A number of adhesion promotion methods have been developed to enhance PTFE bond strength. The primary methods currently used in industry are sodium etching and plasma etching. Results of ion beam treatment and laser surface roughening have also been reported in the literature, but do not have a significant presence as commercial processes.
Epidural administration: injection into the epidural space of the spinal cord.Epidural, (Greek): situated on or outside the dura mater, from epi- "on top of" + dura mater + -al. Adhesion (Latin) adhēsiōn- for Latin adhaesiōn- (stem of adhaesiō) a clinging, equivalent to adhaes(us), past participle of adhaerēre to adhere + -iōn- -ion.
Protein patterning – chessboard pattern. Biomaterials are materials that are used in contact with biological systems. Biocompatibility and applicability of surface modification with current uses of metallic, polymeric and ceramic biomaterials allow alteration of properties to enhance performance in a biological environment while retaining bulk properties of the desired device.
Steps may be taken during surgery to help prevent adhesions such as handling tissues and organs gently, using starch-free and latex-free gloves, not allowing tissues to dry out, and shortening surgery time. [12] An unfortunate fact is, that adhesions are unavoidable in surgery and the main treatment for adhesions is more surgery.
Barrier release agents prevent adhesion by the development of a physical film or barrier between the forming surface and the concrete. Reactive release agents are chemically active and work by the process of a chemical reaction between the release agent and the free limes available in fresh concrete. A soapy film is created which prevents adhesion.
Mucoadhesion involves several types of bonding mechanisms, and it is the interaction between each process that allows for the adhesive process. The major categories are wetting theory, adsorption theory, diffusion theory, electrostatic theory, and fracture theory. [5]
The search for missing hiker Susan Lane-Fournier, 61, took a tragic turn after her body was found over the weekend in Welches, Oregon, an unincorporated community at the base of Mount Hood.
An adhesion barrier is a medical implant that can be used to reduce abnormal internal scarring following surgery by separating the internal tissues and organs while they heal. Surgeons have realized that proper surgical technique is crucial to reduce adhesion formation.
