Features and Benefits

THE NEXT PHASE IN HERNIA REPAIR

Repairs1
The open monofilament mesh scaffold provides early integration and repair strength*

Remodels1
Preclinical testing confirms vascular integration and incorporation, with abundant mature collagen at 52 weeks. Gradually transfers load to native tissue over time*

Restores1
As Phasix™ Mesh is remodeled, it is replaced with functional tissue, ultimately resulting in a strong repair at one year*

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)4

MATERIAL STRUCTURE1

Material structure can impact host response.5

Consider these features of monofilament versus multifilament structures:

  • Monofilament mesh design allows for a prompt fibroblastic response through the open interstices of the mesh1
  • 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 response6
  • It has been reported that the surface area of multifilament material is 157% higher than monofilament materials6

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.

    Disclaimers

    • Not all products, services, claims or features of products may be available or valid in your local area. Please check with your local BD representative.

    • Please consult product labels and instructions for use for indications, contradictions, hazards, warnings, and precautions.

    Indications

    Phasix™ Mesh is indicated to reinforce soft tissue where weakness exists, in patients undergoing abdominal, plastic, and reconstructive surgery in ventral hernia repair and other abdominal fascial defect procedures.

     Contraindications

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

    Warnings

    1. Phasix™ Mesh must not be put in direct contact with the bowel or viscera.

    2. The use of any mesh or patch in a contaminated or infected wound can lead to fistula formation and/or extrusion of the mesh.

    3. Mesh manufacture involves exposure to tetracycline hydrochloride and kanamycin sulfate. The safety and product use for patients with hypersensitivities to these antibiotics is unknown. The use of this mesh in susceptible patients with known allergies to tetracycline hydrochloride or kanamycin sulfate should be avoided.

    4. The safety and effectiveness of Phasix™ Mesh in the following applications has not been evaluated or established: a. Pregnant or breastfeeding women b. Pediatric use c. Neural and cardiovascular tissue.

    5. If an infection develops, treat the infection aggressively. Consideration should be given regarding the need to remove the mesh. An unresolved infection may require the removal of the mesh.

    6. To prevent recurrences when repairing hernias, the mesh should be sized with appropriate overlap for the size and location of the defect, taking into consideration any additional clinical factors applicable to the patient. Careful attention to mesh fixation placement and spacing will help prevent excessive tension or gap formation between the mesh and fascial tissue.

    7. The mesh is supplied sterile. Prior to use, carefully examine package and product to verify neither is damaged and that all seals are intact. Do not use if the foil pouch or package is damaged or open, or if the center of the temperature indicator on the foil pouch is black.

    8. This mesh has been designed for single use only. Reuse, reprocessing, resterilization, or repackaging may compromise the structural integrity and/or essential material and design characteristics that are critical to the overall performance of the mesh and may lead to mesh failure which may result in injury to the patient. Reuse, reprocessing, resterilization, or repackaging may also create a risk of contamination of the mesh and/or cause patient infection or cross infection, including, but not limited to, the transmission of infectious diseases from one patient to another. Contamination of the mesh may lead to injury, illness, or death of the patient or end user.

    9. If unused Phasix™ Mesh has been in contact with instruments or supplies used on a patient or contaminated with body fluids, handle and dispose of in accordance with accepted medical practice and applicable local, state, and federal laws and regulations to prevent risk of transmission of viral infections.

    10. This mesh is not for the use of repair of pelvic organ prolapse via transvaginal approach.

    11. This mesh is not for the use of treatment of stress urinary incontinence.

    12. Phasix™ Mesh has not been studied for use in breast reconstructive surgeries. 

     Precautions

    1. Please read all instructions prior to use.

    2. Only physicians qualified in the appropriate surgical techniques should use this mesh. Users should be familiar with mesh strength and size requirements. Improper selection, placement, positioning, and fixation of the mesh can cause subsequent undesirable results.

    3. Clinical data in accordance with EU MDR has not been established for laparoscopic/robotic procedures.

    4. The safety and effectiveness of Phasix™ Mesh in the proximity of existing or excised cancer has not been established. 

     Adverse Reactions.

    In preclinical testing, Phasix™ Mesh elicited a minimal tissue reaction characteristic of foreign body response to a substance. The tissue reaction resolved as the mesh was resorbed. Possible complications may include, but are not limited to 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 product package insert for more detailed safety information and instructions for use.
