CONTROLLED HYDROGEL DELIVERY OF FOCAL ADHESION KINASE INHIBITOR FOR DECREASED SCAR FORMATION

The formation of scars at a wound site is reduced by contacting the wound site with an effective dose of an inhibitor of focal adhesion kinase (FAK) formulated in a pullulan hydrogel The release profile of the FAK inhibitor can be adjusted according to the nature of the wound, e.g., excisional wounds, burn wounds, etc.

DRUG-COATED BALLOON CATHETERS FOR BODY LUMENS
20210361918 · 2021-11-25 ·

A balloon catheter for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen; the ballon catheter comprising: An elongated balloon; a coating layer overlying an exterior surface of the balloon wherein the coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent; and a length-control mechanism (600) which stretches and elongates the balloon during deflation, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

DRUG ELUTING BALLOON AND BALLOON CATHETER
20220016398 · 2022-01-20 ·

Disclosed is a drug eluting balloon for a balloon catheter. The drug eluting balloon comprises a balloon body (100) and a coating (200), and the coating (200) comprises a water-soluble adhesive layer (210), an isolating layer (220) and a drug layer (230) from the inside out. After the drug eluting balloon is pushed to a diseased part, the balloon body (100) is expanded, and the water-soluble adhesive layer (210) dissolves due to scouring by a blood flow, such that the isolating layer (220) and the drug layer (230) are separated from an outer surface of the balloon body (100) and adhere to a blood vessel wall. The provision of the isolating layer (220) can effectively suppress the water-soluble adhesive layer (210) from removing part of the drug layer (230) during dissolution, and after the drug layer (230) adheres to and makes contact with the blood vessel wall, the isolating layer can also reduce the scouring effect on the drug layer (230) by the blood flow, thereby reducing the loss of drugs, allowing the drugs to be taken in by the blood vessel wall to the greatest extent, greatly improving the utilization rate of the drugs and improving the treatment effect while also preventing toxic and side effects brought about by large doses of the drugs. Moreover, the isolating layer (220) can also realize the slow release of the drug layer (230), such that the drug layer (230) can provide treatment for a long time, and a good treatment effect can be obtained.
