Abstract
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. It is based on the discovery that remarkable improvements are obtained by adding a step of removing stabilizing agent from such adhesive compositions in the manufacturing process with the prior known steps of (a) providing an adhesive composition including cyanoacrylate adhesive and a stabilizing agent, (b) presenting a substrate to receive at least a portion of such cyanoacrylate adhesive and (c) applying such portion to the substrate. Devices for use in performing the method are described.
Claims18
A method for the fabrication of a cyanoacrylate adhesive so as to minimize the presence of contaminants and extraneous additives in the resulting cured adhesives and enhancing the cure speed of stabilized cyanoacrylate adhesive by a treatment that removes excessive stabilizers prior to application onto a substrate, the method comprising the steps of (a) providing a stable adhesive composition comprising cyanoacrylate adhesive and a stabilizing agent to produce a cyanoacrylate adhesive composition, (b) presenting a substrate to receive at least a portion of the cyanoacrylate adhesive composition and (c) applying the cyanoacrylate adhesive composition to the substrate,
- the improvement comprising the step of removing stabilizing agent from the cyanoacrylate adhesive composition prior to the step of applying.
A method for the fabrication of a cyanoacrylate adhesive so as to minimize the presence of contaminants and extraneous additives in the resulting cured adhesives and enhancing the cure speed of stabilized cyanoacrylate adhesive by a treatment that removes excessive stabilizers prior to application onto a substrate, the method comprising the following steps:
- providing stable adhesive composition comprising cyanoacrylate adhesive and a stabilizing agent to produce a cyanoacrylate adhesive composition;
- removing stabilizing agent from the cyanoacrylate adhesive composition;
- presenting a substrate to receive at least a portion of the cyanoacrylate adhesive composition;
- and
- applying the cyanoacrylate adhesive composition to the substrate.
