The integral heat exchanger is used to warm or cool the blood or perfusion fluid flowing through the device. The device is intended for use during extracorporeal circulation for up to 6 hours. ## Description CAPIOX® 308 Hollow Fiber Oxygenator (CAPIOX 308) contains an integrated heat exchanger. The CAPIOX 308 oxygenator is a membrane oxygenator consisting of microporous polypropylene hollow fibers. Blood flows internal to the hollow fibers while gases flow outside the fibers. The heat exchanger consists of stainless steel pipes with blood flowing inside the pipes and water flowing outside the pipes. A thermistor probe is located near the outlet port of the oxygenator which can be connected to accessory temperature monitoring equipment if desired. 131 --010-- {1} II - Summary and Certification Summary of Safety and Effectiveness ## Substantial Equivalence The CAPIOX® 308 Oxygenator with integrated heat exchanger is substantially equivalent to the Avecor 0800 2A Oxygenator and Omnitherm Heat Exchanger as follows: **Intended use**: same ## Design and Materials: The CAPIOX 308 has an integrated heat exchanger while the Avecor 0800 2A oxygenator is designed to operate with the separate Avecor Omnitherm Heat Exchanger. Gas exchange is accomplished through hollow polypropylene fibers in the CAPIOX 308. Blood flows through the fibers while gas flows on the outside the fibers. The Avecor 0800 2A has a flat reinforced silicone rubber membrane envelope wound in a spiral coil around a polycarbonate spool. The entire unit is encased by a tight-fitting silicone rubber sleever. The interior of the envelope is the gas compartment containing a spacer screen permitting gas flow. The heat exchanger of the CAPIOX 308 uses straight stainless steel tubes as blood conduits with water flowing on the outside of the tubes. The Avecor Omnitherm Heat Exchanger is a tube-in-shell design, and consists of thin-walled aluminum tubes containing aluminum rod inserts shaped in a "staircase" pattern to promote gentle mixing of the blood and to conduct heat from the tube walls into the bloodstream. The water and blood paths are separated at each end of the device by a pair of manifolds, between which is an air space which is open to the atmosphere through a hole in the shell of the heat exchanger. Water flows on the outside of the tubes. 011 {2} II - Summary and Certification Summary of Safety and Effectiveness Although some design dissimilarities exist, the performance testing results demonstrate that these differences do not present significant differences in the function and intended uses of the devices. ## Technology and Principles of Operation Both devices use membrane technology. The CAPIOX 308 uses hollow fibers while the Avecor 0800 2A uses a membrane plate. Some form of pumping mechanism is utilized to transfer blood from the reservoir to the heat exchanger (separate for Avecor, integral for CAPIOX 308) and from there to the oxygenator component. The technology and principles of operation for the CAPIOX 308 and the Avecor 0800 2A are substantially equivalent. ## Specifications Table 1 | Effective surface area of oxygenator | 0.8 m² | 0.8 m² | | --- | --- | --- | | Heat Exch. Max. water Pressure | 42 PSI | 45 PSI | | Blood Flow Rate | 0-0.8 LPM | 0-1.2 LPM | | Static Priming Volume (Oxygenator and heat exchanger) | 95 mL | 148 mL | | Dimension | Height: 24.0 cm Width: 10.5 cm Weight: 400 g | Oxygenator Height: 38.5 cm Width: 8.0 cm Weight: 530 g Heat Exchanger Height: 47.5 cm Width: 6.5 cm Weight: 230 g | These differences do not affect the substantial equivalence of the devices since both provide adequate gas exchange for clinical use. y {3} II - Summary and Certification Summary of Safety and Effectiveness ## Performance Comparison of the CAPIOX 308 with integrated heat exchanger and the Avecor 0800 2A and Omnitherm Heat Exchanger performance was conducted. The test results indicated the CAPIOX 308 performs in a substantially equivalent manner to the Avecor 0800 2A and Omnitherm Heat Exchanger. The CAPIOX 308 with integrated heat exchanger and the Avecor 0800 2A and Omnitherm Heat Exchanger are substantially equivalent in intended use, design and materials, technology/principles of operation, specifications and performance. Differences as described above do not raise new issues of safety or effectiveness.
