Abstract: An infusion device, including: a housing; an infusion cannula extending downwardly away from the housing and capable of receiving an insertion needle; a septum disposed in the housing; a passageway under said septum and in fluid communication with said cannula; and, an infusion needle insertable through the septum, the infusion needle capable of penetrating the septum and entering said passageway thereby forming a flow path between the infusion needle and the infusion cannula and wherein the ion cannula and the infusion needle are aligned on separate non identical axes.

Abstract: An iris-type valve assembly comprises a base, a rotatable member, and an elongated elastomeric valve sheath. The distal end of the valve sheath is secured to the base, and the proximal end of the valve sheath is secured to the rotatable member. At least one of the valve sheath ends includes a flange that is secured to a valve-receiving surface of the base or the rotatable member. The base and the rotatable member are aligned to define a passageway therethrough for passage of an interventional device. The valve sheath is disposed along the passageway and has a longitudinal opening therethrough for passage of the interventional device. Upon rotation of the rotatable member relative to the base, the longitudinal opening of the valve sheath is selectively constrictable to comprise a seal around the interventional device.

Abstract: Disclosed is a valve/seal assembly that is adapted for use in a variety of applications, such as for example, medical, consumer beverage, pharmaceutical containers, automobile, household appliance and marine. The disclosed valve includes, inter alia, a valve housing having an upper body portion and a lower body portion and a generally spherical valve member. The upper and lower body portions of the housing define an internal chamber for accommodating the valve member and a central axis for the valve. The generally spherical valve member is seated within the internal chamber of the valve housing and has an axial bore extending therethrough. The valve member is mounted for movement between an open position; wherein the axial bore of the valve member is axially aligned with the inlet and outlet ports of the valve housing, and a closed position; wherein the axial bore of the valve member is out of alignment with the inlet and outlet ports of the valve housing.

Abstract: A system for delivery of therapeutic and/or diagnostic agents into a living body includes a port assembly having a cannula extending from the mounting side, a port opening away from the mounting side and a resilient barrier between the port and the cannula. An access hub includes a connector positionable at the port for opening the resilient barrier. The access hub is movable in the port assembly, is engaged therewith through a resilient ring coupling and forms a seal with the resilient barrier, reducing the amount of volume to be primed. Inserters, both disposable and reusable, include the cannula insertion member as part of the assembly. A spring loaded port driver is operatively mounted within the housing with movement controlled by a latch. The driver includes a seat for receipt of a port assembly. The cannula insertion member is nonremovably fixed in a socket in the port driver in the disposable assembly.

Abstract: An infusion device, including: a housing; an infusion cannula extending downwardly away from the housing and capable of receiving an insertion needle; a septum disposed in the housing; a passageway under said septum and in fluid communication with said cannula; and, an infusion needle insertable through the septum, the infusion needle capable of penetrating the septum and entering said passageway thereby forming a flow path between the infusion needle and the infusion cannula and wherein the infusion cannula and the infusion needle are aligned on separate non identical axes.

Abstract: An infusion hub assembly, comprising: a hub received in a hole in a wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon; an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub; a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and a septum positioned in alignment with the bore passing through the cover.

Abstract: According to the invention, the lumen channel, which passes through a guide catheter and an insertion valve, said insertion valve being connected to said guide catheter, is also provided with a shut-off device at a certain point. Said shut-off device enables the lumen to be closed off by means of clamping. In the clamped position, the shut-off device therefore prevents blood from escaping from the insertion valve when it is necessary to open said insertion valve, for example, in order to introduce a treatment catheter.

Abstract: A subcutaneous infusion set for administering a medication or a therapeutic fluid to a patient is disclosed. The infusion set includes a base element having a cavity and an entry lumen. A closing element is mounted on the base element to be rotatable about an axis through the base element and having an aperture, which in one position of the closing element in relation to the base element is aligned with the entry lumen of the base element and in a further rotated position of the closing element in relation to the base element, the closing element covers the entry lumen the base element. A cannula is mounted in and extends from the base element, the cannula having a lumen therethrough, the lumen communicating with the entry lumen through the cavity. Connector means for administering a fluid to the entry lumen are provided.

Abstract: A trocar assembly structured to regulate fluid flow as well as the introduction of predetermined medical instrumentation into and out of a body cavity of a patient during a surgical procedure such as, but not limited to laparoscopy, endoscopy, etc. The trocar assembly includes a housing having a hollow interior secured at one end to an elongated open ended sleeve through which fluid flow and medical instrumentation passes. A valve assembly includes a valve member disposed within the hollow interior and a valve structure including a valve seat rotatably connected to the housing such that the valve seat is selectively rotatable relative to the valve member and into and out of fluid sealing engagement therewith so as to respectively define a valve-closed position and a valve-open position.

Abstract: A large-diameter sheath and assembly for use in introducing a catheter or other medical device into a vessel of the body of a patient. The sheath comprises an elongate sheath tube formed of a flexible material which has proximal and distal extremities and a passage extending therethrough of a predetermined maximum diameter. The sheath tube may either be expandable, with the distal extremity folded longitudinally to a smaller folded diameter, or of a constant diameter. If expandable, the sheath tube may be self-expanding or may be reinforced with a self-expanding wire or expandable stents. A backflow adapter is secured to the proximal extremity of the elongate sheath tube.

Abstract: A permanent or semipermanent hemodialysis access sheath that is placed in a central vein, secured and left in place for easy access by a removable hemodialysis catheter. The hemodialysis catheter has an adapter which secures the catheter to the sheath temporarily permitting the easy removal and replacement of the catheter as needed. The sheath has a side tube with a rotating flush valve. The sheath has a threaded opening which may be engaged by a threaded hub on the hemodialysis catheter for temporaraily securing the catheter to the sheath.
