## Indications for Use

QuickMix is indicated for use in mixing BoneSource® Hydroxyapatite Cement and sodium phosphate solution. BoneSource is indicated for use in the repair of neurosurgical burr holes, contiguous craniotomy cuts and other cranial defects with a surface area no larger than 25 cm² per defect, and for augmentation or restoration of bony contour in the craniofacial skeleton including the fronto-orbital maler and mental areas.

## Device Story

QuickMix is a closed-system mixing device for BoneSource® Hydroxyapatite Cement (HAC). It consists of two syringes: one containing 0.25 M sodium phosphate solution and one containing HAC powder. The syringes connect tip-to-tip; the solution is injected into the powder syringe. The mixture is blended by manual agitation. A built-in filter in the mixing syringe allows excess liquid to be removed by retracting the plunger. Once mixed, the syringes are disconnected, the filter cap is removed, and the cement is ejected for clinical application. Used in neurosurgical or craniofacial procedures by surgeons to prepare bone cement for defect repair or contour restoration. The closed system minimizes exposure to the cement during preparation.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

System consists of two syringes and a filter assembly. Materials include medical-grade plastic syringes and a filter for liquid-solid separation. Operates via manual mechanical mixing and plunger-driven filtration. No energy source required. Non-sterile or sterile (implied by clinical use).

## Regulatory Identification

Methyl methacrylate for cranioplasty (skull repair) is a self-curing acrylic that a surgeon uses to repair a skull defect in a patient. At the time of surgery, the surgeon initiates polymerization of the material and forms it into a plate or other appropriate shape to repair the defect.

## Predicate Devices

#### Predicate Device

The DRG QuickMix mixing system is substantially equivalent to the BoneSource® Hydroxyapatite Cement (HAC) Expanded Kit distributed by Stryker Leibinger (K991398), which contains BoneSource® Hydroxyapatite Cement powder, one (or two based on the size of the kit) prefilled syringe containing sodium phosphate solution and a mixing spatula. Kits are provided in sizes ranging form 2.5g to 50g.

#### Device Description

The DRG QuickMix mixing system consists of a syringe containing a 0.25 M sodium phosphate solution and a mixing syringes containing BoneSource® Hydroxyapatite Cement. The mixing syringe also contains a filter which allows liquid, but not the cement mixture, to pass through it.

The sodium phosphate and cement mixing syringes are first connected tip to tip. The sodium phosphate solution is then injected into the mixing syringes and the cement mixture is shaken to thoroughly blend it. Excess liquid is then pulled from the mixing chamber through the filter assembly by retracting the solution plunger. The two syringes are then disconnected. The filter cap is then removed from the mixing syringe and the mixture is eiected.
