Abstract: A vasoocclusive embolic delivery system for use in placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having its distal end bonded to the distal end of the embolic coil. The stretch resistant fiber extends through a central lumen of the coil and extends beyond the proximal end of the coil. Also included is a generally cylindrical stabilization bead, having a diameter slightly smaller than the diameter of the central lumen of the coil, mounted on the stretch resistant fiber within the lumen of the embolic coil. The stabilization bead serves to keep the stretch resistant fiber centered within the lumen of the embolic coil. Additionally, a headpiece is mounted on the proximal end of the stretch resistant fiber and serves to couple the embolic coil to the delivery system.

Abstract: The present invention has multiple aspects relating to a bone-tendon-bone graft and components thereof. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. Preferred intermediate bone blocks comprise at least one machined segment of cortical bone, cancellous bone or both. Embodiments of intermediate bone blocks of the present invention are used singly or in combination with one or more bone blocks to form a bone block assembly for securing soft tissue. The present invention further relates to an assembled bone-tendon-bone graft suitable for implantation in humans comprising the intermediate bone block and a length of soft tissue. In a preferred embodiment, a bone-tendon-bone graft comprises a length of soft tissue (e.g., tendon) extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block.
