Abstract
A valve assembly including a housing having a base and an outer shell, which forms a proximal cavity and a distal cavity joined by a canal; an inner housing configured for longitudinal movement within the distal cavity; a seal positioned within the distal cavity that together with the longitudinal movement of the inner housing regulates the flow of fluid through the valve assembly; and one or more selected from the group consisting of the base notched with one or more notches and the inner housing having one or more through slots aligned to permit access to the one or more notches, the seal being a reversibly deformable sealing pin, and a torque limiter mechanism configured to resist the longitudinal movement of the inner housing distally until a sufficient radial force is applied.
Claims27
A valve assembly comprising:
- an outer housing comprising a base and an outer shell, which forms a proximal cavity and a distal cavity joined by a canal, wherein the base is threaded at a proximal end and notched with one or more notches at a distal end;
- an inner housing configured for longitudinal movement within the distal cavity, the inner housing comprising one or more through slots aligned to permit access to the one or more notches across the inner housing, and a central boss comprising a through bore that directs passage of fluid through the inner housing;
- and
- a seal positioned within the distal cavity that together with the longitudinal movement of the inner housing regulates the flow of fluid through the valve assembly.
15-17. (canceled)
A valve assembly comprising:
- an outer housing comprising a proximal cavity, a base with one or more notches at a distal end, and a distal cavity joined to the base by a canal;
- an inner housing configured for longitudinal movement within the distal cavity, the inner housing comprising one or more through slots aligned to permit access to the one or more notches, and a central boss comprising a through bore to direct passage of fluid through the inner housing;
- a reversibly deformable sealing pin positioned within the central boss, the sealing pin comprising a proximal base and a distal tip, wherein the sealing pin is configured to deform when applying a sufficient force proximally against the distal tip and substantially reverse deformation upon release of the force, further wherein flow of fluid through the valve assembly is regulated at the proximal base of the sealing pin;
- and
- a removable cap configured to reversibly cap the distal cavity, wherein the cap comprises one or more prongs configured to traverse the one or more through slots to engage the one or more notches so that when capped, rotation of the cap causes rotation of the base.
19-25. (canceled)
A valve assembly comprising:
- an outer housing comprising a proximal cavity and a distal cavity joined by a canal;
- an inner housing configured for longitudinal movement within the distal cavity, the inner housing comprising a central boss comprising a through bore to direct passage of fluid through the inner housing;
- and
- a reversibly deformable sealing pin positioned within the central boss, the sealing pin comprising a proximal base and a distal tip, wherein the sealing pin is configured to deform when applying a sufficient force proximally against the distal tip and substantially reverse deformation upon release of the force, further wherein flow of fluid through the valve assembly is regulated at the proximal base of the sealing pin;
- wherein an open position is defined by the proximal base of the sealing pin spaced apart from both the central boss and the canal.

(canceled)
A valve assembly comprising:
- an outer housing comprising a proximal cavity and a distal cavity joined by a canal;
- an inner housing configured for longitudinal movement within the distal cavity, the inner housing comprising a central boss comprising a throughbore to direct passage of fluid through the inner housing;
- and
- a seal positioned within the distal cavity that together with the longitudinal movement of the inner housing regulates the flow of fluid through the valve assembly;
- wherein the outer housing and inner housing comprise a torque limiter mechanism, configured to resist the longitudinal movement of the inner housing distally until a sufficient radial force is applied, which is greater than a force required to sealingly connect a luer connector to the inner housing.
