  • Patent number: 10744314
    Abstract: A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet and an outlet, a rigid member movably mounted within the housing, and a resilient member with a sealing portion. The housing also has at least one relief zone that is in fluid communication with the outlet when the valve is in the closed mode. The rigid member may have a proximal end, a distal end, and a flow channel. The relief zone may be radially outward from the sealing portion. The sealing portion may seal the valve and prevent fluid from passing through the valve when in the closed mode.

The inflation valve can include an inflation chamber that is an adequate size to capture a breath of air blown by a user from a distance away from an outside opening of the inflation chamber. This allows surrounding air into the area of low pressure created by the moving air, thereby greatly increasing the amount of air entering the inflatable object. To prevent air from escaping the inflatable object, the inflation valve can include a non-invertible one-way valve and/or an invertible one-way valve. Each valve can prevent air from escaping the inflation chamber until adequate pressure is applied from the outside opening of the inflation chamber, for example, as a result of a user blowing air into the inflation chamber. The invertible one-way valve can be inverted to reverse the properties of the valve.

  • Patent number: 9357910
    Abstract: A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity adapts to tissue tracts of different widths. The surgical instrument includes a proximal member, a distal member, and a sleeve extending between the proximal member and the distal member and defining a longitudinal passage therein. The proximal member includes an inflatable member that selectively adjusts the radial dimension of the proximal member. A ring member may be separately insertable by a user during a surgical procedure into the space directly adjacent to the radially-inner surface of the inflatable member, so as to selectively provide rigidity to the proximal member.

  • Patent number: 9295457
    Abstract: The present invention relates to a balloon catheter system for sealing puncture points or openings in body cavities, hollow organs or in percutaneous drainage operations in mammals, consisting of a filling catheter on the distal end of which a first balloon can be filled with the filling medium is arranged with a further balloon arranged proximally spaced apart therefrom. The balloons close the puncture point or the opening on the two sides in the filled state of the balloon. A hollow needle open at the shaft or the shaft end can be guided in the lumen of the filling catheter for filling the two balloons with the filling medium, wherein the shells of the two balloons enclose the shaft of the filling catheter. The filling catheter in each case has an opening arranged in the balloon lumen to fill the two balloons.

  • Patent number: 9248261
    Abstract: A releasably locking dilator and sheath assembly and methods for releasing the dilator from the sheath and longitudinally splitting the sheath. The assembly includes a dilator having a dilator hub and a sheath having a sheath hub. The sheath hub may have a valve and has two opposing winged tabs, each tab having a perpendicular portion and an angled portion as well as a female threaded portion. The dilator hub has a male threaded portion designed to engage the female threaded portion of the sheath hub. The dilator is released from the sheath by rotating the dilator 90° in relation to the sheath and pulling the dilator out of the sheath. The sheath is longitudinally split by creating a couple on each of the winged tabs thereby forcing the sheath and the sheath hub to split longitudinally. With the sheath and sheath hub split longitudinally, the sheath is removed from around a catheter while leaving the catheter in place.

  • Patent number: 9149625
    Abstract: Embodiments of a catheter insertion device are discussed comprising: an approximately hollow cylindrical catheter sleeve, at whose distal end a catheter is attached; a needle sleeve with a hollow needle, which is attached thereto and which, when ready for use, extends through the catheter sleeve and the catheter, and; a needle protective element that is arranged inside the catheter sleeve while being able to move on the needle. Said needle protective element has an engaging section that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve. A check valve is placed inside the catheter sleeve between the catheter and the needle protective element. The hollow needle, when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.

  • Patent number: 9108032
    Abstract: A valve assembly (10) for controlling a flow of fluid includes a housing (30) having a passageway (33), and a valve sheath (40) disposed interiorly of the housing, at least substantially along the housing passageway. The valve sheath includes a cylindrical valve body (42) having a pair of generally wedge-shaped voids (50A, 52A) formed along opposing longitudinal sides of the valve body. Each of the wedge-shaped voids comprises first and second inwardly-directed sides that converge to define a generally linear edge. The edges are disposed along the valve body in a generally diagonal orientation with respect to a longitudinal axis through the valve body. The respective linear edges are structured and aligned in the valve body to meet along a passageway through the valve body interior in a manner to selectively close the valve body interior passageway, and to yield to permit passage of an interventional device therethrough.
