ARTHROSCOPIC TISSUE SCAFFOLD DELIVERY DEVICE

摘要

A small diameter delivery device capable of delivering a tissue loaded scaffold arthroscopically to a tissue defect or injury site without reducing the pressure at the injury site is provided. The scaffold delivery device of the present inventi on comprises a plunger system that includes two main components: an insertion tube and an insertion rod. The insertion tube has a flared proximal end for holding a tissue scaffold prior to delivery. An elongate, hollow body extends from the flared proximal end to a distal end of the insertion tube, and defines a passageway that extends through the bod y for delivery of the tissue scaffold. The insertion rod has an elongate body that extends into a handle at a proximal end and a tip at a distal end. The insertion rod is configured to be removably disposed within the insertion tube for sliding along the passagewa y to effect delivery of the tissue scaffold through the insertion tube.
