Adhesive sealant composition

This invention is related to an adhesive composition which may be used to bond or seal tissue in vivo. The adhesive composition is readily formed from a two component mixture which includes a first part of a protein, preferably a serum albumin protein, in an aqueous buffer having a pH in the range of about 8.0-11.0 and a second part of a water-compatible or water-soluble bifunctional crosslinking agent. When the two parts of the mixture are combined, the mixture is initially a liquid which cures in vivo on the surface of tissue in less than about one minute to give a strong, flexible, pliant substantive composition which bonds to the tissue and is absorbed in about four to sixty days. The adhesive composition may be used either to bond tissue, to seal tissue or to prevent tissue adhesions caused by surgery.

Contrast-enhanced diagnostic imaging method for monitoring interventional therapies

The present invention relates to a contrast-enhanced diagnostic imaging method for monitoring the efficacy of interventional therapies. The contrast agents useful in this method comprise an image-enhancing moiety (IEM) and a state-dependent tissue binding moiety (SDTBM). These contrast agents exhibit state-dependent binding to one or more components of a targeted tissue or tissue component and provide a detectable change in the signal characteristics of the agent once bound to the targeted tissue. As a result, these agents exhibit a binding affinity for, and thus image contrast of, the targeted tissue which changes as the tissue-state changes during therapy.

Tissue specific markers for preoperative and intraoperative localization and visualization of tissue

Surgeons may face the difficulty of preoperatively selecting the location for making an incision and intraoperatively identifying and differentiating targeted tissue for removal or for identification so that it is not removed along with neighboring or non-target tissue or so that neighboring or non-target tissue is not nicked, harmed, or removed accidentally. A tissue specific marker can include an aptamer or an affimer configured to bind to a pre-selected target tissue and one or more indicator elements coupled with the aptamer or the affimer. The one or more indicator elements produce a signal thereby allowing identification of the target tissue in a preoperative and operative manner.
