Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.

The surgical tool (1) is including a main unit (2) including a case (21) and a hollow shaft (22) provided on the case (21), a holder assembly (3) that holds a living tissue (T) in the body cavity, a connector (4) that connects the main unit (2) inserted through the shaft (22) to the holder assembly (3), an operating unit (5) that is provided on the main unit (2) to allow the connector (4) to enter or leave the shaft (22) and a tension adjustor (6) capable of adjusting the tension of the connector (4).

A tissue retention system to assist in maintaining adipose tissue on a patient in a displaced position during a medical procedure to provide access to a body region of the patient includes an anchor pad having a pad length and a pad width. The anchor pad may include a pad body with an adhesive surface thereon, the adhesive being configured to adhere to a patient's skin. The anchor pad also may include an opposing first attachment surface facing away from the adhesive surface. The tissue retention system also may include a tension member having a second attachment surface.

Apparatus for endoscopically retracting tissue, the apparatus comprising a sleeve adapted to be slid over the exterior of an endoscope; a balloon movably mounted to the sleeve; and at least one connector extending from the balloon and configured to be secured to tissue which is to be retracted; wherein the balloon is configured to be moved relative to the sleeve in order to retract the tissue.

A surgical access system that facilitates access to a surgical site through an incision in the patient's body includes a surgical retractor and a fluid delivery or fluid evacuation device. The fluid delivery or fluid evacuation device is coupled to the surgical retractor and is adapted to deliver fluid to the surgical site or evacuate fluid from the surgical site.

A retractor system for securing surgical retractors includes an elastic tether and a cleat. The elastic tether has an elongated side and a predetermined diameter. The cleat includes a base, a head, and a shaft. The base includes an upper surface with a first row of teeth. The head is coupled to the base via the shaft. The head includes a lower surface with a second row of teeth. The first row of teeth are opposite the second row of teeth by less than the predetermined diameter of the tether and are configured to receive and compress the elongated side of the tether. Each tooth of the first row of teeth includes a first gripping surface that extends away from the shaft. Each tooth of the second row of teeth includes a second gripping surface that extends away from the shaft and that is parallel to the first gripping surface of a directly opposite tooth of the first row of teeth.

An umbilical catheterization device that allows a physician to prepare an umbilical cord and apply appropriate retraction to widen vessels to introduce a catheter. The device comprises a base and a plurality of arms. The arms may include retraction devices or may be compatible with independent retraction devices, including but not limited to sutures. The retraction devices are attached to the umbilical cord, and used to provide retraction.

A system for performing minimally invasive procedures in a body lumen may include a flexible catheter having a plurality of lumens including a main lumen configured to receive an endoscope and at least one tool lumen; a first working instrument slidably disposed within a first tool lumen of the at least one tool lumen; a plurality of support elements disposed at a distal end of the catheter, the plurality of support elements being configured to shift between delivery and expanded configurations, wherein in the expanded configuration, the plurality of support elements forms an expanded cage to reshape the body lumen and form a working space; wherein at least one of the plurality of support elements is a tubular shaft having an opening proximate the working space; and a filament extending through the tubular shaft to a clip disposed outside the opening, the clip being manipulatable by the first working instrument.

A device for surgical retraction having a frame flexible to conform to a patient's anatomy, the frame including at least one anchoring member for retaining a tissue retraction member. A stabilizing member is attached to the frame and secures the stabilizing member to a patient, wherein a tissue retraction member applying a force to the frame in a first direction is counterbalanced by the stabilizing member to provide a force in a second opposite direction.
