Angel® cPRP System Operator’s Manual

Before You Get Started

Before You Get Started Introduction The Angel® Concentrated Platelet Rich Plasma (cPRP) System (Angel System) is designed to separate autologous blood or a mixture of blood and bone marrow and collect plasma rich in platelets preoperative to a surgical procedure. The primary blood components that the Angel System separates and collects are red blood cells (RBC), platelet poor plasma (PPP) and platelet rich plasma (PRP). At the end of the separation process, the components are ready for reinfusion. The Angel System utilizes a Variable Volume Separation Chamber that is capable of processing between 40 mL to 180 mL of anticoagulated whole blood or mixture of blood and bone marrow in a single cycle. A maximum of 540 mL can be processed in up to three (3) cycles for each disposable Angel® Concentrated Platelet Rich Plasma (cPRP) System Processing Set (Angel Processing Set or Disposable Set). This manual is intended for users of the Angel System. The procedures recommended in this Operator’s Manual have been developed and tested to provide safe, reliable and efficient operation of the Angel System. It is important that the operator thoroughly understand the information in this Operator’s Manual before attempting to use the Angel System.

Indications for Use The Angel System is intended to separate and collect an autologous plasma fraction rich in platelets and red blood cells from the patient’s whole blood or a small mixture of blood and bone marrow perioperative to a surgical procedure.

Contraindications for Use The Angel System is not intended to wash blood salvaged from the surgical site, nor is it intended for direct connection to the patient. The risk/benefit ratio of autologous sequestration must be determined on a case by case basis by the qualified medical personnel in charge of the patient’s care; the responsibility for the use of this device belongs solely to the physician in charge.

Angel® cPRP System Operator’s Manual

Overview

Chapter 1: Overview Product Description The Angel® Concentrated Platelet Rich Plasma (cPRP) System (Angel System) consists of a blood processing system and disposable products used for preoperative sequestration for whole blood or a mixture of blood and bone marrow into red cells, platelet poor plasma, and platelet rich plasma. The disposable Angel® Concentrated Platelet Rich Plasma (cPRP) System Processing Set (Angel Processing Set or Disposable Set) is designed for single-patient use. The Variable Volume Separation Chamber allows the clinician to process from 40 mL to 180 mL of autologous whole blood or a mixture of blood and bone marrow in a single cycle. A maximum of 540 mL can be processed in up to three (3) cycles for each disposable Angel Processing Set.

Description of the Angel® Concentrated Platelet Rich Plasma (cPRP) System How the Angel® Concentrated Platelet Rich Plasma (cPRP) System Works The Angel System processes a determined volume of anticoagulated whole blood or a mixture of blood and bone marrow from a patient and separates the blood/bone marrow into its primary components: red blood cells (RBC), platelet poor plasma (PPP), and platelet rich plasma (PRP). The basic steps are: Blood Collection: The whole blood or a mixture of blood and bone marrow is drawn from a patient and mixed with a citrate anticoagulant. The collected whole blood/bone marrow is mixed in a 7:1 ratio (7 parts whole blood to 1 part citrate anticoagulant (ACD-A)). Please refer to the Instructions for Use for the Angel® Concentrated Platelet Rich Plasma (cPRP) Processing Set for details regarding Blood Collection. Processing: The Angel Processing Set utilizes a Variable Volume Separation Chamber (40 mL to 180 mL) which allows the clinician to determine the amount of preoperative blood/bone marrow volume to be processed. Each Angel Processing Set can be used for up to three processing cycles. Once the anticoagulated whole blood or mixture of blood and bone marrow has been dispensed into the Whole Blood Compartment of the reservoir bag, the clinician selects the desired volume of autologous whole blood/bone marrow to process and presses the “Start” Button on the Touch Screen Display. The Angel System will fill the Variable Volume Separation Chamber with the pre-determined volume of anticoagulated whole blood or a mixture of blood and bone marrow, separate the whole blood/bone marrow through centrifugation, and collect the primary blood components (RBC, PPP, and PRP) in their respective collection compartments. Administration: Reinfusion of blood components is under the control and supervision of the physician in charge. Follow your institution’s blood administration protocol for appropriate handling and labeling of blood components. Angel® cPRP System Operator’s Manual
