Abstract:
A device for positioning a resiliently expandable implant within a blood vessel which comprises:a) a tubular sheath for maintaining the implant in a radially compressed configuration, the sheath having a proximal end and a distal end and being open at its distal end and axially moveable relative to the implant,b) a stay positioned within the sheath, proximally of the distal end of the sheath disposed to engage the proximal region of the implant to retain the implant in position as the sheath is withdrawn in a proximal direction, the sheath being axially moveable relative to the stay; andc) an implant retainer adapted to engage the implant, the sheath being axially moveable relative to the retainer and the retainer being stationary relative to the stay, the implant retainer being disposed distally of the stay and being engageable with the proximal portion of the implant to restrain distal movement of the implant in response to relative distal movement of the sheath.
