The HVR 4000 Nonfiltered is intended for storage of blood during surgical procedures on adults requiring extracorporeal circulation for periods of up to six hours. ## Device Story HVR 4000 Hardshell Venous Reservoir (Filtered/Nonfiltered) functions as open cardiopulmonary bypass blood reservoir; provides blood storage and cardiotomy filtration during adult surgical procedures requiring extracorporeal circulation. Device receives venous blood input; utilizes knitted polyester fabric defoamer; filtered version incorporates polyurethane foam for gross filtration and polyester depth media for fine filtration. Operated by perfusionists/surgical staff in clinical settings. Output provides managed blood volume for extracorporeal circuit; supports clinical decision-making by maintaining hemodynamic stability during bypass. Benefits include effective blood storage and filtration, reducing potential for blood trauma and debris circulation. ## Clinical Evidence No clinical testing was performed. Safety and efficacy were established via in vitro bench testing, including blood trauma characteristics, filtration efficiency, and volume capacity verification. Material biocompatibility, sterilization, and packaging requirements were met. ## Technological Characteristics Hardshell venous reservoir; materials include knitted polyester fabric (defoamer), polyurethane foam (gross filtration), and polyester depth media (fine filtration). Features one-piece molded venous inlet port. Sterilized by ethylene oxide gas. Nonpyrogenic fluid pathways. Open cover design for venting. ## Regulatory Identification A cardiopulmonary bypass blood reservoir is a device used in conjunction with short-term extracorporeal circulation devices to hold a reserve supply of blood in the bypass circulation. ## Special Controls *Classification.* Class II (special controls), except that a reservoir that contains a defoamer or filter is classified into the same class as the defoamer or filter. The device, when it is a cardiopulmonary bypass blood reservoir that does not contain defoamers or blood filters, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9. ## Predicate Devices - Maxima Hardshell Venous Reservoir - Top Entry, Model MHR-T ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Armstrong Phone:(303) 467-6521 Fax: 5/5/97 DATE PREPARED: COBE® HVR™ 4000 Filtered Hardshell Venous Reservoir DEVICE TRADE NAME: COBE® HVR™ 4000 Nonfiltered Hardshell Venous Reservoir - Hardshell venous reservoir with integral cardiotomy filter COMMON NAME: Hardshell venous reservoir - CLASSIFICATION NAME: Cardiopulmonary bypass blood reservoir with defoamer and cardiotomy suction filter Cardiopulmonary bypass blood reservoir with defoamer PREDICATE DEVICE: Maxima Hardshell Venous Reservoir - Top Entry, Model MHR-T DEVICE DESCRIPTION: The HVR™ 4000 Filtered Hardshell Venous Reservoir is an open cardiopulmonary bypass blood reservoir with defoamer and cardiotomy suction filter. Used in coniunction with other ancillary equipment and disposable products, this device will satisfy an adult patient's blood storage and cardiotomy filtration requirements during surgical procedures. The HVR™ 4000 Nonfiltered Hardshell Venous Reservoir is an open cardiopulmonary bypass blood reservoir with defoamer. Used in conjunction with other ancillary equipment and disposable products, this device will satisfy an adult patient's blood storage requirements during surgical procedures The product is sterilized by ethylene oxide gas and has nonpyrogenic fluid pathways. INDICATIONS FOR USE: The HVR 4000 Filtered is intended for storage and filtration of blood during surgical procedures on adults requiring extracorporeal circulation for periods of up to six hours. The HVR 4000 Nonfiltered is intended for storage of blood during surgical procedures on adults requiring extracorporeal circulation for periods of up to six hours. TECHNOLOGICAL CHARACTERISTICS: Comparing the HVR™ 4000 Filtered Hardshell Venous Reservoir and the HVR™ 4000 Nonfiltered Hardshell Venous Reservoir with the Maxima Hardshell Venous Reservoir, some similarities and differences are noted in the design and technology employed to accomplish their intended uses. {1}------------------------------------------------ #### 510(k) Premarket Notification All three devices use a knitted polyester fabric as the outer defoamer covering. In the filtered devices (i.e., the HVR 4000 Filtered and the Maxima Hardshell Venous Reservoir), filtration is accomplished through use of polyurethane foam for gross filtration and polyester depth media for fine filtration. All three devices include the same functional types of porting in essentially the same numbers and sizes. For venting, the Maxima Hardshell Venous Reservoir uses a port on its cover where the COBE HVR 4000 Hardshell Venous Reservoirs use an open cover design. Both COBE devices use a one-piece, molded venous inlet port, whereas the Maxima device uses a two-piece inlet comprised of a rigid, injection molded port joined to a flexible, polyvinylchloride tube. NONCLINICAL TEST RESULTS: The blood trauma characteristics of the HVR 4000 Filtered and the HVR 4000 Nonfiltered are not significantly different compared to the Maxima Hardshell Venous Reservoir. Filtration efficiency of the HVR 4000 Filtered meets specification. Volume capacity of both COBE devices meet specification. Material biocompatibility, sterilization and packaging of both COBE devices meet requirements. All labeling claims have been substantiated. The COBE HVR 4000 Hardshell Venous Reservoirs will be labeled with a one year expiration period. CLINICAL TEST RESULTS: No clinical testing was performed. Safety and efficacy were determined by in vitro testing. CONCLUSIONS: - 1. The COBE devices' blood trauma characteristics are comparable to those of the predicate device. - 2. The COBE devices' maximum operating volumes meet claims - 3. The COBE devices' minimum operating volumes meet claims - The COBE devices' filtration efficiency meets claims 4. - 5. Material biocompatibility, sterilization and packaging for the COBE devices meet requirements - 6.
