Medical product with a particle-free coating releasing an active substance

Abstract

Embodiments described herein concern medical products, which come into contact with the organism, such as short-term implants and long-term implants, coated with at least one layer, containing a molecular-disperse distributed or dissolved active substance in at least one carrier and optionally one or more adjuvants, wherein the at least one layer forms a stably spreadable solution, methods for making this coating of stably spreadable solution and use of the medical products coated with the stably spreadable solution.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention concerns medical products, which come into contact with the organism, such as short-term implants and long-term implants, coated with at least one layer, containing a molecular-disperse distributed or dissolved active substance in at least one carrier and optionally one or more adjuvants, wherein the at least one layer forms a stably spreadable solution, methods for making this coating of stably spreadable solutions and use of the medical products coated with the stably spreadable solution.[0003]2. Description of the Relevant Art[0004]In the past, improvements concerning balloon catheters related primarily on their ability to place a stent precisely and safely. The PTCA as an independent method was—and is still—used primarily to remove existing stenosis by temporary dilatation and thereby widening of the vessel, but was largely replaced in the coronary field by stent implantation as permanent vesse...
