Abstract
Catheter devices provide for rolling movement between the inner and outer catheter tubes with a roller assembly in a radial gap between the inner and outer catheter tubes. Devices of the invention are particularly useful in minimally invasive implantations, such as the implantation of a vascular implant. A particular application is interventional catheter-assisted aortic valve implantation.
