Patent number: 9724270Abstract: A needle free connector for fluid passage having a valve body with a first port; a second port; a hollow resilient membrane disposed in the valve body and having: a first end and a second end is disclosed. A flank is provided and extends between the first end and the second end fitting with the internal surface of the valve body. A slit of the first end is closed when the first end is disposed in the first port or opened when the first end is pushed into the valve body. The disclosure also proposes a drug recipient including a bottle or a bag designed to store drug and the needle free connector. The disclosure offers a needle free connector with a slitted resilient membrane having reduced priming volume.Type: GrantFiled: August 3, 2012Date of Patent: August 8, 2017Assignee: B.

Patent number: 9314604Abstract: Apparatus enables one or more needleless injection ports to be established on IV tubing as needed. An IV tubing-engaging portion secures the apparatus about the tubing. A puncturing member establishes fluid communication between the IV line and a sealing member on the apparatus. Connecting a syringe to the sealing member establishes fluid communication between the IV line and the syringe, enabling an injection to be made. When the syringe is withdrawn, the sealing member reseals to prevent fluid leakage from the IV line.Type: GrantFiled: July 15, 2010Date of Patent: April 19, 2016Assignee: B. Braun Melsungen AGInventors: Olivier Bonnal, Juergen Fuchs, Andreas Katerkamp, Christian Clobes, Mario Ebert

Publication number: 20150306349Abstract: The valved catheter assemblies described herein provide several advantages, including low cracking pressure for fluid infusion, greater cracking pressure for fluid aspiration, and reduction or elimination of dead space. In some embodiments, a valve of the catheter assembly has a conical shape, which provides different cracking pressures for infusion and aspiration. Also in some embodiments, a valve of the catheter assembly may include peripheral slits that enable fluid to flow around the perimeter of the valve during infusion, which helps to flush out fluid from around the valve.Type: ApplicationFiled: April 28, 2015Publication date: October 29, 2015Inventor: Olivier Bonnal

Patent number: 9072865Abstract: An implantable drainage device for draining the cerebro-spinal fluid of a patient, the device including: a drainage valve including a valve member and a valve seat; a control unit suitable for modifying an operating parameter of said valve, at least as a function of a measurement (D) of the fluid flow rate through said valve; an actuator controlled by the control unit, suitable for modifying the operation of said valve as a function of said operating parameter as modified by the control unit; and a mass flowmeter suitable for evaluating said flow rate of fluid through said valve.Type: GrantFiled: March 13, 2009Date of Patent: July 7, 2015Assignee: SOPHYSAInventors: Philippe Negre, Christophe Moureaux, Christophe Boyer, Olivier Bonnal

Patent number: 8910919Abstract: The various embodiments include a tubular member having an outlet. A sealing member provides a selective seal over the outlet. When the male connector is connected to a female connector, the tubular member establishes fluid communication between the connectors. In certain embodiments, fluid communication between the connectors may be interrupted even while the connectors are still connected. When the male connector is disconnected from the female connector, the sealing member reestablishes a seal over the outlet.Type: GrantFiled: September 3, 2010Date of Patent: December 16, 2014Assignee: B. Braun Melsungen AGInventors: Olivier Bonnal, Juergen Fuchs, Andreas Katerkamp

Patent number: 8177737Abstract: The present invention relates to a drainage device comprising: an internal chamber; at least one inlet port and at least one outlet port communicating with the internal chamber; a shutter disposed at least in part in the internal chamber; at least one first valve seat associated with the inlet port, the shutter being capable of bearing against the first seat in order to isolate the inlet port from the outlet port, in particular when the pressure difference between the inlet and outlet ports is less than a predetermined first opening pressure; and at least one flow constriction associated with the outlet port, the shutter being capable of shutting said constriction, while allowing a minimum, safety flow to pass at a rate that is greater than or equal to 2.5 mL/h even in a maximally-shut position, referred to as a “closed” position, which position is reached in particular for pressure differences between the inlet and outlet ports that are greater than or equal to a predetermined closure pressure.Type: GrantFiled: January 26, 2007Date of Patent: May 15, 2012Assignee: SophysaInventors: Philippe Negre, Olivier Bonnal

Patent number: 6146352Abstract: An implantable drainage valve for the treatment of hydrocephalus includes a housing having an opening at each end and a fluid passageway therebetween, a valve seat within the housing at one end, a closure element dimensioned to be seated in the valve seat, a spring member within the housing secured at the opening opposite the valve seat and a feeder disposed between the closure element and the spring which transmits force from the spring to the closure member. When the housing is in a substantially vertical position, the closure is subjected to a downward force including a force from the spring and the weight of the feeder.Type: GrantFiled: March 24, 1997Date of Patent: November 14, 2000Assignee: Cordis SAInventor: Olivier Bonnal

Patent number: 5718712Abstract: A balloon catheter is provided which includes a flexible tube on one end of which a balloon is mounted to be inflated by means of the tube, which balloon has an annular restriction in its middle region in a plane approximately perpendicular to the tube axis. The balloon is produced in the form of a bag inside which the end of the tube is engaged, the opening of the bag being fixed to the outer wall of the tube, and the distal end of the balloon projects beyond the distal tip of the catheter tube to provide a cushioning region at the tip of the catheter assembly. A procedure for making the balloon is also described.Type: GrantFiled: August 10, 1995Date of Patent: February 17, 1998Assignee: Elekta ABInventors: Olivier Bonnal, Christian Sainte-Rose
