Meshgraft™ II Tissue Expansion
System Instruction Manual
INDICATIONS FOR USE
The
Meshgraft
II Tissue Expansion System (See Fig. 1–3) is intended to create perforations in a skin graft so it can
be expanded to cover a recipient site that is larger than the donor site. Use of the
Meshgraft
II System also provides
improved drainage, increased edge exposure, minimal contracture and conformance to irregular body surfaces.
DESCRIPTION
The
Meshgraft
II Tissue Expansion System is a manually operated instrument used with a
Dermacarrier™
II Skin Graft
Carrier to obtain greater area coverage from a conventional sheet graft. It consists of a continuous feed roller, a cutter, a
guidance plateau, a ratchet handle, and a curved stabilizing bar/carrying handle. The guidance plateau ensures proper
alignment of the
Dermacarrier
II Skin Graft Carrier and the cutter. The ratchet handle facilitates proper advancement.
The variable expansion ratios* available (See ACCESSORIES) permit the user to adapt the expansion ratio to the
specific surgical procedure. The degree of expansion selected is determined primarily by the contour of the recipient
site. It is desirable to use minimal expansion on a sharply contoured area which will have a high degree of flexion
after healing.
*To illustrate the meaning of expansion ratio, when 1 sq. in. (6 sq. cm) of donor skin is meshed in the
Meshgraft
II
Tissue Expansion System using a specific expansion such as 6 to 1, that 1 sq. in. (6 sq. cm), when fully expanded will
cover approximately 6 sq. in. (40 sq. cm) in the recipient area.
DESCRIPTION OF RATCHET HANDLE (See Fig. 12)
The 00-2195-022-00 Ratchet Handle has been fabricated for use with the 00-2195-001-00
Meshgraft
II Tissue
Expansion System. The ratchet handle is easily disassembled for cleaning and is completely autoclavable.

DESCRIPTION OF SKIN GRAFT CARRIER (See Fig. 4)
The
Dermacarrier
II Skin Graft Carrier is a disposable cellulose propionate board 3 in. (7.6 cm) wide. It is available in
ratios of 1.5:1, 3:1, 6:1, and 9:1. Each carrier is sterile packaged in a film/Tyvek pouch, 20 carriers per box. The carriers
are sterilized and ready to use once the packaging, which maintains their sterility, is removed.
CONTRAINDICATIONS
Meshed grafts may not be suitable for patients known to form keloids, or in areas subject to constant trauma
(e.g., popliteal fossa). Use in these areas has resulted in severe scar contractures.
WARNINGS AND PRECAUTIONS
To avoid serious injury to the patient and operating staff while using the
Meshgraft
II Tissue Expansion System, the user
must be thoroughly familiar with its function, application, and instructions for use.
The user and operating staff must always pay close attention to the CLEANING PRECAUTIONS and MANUAL AND
AUTOMATED CLEANING AND DISINFECTION PROCESS INSTRUCTIONS. Failure to follow these instructions may
damage the
Meshgraft
II Tissue Expansion System.
Use only
Dermacarrier
II Carriers with a 2195 catalog number with the
Meshgraft
II Tissue Expansion System
(See ACCESSORIES). Use of any other carrier will damage the skin graft and/or the device.
The carriers are intended for single use only. Reuse may result in an unsatisfactory mesh pattern.
The
Dermacarrier
II Carrier should be used grooved side up and the skin must be placed on this side of the carrier. If
the skin is placed on the smooth side of the
Dermacarrier
II Skin Graft Carrier (upside down), the graft will be shredded
into long strips and will be unusable.
