摘要:
This present invention concerns a new combination of balloon catheters and formulations containing active substances that adhere to the surface of the balloon membrane. Furthermore the present invention concerns coating processes for the manufacture of these balloon catheters as well as their use in the treatment and prophylaxis of vascular diseases.
摘要:
The present invention is related to scoring or cutting balloon catheters carrying at least on a portion of their surface at least one drug or drug preparation and at least one lipophilic antioxidant at a ratio of 3-100% by weight of the at least one lipophilic antioxidant in relation to 100% by weight of the drug, wherein a combination of the at least one drug being a limus drug and the at least one lipophilic antioxidant being butylated hydroxytoluene is excluded.
摘要:
The present invention relates to a drug-eluting medical device, in particular a balloon for angioplasty catheters with drug elution to prevent the restenosis of the vessel subjected to angioplasty. More particularly, the present invention relates to a catheter balloon completely or partially coated with paclitaxel in hydrated crystalline form or in hydrated solvated crystalline form, having an immediate release and bioavailability of a therapeutically effective amount of paclitaxel at the site of intervention. The balloon can be made of a polyether-polyamide block copolymer, or a polyester amide, or polyamide-12.
