The PCO-OS and PCO-OB meshes are used for the reinforcement of tissues during surgical repair. They are indicated for the treatment of incisional hernias, abdominal wall repair, and parietal (i.e. pertaining to the walls) reinforcement of tissues. The non-resorbable polyester mesh provides long-term reinforcement of soft tissues. On the opposite side, the resorbable hydrophilic film minimizes tissue attachment to the mesh in case of direct contact with the viscera.
The PARIETEX COMPOSITE PCO-OS and PCO-OB Meshes are surgical meshes used during open (laparotomy) procedures or during laparoscopic procedures. The meshes are made from polyethylene terephtalate (polyester) and a collagen-based hydrogel component. The hydrophilic collagen film does not affect the physical performance characteristics of the meshes but serves to separate the coated side of the meshes from underlying tissues to minimize tissue attachment and ingrowth. The PCO-OB and PCO-OS Meshes are offered in several sizes and shapes to accommodate the type and approach of the surgical procedure. The Sofradim PCO-OS and PCO-OB Meshes are identical to the predicate PARIETEX COMPOSITE (PCO) meshes (K002699 and K040998) with the exception of the addition of a bi-dimensional textile flap to the current threedimensional reinforcement on the PCO Mesh. This flap is manufactured and sewn to the three-dimensional textile with the same polyester yarn as described in the predicate PCO meshes as well as other PARIETEX meshes (K982532 and K003990). The bidimensional flap has been added to the parent PCO Meshes to ease placement and fixation of the mesh during open surgery.
The provided text is a 510(k) summary for a medical device (surgical mesh). It describes the device, its intended use, and its substantial equivalence to predicate devices. However, it does not contain any information about acceptance criteria, device performance metrics, or a study specifically designed to prove that the device meets such criteria.
The "PERFORMANCE TESTING" section only states: "A study was conducted and demonstrated that the sewing of the additional flap does not adversely affect the safety or effectiveness of the device." This is a very general statement and lacks the specific details required for the requested table and study information.
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and the reported device performance: No specific acceptance criteria or performance metrics are mentioned.
- Sample size used for the test set and the data provenance: Not mentioned.
- Number of experts used to establish the ground truth and their qualifications: Not mentioned (as no specific performance study with ground truth is detailed).
- Adjudication method: Not mentioned.
- MRMC comparative effectiveness study: Not mentioned.
- Standalone performance study: Not mentioned.
- Type of ground truth used: Not mentioned.
- Sample size for the training set: Not mentioned.
- How the ground truth for the training set was established: Not mentioned.
The document focuses on demonstrating substantial equivalence to existing predicate devices, primarily by highlighting that the new device (PCO-OS and PCO-OB Meshes) is identical to the predicate PCO meshes (K002699 and K040998) with only the addition of a bi-dimensional textile flap. The "performance testing" mentioned is merely to confirm that this modification does not adversely affect safety or effectiveness, not to establish specific performance metrics against pre-defined acceptance criteria for the entire device.

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.(b)
