The present invention provides an improved dispenser suitable for quickly and easily setting up and dispensing multi-part tissue sealants or other multi-part compositions requiring separation of the components until just prior to application on the tissue surface. The invention may further include an applicator having a handle and a blade attached to a first end of the handle. The invention may also include a dispensing tip having a blade attached to the distal end of the dispensing tip.

Apparatus and methods for dispensing an adhesive tissue sealant

A polyurethane dispersion and method of making are provided. The dispersion is stable in an alcohol-water mixture. The dispersion is a reaction product of: (i) at least one oligomeric polyactive hydrogen compound, wherein said compound is an alkyl, aryl, or aralkyl structure optionally substituted in and/or on the chain by N, O, S and combinations thereof, and wherein the compound is insoluble in 50:50 weight percent of said alcohol-water mixture; (ii) at least one polyisocyanate, and (iii) at least one polyactive hydrogen compound soluble in the alcohol-water mixture selected from the group consisting of a compound containing an ionic group, a compound containing a moiety capable of forming an ionic group, a compound containing a polyester, polyether, or polycarbonate group having a ratio of 5 or less carbon atoms for each oxygen atom, and mixtures thereof; and (b) at least one polyfunctional chain extender.

Polyurethane film-forming dispersions in alcohol-water system

An incise drape suitable for use in surgical procedures. The drape comprises a substantially transparent flexible film that has at least a portion of one major surface coated or covered with a pressure sensitive adhesive, and a two liners removably covering the adhesive. Each liner has a handle spaced from the opposite side edges of the film, and a body portion attached to the handle. The body portion of each liner extends along the adhesive from handle in the direction away from the other liner. The drape is repeatedly folded over from the opposite side edges of the film toward the handles so that the drape may be unfolded and the adhesive exposed by pulling the handles apart.

Surgical incise drape

A linerless, easy to apply surgical incise drape including a flexible film which has one major surface coated with a pressure sensitive adhesive and of the opposite major surface coated with a low adhesion backsize. The drape is rolled around a cylindrical core. The drape of the invention eliminates the need to use a separate liner to protect the adhesive surface of the drape, reducing the cost of the drape and eliminating waste.
