Abstract: A surgical device for performing a repair of lacerated or ruptured tendons is disclosed. The surgical device comprises a tip or first end, a base or second end opposite to the first end, and a length between the first and second end configured to pass at least in part through a tendon sheath. The surgical device increases in diameter from the first end to the second end over at least a portion of the length. The second end is shaped to accommodate retracted proximal end of the damaged tendons. The second end is inserted into a flexor fibro-osseous tunnel configured to distend and enlarge its pathway. The second end is sutured to the retracted proximal end and towed via the fibro-osseous tunnel, thereby providing a gentle, guided, and non-traumatic passage of the flexor tendon and retrieving the retracted proximal end of the damaged flexor tendon simultaneously to the repair zone.
