Access assemblies include an instrument valve housing and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a guard assembly, and a seal assembly disposed distal of the guard assembly. The seal assembly includes a support member including a ring portion and a seal portion disposed within the ring portion. The seal assembly further includes a plurality of seal sections extending from the ring portion of the support member. The support member and the plurality of seal sections are integrally formed.

Seal assemblies for surgical access assemblies

A method of forming a balloon for a surgical access device includes positioning a molding material into a channel defined in a first mold half of a mold and mounting a second mold half onto the first mold half to cover the channel and form a cavity within the mold. The first and second mold halves each includes vent holes extending therethrough that are in fluid communication with the cavity. The method also includes expanding the molding material to conform to the shape of the cavity to form a balloon including protrusions extending radially outwardly therefrom. The protrusions are formed by engagement of the molding material with the vent holes.

A surgical access assembly includes a cannula including an elongated shaft having a proximal end portion including an anchor inflation port and a distal end portion including an expandable anchor. The elongated shaft includes an inner tube and an outer tube disposed over the inner tube. The inner tube includes at least one groove defined in an outer surface thereof that forms an inflation channel with an inner surface of the outer tube. The inflation channel is in communication with the anchor inflation port and the expandable anchor.

A surgical access device includes a cannula body, an obturator assembly, and a fixation mechanism. The fixation mechanism includes at least one wing, a first plurality of magnets disposed on an elongated portion of the obturator assembly, and a second plurality of magnets disposed on the at least one wing. The at least one wing is coupled to an elongated portion of the cannula body and is movable between a first position where the at least one wing is parallel to a longitudinal axis, and a second position where the at least one wing is disposed at an angle to the longitudinal axis. A predetermined amount of translation of the elongated portion of the obturator assembly within a channel of the elongated portion of the cannula body causes the at least one wing to move from the first position to the second position.

A fixation device for folding a seal member includes a frame having a horizontal portion and an upright portion, a press assembly secured to the upright portion of the frame, and a nest assembly secured to the horizontal portion of the frame. The press assembly includes a handle assembly and an anvil assembly operably connected to the handle assembly. The nest assembly includes a clamping assembly, a folding assembly supported on the clamping assembly, a support assembly supported on the folding assembly, and a nest member. The support assembly includes a support plate and a seal clamp for securing a seal member.

Fixture device for folding a seal member

A tissue specimen retrieval bag assembly includes a tissue specimen bag having an open proximal end and a closed distal end, the proximal end including a cuff defined therein and extending therearound. A flexible bag brim is disposed within the cuff and is transitionable between a first, collapsed configuration and a second, expanded configuration. The flexible bag brim includes a cross section configured to facilitate both furling the tissue specimen bag onto itself around the bag brim when the bag brim is disposed in the second, expanded configuration and securing the tissue specimen bag in a desired furled configuration. The flexible bag brim includes a plurality of scallops defined along an inner peripheral surface thereof configured to facilitate furling the tissue specimen bag onto itself.

Rollable tissue specimen bag with improved brim for tenting

A method of manufacturing a seal assembly for a surgical access assembly includes forming a seal assembly having a monolithic construction. The seal assembly includes a support member, seal sections connected to the support member, bridges disposed between adjacent seal sections and interconnecting the adjacent seal sections, and a plurality of standoffs extending from each seal section. The method also includes placing the seal assembly into a treatment bath, cutting the bridges, and folding the seal assembly.

A tissue guard for use with a surgical access device includes an upper portion having: a proximal ring with proximal and distal ends, the distal end having a first mechanical interface disposed therearound; a plurality of fingers extending about the proximal ring that the access device; an inner peripheral surface having an upper channel; and a plurality of second mechanical interfaces disposed about a distal end of the inner peripheral surface. The lower portion includes: a body having a proximal end including a corresponding first mechanical interface disposed therearound configured to engage the first mechanical interface of the upper portion; a lower channel defined within the body including a plurality of corresponding second mechanical interfaces configured to engage the plurality of second mechanical interfaces of the upper portion; and long and short petals disposed of the lower portion to facilitate insertion of the tissue guard within an incision.

Cutting guard

A surgical access assembly includes a cannula including an elongated shaft having a proximal end portion including an anchor inflation port and a distal end portion including an expandable anchor. The elongated shaft includes an inner tube and an outer tube disposed over the inner tube. The inner tube includes a channel extending longitudinally therethrough and first and second openings defined in an outer surface thereof that are in communication with the channel. The channel, the first openings, and the second openings form an inflation lumen with an inner surface of the outer tube. The inflation lumen is in communication with the anchor inflation port and the expandable anchor.
