A surgical access device includes a cannula body, an anchor, and a first suture retention mechanism. The cannula body includes a housing and an elongated portion extending distally from the housing. The elongated portion defines a longitudinal axis and a channel extending therethrough. The anchor is disposed in mechanical cooperation with the elongated portion of the cannula body and is longitudinally translatable relative to the elongated portion. The first suture retention mechanism extends laterally from the anchor. A suture-receiving channel is defined between a portion of the suture retention mechanism and a portion of the anchor.

A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes a trocar mechanism that includes a trocar member that is at least one of rotatable or articulable relative to a housing of the trocar assembly.

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

An access needle is provided. The access needle includes a needle housing and a needle shaft having a portion disposed within the needle housing. The access needle also includes a lumen within the needle shaft, an entry port at a proximal end of the needle shaft, and a needle tip at a distal end of the needle shaft. The access needle also includes an exit port on a sidewall of the needle shaft, wherein the exit port is disposed nearer the distal end of the needle shaft than the proximal end, and wherein the lumen extends from the entry port to the exit port. The exit port a reduced diameter from the needle shaft. Guide surfaces in the vicinity of the exit port help to reduce snagging or drag of the guide wire. The access needle tip can be formed from nitinol and the guide surfaces can be formed from UV or AB glue. A system and a method for using the access needle are also provided.

Transradial access devices, systems, and methods. An exemplary device of the present disclosure for providing access to a vessel or other luminal organ and to prevent overperforation of the same including a needle having a needle tip and at least one current element positioned thereon or embedded therein at or near the needle tip, a sheath positioned around at least part of the needle, and a protractor in communication with the needle, whereby engagement of the protractor causes the needle tip to protract from the sheath through the aperture, and whereby release of the protractor causes the needle tip to retract through the aperture into the sheath. Activation of the at least one current element can facilitate vasodilation of the vessel or other luminal organ.

A retaining mechanism for releasably securing a trocar assembly within an outer sleeve of an adapter assembly includes a retaining block, a cam wire moveably positioned relative to the retaining block between a lock position and a release position, a retaining block extension maintaining the cam wire relative to the retaining block, a button member in operable engagement with the cam wire, and a pair of retaining members moveable from a first position received within first and second openings of the trocar assembly when the cam wire is in the lock position and a second position spaced from the trocar assembly when the cam wire is in the release position. The retaining members each define a cutout having first and second stepped cutout portions and a smooth transition between the first and second stepped cutouts for receiving the cam wire.

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.

Surgical sealing ports for use with surgical instruments for access of a natural body orifice are provided. In one exemplary embodiment, a surgical sealing port includes a seal housing and at least one retention element. The seal housing is configured to be at least partially disposed within a natural body orifice and defining a plurality of ports. The plurality of ports includes at least one first port configured to control the ingress and egress of fluid between an interior volume of the natural body orifice and an ambient environment, and at least one second port that is configured to form a seal around an instrument inserted therethrough. The at least one retention element is arranged on an exterior surface of the housing and configured to affix the housing to the natural body orifice. Methods for using the same are also provided.

A method for closing an opening in biological tissue of intra-abdominal structures, which includes the steps of (i) providing a tissue closure system that includes a suture guide sub-system for engaging tissue disposed proximate the tissue opening and a suture passer sub-system that slideably engages the suture guide sub-system, (ii) inserting the suture guide sub-system into and through a tissue opening, (iii) inserting the suture passer sub-system with a section of suture engaged thereto into and through a first tissue region, (iv) rotating the suture guide sub-system, (v) inserting the suture passer sub-system with another section of suture engaged thereto into and through a second tissue region, (vi) withdrawing suture guide sub-system, (vii) releasing both sections of the suture captured by the suture guide sub-system, and (viii) drawing both sections of the suture together, wherein the first and second tissue regions are drawn together and the tissue opening is closed.

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.
