Summary for Patent: 8,460,693
Title:Intraluminal device with a coating containing synthetic fish oil and a therapeutic agent
Abstract: The invention relates to an intraluminal device, in particular an intraluminal prosthesis, shunt, catheter or local drug delivery device. In order to increase the bio-compatibility of this device, it is provided with at least one coating. The coating contains a therapeutic agent which is comprised in a matrix that sticks to the intraluminal device. Instead of being formed by a little bio-compatible polymer, the matrix is formed by a bio-compatible oil or fat, such as cod-liver oil or olive oil. Preferably, the bio-compatible oil or fat further comprises alfa-tocopherol.
