A repaired tendon includes a proximal tendon section having a free end, and a distal tendon section having a free end that opposes the free end of the proximal tendon section. Four bidirectional barbed sutures are implanted in the repaired tendon for approximating the free end of the proximal tendon section with the free end of the distal tendon section. Each of the four bidirectional barbed sutures includes a proximal section having proximal barbs that engage the proximal tendon section, a distal section having distal barbs that engage the distal tendon section, and a stop located between the proximal and distal barbs that engages the approximated free ends of the proximal and distal tendon sections. The bidirectional barbed sutures have first suture bites and second suture bites that are shorter than the first suture bites.

A needle camera adaptor includes a tube-shaped body having a proximal end, a distal end, a longitudinal axis, and a lumen that extends along the longitudinal axis. A centrally-located lateral access opening is formed in an outer wall of the tube-shaped body. A needle securing channel is formed in the outer wall and extends between the lateral access opening and the distal end of the tube-shaped body. A curved suture needle is disposed within the needle securing channel. The needle securing channel and the curved suture needle extend along an axis that defines an oblique angle with the longitudinal axis of the needle camera adaptor. A visualization device, facing distally, is positioned within the lumen at the proximal end of the tube-shaped body. The lateral access opening, the needle securing channel, and the curved suture needle are located within a field of view of the visualization device.

An elastic suture needle for passing through a smaller cannula used in minimally invasive surgery includes an elongated body having a proximal end, a distal end, a length extending from the proximal end to the distal end, a top surface extending along the length of the elongated body, and a bottom surface extending along the length of the elongated body. The elongated body has dimensions that are calculated using the equation T/L&#x3c;(4*&#x3c3;)/(&#x3c0;E), where T is the thickness of the elongated body, Lis the length of the neutral axis of the elongated body, &#x3c3; is the yield strength of the elongated body, and E is the Young's modulus of the elongated body. The elongated body is made of stainless steels such as martensitic stainless steels, austenitic stainless steels, martensitic-aged (mar-aged) stainless steels, and stainless steels sold under the registered trademark ETHALLOY&#xae; Needle Alloy.

Novel apparatus and methods for coating surgical needles in batch processes are disclosed. The apparatus and methods are particularly useful for applying uniform silicone lubricious coatings to surgical needles in bulk quantities using a novel separation and spray coating system and method.

A needle and suture assembly includes a needle made of a superelastic alloy, such as Nitinol, including an elongated body having a proximal end and a distal end with a sharpened tip, a suture having a free end juxtaposed with the proximal end of the elongated body of the needle, and a connector disposed between the needle and the suture. The connector includes a first end attached to the proximal end of the elongated body of the needle and a second end attached to the free end of the suture. The connector is made of a material, such as stainless steel, having less elasticity and greater plasticity than the superelastic alloy of the needle.

A needle sheath includes a tubular shaft having a chamfered edge at a distal end thereof. A stop flange is secured to a proximal end of the tubular shaft. A needle relief slot is formed in a bottom side of the tubular shaft. The needle relief slot has a length that extends along an axis that is parallel to the longitudinal axis of the tubular shaft. A needle point slot formed in a top side of the tubular shaft. The needle point slot has a length that extends along an axis that is perpendicular to both the longitudinal axis of the tubular shaft and the needle relief slot axis. A suture needle is disposed within the tubular shaft of the needle sheath. The suture needle has a curved body that passes through the needle relief slot and a needle point captured within the needle point slot.

A swaging system for attaching surgical needles to sutures and testing the attachment strength includes a frame, a bottom swaging die mounted on the frame, and a top swaging die mounted on the frame and being moveable up and down along a swaging axis that is aligned with the bottom swaging die. The bottom swaging die includes a hinge mechanism with a bottom plate mounted to the frame and a top plate overlying the bottom plate. The top and bottom plates are pivotally connected for enabling the top plate to pivot relative to the bottom plate. The bottom swaging die includes a swaging tool that extends toward the top swaging die along the swaging axis, and a load cell disposed between the top and bottom plates for monitoring load. The system includes a control system having one or more pull test programs stored therein for conducting pull tests on armed surgical needles to determine if the armed surgical needles are acceptable or unacceptable.

A swaging system for attaching surgical needles to sutures and testing the attachment strength includes a bottom swaging die and a top swaging die that is configured to move up and down along a swaging axis that is in alignment with the bottom swaging die. The bottom swaging die includes a swaging tool mounted thereon that extends toward the top swaging die along the swaging axis. The swaging tool includes an upper end having a top surface with a swaging notch for swaging a needle to a suture to form an armed surgical needle, and a testing notch, adjacent the swaging notch, for conducting a pull test on the armed surgical needle.
