Abstract:
1. A delivery system for deploying an implantable medical member to a target site within the body of a patient, comprising: an elongated dilator having a proximal portion, a distal portion, and a passageway extending therebetween, said proximal portion including at least one tab extending from a proximal end thereof, said distal portion tapering to a distal tip, said distal portion being splittable to facilitate delivery of said implantable medical member to said target site; an introducer having a proximal portion and a distal portion, said proximal portion extending to a proximal end and said distal portion extending to a distal end, said introducer distal portion received in said dilator passageway and extending substantially along a length of said dilator to said tapered distal portion, said introducer structured and arranged relative to said dilator such that upon a proximal movement of said dilator relative to said introducer, said tapered distal tip of said dilator splits whereby said introducer distal portion extends through said split dilator portion, said introducer proximal end extending beyond said dilator proximal portion in a proximal direction, said introducer being dimensioned for receiving said implantable member therein; and a handle mechanism arranged to receive said proximal portion of said dilator, said handle mechanism including a respective gripping mechanism engaged with each of said at least one tab for initiating said proximal movement of said dilator relative to said introducer upon a rotation of said gripping mechanism, and an activator engaged with said gripping mechanism for initiating said rotation of said gripping mechanism, wherein said handle includes a clamp member for releasably receiving said proximal portion of said introducer, wherein said at least one tab comprises a pair of tabs and said handle mechanism comprises a pair of gripping mechanisms, each of said gripping mechanisms engaged with a respective one of said tabs, wherein said at least one tab comprises a pair of tabs and said handle mechanism comprises a pair of gripping mechanisms, each of said gripping mechanisms engaged with a respective one of said tabs, wherein said handle mechanism further comprises an elongated nose portion arranged therealong, said nose portion including a distally tapered portion structured and arranged to receive said dilator proximal portion upon said proximal movement, and configured such that said dilator proximal portion splits upon movement thereover, wherein said activator comprises a trigger member movably engaged with said nose portion, wherein said handle further comprises a biasing member for moving said dilator in a distal direction upon a release of said activator.
