Device Facts

• Record ID: K110815
• Device Name: PARIETEX OPTIMIZED COMPOSTIE MESH
• Applicant: Sofradim Production
• Product Code: FTL · General, Plastic Surgery
• Decision Date: Apr 19, 2011
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 878.3300
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The PARIETEX™ Optimized Composite Mesh (PCO) is used for the reinforcement of tissues during surgical repair. It is indicated for the treatment of incisional hernias, abdominal wall repair and parietal (i.e. pertaining to the walls) reinforcement of tissues. The non-absorbable threedimensional polyester mesh provides long term reinforcement of soft tissues. On the opposite side, the absorbable hydrophilic film minimizes tissue attachment to the mesh in case of direct contact with the viscera.

Device Story

Surgical mesh for tissue reinforcement; used in incisional hernia and abdominal wall repair. Device consists of 3D multifilament polyester knit for long-term reinforcement; one side covered with absorbable, hydrophilic porcine collagen and glycerol film to minimize visceral tissue attachment. Film extends 5mm beyond reinforcement edge. Available in rectangular and round shapes. Used by surgeons in clinical settings. Polyester provides structural support; collagen film acts as barrier. Benefits include mechanical reinforcement and reduced post-operative adhesions.

Clinical Evidence

Bench testing and pre-clinical study conducted per FDA guidance. Results demonstrate improved mechanical properties and equivalent in-vivo tissue attachment minimization compared to predicate devices.

Technological Characteristics

Materials: 3D multifilament polyester knit, porcine collagen, glycerol. Form factor: Rectangular or round mesh with 5mm film overhang. Principle: Non-absorbable polyester for structural reinforcement; absorbable hydrophilic film for anti-adhesion barrier. No software or electronic components.

Indications for Use

Indicated for treatment of incisional hernias, abdominal wall repair, and parietal tissue reinforcement in patients requiring soft tissue reinforcement.

Regulatory Classification

Identification

Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Examples of surgical mesh are metallic and polymeric mesh for hernia repair, and acetabular and cement restrictor mesh used during orthopedic surgery.

## Summary comparing the technological characteristics of the subject and predicate devices:

The subject PARIETEX™ Optimized Composite Mesh (PCO) is equivalent to the predicate devices PARIETEX™ Composite Mesh (K002699 and K040998) in terms of its technological characteristics. No major technological changes are proposed to the predicate devices in this submission. Design modifications included a new collagen film formulation and changes to the knitting. Performance testing was performed on both predicate and proposed mesh. The results of a pre-clinical study and bench testing, performed in accordance with FDA's Guidance for the Preparation of a Premarket Notification Application for Surgical Mesh, demonstrate improved mechanical properties, and equivalent in-vivo minimizing tissue attachment property.

Performance data: Bench testing and pre-clinical testing has been conducted to evaluate the performance characteristics. Testing has shown that the PARIETEX™ Optimized Composite Mesh is equivalent in performance characteristics to the predicates PARIETEX™ Composite Mesh.
