Patent

Disclosed are methods for draping a surgical site prior to surgery. Specifically, the methods of this invention involve the in situ formation of a cyanoacrylate polymeric drape on the skin surface of a patient peripheral to the surgical site. Surgery is then conducted at the surgical site.

This invention relates to sterilized cyanoacrylate adhesive compositions with x-ray imagining capabilities, methods of making such compositions, and methods of using such compositions.

A new step in the condensation of formaldehyde and esters of 2-cyanoacetic acid to produce 2-cyanoacrylate esters which consists essentially of catalyzing the reaction by means of a mixture of an acid and the salt of a primary or secondary amine with the same stronger acid. To be effective, the catalytic mixture should have a pH value of 5 or less when exact amounts of its components are dissolved in 25 ml. of water. If the catalytic mixture is to include an acid which is not readily soluble in water (e.g. organic acids), then the pH is measured in 25 ml.

A new adhesive method using an adhesive composition including cyanoacrylate adhesive and a stabilizing agent to join together portions of a substrate, particularly useful in suturing and similar medical procedures, is disclosed.

The present invention provides a surgical fastener (1) made of a bioabsorbable elastomeric material for the repair of tissues. The fastener may be elongated, thereby creating a compression force across or within the tissue being repaired. The present invention also includes embodiements drawn to methods of using the surgical fastener, such as applying the surgical fastener to a ruptured meniscus or using the surgical fastener to attach a fibrous implant or tissue transplant on or in a living tissue, and an apparatus for installing the fastener. 

A polymerizable monomer adhesive composition includes a 1,1-disubstituted ethylene monomer and at least one slip additive, where the slip additive causes a polymer film formed from the monomer to have a lower coefficient of friction than in an absence of the slip additive. The slip additive can be selected from, inter alia, fluorinated monomers or polymers, fluorinated additives, siloxane-containing monomers or polymers, siloxane-containing additives, fluorinated siloxanes, and long chain fatty acid esters.

A medical and surgical adhesive compostion is described which provides an increased elasticity of the adhesive film and which is free of side effects, comprising 2-ehtyl cyanoacrylate, butyl acrylate and 3-methacryloxy sulfolane.

Latent fingerprints are developed by exposing them to vapours generated from a thin film of a storage stable cyanoacrylate monomer and a thixotropic additive in sufficient amount to render the composition substantially non-flowable. The monomer film should have a surface area at least 129 sq. cm.

An envelope package for the monomer composition has inner polyethylene surfaces. The envelope may be peeled open to expose the inner surfaces coated with a film of the composition.

Polymeric materials and methods that realize a gel-type intraocular lens that is formed in situ within the lens capsule of the eye. The polymeric material of the intraocular lens includes reactive end groups that effectively bond with lens capsule walls, thus eliminating space between the intraocular lens and the lens capsule walls and significantly reducing the proliferation of lens epithelial cells which can cause unwanted posterior capsule opacification.
