Abstract: An intraluminal grafting system having a delivery catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member and including a graft disposed within the capsule. The graft is comprised of a tubular body configured to be secured to a blood vessel by a self expanding attachment system. The attachment system comprises a generally sinusoidal wire frame having apices which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices and the base apices are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members that are oriented in a responsive relationship to the radially outward bias of the attachment system.

Abstract: A bifurcated graft having a trunk portion and two limb portions, each defined by a docking end and a non-docking end, that is assembled in-situ. The trunk and limb portions are supported by a combination of full and partial stent structures that are connected by longitudinal stent struts to form a continuous stent lattice. The diameters of the docking sections may be standardized such that any limb portion may be inserted into any trunk portion, providing the same degree of mechanical interference for trunk and limb portions having non-docking ends of various diameters.

Abstract: A polymeric material such as polyurethane, PET, or ePTFE is used to cover an intravascular stent. The cover material has an overlapping portion which is slidable upon itself so that when the stent is expanded, the cover material does not contribute to stent foreshortening, if any. The cover material can be provided with holes to permit endothelialization and can be drug loaded to facilitate repair of a damaged vessel.

Abstract: A needle free medical connector includes a housing with a first port and a second port. The connector also includes a piston element defining a fluid passageway between the first and second ports. The piston element is movable between flow and non-flow positions. The piston element has a compressible section having a variable inner width that forms a part of the flow path through the connector. As the piston is compressed to the flow position, the compressible section self-expands in width thereby maintaining or increasing the volume of the fluid passageway through the connector. The compressible section has a configuration permitting the continuous flow of fluid through its entirety.

Abstract: The vasoocclusive coil has a primary coil configuration with a helical loop at at least one end. The terminal helical loop can have a J-shaped configuration, preferably with a loop diameter of about 2 mm. The coil is preferably provided with helical loops at both ends, with helical loop at the proximal and distal ends of the coil acting as an anchor to prevent the coil from coming free from the location being treated and escaping into the vasculature. In a presently preferred embodiment both ends of the coil have a J-shape. In another presently preferred aspect, the vasoocclusive coil includes one or more loops intermediate the ends of the coil. The device is formed from a multi-stranded micro-cable having a plurality of flexible strands of a shape memory material and at least one radiopaque strand.

Abstract: A photo album is provided having an ink-receptive coating on a surface of the photo album. A user may write text or draw pictures on the surface with an ink pen, such as with a gel-based ink pen. The ink-receptive coating protects the ink from smudging or smearing after the ink has dried. Consequently, the text and/or picture is durable. The writable or drawable surface may be the front or back exterior surface, and/or an interior surface.

Abstract: There is provided a microphone apparatus with an adjusting mechanism that prevents wind noise generated at a sound absorbing hole from perceptively inputted in the structure having a microphone built-in at the back of a panel with a sound absorbing hole. A sound box is structured between a sound absorbing hole of a panel and a sound perceptible portion of a microphone, and a movable piece that slidably moves in the sound box is formed. A screw rod is annexed to the movable piece, and a disk screwed with the screw rod is restricted and interposed between a tubular portion, serving as an outer frame of the sound box, and a support portion formed at the lower portion. A part of the disk is exposed to the front surface side from a slit of the panel, and the disk is rotated to move the movable piece, whereby changing a resonant frequency of a ventilation space of the sound box and a ventilation cross.

Abstract: A knee brace is provided with push button actuatable stops, wherein the stops are biased outward into angular locking positions and inwardly directed pressure on the push buttons releases the stops and permits angular adjustment of the stops. A pair of catch plates with locking recesses facing inward, are provided, and outwardly biased locking pins engage the recesses in both catch plates. Each of the stop assemblies has an outwardly directed plate extending over the outer cover plate, and this plate is coupled to the physical stop member around the outer edge of the outer cover plate. The cover plate has angular indicia thereon, which may be viewed through windows in the outwardly extending plate portions of the stop assemblies.

Abstract: A space occupying device for deployment within a patient's stomach and methods of deploying and removing the device. The device includes an expandable member and fasteners, such as sutures, that extend to least partially through the patient's stomach wall, and that anchor the device with the patient's stomach. The device can be deployed and/or removed through transesophageal approaches and/or through a combination of transesophageal and transabdominal approaches.

Abstract: A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness is configured so that the variation of load as a function of expansion through a selected range of expansion is represented generally in the form y=ax+b, and the value of “a” does not increase as the percent expansion increases.

Abstract: An ankle support (100) is constructed using a molded pad (110) and a rigid shell (112). The pad (110) and the shell (112) may be sealed together to form a bladder-pad cushion for comfort. The internal structure of the pad (110) is molded to include geometrically shaped cells of various size, shape and thickness to provide differing levels of localized comfort to the user of the ankle support (100). The pad may be made from a thermoplastic elastomer (TPE) which is spring-like and resists compression sets. The pad may include integrally-molded fingers extending to the shell. The fingers may have different lengths in one or more regions, in order to increase the cushioning effect in a particular region. The pad/shell combination may form a sealed bladder, and a pneumatic pump may be provided in conjunction with the shell so that the user can inflate the bladder.

Abstract: A power controller is positioned within a current path between the line side and the load side of an electrical circuit. The power controller closes the current path in the presence of a control supply and opens the current path in the absence of the control supply. A power supply electrically connected to the current path provides the control supply. A sensor system receives power from the power supply, monitors the current in the current path and outputs a sensor signal indicative of a current condition within the current path. A logic controller also receives power from the power supply, receives the sensor signal and removes the control supply from the power controller when the sensor signal does not satisfy an established criteria. The sensor system may include one or both of an imbalance sensor for monitoring the current balance among two or more electrical lines and over-current sensors for monitoring current in individual lines.

Abstract: A system and method for introducing medical devices within vasculature that incorporates a dual lumen introducer allowing a plurality of guidewires to be introduced without entanglement. The introducer further includes slits formed in the dual lumen introducer and a dilator or an inner member with grooves that facilitate easy removal of the introducer and dilator from vasculature. The dual lumen introducer maintains separation between guidewires. The slits in the dual lumen introducer and the dilator grooves allow removal from the guidewires by slipping the device off the guidewires without retracting them the entire guidewire length. A peel-away sheath protects the vasculature from the guidewires, prevents the dilator from slipping off the guidewires, and maintains access to an expanded vessel for the introduction of medical devices.
