Device Description
This 510(k) notification advises FDA of minor changes to implant specifications, revisions and additions to the class 1 instruments, and an extension of shelf life to three years per the original validation plan presented in K200725.
The subject bone anchor devices are comprised of Citregen biomaterial, which is a homogeneous biocomposite comprised of 60 wt.-% unsintered hydroxyapatite (HA) and 40 wt.-% polyester. Citregen's polymer component is a citrate-based network of completely amorphous polymer chains crosslinked together to form an elastomeric material. As water penetrates the subject device, surface erosion of the polymer phase occurs through hydrolysis of the ester bonds located between the monomers and at the crosslink sites.
The Citregen Tendon Interference Screw and Citrelock are fixation devices ranging in diameter from 4 to 9 mm and lengths from 10 to 23 mm. There are two designs; 1) a traditional tapered, blunt threaded and cannulated screw that is screwed into the prepared bone and 2) a "twist-ribbed" cannulated, self-locking device (trade named Citrelock) that is inserted into bone. Citregen Tendon Interference Screw and Citrelock implants attach soft tissue to bone for surgical procedures in the foot/ankle, knee, shoulder, elbow, and hand/wrist. The updates to the class 1 manual instruments include minor design modifications and new reusable instruments, single-use and sterile instruments that are packaged together with an implant in a "kit" configuration and new single-use and sterile instruments to facilitate surgery.
The Citrefix is a suture anchor offered in diameters between 2.9 and 5.5 mm and lengths ranging between 12.5 and 24.0 mm, and includes an integral eyelet made of PEEK that facilitates passage of suture through the tip of the anchor. The Citrefix is implanted with reusable instruments that include size specific drills and awls for preparing the bone, and an insertion instrument for placement of the Citrefix device. Suture is not provided with the Citrefix device.
The Citrespline ACL and Citrelock ACL are bone anchor devices ranging in diameter from 7 to 12 mm in 1 mm increments, and lengths of 23, 28, and 33 mm. There are two designs for the system: 1) "twist-ribbed" cannulated, self-locking devices (Citrelock ACL) and 2) a "straight spline" style device (Citrespline ACL). Both designs have a cannula through the central axis for alignment into the surgically prepared site. Surgical placement is facilitated with a reusable set of instruments.

E. Device Descriptions
This 510(k) notification advises FDA of minor changes to implant specifications, revisions and additions to the class 1 instruments, and an extension of shelf life to three years per the original validation plan presented in K200725.
The subject bone anchor devices are comprised of Citregen biomaterial, which is a homogeneous biocomposite comprised of 60 wt.-% unsintered hydroxyapatite (HA) and 40 wt.-% polyester. Citregen's polymer component is a citrate-based network of completely amorphous polymer chains crosslinked together to form an elastomeric material. As water penetrates the subject device, surface erosion of the polymer phase occurs through hydrolysis of the ester bonds located between the monomers and at the crosslink sites. The following paragraphs describe the subject devices.
8
The Citregen Tendon Interference Screw and Citrelock are fixation devices ranqing in diameter from 4 to 9 mm and lengths from 10 to 23 mm. There are two designs; 1) a traditional tapered, blunt threaded and cannulated screw that is screwed into the prepared bone and 2) a "twist-ribbed" cannulated, self-locking device (trade named Citrelock) that is inserted into bone. Citregen Tendon Interference Screw and Citrelock implants attach soft tissue to bone for surgical procedures in the foot/ankle, knee, shoulder, elbow, and hand/wrist. The updates to the class 1 manual instruments include minor design modifications and new reusable instruments, single-use and sterile instruments that are packaged together with an implant in a "kit" configuration and new single-use and sterile instruments to facilitate surgery.
The Citrefix is a suture anchor offered in diameters between 2.9 and 5.5 mm and lengths ranging between 12.5 and 24.0 mm, and includes an integral eyelet made of PEEK that facilitates passage of suture through the tip of the anchor. The Citrefix is implanted with reusable instruments that include size specific drills and awls for preparing the bone, and an insertion instrument for placement of the Citrefix device. Suture is not provided with the Citrefix device.
The Citrespline ACL and Citrelock ACL are bone anchor devices ranging in diameter from 7 to 12 mm in 1 mm increments, and lengths of 23, 28, and 33 mm. There are two designs for the system: 1) "twist-ribbed" cannulated, self-locking devices (Citrelock ACL) and 2) a "straight spline" style device (Citrespline ACL). Both designs have a cannula through the central axis for alignment into the surgically prepared site. Surgical placement is facilitated with a reusable set of instruments.
F. Comparison of Technological Characteristics
Acuitive Technologies subject devices and predicate implant devices (K200725, K203334. K210239) are identical in indications and intended use, size options. surgical technique, and materials. The changes made to the predicate devices include minor modifications to the tolerances of the implants and modification and addition of class 1 reusable instruments and sterile single-use instrument kits (Citrelock Xpress Instrument Kit and Citregen Tendon Sizing Kit) for the system described in K200725. The Citrelock Xpress Implant Kit includes a sterile Citrelock implant packaged together with a single use, Citrelock Xpress Instrument Kit. Engineering assessment of the updated reusable instruments and validation of performance, sterility and packaging integrity of the Citrelock Xpress Instrument Kit and Citregen Tendon Sizing Kit instruments demonstrated that the subject and predicate device instruments possess the same technological characteristics and the instruments that are provided sterile have a shelf life of 3 years.
G. Performance Data
The biocompatibility and ability to clean and sterilize the reusable instrument set was verified and validated per ISO 10993-1 and AAMI TIR30. AAMI TIR12. ISO 17664, ISO 17665, AAMI ST79, and EN 556-1.
9
The packaging, sterilization, shelf life, and biocompatibility of the single-use Citrelock Xpress Instrument Kit and Citregen Tendon Sizing Kit were validated per ISO 11137-1 and -2, ISO 11607-1 and -2, ASTM F1980, ASTM D4169, and ISO 10993-1. The subject devices have been validated for 3-years shelf life, real-time.
H. Conclusion
The minor changes to the specification of the implants, the modifications and additions to the reusable instruments, the addition of single use instruments and increased shelf-life for the subject devices do not raise new issues of safety or effectiveness. The information presented in this 510(k) notification demonstrates substantial equivalence of the subject and predicate devices.
