The instrument ports for introducing instruments into a surgical site that are disclosed herein include a port body having a channel running therethrough from a proximal end to a distal end, an instrument sleeve in slidable contact with the channel, creating a gap therebetween, and a fluid flow element for removing emboli efficiently from the instrument port, wherein the fluid flow element includes the gap. Disclosed fluid flow systems are for use in the disclosed instrument ports. Methods are also disclosed for removably securing an instrument sleeve to a port body by anchoring the instrument port to heart tissue, making at least one flood line in a channel, flushing out emboli, and performing surgery with the instrument port.

A surgical access device includes a seal housing and a roller disposed in the housing and defining a working channel. The roller may be stationary or moveable within the seal housing to form both a zero seal in the absence of an instrument, and an instrument seal in the presence of an instrument. Rotation of the roller is contemplated and low-friction surfaces are discussed to reduce instrument insertion forces. Multiple rollers, wiper elements, low-friction braid, pivoting elements and idler rollers are contemplated. The rollers will typically be formed of a gel material in order to facilitate the desired compliance, stretchability and elongation desired.

The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.

A valve mechanism (3) for attaching to a proximal end (4) of a trocar cannula (2) for minimising leakage of insufflating and other gases proximally from the trocar cannula (2), comprises a housing (7) adapted for securing to the trocar cannula (2) adjacent the proximal end (4) thereof. The housing (7) defines an instrument bore (22) extending from a proximal end (23) to a distal end (21). A distal valve (28) is located adjacent the distal end (21) of the instrument bore (22) and is pivotal from an open state to a closed state. A proximal valve (40) is located towards the proximal end (23) of the instrument bore (22), and comprises first and second valve members (41) and (42) which are urgeable from a withdrawn state clear of the instrument bore (22) to an engagement state sealably engaging an instrument in the instrument bore (22) for sealing the instrument bore (22). A detecting probe (34) pivotal about a primary pivot axis (35) is urgeable distally from a first state to a second state by the distal end of an instrument passing distally through the instrument bore (22). A drive transmission (74,108) transmits drive from the detecting probe (34) to the proximal and distal valves (40,28), so that as the detecting probe (34) is urged from a first state to a second state the distal valve (28) is urged into the open state and the proximal valve (40) is simultaneously urged from the withdrawn state to the engagement state to minimise leakage of gas proximally through the instrument bore (22) and to minimise contact of an instrument with the proximal and distal valves (40,28).

The surgical robotic access system provides access for robotic instruments and/or actuators including the introduction, operation and withdrawal of such robotic manipulators into a body cavity without permitting the escape of pressurized fluid or gas. The surgical robotic access system also provides a multi-faceted range of movement without touching or effecting pressure on the opening in the patient's body cavity.

An insertion device that allows gaining access to the left ventricle of the heart, via the tissue forming the wall of the right ventricle and via the ventricular septum, which includes a tubular shaft with a lumen extending there through, the shaft comprising distal, proximal and central sections, whereby the distal and proximal sections are disc-shaped extended thus forming each a double disc and whereby the central section links the distally placed double disc with the proximally placed double disc and whereby pressure valves are fixed inside the shaft preferably on its distal and proximal end.

Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.

A laparoscopic port closure device is described. The device allows for the deployment of a suture internally into an abdominal wall and the subsequent use of that deployed suture to effect a closing of the wound that was used for the port. The deployed suture may be used during the surgical procedure to effect a securing or anchoring of the device.

A system and method for passing an end portion of a needle system from a body cavity to an outer environment through a laparoscopic port is provided. The system comprises a seal bridge which comprises an elongated body. The seal bridge is telescopically introducible at a first proximal end, through a first lumen in the port and bypassing a seal mechanism of the laparoscopic port. The seal bridge is adapted to be inserted through the proximal opening port to be deployed in the lumen of the port and thereby bridging across and/or deactivating the seal of the port. The method comprises positioning a distal portion of a needle shaft from within the body cavity into the port lumen and across the seal opened by the seal bridge.

An object of the present invention is to provide an endoscopic surgery device and an outer tube, capable of easily obtaining an image desired by an operator to facilitate treatment as well as of performing minimally invasive surgery. In the endoscopic surgery device and the outer tube, an endoscope and a treatment tool are inserted into a body cavity through an outer tube. The outer tube is provided with a built-in slider. The slider is provided so as to be axially movable in the outer tube body. The endoscope and the treatment tool, inserted into the outer tube, are held by the slider. Moving the treatment tool allows endoscope to be moved in conjunction with the movement of the treatment tool.
