Abstract: The conduit device (1) is intended for conducting a fluid from a fluid source to a recipient. A tubular portion (2) of the conduit device has an inner side that is intended for contact with the fluid. Means are provided for adapting the surface tension of the inner side of at least the tubular portion and/or the fluid.

Abstract: The invention provides a medical device such as a catheter having in a proximal end a braided portion being operable between two configurations, one for insertion of the device into the body and one for retaining the catheter in the body. To reduce ingrowth of body tissue, the braided portion comprises two parts, a first part forming paths for a body liquid, e.g. urine, to be drained from the body through the device to a place of disposal, and a second part having a structure which counteracts cell adhesion better than the first part. During use, the first part is drawn into the second part whereby the cells are separated from first part by the second part and therefore ingrowth of body tissue is reduced or avoided completely. The invention further provides a method of making a device with a braided portion and being improved with respect to ingrowth of body tissue.
