Abstract: The present invention provides an aqueous composition and its use for dissolving blood clots in vivo or in clinical or research samples in vitro, said composition comprising at least one chaotropic agent, at least one chelating agent that complexes iron if the chaotropic agent does not complex iron and at least one surface-active emulsifier, the composition being buffered near pH 7.4. The process of dissolving the clot with the aqueous composition is advantageous because it is simple, inexpensive, rapid and can be applied in a variety of contexts, including basic research and clinical situations.

Abstract: A tissue marker formed of a biodegradable polymer having drug-delivery capabilities is combined with a sealant that encapsulates the tissue marker and which serves to help anchor the tissue marker against migration. The sealant is delivered to a site in dehydrated form and moisture inherent in tissue at the site expands the sealant. The expanded sealant is formed of a hydrogel and is therefore more compatible to the surrounding tissue than the material of the tissue marker. The sealant and the tissue marker are both bioabsorbed over time.

Abstract: Openings in a mammalian body made by any medical procedure or non-medical event are sealed with a bioabsorbable plug or sewn with a bioabsorbable suture. In one exemplary embodiment, the plug in dehydrated, unexpanded condition is pushed by a pushing device through the lumen of a needle until a first part of the plug is external to the opening and a second part is internal to the opening. The needle is then withdrawn while the position of the pushing device is maintained. The pushing device is then withdrawn, leaving the plug in sealing relation to the opening. The body's moisture causes the plug to expand to complete the sealing of the opening, or the expansion may be caused by exposure to air, light, or other stimulant. The opening may be formed in soft tissue, internal organs, or hard tissue. The plug seals the flow of liquid or gaseous biological fluids.
