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.

Systems, devices, and methods for connecting two nerve stumps are provided. A system includes at least one neurorrhaphy device constructed and arranged to engage at least a portion of a proximal nerve stump and a distal nerve stump. The neurorrhaphy device is deployed at one, two, or more deposit sites within a patient, and provides a therapeutic benefit at the deposit site. The neurorrhaphy device allows for the alignment and/or reapproximation the proximal and distal nerve stumps without the application of sutures or other tissue penetrating components within, or in immediate proximity to, the nerve stumps.
