A cannula for use in an access assembly includes an instrument valve housing including first and second housing sections and defining a cavity and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism. The guard assembly includes a plurality of guard members. Each guard member of the plurality of guard members includes a ring portion and a flap portion. The flap portions of the guard members of the guard assembly are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.

An implant delivery device may include an implant holding portion proximate the distal end, the implant holding portion being configured to retain a sheet-like implant during implantation of the implant. In addition, the implant holding portion may be configured to receive the implant with a fixed implant supporting flange member configured to support the implant on one side, and a movable implant supporting flange member. The movable implant supporting flange member may be configured to be slidable between a distal position and a proximal position, wherein, in the distal position, the movable implant supporting flange member and secures the implant against the fixed implant supporting flange member, and in the proximal position, the movable implant supporting flange member is withdrawn from the distal end of the implant delivery device, thus enabling release of the implant.

The present disclosure relates to a surgical cannula with a removable seal at one end. The surgical cannula is a wide gauge surgical cannula, that allows materials and tools to be introduced into a body during a surgical procedure. The cannula includes a seal structure at one end, which may be attached to and detached from the cannula body as desired. The seal structure includes one or more valves that retain pressure within the cannula. The one or more valves are configured to allow a tool through the valve(s), while retaining pressure inside the cannula, so that surgical tools may be inserted through the cannula even when the seal structure is attached to an end of the cannula.

A surgical access assembly includes elongated cannula member having proximal end portion and a distal end portion, a cannula housing coupled to the proximal end portion of the elongated cannula member, a balloon anchor coupled to the distal end portion of the elongated cannula member, and a collar having a port disposed along the elongated cannula member and in fluid communication with the balloon anchor. The port includes a first check valve, a second check valve, an actuatable button, and a release valve. The first check valve is disposed between a first end portion of the port and a second end portion of the port thereby defining a first chamber. The second check valve is coupled to the second end portion of the port and defines a second chamber between the second check valve and the first check valve. The actuatable button is configured to control flow of air into the balloon anchor. The release valve is configured to control flow of air out of the balloon anchor.

A retention mechanism for a surgical access assembly includes a first member having a first semi-circular body with first and second ends and a second member having a second semi-circular body with first and second ends. The first end of the first member defines a first recess and the second end of the first member includes a first male connector. The first end of the second member includes a second male connector configured to be received within the first recess and the second end of the second member defines a second recess configured to receive the first male connector. When the first male connector is received within the second recess and the second male connector is received within the first recess, the first and second members are configured to frictionally engage a cannula of the surgical access assembly.

A surgical access assembly including an elongated cannula member having proximal and distal end portions, a cannula housing coupled to the proximal end portion of the elongated cannula member, a balloon anchor coupled to the distal end portion of the elongated cannula member, and a collar disposed along the elongated cannula member and in fluid communication with the balloon anchor. The collar includes a first check valve and a manually actuatable pump. The first check valve is configured to control flow of air into the balloon anchor. The manually actuatable pump is coupled to the first check valve.

A medical device for cleaning a laparoscope can include a service box with a pump and a gas valve. Each of the pump and the gas valve can be in communication with an exit valve. The pump can be configured to draw fluid into the service box, along a fluid feed line, and out of the exit valve. The gas valve can be configured to selectively permit gas into the service box, along the fluid feed line, and out of the exit valve. The medical device can include a trocar that can be in communication with the exit valve via a flexible tubing. The trocar can include a hub and a cannula. The hub can be configured to receive and direct the laparoscope through the cannula. The cannula can be configured to receive fluid and gas from the exit valve and direct the fluid and gas to the open end.

An apparatus for providing instrument access through a gel pad of a surgical access device disposed to seal an opening to a body cavity of a patient is disclosed. The apparatus includes a stem having a bore extending therethrough, the stem having a length sufficient such that when the stem is inserted through the gel pad a distal end of the stem protrudes beyond an inner surface of the gel pad. The bore is sized to permit an instrument to be inserted through the bore and through the opening into the body cavity. The stem includes a flanged opening to the bore that remains external to an outer surface of the gel pad and limits the insertion of the stem through the gel pad. The apparatus also includes a displaceable seal disposed within the bore below the flanged opening, the displaceable seal being operable to seal the bore prior to insertion of the instrument and to displace to permit insertion of the instrument while maintaining the seal.

Trocar retractor apparatus and methods for use are described where an apparatus for positioning an instrument may generally include a substrate having a first surface and a second surface opposite to the first surface, an instrument positioning guide projecting from the first surface of the substrate, and one or more suction assemblies positioned along the second surface and in fluid communication with an interior of the substrate. The one or more suction assemblies may be attachable to a tissue region via a vacuum force applied through the one or more suction assemblies. The apparatus may also have the substrate configured to maintain a predetermined configuration when the vacuum force is applied.
