The invention relates to a drug-coated balloon catheter which has a catheter balloon mounted on its distal end and an expansion protection surrounding the same. The invention is characterized in that the catheter balloon is protected from premature expansion even under strong mechanical stress and in that the catheter balloon folds back more easily after dilation.

Controlled expansion balloon catheter

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.

Pharmaceutical-coated medical products, the production thereof and the use thereof

For selective treatment of diseased tissue sections or organ parts, the surface of medical devices entering into contact with areas thereof under pressure is coated with lipophilic substantially water-insoluble medicaments binding to various tissue components with good adherence thereto, said medicaments having an effect thereupon a short time after entering into contact therewith without exerting a harmful influence upon adjacent healthy tissue.

Medical device for dispersing medicaments

The invention relates to a preparation for restenosis prevention. The preparations for restenosis prevention known as yet do not reach sufficient active agent concentrations in the affected sections of the vascular walls as higher doses cause undesirable side effects. The present invention is a preparation to which at least one antihyperplastic agent is added that has a distribution ratio between butanol and water .gtoreq.0.5. The lipophilic active agent is absorbed by the vascular wall fast and in sufficient quantity. The preparation may be a liquid that can pass through capillaries and may contain a contrast agent so that the active agent is transferred into the vascular wall without any additional effort while the usually required contrast radiograms are taken. The preparation may also be applied to a catheter.

Preparation for restenosis prevention

The present disclosure relates to balloon catheter medical devices. Some balloon catheter medical devices may include a balloon surface having paclitaxel embedded in a low-molecular weight matrix substance adhered thereto and dried. The dried paclitaxel may be immediately releasable after coming into contact with tissue. Other balloon catheter medical devices may include a balloon surface having a lipophilic proliferation inhibitor, an inflammation inhibitor, or an antioxidant adhered thereto.
