DEVICE DESCRIPTION

SUBSTANTIAL EQUIVALENCE

Bencox Mirabo Cup Multi Hole is similar to the 510(k) cleared devices as mentioned below with respect to indications, design, specifications, operating principles and material.

Device	Manufacturer	Trade Name	510(k)
Predicate	Corentec Co.Ltd.	Bencox Mirabo Cup [System]	K172806
	Corentec Co.Ltd.	Bencox Mirabo Cup [System]	K162127 &K120924
AdditionalPredicates	Biomet Inc.	G7 Acetabular Cup [System]	K140669
			K121874
Reference	StrykerOrthopedics	Trident PSL	K983382; K143085

The subject devices Bencox Mirabo Cup Multi Hole and the predicate device Bencox Mirabo Cups are acetabular cups made of the same material and plasma-sprayed porous coatings with same pore size, porosity and coating thickness. The design, dimensional specification and locking mechanisms are identical to the previously cleared cups of the Bencox Mirabo Cup and hence subject devices Bencox Mirabo Cup Multi Hole will be compatible with same polyethylene acetabular liners, as well as all modular components and instrumentation cleared in the Bencox Mirabo Cup Acetabular System under K172806 and K162127 & K150007 & K120924.

The subject device Bencox Mirabo Cup Multi Hole is available in multi-hole design (8, 12 & 16 holes) in comparison to primary predicate, Bencox Mirabo Cup which is available in limited holes design (3 holes) cleared under K172806 and K162127 & K120924. The subject device Bencox Mirabo Cup Multi-hole design is similar to additional predicate, G7 Acetabular cup with limited & multi-hole designs with 3, 4, 11 & 16 holes.

Image /page/5/Picture/1 description: The image shows the "Corentec" logo. The logo consists of a stylized letter "C" with a red circle inside, followed by the text "orentec" in gray. Below the text is a thin red line, and below that is the text "IMPLANT SPECIALIST" in smaller gray letters.

PERFORMANCE DATA

Performance testing requirements was analyzed by engineering risk analysis which showed that the inclusion of variant, subject devices - Bencox Mirabo Cup Multi Hole, to the cleared predicate devices Bencox Mirabo Cup System under K172806, did not change the worst case configuration tested for all the performance testing as the dimensional specification of both subject and predicate devices are exactly same, except for acetabular cup deformation testing as per ISO 7206-12. Other performance testing conducted for predicate devices Bencox Mirabo Cup System cleared under K172806 is still valid for inclusion of the subject devices, Bencox Mirabo Cup Multi Hole.

The results of the engineering risk analysis & deformation testing as per ISO 7206-12 showed that the subject devices, Bencox Mirabo Cup Multi Hole are expected to be safe and effective for the proposed indications and are substantially equivalent to the predicate device, and could perform similar to Bencox Mirabo Cup System under K172806.

STERILIZATION & PACKAGING

Both subject devices and predicate devices are subjected to gamma sterilization. The sterilization and packaging validation for a shelf life of 5 years as per ISO & ASTM standards confirming the stability and effectiveness of packaging of the sterilized product during the shelf-life, by evaluating changes by accelerated aging, as per ASTM F1980 Sterilization validation as per ISO 11137-1 & 2 Sterilization of health care products -Radiation ensures sterility of the components for a SAL of 10 valid for predicate devices. Bencox Mirabo Cup System, is also applicable to subject devices, Bencox Mirabo Cup Multi Hole, as there is no change in the worst case tested in predicate devices submission.

CONCLUSION

Overall Bencox Mirabo Cup Multi Hole included in this PMN is similar to the identified primary predicate device and additional predicates. The identified minor differences between the subject devices and predicates do not constitute a new intended use and the minor differences in the technological characteristics do not affect or raise new queries of safety and effectiveness based on successful analysis conforming to recognized performance standards for hip replacement devices and has been adequately addressed in this premarket notification.

Regulation Number and Section

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
Classification. Class II.
