Abstract:
1. A medial valve, comprising: a housing comprising a first portion having a proximal end including an opening configured to receive a delivery end of a first medical implement, a second portion having a distal end including internal threads and a downwardly extending tube, and an internal cavity, the housing further comprising a first region positioned near the proximal end having a first cross-sectional width, a second region positioned in a distal direction from the first region having a second cross-sectional width, the second cross-sectional width being larger than the first cross-sectional width; a rigid element within the cavity, the rigid element comprising a fluid path and a hole at a tapered proximal end thereof; and a seal element comprising a proximal end, a distal end, an internal cavity, and an external surface comprising a radially outwardly extending portion, wherein an outward portion of the outwardly extending portion is positioned between the first portion of the housing and the second portion of the housing to secure the radially outwardly extending portion with a tight fit, the seal element adapted to move from a first position in which the proximal end of the seal element is positioned adjacent the opening of the housing to a second position in which the proximal end of the seal element is positioned in a distal direction from its location in the first position, the proximal end of the seal element further comprising an orifice extending between an external surface of the seal element and the internal cavity of the seal element, the orifice being in an open position when fluid is permitted to flow through the valve and being in a closed position when fluid is not permitted to flow through the valve; wherein the rigid element is configured to assist in opening the orifice.
