Publication number: 20100249725Abstract: 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.Type: ApplicationFiled: March 30, 2010Publication date: September 30, 2010Applicant: NP MEDICAL INC.Inventors: Andrew L. Cote, SR., Jake P. Ganem

Patent number: 7789864Abstract: A normally closed valve that may be opened upon insertion of a nozzle permits two-way flow when opened by a luer-taper nozzle. The valve also is able to resist large back pressures. The valve includes a substantially rigid housing that defines a passageway having an inlet section and an outlet section. The housing has an exterior inlet face to which the inlet section opens. The inlet section preferably has tapered and expanding zones. The tapered zone is adjacent to the exterior inlet face and is shaped to receive the nozzle. The expanding zone is adjacent to the tapered zone and has a larger inner diameter than the tapered zone's inner diameter. The exterior of the inlet section of the housing may have threads to accept luer-lock threads that may surround the nozzle.Type: GrantFiled: November 3, 2003Date of Patent: September 7, 2010Assignee: Nypro Inc.Inventors: Andrew L. Cote, Sr., Charles F. Ganem

Patent number: 7753892Abstract: A medical valve has an interior flow path having a volume that is substantially the same when in either the closed mode (when the valve is closed) or the open mode (when the valve is open). To those ends, the medical valve has a housing forming an interior, and a valve mechanism (within the interior) having a substantially rigid translating member with a bore. The interior of the housing has a flow path that includes at least a portion of the bore of the translating member. As noted above, the open mode volume is substantially equal to the closed mode volume.Type: GrantFiled: February 15, 2005Date of Patent: July 13, 2010Assignee: Nypro Inc.Inventors: Brian L. Newton, Andrew L. Cote, Sr., Charles F. Ganem

Publication number: 20080275405Abstract: A medical valve has a resilient member that is forcibly expanded to an expanded volume from a normal volume. Specifically, the valve operates in a closed mode that prevents fluid flow, and an open mode that permits fluid flow. To these ends, the valve has a housing having an inlet and an outlet, and the noted resilient member within the housing. The resilient member and housing form a fluid channel between the inlet and the outlet. The fluid channel at least in part extends through the resilient member. The fluid channel has a given portion formed by a variable volume portion of the resilient member. The variable volume portion has a normal volume when in the closed mode, and an expanded volume when the open mode. The expanded volume is greater than the normal volume.Type: ApplicationFiled: July 2, 2008Publication date: November 6, 2008Applicant: NYPRO INC.Inventors: Brian L. Newton, Andrew L. Cote

Patent number: 7357792Abstract: A medical valve having an open mode to permit fluid flow and a closed mode to prevent fluid flow has a body and a valving element within the interior of the body. The body also has a valving element within its interior, and a proximal port and a distal port. The valving element controls fluid flow between the proximal and distal ports. Moreover, the valving element includes a resilient member and a plug. The resilient member forms a variable sized fluid chamber within the interior of the body, while the plug cooperates with the gland to provide an internal seal (within the interior of the body) that is spaced from the proximal port. The plug is capable of radially expanding the resilient member when the valve transitions from the closed mode to the open mode. The fluid chamber has a larger volume when in the open mode than when in the closed mode.Type: GrantFiled: October 16, 2003Date of Patent: April 15, 2008Assignee: Nypro Inc.Inventors: Brian L.

Patent number: 7014169Abstract: A medical valve has a translating member that enlarges the volume of the interior of the valve when the valve is in an open mode (permitting fluid flow), and decreases the volume of the interior when the valve is in a closed mode (preventing fluid flow). This varying volume should substantially eliminate drawback into the valve. To that end, the valve includes a housing having an inlet and an outlet, and a fluid channel extending between the inlet and the outlet. The fluid channel includes a variable volume region. The valve further includes the above noted translating member, which is secured to the housing and at least partly bounds the variable volume region. The translating member has at least a portion that moves distally when the valve transitions from the closed mode to the open mode. The distal movement of the translating member enlarges the volume on the variable volume region.Type: GrantFiled: May 13, 2004Date of Patent: March 21, 2006Assignee: Nypro Inc.Inventors: Brian L. Newton, Andrew L. Cote, Sr., Charles F. Ganem, Scott Castanon
