Abstract
A medical sealant composition and method for coupling the medical article to skin using the medical sealant composition. The medical sealant composition can include an unsaturated rubber hydrocarbon having at least one hydrosilyation-crosslinkable functional group and a crosslinking agent having at least one SiH group per molecule. The medical sealant composition can cure at 35 degrees C. in less than 20 minutes. The method can include applying the composition to one or both of a medical article and skin when the composition is in an uncured state; applying the medical article to the skin; and allowing the composition to cure to form a sealant between the medical article and the skin.
Claims22
A medical sealant composition comprising:
- an unsaturated rubber hydrocarbon having at least one hydrosilylation-crosslinkable functional group and a crosslinking agent having at least one Sill group per molecule, wherein the composition is curable at 35 degrees C. in less than 20 minutes,
- wherein the composition has a first (uncured) state having a viscosity in the range of 15,000 cP to 1,000,000 cP.
A method for coupling a medical article to skin, the method comprising:
- providing a medical article;
- providing a composition comprising an unsaturated rubber hydrocarbon having at least one hydrosilylation-crosslinkable functional group and a crosslinking agent having on the average at least one Sill group per molecule;
- applying the composition to one or both of the medical article and skin when the composition is in an uncured state;
- applying the medical article to the skin;
- and
- allowing the composition to cure to form a sealant between the medical article and the skin.
