  • Patent number: 7265098
    Abstract: The present invention relates to improved methods for delivering bioadhesive, bioresorbable, anti-adhesion compositions. Antiadhesion compositions can be made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then used as fluids, gels or foams. By providing a product bag, the compositions can be delivered as gels or as sprays. By dissolving propellant gases in the compositions, the materials can be delivered as foams, which have decreased density, and therefore can adhere to surfaces that previously have been difficult to coat with antiadhesion gels. Delivery systems can also provide mechanisms for expelling more product, and for directing the flow of materials leaving the delivery system. Bioresorbable, bioadhesive, anti-adhesion, and/or hemostatic compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions.

  • Patent number: 7192984
    Abstract: The present invention relates to improved methods for filling the skin for cosmetic or medical purposes. Compositions comprising carboxymethyl cellulose (CMC), polyethylene oxide (PEO) and calcium ions can be made and have physical properties that depend on the amounts and types of CMC, PEO, and calcium ions to form ioniclaly cross-linked gels. Compositions can be formed into microspheres, coascervates, gels, or membranes. Gels, microspheres and coascervates can be injected directly into a site for dermal filling. Membranes can be surgically introduced, where they swell to form hydrated gels. After introduction, the dermal filler persists for a period of time and then can disintegrate and be removed from the body.

  • Patent number: 6869938
    Abstract: The present invention relates to improved methods for making and using bioadhesive, bioresorbable, anti-adhesion compositions made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then either dried into membranes or sponges, or are used as fluids or microspheres. Bioresorbable, bioadhesive, anti-adhesion compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions. The compositions are designed to breakdown in-vivo, and thus be removed from the body. Membranes are inserted during surgery either dry or optionally after conditioning in aqueous solutions.

  • Publication number: 20020010150
    Abstract: The present invention relates to improved methods for making and using hemostatic, bioadhesive, bioresorbable, anti-adhesion compositions made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, and optionally including multivalent cations and/or polycations and/or hemostatic agents. The polymers can be associated with each other, and are then either dried into membranes or sponges, or are used as fluids, gels, or foams. Hemostatic, bioresorbable, bioadhesive, anti-adhesion compositions are useful in surgery to prevent bleeding and the formation and reformation of post-surgical adhesions. The compositions are designed to breakdown in-vivo, and thus be removed from the body.

  • Patent number: 6193731
    Abstract: A device for inserting a substantially square sheet of flexible material through a laparoscopic cannula into an abdominal cavity. The device is an elongate, generally cylindrical member having a proximal end and a distal end and a body portion therebetween. A pair of tines is rigidly affixed to the distal end of the body portion with a slot separating the tines. A handle is affixed to the proximal end of the body portion. The slot defined between the pair of tines is dimensioned to accommodate the sheet thickness therewithin. In a preferred use, the sheet of material is inserted between the tines with diagonal corners of the sheet within the slot. The free corners of the sheet are drawn together with one hand and the handle of the device is rotated to wrap the sheet around the exterior surface of the two tines.
