Abstract: A colostomy device, which can be referred to as an endoluminal stoma channel, is provided which incorporates a generally cylindrical membrane, with a ring located at either end: an inner luminal ring which is located within the bowel and an outer ring which is rolled over itself to abut against the skin, to which a colostomy bag may be attached. In a corresponding system (stoma discharge control system), the colostomy device (endoluminal stoma channel) is associated with a cover or cap that can facilitate control of discharge from the stoma, and various cover/cap structures are described. Corresponding methods are described.

Abstract: An implantable graft, which may be inserted into a fistula tract to occlude the primary opening of the fistula, is provided. The graft may have a curved, generally conical shape with a trumpet-like head end that continuously tapers to a smaller tail end. The graft may be an integral unit made of a single material, such as a heterograft material. Methods of closing single and multiple fistulae are also provided.

Abstract: Systems, devices, and methods capable of retracting organs are disclosed. In one embodiment, a retractor body comprises a deformable resilient frame defining a central opening and a deformable membrane extending across a portion of the central opening wherein the deformable resilient frame is arranged for complete disposal within the body of a patient and for varying the size of the central opening. In some exemplary embodiments, the retractor is arranged to form a helically coiled arrangement for insertion into the body of a patient. Delivery devices for delivering a deformable resilient retractor and methods of delivery are also disclosed.

Abstract: An implantable graft, which may be inserted into a fistula tract to occlude the primary opening of the fistula, is provided. To prevent unintentional displacement of the graft or extrusion of the graft from the fistula of a patient, the graft may be provided with a cap that extends laterally from at least one end of the body of the graft, where the cap may be integral with the body of the graft, attachable to at least one end of the body of the graft, and/or moveable along the body of the graft. The graft may also have a tail that extends from one end of the body of the graft to assist in placement of the graft in a fistula tract. The graft may be an integral unit made of a single material, such as a heterograft material, or may include distinct components made of the same or different materials. Methods for closing a fistula tract are also provided.

Abstract: An anastomotic sleeve or “cup” protection device incorporating distal and proximal sleeves or “cups”, also incorporating a staple-line buttress. The proximal colon is inserted into the proximal sleeve or cup and the shaft of the stapler anvil is passed through a hole in the closed end of the sleeve or cup. The distal sleeve or cup is placed over the head of the staple shaft, and inserted into the rectum for anastomosis. Closure and firing of the stapler creates a staple buttress line at the anastomosis, the proximal sleeve prevents leakage from the proximal colon and the distal sleeve protects the distal colon or rectum from anastomotic leak.

Abstract: A method of occluding a defect in a patient is provided. The method includes inserting a placement member, such as a wire guide, into a defect; advancing the placement member to a desired location; inserting the placement member into a lumen in an occluding member, such as a plug or a graft; and advancing the occluding member to the desired location by inserting the placement member into a lumen in a pusher member and pushing the occluding member with the pusher member until the occluding member reaches the desired location. Medical devices and systems for occluding defects are also provided.

Abstract: A biocompatible deformable retractor provides desired advanced organ retaining during surgical procedures. The retractor is generally self-retaining once deployed and provides surgical field without the interference from the retained organs. The deployed retractor may adopt convex, planar, or concave configurations inside a body cavity. The retractor comprises a deformable resilient frame and a deformable membrane, is approximately planar or a non-planar convex shape in its natural un-deformed configuration. The membrane can be transparent to provide additional viewing capability of the retained organs.

Abstract: A fiber-optic endoscopic instrument (Fistuloscope) is used to visualize anorectal fistula, and to accurately identify the course through the fistula. The instrument can be used to flush the fistula, to close the fistula tract by means of injecting sealants or placing grafts in the tract of the fistula or to pass setons, micro-instruments or other means to treat and seal the tract.

Abstract: A hemorrhoidal ligator and anoscope system used to facilitate ligation of internal hemorrhoids. The ligating device consists of head, shaft and firing handle assemblies and is capable of storing and releasing multiple rubber bands singularly. The ligating device comprises an inner cylinder that is removable for disposal or reloading for reuse. The inner cylinder may also be configured with a disposable sleeve, the sleeve being disposable or capable of reloading. A modified loading cone is provided for facilitating loading of the rubber bands onto the inner cylinder or the inner cylinder sleeve 9. The anoscope is configured with three lateral apertures that coincide with the anatomic locations of the internal hemorrhoids in man and thus, simultaneously expose all three hemorrhoids for ligation and grading.

Abstract: A pair of sensors (20A and 20B) are mounted at the entrance to a germ sensitive area. When a person enters the area the sensors are activated in sequence, indicating the direction of movement of the person. An indicator, such as a light or sound alarm is mounted upon an antiseptic dispenser, located within the area. The alarm is actuated by the movement and is de-activated once antiseptic is dispensed from the unit. Likewise when the person moves out of the germ sensitive area, the alarm on a dispenser unit located outside the area is energized and is de-activated upon dispensing of antiseptic.
