摘要: Disclosed herein is a method of producing high purity pentagalloyl glucose (PGG), analogues or derivatives thereof, at least 99.9% pure, by washing with dimethyl ether. PGG may be provided in a kit, including a hydrolyzer for dissolving the PGG and a saline solution. Also disclosed herein is a device for delivery of a therapeutic solution to a blood vessel. The device may be a catheter having an upstream balloon and a downstream balloon. The upstream balloon may be expanded to anchor the catheter and occlude antegrade blood flow. The downstream balloon may be expanded to occlude retrograde blood flow, creating a sealed volume within the blood vessel. The downstream balloon may have pores configured to deliver a therapeutic inflation solution into the sealed volume or a portion thereof. The downstream balloon may be expanded by the expansion of a balloon disposed inside the downstream balloon.
