Device Facts

• Record ID: K080511
• Device Name: PLEXUR-P
• Applicant: Osteotech, Inc.
• Product Code: MQV · Orthopedic
• Decision Date: Apr 21, 2008
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3045
• Device Class: Class 2

Intended Use

PLEXUR P is intended for use in filling bony voids or gaps of the skeletal system (i.e., spine, pelvis and extremities) that are not intrinsic to the stability of the bony structure. These defects may be surgically created osseous defects or osseous defects resulting from traumatic injury to the bone. Plexur P may also be used as a bone graft extender in the spine. PLEXUR P is resorbed/remodeled and is replaced by host bone during the healing process.

Device Story

PLEXUR P is a bone void filler composed of processed human allograft bone tissue and a resorbable polymer. Provided in various ready-to-use physical forms, geometries, and sizes; surgeon may cut or shape the material to fit the specific defect. Intended for single-patient use in the spine, pelvis, and extremities. During the healing process, the device is resorbed and remodeled, being replaced by host bone. The device supports bone in-growth and new bone formation. Processing steps include viral inactivation for HIV, hepatitis B and C, and CMV.

Clinical Evidence

No clinical data. Evidence consists of animal studies demonstrating that PLEXUR P supports bone in-growth and new bone formation at a rate at least comparable to predicate devices.

Technological Characteristics

Composition: Processed human allograft bone tissue and resorbable polymer. Form: Ready-to-use, shapeable/cuttable solid. Mechanism: Resorption and remodeling into host bone. Sterilization/Processing: Includes viral inactivation steps for HIV, hepatitis B/C, and CMV.

Indications for Use

Indicated for filling bony voids or gaps in the skeletal system (spine, pelvis, extremities) not intrinsic to structural stability. Applicable to surgically created osseous defects or defects from traumatic injury. May be used as a bone graft extender in the spine.

Regulatory Classification

Identification

A resorbable calcium salt bone void filler device is a resorbable implant intended to fill bony voids or gaps of the extremities, spine, and pelvis that are caused by trauma or surgery and are not intrinsic to the stability of the bony structure.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Resorbable Calcium Salt Bone Void Filler Device; Guidance for Industry and FDA.” See § 888.1(e) of this chapter for the availability of this guidance.

| Trade/Proprietary/Model Name: | PLEXUR P |
|-------------------------------|-----------------------------|
| Common or Usual Name: | Bone Void Filler |
| Classification Name: | Resorbable Bone Void Filler |

- 3. Devices to Which New Product is Substantially Equivalent:
PLEXUR P is substantially equivalent, for the purpose of this 510(k), to other devices that have received 510(k) clearance for similar indications for use.

- 4. Device Description:
PLEXUR P is bone void filler that contains as its principal constituents processed human allograft bone tissue and a resorbable polymer. PLEXUR P is produced in various physical forms/shapes/geometries and may be further shaped or cut by the surgeon to meet the particular needs and preferences of the surgeon. PLEXUR P is intended for use as bone void filler in bony voids or gaps of the skeletal system (i.e., spine, pelvis, and extremities) not intrinsic to the stability of the bony structure. Plexur P mav also be used as a bone graft extender in the spine. PLEXUR P is provided in ready-to-use form in various package sizes by volume or dimension and is intended for single patient use.

- 5. Intended Use/Indications
PLEXUR P is intended for use in filling bony voids or gaps of the skeletal system (i.e., spine, extremities, and pelvis) that are not intrinsic to the stability of the bony structure. These defects may be surgically created osseous defects or osseous defects resulting from traumatic injury to the bone. Plexur P may also be used as a bone graft extender in the spine. PLEXUR P is resorbed/remodeled and is replaced by host bone during the healing process.

{1}------------------------------------------------

## 6. Technical Comparison

PLEXUR P is substantially equivalent to one or more of the predicate devices with respect to materials. PLEXUR P contains human allograft bone tissue and polymer that are resorbed and/or remodeled into new host bone. The predicate devices also contain materials that are resorbed and /or remodeled into new host bone. Moreover, like the predicate devices, PLEXUR P is provided ready-to-use in various forms that can be cut or shaped by the user into various shapes or sizes.

- 7. Performance Data
The results of studies in animal showed that PLEXUR P supports bone in-growth and new bone formation to an extent at a rate at least comparable to predicate devices.

- 8. Viral Inactivation
In the production of Plexur P, the allograft bone is subjected to processing steps that have been shown to inactivate viruses, including HIV, hepatitis B and C and CMV.
