(a)(4). Device Description
The RegenBMC® (RegenKit®-THT-BMC-3-10) is for collection of PRP from peripheral blood and bone marrow for improvement of bone graft handling characteristics. The RegenBMC® device uses thixotropic gel medical device vacuum tubes in conjunction with a clinical centrifuge. The RegenBMC® permits the rapid point-of-care preparation of platelet concentrate from either a small volume of the patient's peripheral blood or a mixture of the patient's peripheral blood and bone marrow. Up to 10mL per tube or 30mL per 3 tube kit of peripheral blood or a mixture of peripheral blood and bone marrow is collected from the patient into the medical device tubes and then spun in a centrifuge according to centrifuge operating instructions. The resulting platelet-rich plasma (PRP) is collected with a syringe and can be used to hydrate various bone grafts, such as demineralized cortical and cancellous grafts, for improved handling.
The RegenBMC® kits contain three (3) RegenTHT® 10 ml tubes (Figure 1) which are the main components of the kit. The RegenTHT® 10 ml tubes consist of a sterile pharmaceutical grade glass tube

under vacuum for blood or bone marrow collection. The glass tube contains a thixotropic separator gel (RegenGel-T) composed of a mixture of polymers. (Figure 2). The RegenTHT® 10 ml tubes also contain a sodium citrate anticoagulant solution above the separator gel (Figure 3). The tubes are closed with a bromobutyl stopper.

If processing peripheral blood only, the peripheral blood sample collected from the patient is transferred into all three tubes and centrifuged in an appropriate centrifuge with specific parameters, as detailed in the device's instructions for use. If processing a mixture of peripheral blood + bone marrow, transfer the mixture into all three tubes. Centrifuge in an appropriate centrifuge with specific parameters, as detailed in the device's instructions for use.
After a portion of the plasma supernatant is removed from each tube [i.e. removal of approximately 3.5 mL of platelet-poor plasma (PPP) from each tube], the re-suspension of the cellular sediment into the remaining 2mL of plasma supernatant in each tube is performed by gently inverting the tube at least 20 times. The resulting 6mL (2mL from each of the three tubes) of platelet-rich plasma (PRP), derived from either peripheral blood or a mixture of peripheral blood and bone marrow aspirate is then ready to be collected into a single syringe using a blood transfer device (syringe and transfer device not included in this kit). The PRP preparation is then ready to be used by the physician to be mixed with autograft and/or allograft bone (to hydrate various bone grafts, such as demineralized cortical and cancellous grafts) prior to application to a bony defect for improved handling characteristics. The PRP should be used in this manner by the physician within four (4) hours from the time of the sample collection.
This 510(k) submission includes packaging testing, sterilization validation, shelf-life/stability validation, and biocompatibility testing according to ISO 10993-1 Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process. As an externally communicating – blood path, indirect device with a limited contact duration, the biocompatibility testing included cytotoxicity, sensitization, irritation, acute systemic toxicity, material mediated pyrogenicity and hemocompatibility testing. This evaluation showed the device is non-cytotoxic, non-sensitizing, a non-irritant, no signs of acute systemic toxicity, non-pyrogenic and hemocompatible. Also included is bench testing, which includes blood cell concentration recovery testing, glass tube mechanical testing, bone graft cohesion testing and device equivalency testing, which supports a substantial equivalence determination.

The Arthrex Autologous Conditioned Plasma (ACP) Max™ PRP System (BK210655) is the proposed predicate device. Evidence is provided to show the RegenBMC® is substantially equivalent to the predicate device. Based on the indications for use, technological characteristics, safety and performance testing, the RegenBMC® has been shown to be substantially equivalent to Arthrex ACP Max™ PRP System. The RegenKit®-THT (BK090048) device is also presented as a reference device, considering it has the same design and technological characteristics as the RegenBMC®.
### (a)(5). Indications for Use
The RegenBMC® system is indicated to be used intraoperatively at the point-of-care for the safe and rapid preparation of autologous platelet concentrate platelet-rich plasma (PRP) from a small sample of peripheral blood or a small sample of a mixture of peripheral blood and bone marrow. The PRP is mixed with autograft and/or allograft bone prior to application to a bony defect for improving handling characteristics.
### (a)(6). Technological Characterizes
The RegenBMC® (RK-THT-BMC-3-10) is for collection of PRP from peripheral blood and bone marrow for improvement of bone graft handling characteristics. The RegenKit®-THT-BMC-3-10 permits the rapid point-of-care preparation of platelet concentrate from either a small volume of the patient's blood or a mixture of the patient's blood and bone marrow. The device is design to process up to 10mL per tube or 30mL per 3 tube kit of peripheral blood and/or mixture of peripheral blood and bone marrow which is collected from the patient into the medical device tubes. Peripheral blood or bone marrow is collected from the patient into the medical device tubes and then spun in a centrifuge according to centrifuge operating instructions. The resulting platelet-rich plasma (PRP) is collected with syringes and can be used to hydrate various bone grafts, such as demineralized cortical and cancellous grafts, for improved handling.
The Separator Gel used in RegenBMC® (RegenTHT® tube) is located at the bottom of the tube and remains stable with the following storage conditions: 41°F to 86°F.
Each RegenBMC® tube vacuum is designed to draw approximately 10mL of peripheral blood into each of the three (3) RegenBMC® vacuum tubes. If processing a mixture of peripheral blood and bone marrow, transfer the mixture into all three tubes. Following collection, the peripheral blood or mixture of peripheral blood and bone marrow aspirate is mixed with the anticoagulant by three (3) manual inversions to ensure adequate mixing of the preloaded sodium citrate anticoagulant with the sample. The RegenBMC® tubes are then centrifuged at a relative centrifugal force of 1500g for nine (9) minutes. Following centrifugation, the recovered platelets will be resting on top of the resolidified thixotropic gel layer (with the red blood cells sequestered beneath the gel). The RegenBMC® tube should be gently inverted no less than twenty (20) times, using a "see-saw" motion to resuspend the platelets into the plasma immediately before being transferred into a syringe.
### (b)(1). Substantial Equivalence: - Non-Clinical Evidence Performance Data

{4}
The Arthrex Autologous Conditioned Plasma (ACP) Max™ PRP System (BK210655) is the predicate device. The subject device has the same intended use, similar performance characteristics, and has been evaluated against the same performance standards as the predicate device. The RegenBMC® device is biocompatible per ISO 10993-1.
Platelet-Rich Plasma Bioequivalence Testing Using 30mL of Peripheral Blood and a 30mL Mixture of Peripheral Blood and Bone Marrow showed that PRP produced from the RegenBMC® device is equivalent to the predicate device. The Equivalency Testing evaluated the concentrations of platelets, white blood cells (WBC), red blood cells (RBC), and neutrophils at 0 and 4 hours post collection. The Equivalency testing utilized a 20% margin to evaluate equivalence to predicate device. Testing also confirmed the RegenBMC® device has a pH of at least 5 with at least 50% platelet recovery.
Bone Graft Cohesion Testing was performed using PRP produced by the RegenBMC® device from both Peripheral blood and a combination of peripheral blood and bone marrow. Both PRPs improved bone graft handling characteristics, when compared to a saline control, including the ability of the graft to retain the shape of the syringe mold and hardness and handling properties.
Taken together, the data demonstrate that the RegenBMC® device produces PRP from a mixture of peripheral blood and bone marrow in a manner comparable to the predicate device. Supporting data also demonstrate the ability of the device to process PRP consistent with its intended use and improve bone graft handling characteristics. Observed differences between devices are consistent with known technological characteristics and do not alter the intended use or fundamental performance characteristics of the device, supporting a determination of substantial equivalence.
In addition, the subject device allows for equivalent platelet recovery percentage, when processing blood alone, and a higher platelet recovery percentage, when processing blood and bone marrow together, as compared to the predicate device. While these performance differences exist, there is no impact to the ability of the device to improve bone graft handling characteristics. Therefore, the subject device and the predicate device are substantially equivalent.
In addition, the RegenKit®-THT (BK090048) device is used as a reference device since it has the same components as the RegenBMC® device. The table below shows a comparison of the RegenBMC® device to the predicate and reference device to support substantial equivalence.
