a sheath disposed along at least a portion of the introducer, wherein the sheath includes at least one perforation, wherein material adjacent to the at least one folded portion is removed from a distal portion of the introducer to form a tip region. The introducer also includes a tip member disposed along the tip region.

A computer-assisted teleoperated surgical system includes one or more manipulator devices and other components. A manipulator device includes a first link, a second link coupled to a distal end of the first link, a third link coupled to the second link, and an instrument actuator coupled to the third link. A joint that couples the second link to the first link defines a yaw axis. A joint that couples the third link to the second link defines a pitch axis. The instrument actuator defines an insertion axis. The yaw, pitch, and insertion axes are fixed in relation to each other and intersect at a remote center of motion. The instrument actuator may insert a surgical instrument along the insertion axis roll and may roll the surgical instrument around the insertion axis. The proximal end of the first link may be coupled to a repositionable setup structure, which may optionally be mechanically grounded to an operating room table. A user control unit includes a processor that acts as a controller, and user inputs at the user control unit teleoperated the manipulator device via the controller.

An introducer may include a layered tubular member having an inner liner including at least one folded portion extending along a distal region of the inner liner in a delivery configuration; a reinforcing member disposed over at least a portion of the inner liner, the reinforcing member including a plurality of longitudinal spines defining a plurality of openings disposed between adjacent longitudinal spines, wherein each folded portion is circumferentially overlapped by one of the plurality of openings; and an outer sheath disposed over the reinforcing member, wherein the outer sheath includes at least one perforation circumferentially overlapping each folded portion; and a tip member fixedly attached to a tapered distal region of the layered tubular member. The inner liner may extend to a distal end of the layered tubular member. At least a portion of each folded portion may terminate proximal of the distal end of the layered tubular member.

Certain embodiments provide an adjustable length infusion cannula having a cannula including a first proximal end and a first distal end, and a hub having a second proximal end, a second distal end, and a central aperture that extends between the second proximal end and the second distal end. The central aperture is configured to accept the first distal end of the cannula and allow the cannula upward movement and downward movement through the hub. The adjustable length infusion cannula also includes a locking mechanism configured to lock the cannula within the hub such that the first distal end extends a first distance past the second distal end of the hub.

The present technology relates to a hemostasis sealing device having a device enclosure with a first seal portion for a medical device and a second seal portion for guide wire sealing. The device enclosure can be generally configured for compressive communication with a housing. The second seal portion can define a split that is in compressive communication with structural elements of the hemostasis sealing device, which can simultaneously provide sealing functionality and allow passage of relatively large-bore devices.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A surgical port is disclosed. The surgical port has a cannular channel. The surgical port also has one or more suture slots in communication with the cannular channel. The surgical port further has a pair of cam grips for each of the one or more suture slots, each pair of cam grips comprising opposing gripping arms configured to allow suture to be pulled through the opposing gripping arms in a direction away from the cannular channel and to resist suture movement in a direction towards the cannular channel.
