A coupling device, set to be linked to an interventional delivery system, for coupling and releasing a medical implant, comprising: a generally tubular channel sized and shaped to be conducted in an intravascular catheter; and a pivot extended in and along said generally tubular channel and having a distal end; characterized by: said pivot comprising: a lower plate for applying pushing force on the medical implant, and an upper plate, mounted above said lower plate and having a plurality of grooves for receiving a plurality of anchoring elements of the medical implant so that an anchor of each said anchoring element is, in a resting position: encircled by the generally tubular member; placed in a gap between said lower and upper plates; and temporarily connected to said upper plate, in the resting position, to prevent penetration thereof to surrounding vessels and/or blood vessel walls when in the resting position, and wherein said plurality of anchoring elements are adapted to be released from said gap by retrieving said generally tubular channel while maintaining said pivot in place or pushing said pivot while maintaining said generally tubular channel in place. a generally tubular channel sized and shaped to be conducted in an intravascular catheter; and a pivot extended in and along said generally tubular channel and having a distal end; said pivot comprising: a lower plate for applying pushing force on the medical implant, and an upper plate, mounted above said lower plate and having a plurality of grooves for receiving a plurality of anchoring elements of the medical implant so that an anchor of each said anchoring element is, in a resting position: encircled by the generally tubular member; placed in a gap between said lower and upper plates; and temporarily connected to said upper plate, in the resting position, to prevent penetration thereof to surrounding vessels and/or blood vessel walls when in the resting position, and wherein said plurality of anchoring elements are adapted to be released from said gap by retrieving said generally tubular channel while maintaining said pivot in place or pushing said pivot while maintaining said generally tubular channel in place. a lower plate for applying pushing force on the medical implant, and an upper plate, mounted above said lower plate and having a plurality of grooves for receiving a plurality of anchoring elements of the medical implant so that an anchor of each said anchoring element is, in a resting position: encircled by the generally tubular member; placed in a gap between said lower and upper plates; and temporarily connected to said upper plate, in the resting position, to prevent penetration thereof to surrounding vessels and/or blood vessel walls when in the resting position, and wherein said plurality of anchoring elements are adapted to be released from said gap by retrieving said generally tubular channel while maintaining said pivot in place or pushing said pivot while maintaining said generally tubular channel in place. encircled by the generally tubular member; placed in a gap between said lower and upper plates; and temporarily connected to said upper plate, in the resting position, to prevent penetration thereof to surrounding vessels and/or blood vessel walls when in the resting position, and wherein said plurality of anchoring elements are adapted to be released from said gap by retrieving said generally tubular channel while maintaining said pivot in place or pushing said pivot while maintaining said generally tubular channel in place.
