Intended Use

AFB is indicated for use in surgical procedures in which soft tissue transection or resection with staple line reinforcement is needed.

Device Story

AFB (Absorbable Foam Buttress) is a sterile, single-use device consisting of a cartridge and anvil carrier with attached buttressing material. It integrates into endoscopic and open linear cutting/transecting staplers. During surgery, the device reinforces the staple line while tissue is simultaneously cut and stapled. It is used by surgeons in clinical settings (e.g., VATS, open cases). The material is a synthetic, bioabsorbable copolymer that degrades within 120 days. By providing reinforcement to the staple line, the device aims to improve surgical outcomes in tissue resection/transection procedures.

Clinical Evidence

No clinical data. Evidence consists of non-clinical bench testing (polymer composition, viscosity, foam thickness, pore size, tensile strength, moisture, residuals, force to fire, tear resistance) and preclinical animal studies evaluating pharmacokinetics, toxicology, biocompatibility, and absorbability.

Technological Characteristics

Synthetic bioabsorbable copolymer foam buttress; 0.03" (0.75 mm) thickness. Integrated into endoscopic and open linear staplers. Sterilized for single-patient use. Biocompatibility and absorption profile similar to synthetic absorbable sutures.

Indications for Use

Indicated for patients undergoing surgical procedures requiring soft tissue transection or resection where staple line reinforcement is necessary.

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.

Device Description: The AFB (Absorbable Foam Buttress) Reload is a sterile, single patient use device which consists of two components: a cartridge and an anvil carrier. A strip of buttressing material is attached to both the cartridge and anvil carrier. AFB reinforces the staple line in soft tissue while it is simultaneously being cut and stapled. AFB is prepared from a synthetic, {1}------------------------------------------------ bioabsorbable copolymer similar to that used in synthetic absorbable sutures. The AFB is integrated into endoscopic and open linear cutting/transecting staplers and reload cartridges. The two product reload cartridge configurations are suitable for the Endopath™ Endoscopic Linear Cutter used for VATS cases and the Linear Cutter used for OPEN cases. The dimensions of AFB with a 0.03" (0.75 mm) thickness, accommodates the above-cited Ethicon-Endosurgery devices: | Device | Dimensions of AFB<br>(Attached to Staple<br>Cartridge) (inches) | Dimensions of AFB<br>(Attached to Staple Anvil<br>Carrier) (inches) | |----------------------------------------------|-----------------------------------------------------------------|---------------------------------------------------------------------| | Endoscopic Linear Cutter<br>45mm Application | 1.83 × 0.34 | 1.83 × 0.59 | | Linear Cutter 75 mm<br>Application | 3.19 x 0.44 | 3.30 x 0.63 | - E. Indications for Use: AFB is indicated for use in surgical procedures in which soft tissue transection or resection with staple line reinforcement is needed. - F. Technological Comparison: Substantial equivalence for AFB is based upon two separate categories of predicate devices. The first category contains predicate devices that address the intended use, mechanism of use, and application (i.e., two marketed buttress materials, namely Peri-Strips Dry® manufactured by Bio-Vascular, Inc. and Seamguard™ manufactured by W. L. Gore). The second category of predicate devices addresses the composition of AFB in regard to its biocompatibility, safety data, absorption, and biodegradability (i.e., Coated Vicryl II and Monocryl sutures). {2}------------------------------------------------ #### II. TESTING #### A. Non-Clinical Testing Non-clinical testing was conducted on AFB to characterize the product. This testing included polymer composition by NMR, inherent viscosity, foam thickness, pore size, tensile strength, moisture content, residuals, force to fire and tear resistance. - Preclinical Testing B. Preclinical testing on the copolymer was conducted in multiple species to establish pharmacokinetics, toxicology, biocompatibility, and absorbability. AFB, although bioabsorbed in < 120 days, was subjected to a preclinical testing regimen consistent with that for a long-term implant. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the seal of the U.S. Department of Health & Human Services.
