Patent number: 9604047Abstract: A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. The valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. The variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume that is no less than its closed volume.Type: GrantFiled: August 12, 2013Date of Patent: March 28, 2017Assignee: NP Medical Inc.Inventors: Brian L. Newton, Andrew L. Cote, Sr., Charles F. Ganem, David B. Woyak, Richard T. Boisjoly

Patent number: 8876784Abstract: A medical valve includes a housing having an interior forming an inlet and an outlet. A longitudinally movable member is secured within the interior of the housing. External to the movable member and within the interior is a fluid path. Movement of the movable member controls fluid flow between the inlet and the outlet via the fluid path. The outlet produces no greater than a negligible drawback or positive push during withdrawal of a nozzle.Type: GrantFiled: November 22, 2010Date of Patent: November 4, 2014Assignee: NP Medical Inc.Inventors: Andrew L. Cote, Sr., Brian L. Newton, 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.

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. Newton, Andrew L. Cote, Sr.

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

Patent number: 6892998Abstract: A medical valve has a first housing portion and a second housing portion capable of mating with the first housing portion to form an interior. The medical valve also has a valving element within the interior. The first and second housing portions have mating longitudinal snap-fit structures for longitudinally mating the first housing portion to the second housing portion. The first and second housing portions also have mating rotational snap-fit structures for substantially preventing the first housing portion from rotating relative to the second housing portion when the longitudinal snap fit structures are mated.Type: GrantFiled: October 4, 2002Date of Patent: May 17, 2005Assignee: Nypro, Inc.Inventor: Brian L.

Patent number: 6883778Abstract: A medical valve for valving fluid includes a housing defining a chamber having an inlet, an outlet, and an interior wall, a compressible member within the chamber, and a fluid channel defined by the interior wall. The fluid channel directs fluid received from the inlet toward the outlet.Type: GrantFiled: January 6, 2000Date of Patent: April 26, 2005Assignee: Nypro Inc.Inventors: Brian L. Newton, Charles F.
