Abstract:
1. A closure device deployment device comprising: an elongated housing extending along a longitudinal axis; a sliding member comprising a first portion connected to the inside of the housing, and slidable within the housing between a first position and a second position in the proximal direction along the longitudinal axis upon the application of a first force in the proximal direction, and a second portion extending outside of the housing and along a plane that is perpendicular to the longitudinal axis; a sheath assembly extending along the longitudinal axis comprising a proximal end which is connected to a distal end of said first portion of said sliding member, wherein said sheath is moveable in the proximal direction along the longitudinal axis upon the application of the first force on said sliding member; a rigid wire extending along the longitudinal axis and connected at a proximal end to said housing; a footplate connected to the a distal end of said wire and extending along a plane that is parallel to the longitudinal axis, and structured to be within the distal end of said sheath assembly when the sliding member is in the first position, and outside of the sheath assembly when the sliding member is in the second position; a skin flange extending along the longitudinal axis, connected to the outside of the housing, and slidable in the distal direction along the housing between a first position and a second position; and a skin flange locking feature structured to lock said skin flange in the first position, wherein said sliding member is structured to release said skin flange from said skin flange locking feature per proximal movement of said sliding member allowing said skin flange to slide in the distal direction, wherein a distal end of the skin flange is structured to contact the surface of the skin in the second position, and while the skin flange is in the second position against a patient's skin surface and said footplate is within a patient's blood vessel during use of the closure device deployment device, a predetermined constant proximal force seats the footplate against an inside wall of the blood vessel.
