Patent number: 8298195Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a resilient piston. The valve includes a valve housing having an inlet port, an outlet port, and an interior cavity with an upper shoulder and a lower shoulder. A resilient piston made of a homogeneous material is positioned within the interior cavity and is compressed by the upper shoulder and the lower shoulder of the valve housing.Type: GrantFiled: October 23, 2007Date of Patent: October 30, 2012Assignee: B. Braun Medical Inc.Inventor: Peter W. Peppel

Patent number: 8100866Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a pliant valve housing interacting with an inlet connector assembly. The pliant valve housing has an integrally formed valve stem and one or more ports. The valve stem cooperates with a nozzle on the inlet connector assembly to form a slip port, which can open when exerted by force to permit flow or closes when the force is removed.Type: GrantFiled: March 24, 2005Date of Patent: January 24, 2012Assignee: B. Braun Medical Inc.Inventor: Peter W. Peppel

Patent number: 7867204Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a stretchable or flexible band. In accordance with aspects of the present invention, the band is held in between a flange section of an inlet connector assembly and a shoulder section of the valve body. A plunger integrally formed with the band is movable inside a nozzle to control fluid flow through the inlet of the valve. When the plunger is urged by a medical implement to open the valve inlet, the band flexes to accommodate the moving plunger.Type: GrantFiled: May 4, 2006Date of Patent: January 11, 2011Assignee: B. Braun Medical Inc.Inventors: Joel Bartholomew, Peter W. Peppel, Michael J. Janders

Patent number: 7615035Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising an inlet coupler. In accordance with aspects of the present invention, a coupler comprises an inlet and an outlet. The inlet is adapted to mate with a first medical implement and the outlet is adapted to mate with an inlet of a valve, which has an outlet adapted to mate with a second medical implement.Type: GrantFiled: March 24, 2005Date of Patent: November 10, 2009Assignee: B. Braun Medical Inc.Inventor: Peter W. Peppel

Publication number: 20090112152Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a resilient piston. The valve includes a valve housing having an inlet port, an outlet port, and an interior cavity. A resilient piston made of a homogeneous material is slidably mounted on a pin and positioned within the interior cavity. The piston is compressed between the pin and the housing.Type: ApplicationFiled: October 26, 2007Publication date: April 30, 2009Inventor: Peter W. Peppel

Patent number: 7510545Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a pliant valve body configured to expand to accommodate a plug when the same is pushed by a syringe or a medical implement and contract when the syringe or medical implement is removed to return the plug to its original position. The plug can move distally and tilt when inside the pliant valve body or remain generally upright when its top surface incorporates flow channels. Interior baffles are included for fluid flow through the interior cavity of the valve. The baffles can vary in shape, number, contour, and can include a ramp.Type: GrantFiled: February 9, 2005Date of Patent: March 31, 2009Assignee: B. Braun Medical Inc.Inventor: Peter W. Peppel

Patent number: 7314061Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising a stretched body. In one aspect of the present invention, a plug is positioned inside a slip port. When the plug is pushed by a medical implement and moves to a second position, the plug abuts the valve body and stretches the valve body. When the medical implement is subsequently removed, the stretched body forces the plug back to its first position.Type: GrantFiled: March 25, 2005Date of Patent: January 1, 2008Assignee: B. Braun Medical Inc.Inventor: Peter W. Peppel

Patent number: 7114701Abstract: Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising a resilient valve body. The resilient valve body includes a tapered set port that stretches when a plug is pushed by a medical implement which in turn pushes the set port. Pushing the plug against the set port opens fluid communication between the inlet port and the outlet port. Upon removal of the medical implement, the resilient valve body pushes the plug back to its closed position.Type: GrantFiled: March 2, 2005Date of Patent: October 3, 2006Assignee: B. Braun Medical, Inc.Inventor: Peter W. Peppel

Patent number: 6871838Abstract: Injection port valves are generally discussed herein and more particularly to port valves that have a valve housing with a nozzle having an inlet opening, a body section, a skirt section, an interior cavity, and a valve seat at an intersection of the first nozzle and the body section in the interior cavity. A piston may be positioned within the interior cavity of the valve housing having a body section having an exterior surface, an upper piston section, a seal surface, and a piston cavity, and wherein the body section includes a wall layer that emits lubricant from within the wall layer to the exterior surface. A nut, which may be a Luer nut, having a flow passage in communication with a discharge nozzle having a discharge lumen may be attached to an end of the skirt section of the valve housing to thereafter connect to an infusion line.Type: GrantFiled: April 3, 2003Date of Patent: March 29, 2005Assignee: B. Braun Medical Inc.Inventors: Kenneth C. Raines, Joel M. Bartholomew, Peter W. Peppel

Patent number: 5730150Abstract: A catheter guidewire dispenser is provided for inserting a guidewire into a blood vessel. The dispenser houses the guidewire in an interior coiled path having spaced apart protrusions which provide friction against the guidewire to retain it within the housing. The device is made from a material with a high coefficient of friction. Single-piece construction prevents disassembly and damage during transit, storage and use. An advancement mechanism having a ribbed surface provides improved feeding control of the guidewire.Type: GrantFiled: January 16, 1996Date of Patent: March 24, 1998Assignee: B. Braun Medical Inc.Inventors: Peter W. Peppel, William J. Reiser
