20090030378 | Medical in-line flow control clamp device - A medical in-line flow control clamp device which is arranged coaxially along the longitudinal axis of an infusion tube or the like, and which has a sleeve connected to the tube and a slide having an arm movably mounted on and having a part biased toward the sleeve in a manner where the arm bears against and pinches the tube when the slid is moved relative to the sleeve. The sleeve may have a ramp and support directed toward the tube which causes the arm to move against the tube. The slide may be fabricated from a plastic material, such as acrylic, which causes the arm to bind against the tube. The sleeve may have one or more stops and latch means to receive and secure the arm in tube pinching relation. The sleeve and slide may have a track and projection parts which train the slide in a predetermined direction toward the tube as the slide is moved to pinching position on the sleeve. Bars may be arranged on the slide transverse to the sleeve and tube for manipulating the slide on the sleeve by finger pressure. The sleeve may be fabricated in portions connected by a web so they may be folded and held around the tube in a selected position. | 01-29-2009 |

20090259200 | QUICK RELEASE HEMOSTASIS VALVE - A hemostasis valve apparatus having a quick release apparatus that allows for the exchange of guidewires and other medical instruments into a patient's vasculature while controlling the flow of blood during the exchange. The quick release capability allows tools and instruments to be introduced and removed from the patient's body in a quick and efficient manner without requiring undue attention or manipulation. The quick release capability comprises a lever mechanism which selectively seals or unseals a lumen of the hemostasis valve apparatus. The hemostasis valve apparatus can include a supplemental securement valve assembly which provides a secondary mechanism to secure an instrument positioned in the hemostasis valve and/or control the flow of blood from during the procedure. According to yet another aspect, the quick release mechanism allows for access to the lumen of the hemostasis valve apparatus when the quick release mechanism is in both a released and secured position. | 10-15-2009 |
20090270815 | Catheter Priming System - A catheter includes a longitudinally extending catheter body having proximal and distal ends. The catheter body defines a lumen extending longitudinally from a first port defined at the proximal end, through the body, to a second port defined at the distal end. The catheter includes a valve for controlling fluid flow through the second port. | 10-29-2009 |
20100249724 | Medical Valve with Distal Seal Actuator - A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the valve has a housing with an inlet and an outlet, a post member moveably mounted within the housing and a distal seal member. The post member moves distally within the housing to fluidly connect the inlet and outlet upon insertion of a medical implement into the inlet. The post member also moves proximally within the housing to fluidly disconnect the inlet and outlet upon withdrawal of the medical implement. The distal seal member has a tapered wall region that surrounds a normally closed aperture. The distal movement of the post member opens the aperture and inverts the tapered wall region. | 09-30-2010 |
20100249725 | Medical Valve with Multiple Variable Volume Regions - A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. The valve has a housing, a valve member with a distal seal having a normally closed aperture, a first variable volume region and a second variable volume region longitudinally spaced from the first. Insertion of a medical implement into the inlet opens the aperture and fluidly connects the valve inlet and outlet via a fluid path. Withdrawal of the implement closes the aperture and fluidly disconnects the inlet and outlet. The first variable volume region contracts and the second variable volume expands upon withdrawal of the implement. Both variable volumes may be part of the fluid path. The fluid path may have a closed volume before insertion of the implement and an open volume when in an open mode. The closed volume may be substantially equal to the open mode. | 09-30-2010 |
20110046572 | MEDICAL CONNECTOR - A soft grip medical connector comprises a housing with an upstream end, a downstream end and a lumen extending through a central portion thereof. A flexible member comprises a valve portion integrally formed with a sleeve portion. The valve portion is positioned within a section of the housing and is configured to control a flow of fluid through the housing lumen. The sleeve is inverted to envelope at least a portion of the outer surface of the housing. In some embodiments the gripping portion is integrally formed with the valve portion. In some embodiments, the connector is also generally configured to create a positive pressure in a catheter lumen upon removal of a syringe or other medical device from the upstream end of the connector. Methods of making a medical fluid connector generally comprise forming a valve member with a sleeve extending there from, and assembling the valve, sleeve and housing. | 02-24-2011 |

The pliant valve piston may have an integrally formed plug and one or more ports or a separately formed plug located inside a plastic housing. The plug cooperates with a nozzle on the inlet connector assembly to form a slip port or a Luer inlet, which can open when exerted by force to permit flow or closes when the force is removed. | 09-22-2011 |
