The integral heat exchanger is used to warm or cool blood and/or perfusion fluid as it flows through the device. The (detachable) hardshell reservoir is used to store blood during extra-corporeal circulation from both venous line and the cardiotomy line (via gravity or vacuum assisted venous drainage procedures). The venous section of the reservoir contains a filter to remove particulate matter and a defoamer to facilitate air bubble removal. The cardiotomy section of the reservoir contains a filter to remove particulate matter and a defoamer to facilitate air bubble removal. The Reservoir may also be used for Post-Operative Chest Drainage procedures. The CAPIOX® RX25 Oxygenator with/without Hardshell Reservoir can be used in procedures lasting up to 6 hours. The CAPIOX® RX25 is for use with patients when the required blood flow rate will not exceed 7.0 l/min. ## Device Story Device is a hollow fiber oxygenator with integrated heat exchanger and detachable hardshell reservoir; used in cardiopulmonary bypass surgery. Inputs: venous blood and cardiotomy suction blood collected via gravity or vacuum. Operation: blood passes through reservoir filters/defoamers to remove air/particulates; flows through heat exchanger for temperature regulation; enters oxygenator module where gas transfer (O2/CO2 exchange) occurs via diffusion across hollow fiber membranes. Output: oxygenated, temperature-controlled blood returned to patient. Used in OR by perfusionists/surgeons. Benefits: provides life-sustaining gas exchange and temperature control during cardiac procedures. Features X-Coating to reduce platelet adhesion. ## Clinical Evidence No clinical data. Substantial equivalence demonstrated via in-vitro performance evaluations including gas transfer, hemolysis, pressure drop, mechanical integrity, priming volume, heat exchanger performance, defoaming, filtration efficiency, flow rate, and tubing connection strength. ## Technological Characteristics Materials: polycarbonate, stainless steel, polyester, polypropylene, polyethylene, and X-Coating. Principle: hollow fiber membrane diffusion for gas exchange; external water bath for heat exchange. Form factor: integrated oxygenator/heat exchanger with detachable hardshell reservoir. Sterilization: ethylene oxide. Biocompatibility: ISO 10993 compliant. ## Regulatory Identification A cardiopulmonary bypass oxygenator is a device used to exchange gases between blood and a gaseous environment to satisfy the gas exchange needs of a patient during open-heart surgery. ## Special Controls *Classification.* Class II (special controls).

The CAPIOX® RX25 is for use with patients when the required blood flow rate will not exceed 7.0 I /min. ### Principles of Operation and Technology: The design of the CAPIOX® RX25 Hollow Fiber Oxygenator with/without Hardshell Reservoir is such that blood is collected into the reservoir via gravity or external vacuum. Blood may enter is such that brood is confect and/or the cardiotomy inlet port. The reservoir contains filtering devices to remove particulate matter and air. Blood is then pumped from the reservoir into the devices to remove partisance by blood temperature is controlled. After the blood exits the heat exchanger, it enters the oxygenator device whereby gas transfer (introduction of oxygen and removal of carbon dioxide) occurs. After gas transfer has occurred, the blood exits the device and is pumped towards the patient. #### Design and Materials: Design of the CAPIOX® RX25 Hollow Fiber Oxygenator with/without Hardshell Reservoir The dosign of the Orice whereby the oxygenator and heat exchanger are joined together, while the hardshell reservoir can be detached from the device assembly.

The oxygenator devices are used to provide for gas exchange between blood and a gaseous environment to satisfy the gas exchange needs of a patient during cardiopulmonary bypass surgery. Each of the integral heat exchangers is used to warm or cool blood and/or perfusion fluid as it flows through the device. The respective hardshell reservoirs are each used to collect and store blood during the bypass procedure. Filters are present in each device to facilitate air and particulate removal. The new device and the predicate devices may each be used in Vacuum Assisted Venous Drainage and Post-Operative Chest Drainage procedures. - Principles of Operation and Technology: The technology of the subject device and the . predicate devices are essentially identical. The devices operate in a manner where blood is collected into the reservoir. The blood may enter the reservoir via the venous inlet or the cardiotomy inlet. The reservoirs each contain filtering/defoaming devices that facilitate the removal of particulate matter and air. Blood is then pumped from the reservoir into the heat exchanger device whereby blood temperature is controlled with the use of an external water bath. After the blood exits the heat exchanger, it enters the oxygenator device whereby gas transfer occurs (i.e., introduction of oxygen; removal of carbon dioxide). The transfer process occurs via diffusion across the walls of the hollow fiber membranes contained within the oxygenator. After gas transfer has occurred, the blood exits the devices and is pumped towards the patient. {3}------------------------------------------------ - Design and Materials: The design and the materials of the CAPIOX® RX25 Hollow Fiber .
