fig7 the compression of the tissue of the patient could be compression of the pharyngeal wall pw or compression of tissue surrounding the pharyngeal wall pw for example fatty pads after the compression the pads 24 are deflated and the expander member 20 is removed from the airway pa as illustrated in fig9 leaving compressed right and left lateral pharyngeal wall portions rlpw llpw and an enlarged cross sectional area of the pharyngeal airway pa in addition to compressing the walls of the pharyngeal airway pa the compressed walls may be stabilized in a compressed state to ensure longer lasting retention of the therapeutic benefits of the enlarged airway pa this stabilization can include injecting a bio adhesive or bio sealants into the tissue adjacent the treated portions of the pharyngeal wall an example of bio adhesives includes cyanoacrylates without intending to be a limiting example these include 2 octyl cyanoacrylate and 2 butyl cyanoacrylate the 2 octyl cyanoacrylate is developed by closure medical corp raleigh n c usa for use to treat topical skin wounds oral cancers and periodontal disease it may last 1 2 weeks with faster absorbing products in development the 2 butyl cyanoacrylate is used as a skin protectant and dental cement and is available from glustitch inc delta bc canada biocompatible adhesives also include surgical adhesives such as those developed by cryolife international inc kennesaw ga usa whose product is composed of purified bovine serum albumin 45 and cross linking agent glutaraldehyde 10 similar formulations include natural proteins e g collagen gelatin with aldehyde or other cross link agents such bio sealants may be fibrin sealants examples include blood derived products e.
