Patent ID: 8257422

Claim:
A detachment mechanism for use in delivering a medical device using a control member over a guidewire comprising: a first engagement member including a tubular body having a lumen about a longitudinal axis and configured to receive said guidewire, the first engagement member having a proximal end attached to said control member, a distal end, and at least two notches formed in the tubular body of the first engagement member proximate the distal end thereof to define at least two interlocking teeth having ring-like structures, the notches of the first engagement member being angled at a first acute angle through the tubular body relative to the longitudinal axis; and a second engagement member including a tubular body having a lumen about a longitudinal axis and configured to receive said guidewire, the second engagement member having a proximal end, a distal end attached to said medical device, and at least two notches formed in the tubular body of the second engagement member to define at least two interlocking teeth having ring-like structures, the notches of the second engagement member being angled at a second acute angle through the tubular body relative to the longitudinal axis, wherein the notches of each of the first and second engagement members is sized to receive the interlocking teeth of the other of the first and second engagement members such that the first and second members are interlockable to couple said control member to said medical device disposed distal thereto, wherein, when coupled, the lumens of the first and second engagement members are in communication with one another such that said guidewire is passable therethrough.
