Abstract:
1. A delivery system for delivering an implantable medical device, to a target location of a body vessel, comprising: a generally hollow tubular carrier member having a lumen and a circumference defining a longitudinal axis and having a wall thickness, the carrier member having: an implantable medical device; a locking member that is a tube or wire at least partially received within the carrier member lumen, extending axially within the lumen at least from the proximal portion of the carrier member to the distal portion of the carrier member, and adapted to be mechanically and releasably connected to the implantable medical device; the implantable medical device having a proximal end that has a proximally extending member with a first face and a second face, said faces being oppositely facing, the proximally extending member having an aperture through same and through its first and second faces; the first and second faces of the proximally extending member each being spaced away from the tubular carrier lumen, thereby defining a first open space between the first face and the lumen as well as a second open space between the second face and the lumen; a detachment mechanism having an engaged mode and a disengaged mode, the detachment mechanism includes an engagement member that has an up-turned distal end portion that passes through the first open space, through the aperture and into the second open space during the engaged mode; the up-turned distal end portion of the engagement member has an opening therethrough, and a portion of the locking member is within said opening of the engagement member and within said second open space during the engaged mode whereby the delivery system secures the medical device; a kicker member configured for separating the implantable medical device from the tubular carrier member, wherein the kicker member comprises a first end and a second end, the first and second ends being embedded within the distal end of the tubular carrier member; and a proximal portion of the locking member is fixedly secured to the proximal portion of the carrier member and is fixedly secured to the carrier member proximal portion separated upon breaking of the frangible portion, whereby proximal axial movement of said locking member proximal portion within the lumen results in the disengaged mode and retracts the locking member from the opening of the engagement member of the detachment mechanism and thus disengages the proximal end of the implantable medical device from the delivery system to deliver same to a target location of a body vessel.
