1. A gelling sealant for a medical device, said gelling sealant comprising:
- a viscoelastic material exhibiting a first viscosity during introduction into a body cavity; and
a second viscosity after dwelling within the body cavity for a predetermined amount of time, said body cavity being adjacent a medical device adapted to occlude at least a portion of said body cavity;
said viscoelastic material providing enhanced impermeability to the portion of said body cavity occluded by the medical device.

Abstract
Gelling sealants that promote enhanced impermeability to medical devices is provided. The gelling sealants include various viscoelastic materials that exhibit a first viscosity upon introduction into a body cavity and a second viscosity after dwelling within the body cavity for a predetermined amount of time. The gelling sealants thicken and provide a bacterial barrier after introduction into a body cavity by adhering to the inside surfaces of the body cavity.

21. A system for reducing or eliminating leakage around medical devices that include an inflation cuff, said system comprising:
-
a medical device that includes an inflation cuff and is adapted for introduction into a body cavity to occlude at least a portion of said body cavity; a viscoelastic material exhibiting; a first viscosity during introduction into a body cavity; and a second viscosity after dwelling within the body cavity for a predetermined amount of time, said body cavity being adjacent said medical device adapted to occlude at least a portion of said body cavity; and means for introducing said viscoelastic material into said body cavity adjacent said medical device so that the material transitions to the second, higher viscosity thereby reducing or eliminating leakage around the inflation cuff. - View Dependent Claims (22, 23)
