Phasix™ Mesh provides a fully resorbable monofilament scaffold for rapid tissue incorporation that has been designed to allow for the repair strength of a synthetic mesh along with the remodeling characteristics of a biologic graft.1

The Next Phase in Hernia Repair


Repairs. *
The open monofilament mesh scaffold provides early integration and repair strength.*

Remodels. *
Preclinical testing confirms vascular integration and incorporation, with abundant mature collagen at 52 weeks. Gradually transfers load to native tissue over time.*

As Phasix™ Mesh is remodeled, it is replaced with functional tissue, ultimately resulting in a strong repair at one year.*

* Preclinical data on file. Results may not correlate to clinical performance in humans.

What is Phasix™ Mesh?

Phasix™ Mesh is a knitted monofilament mesh scaffold using Poly-4-hydroxybutyrate (P4HB), a biologically derived, fully resorbable material.

  • Monomer form (4HB) is a naturally occurring human metabolite found in the brain, heart, liver, kidney, and muscle.
  • Predictably resorbs through hydrolysis, as P4HB metabolizes into biocompatible byproducts (CO2 and H2O).


Material Structure1

Material structure can impact host response.2 Consider these features of monofilament versus multifilament structures.

  • Monofilament mesh design allows for a prompt fibroblastic response through the open interstices of the mesh.
  • Material designs with complex architecture can have greater surface area and niches that bacteria can use as a haven from tissue ingrowth, neovascularization, antibiotic treatment, and host inflammatory response.3
  • It has been reported that the surface area of multifilament material is 157% higher than monofilament materials.3

Tissue Incorporation1

Study objective: Evaluate material strength and histopathology of Phasix™ Mesh.

Study design: A 3-centimeter round defect was created in the ventral abdominal wall of 25 Yucatan mini-pigs (average weight 38 kg). Phasix™ Mesh was fixated directly over the defect with SorbaFix™ resorbable tacks. Ball burst testing and histopathology were conducted at 6, 12, 26, and 52 weeks.

Results: Early tissue ingrowth, vascular integration, and incorporation of Phasix™ Mesh into the ventral abdominal wall, plus abundant mature collagen formed around the remaining fibers at 52 weeks.

Phasix Mesh is indicated to reinforce soft tissue where weakness exists in patients undergoing abdominal plastic and reconstructive surgery, or for use in procedures involving soft tissue repair of ventral or inguinal hernias, or other abdominal fascial defects that require the addition of a reinforcing or bridging material to obtain the desired surgical result.

Because Phasix Mesh is fully resorbable, it should not be used in repairs where permanent wound or organ support from the mesh is required.

Phasix™ Mesh must not be put in direct contact with bowel or viscera. The safety and product use for patients with hypersensitivities to tetracycline hydrochloride or kanamycin sulfate is unknown. Use of this device in patients with known allergies to these antibiotics should be avoided. The safety and effectiveness of Phasix Mesh in pediatric use has not been evaluated or established. If an infection develops, treat the infection aggressively. An unresolved infection may require removal of the device.

Adverse Reactions
Possible complications include infection, seroma, pain, mesh migration, wound dehiscence, hemorrhage, adhesions, hematoma, inflammation, allergic reaction, extrusion, erosion, fistula formation and recurrence of the hernia or soft tissue defect.

Please consult package insert for more detailed safety information and instructions for use.
