    摘要： A hernia repair prosthesis with an occlusive member for inserting into and/or backing the herniated tissue. The occlusive member is convertible from a first configuration with a first axial length and first major radial extent to a second configuration with a second axial length and a second major radial extent. The second axial length is less than the first axial length and the second major radial extent is larger than the first major radial extent. The occlusive member has a pair of subsections, each having an apex, lands and pleats and each flaring outwardly therefrom towards a terminal end. The apexes are disposed at opposite ends of the occlusive member with the terminal ends overlapping. The pair of subsections are conjoined proximate the overlapping terminal ends. The terminal end of one or both of the subsections may be in the form of a conic flange mimicking the lands and pleats of the other subsection providing automatic alignment and nesting to aid in the attachment of the two subsections. In accordance with methods for forming the subsections, a surgical fabric is thermoset on a male die and may be stretched or heat shrunk to aid in conforming the surgical fabric to the contours of the male die. The subsections may be joined by ultrasound.

    摘要： A prosthesis for treating a body passage includes a micro-porous tubular element and a support element. The tubular element is formed from a thin-walled sheet having a wall thickness of 25 micrometers or less, preferably a coiled-sheet exhibiting temperature-activated shape memory properties. The mesh pattern includes a plurality of openings in the sheet having a maximum dimension of not more than about 200 micrometers, thereby acting as a filter trapping embolic material while facilitating endothelial growth therethrough. The support element includes a plurality of struts, preferably having a thickness of 100-150 micrometers. The support element is preferably an independent component from the tubular element. Alternatively, the support element may be attached to or integrally formed as part of the tubular element. The tubular and support elements are placed on a catheter in contracted conditions and advanced endoluminally to a treatment location within a body passage. The tubular element is deployed, and the support element is expanded to an enlarged condition at the treatment location to engage an interior surface of the tubular element, thereby securing the tubular element and holding the lumen of the treatment location open.

    摘要： Continuous internal peritoneal dialysis prosthesis and method employing an abdominal sac adapted to be retained in the abdominal region of a patient's body and including dialyzate therein for permitting unconcentrated urine within the peritoneal region to pass through a semi-permeable membrane wall of the abdominal sac. The unconcentrated urine within the abdominal sac is directed through a section of the patient's bowel and is communicated with the internal wall of the bowel to thereby concentrate the urine. The concentrated urine is then directed into the urinary bladder for subsequent excretion from the patient's body. In the preferred prosthesis and method of this invention the normal breathing pattern of the patient is employed to assist in the circulation of the unconcentrated urine from the abdominal sac into and through the section of the patient's bowel. In alternative embodiments, the dialyzate may be contained within the abdominal sac, contained within the prosthesis, or allowed to directly contact the peritoneum.

    摘要： An implantable esophageal sphincter apparatus with an adjustable band to be placed at the lower part of the esophagus. The inflation of the band, or sphincter body, can be increased or decreased to adjust the tightness of the device. The inflatable sphincter body may be wrapped around the esophagus and may be connected to an inflation device with a fluid reservoir. The inflation device may have a pump mechanism that will respond to external control to increase or decrease the inflation of the sphincter body. The sphincter apparatus will be held in place at the area of implantation by sutures and by fenestration mechanisms, which will allow ingrowths of tissue or fibrous elements of the body around the sphincter apparatus or into porous materials on the sphincter apparatus. The apparatus may also include a circumferential shield on a distal side of the sphincter apparatus. The shield is adapted to fit against the distal or lower side of the patient's diaphragm and inhibits the development of a hiatus hernia, that is, a protrusion of the stomach past the diaphragm through the passage for the esophagus.

    摘要： A lung-assist apparatus includes a tubular housing, a tubular nozzle therein, and a first valve disposed between the housing and nozzle. The housing is implanted across a bifurcation such that the nozzle extends from a first branch communicating with a healthy region of a lung towards a main passage, and terminates proximate a lateral opening in the housing that is disposed within a second branch communicating with a damaged region of the lung. During inhalation, the first valve opens to allow air flow into the first branch, and closes during exhalation to force air through the nozzle, thereby inducing a vacuum for drawing air from the damaged region. A second valve in the second branch opens during exhalation to draw air from the diseased region, and closes during inhalation to prevent air from being drawn into the damaged region.

    摘要： A ureteral device is provided for facilitating stone passage through a ureter or duct. An exemplary ureteral device includes a flexible, elongate body that defines a plurality of cages along the body. In a contracted state the cages have a reduced diameter. When an activation force is applied, the cages transform to an expanded state, thereby defining a plurality of void spaces. The void spaces are configured to receive an obstruction, such as a stone. The ureteral device can then be induced to the contracted state to compress the obstruction within the elongate, flexible body and then be removed from the obstructed passage. The ureteral device can be configured to have different numbers of elongate flexible members that define the cages.
