A retraction system for withdrawing an inner elongated member of an implantation delivery system from a catheter, the retraction system comprising: a first clamp arm comprising a first gripping area ; a second clamp arm comprising a second gripping area ; a shuttle translatable in a proximal direction and a distal direction, on which the first clamp arm and the second clamp arm are mounted; and a slider translatable in the proximal direction and the distal direction, the slider comprising a first contact , wherein a first translation of the slider in the proximal direction translates the first contact proximally to apply a first force from the first contact to the first clamp arm , the first force moving the first clamp arm from an open position to a closed position, wherein, in the open position, the first gripping area and the second gripping area are positioned to allow the inner elongated member of the implantation delivery system to pass through, wherein, in the closed position, the first gripping area and the second gripping area are positioned to engage the inner elongated member, and wherein a second translation of the slider in the proximal direction proximally translates the first clamp arm and the second clamp arm to proximally withdraw the inner elongated member from the catheter of the implantation delivery system while holding the catheter in place, characterized by : a distal mounting block ; a proximal mounting block ; and a rail extending between the distal mounting block and the proximal mounting block , the shuttle and the slider each slidably mounted on the rail . a first clamp arm comprising a first gripping area ; a second clamp arm comprising a second gripping area ; a shuttle translatable in a proximal direction and a distal direction, on which the first clamp arm and the second clamp arm are mounted; and a slider translatable in the proximal direction and the distal direction, the slider comprising a first contact , wherein a first translation of the slider in the proximal direction translates the first contact proximally to apply a first force from the first contact to the first clamp arm , the first force moving the first clamp arm from an open position to a closed position, wherein, in the open position, the first gripping area and the second gripping area are positioned to allow the inner elongated member of the implantation delivery system to pass through, wherein, in the closed position, the first gripping area and the second gripping area are positioned to engage the inner elongated member, and wherein a second translation of the slider in the proximal direction proximally translates the first clamp arm and the second clamp arm to proximally withdraw the inner elongated member from the catheter of the wherein a first translation of the slider in the proximal direction translates the first contact proximally to apply a first force from the first contact to the first clamp arm , the first force moving the first clamp arm from an open position to a closed position, wherein, in the open position, the first gripping area and the second gripping area are positioned to allow the inner elongated member of the implantation delivery system to pass through, wherein, in the closed position, the first gripping area and the second gripping area are positioned to engage the inner elongated member, and wherein a second translation of the slider in the proximal direction proximally translates the first clamp arm and the second clamp arm to proximally withdraw the inner elongated member from the catheter of the implantation delivery system while holding the catheter in place, a distal mounting block ; a proximal mounting block ; and a rail extending between the distal mounting block and the proximal mounting block , the shuttle and the slider each slidably mounted on the rail . <EOS>
