Dual Porosity Expanded Polytetrafluoroethylene for Soft-Tissue Augmentation

Abstract

This novel dual porosity expanded polytetrafluoroethylene is associated with reduced inflammation and more extensive tissue incorporation as compared with the currently available form. These results suggest a dual porosity expanded polytetrafluoroethylene may provide a superior material for soft-tissue augmentation.

Advances in Segmental Endoprosthetic Reconstruction for Extremity Tumors: A Review of Contemporary Designs and Techniques

“…16,[25][26][27][28]36,[38][39][40]67 In the proximal tibia, the gastrocnemius fl ap can be reinforced using various materials such as artifi cial acrylic meshes (eg, Lars, Trevira) or other biologically derived devices. 19,24,39,[42][43][44][45] In the proximal humerus, the use of an Aortograft mesh 24,37,[42][43][44] has been suggested and reported by Marulanda et al 44 to decrease the risk of dislocation and subluxation of the reconstructed shoulder. Similar techniques, with appropriate modifi cations, could be applied during proximal femur and proximal tibia reconstructions.…”

“…Similar techniques, with appropriate modifi cations, could be applied during proximal femur and proximal tibia reconstructions. 24,37,[42][43][44] Similarly, coverage of the prostheses with a premolded sleeve consisting of different materials, including HA [55][56][57][58] and trabecular metals, 33,60,61 is currently under investigation. We anticipate that these new techniques and materials will be useful in improving soft-tissue integration.…”

“…41 Aortograft (InterGard Knitted Vascular Graft, Datascope, Montvale, NJ) is an ePTFE material that has been chosen for its durability in vivo and known soft-tissue ingrowth. 38,42,43 The senior author (G.D.L.) has employed this device for reconstruction of the rotator cuff and abductor muscles with good results.…”

Biocompatibility Comparison of Novel Soft Tissue Implants vs Commonly Used Biomaterials in a Pig Model

“…These materials are an improvement from other described alloplastic and autologous materials because they are relatively inert, are nontoxic, and have a relatively low complication rate. More recently, the use of ePTFE has gained popularity and is considered the gold standard for isolated soft tissue augmentation and replacement 12 – 13 , 16 . Although useful, ePTFE remains as a permanent, nonvascularized implant for the lifetime of the patient.…”

Evolution in Techniques: Lip Augmentation

“…The touted advantage of Advanta TM and its advance over Softform TM are in its dual porosity implant design. 4,5 Essentially, the outer portion is e-PTFE with a porosity of 50 mm. The inner core is a high or open porosity of 100 mm.…”
