  • Patent number: 9687332
    Abstract: A method and device for treating hernia by implanting at least one collapsible hernia repair patch, such as a planar mesh body at least partially enveloped by one or more elastic collars. A posterior end of an applicator carrying the repair patch may be inserted through a hernia and into the wall of the abdominal cavity, and the patch may be released into the cavity, e.g., so as to helically deploy the patch such that the patch lies in parallel to the abdominal wall. A balloon, which is removably attached to the patch, may be inflated to help move the patch to a deployed configuration, and thereafter the balloon removed from the hernia site.

  • Patent number: 8298290
    Abstract: An implantable prosthesis for repairing or augmenting anatomical defects, including an inguinal hernia. The prosthesis includes a repair fabric having a body portion and a support member that may be arranged in or on the repair fabric to help deploy the repair fabric at the surgical site and/or help inhibit folding or buckling of the repair fabric. The support member may substantially surround the body portion to help deploy and/or hold the body portion in a spread out configuration for covering the defect. The support member may include first and second ends that are spaced apart to form an interruption so that a slit or keyhole arrangement may be formed in the repair fabric through the interruption and into an interior region of the body portion to receive a body structure, including a cord structure such as the spermatic cord.

  • Patent number: 8172857
    Abstract: An endoscopic tissue apposition device that includes a vacuum chamber configured to securely hold a portion of tissue therein, the vacuum chamber being defined by a proximal wall and a distal wall opposite to the proximal wall. Working and vacuum channels are provided in communication with the vacuum chamber. A portion of tissue is held in the vacuum chamber when vacuum is applied in the vacuum chamber through the vacuum channel. A carrier needle is disposed on a proximal side of the vacuum chamber and is longitudinally advanceable into and across the vacuum chamber, while a punch needle is disposed on a distal side of the vacuum chamber and is configured to receive the carrier needle therein. A hold and release mechanism holds and releases the punch needle to facilitate joining portions of tissue together.

  • Patent number: 7156804
    Abstract: A prosthesis for repairing a tissue or muscle wall defect. The prosthesis comprises a layer of repair fabric having first and second and an edge that extends between the first and second surfaces. The prosthesis also includes a barrier that is inhibits the formation of adhesions with adjacent tissues and organs. The barrier may overlap a portion of the first and second surfaces. The barrier may be formed separate from and attached to the layer of repair fabric to permanently cover a portion of the edge. The repair fabric may be formed from a material which is susceptible to the formation of adhesions with sensitive tissue and organs. The cord protector may be formed from material which inhibits the formation of adhesions with sensitive tissue and organs. The barrier may overlie a portion of at least one of the first and second surfaces of the repair fabric.

  • Patent number: 6669735
    Abstract: A prosthesis is provided for the surgical treatment of hernias. The prosthesis includes two parts, that is, a synthetic non-resorbent mesh and a ring fixed at the peripheral edge of the synthetic mesh. The ring, which is made of a resorbent material, is of a flexibility that permits it to bend, then resume its initial shape to give the mesh a memory of its initial shape. The ring has an interruption intended to be positioned over the femoral veins.

  • Patent number: 5242384
    Abstract: Blood is pumped by a pump, preferably a bi-concave diaphragm pump. When the blood pump is full of blood, this full condition is detected and a batch of blood is emptied completely from the pump for delivery to the patient. A second pump, also preferably a bi-concave diaphragm pump, pumps anti-coagulant into the blood as it is recovered. This second pump ejects its contents every time the blood pump ejects its contents. Particulates in the blood are removed by a filter and air is removed by a defoamer. Fluid and very small matter in the blood may be removed in a tangential flow separator. Blood flows through a narrow passage along one or more membranes, with fluid and small matter passing through the membrane(s). A washing fluid may be added to blood within this separator. A third pump, again preferably a bi-concave diaphragm pump, is used to add this washing fluid. The third pump is emptied whenever the blood pump empties, and thereafter refills with washing fluid.

  • Patent number: 4667662
    Abstract: An orthopedic cerclage device for binding and stabilizing fractured bone segments is formed from an elongate fabric strip adapted to be tied tightly about the bone to secure the fractured bone parts together. The fabric strip has a plurality of transverse ribs raised from one face of the fabric. The strip is wrapped tightly about the bone with the ribbed surface engaging the bone. The strip is secured in place by a locking member. The primary pressure applied to the bone by the device is at the ribs so that the segments of the strip between the ribs do not adversely cut off vascular circulation in the bone. The fabric structure of the device also allows bone tissue to grow into the interstices of the device thereby incorporating it intimately into the healed bone. Also disclosed is a novel knitted fabric in which the ribs are knitted integrally into the stitch pattern of the fabric.

  • Patent number: 4489750
    Abstract: Pulsations are created in a fluid flow stream by a pulsatile device. The device includes a flexible, resilient element which oscillates under the influence of a pressure differential to interrupt the fluid flow at regular intervals, thereby causing the outlet flow to pulsate. The device may be connected directly to a supply of fluid under pressure.
