Abstract
A medical device for canalization of a tissue comprises a radially expandable and crimpable or collapsible substantially tubular member that has a rear end, a front end, and a pattern of struts or a mesh of wires arranged in-between the rear end and the front end, arranged around an interior of the device. The tubular member has extensions, which are arranged towards the interior of the device in a first state of the device, and towards an exterior of the medical device in a second state of the device, wherein the second state of the medical device is the tubular member turned inside out. During storage, the device is restrained in a delivery catheter in the second state. During delivery the device turns outside in and digs into the tissue to create a channel therein, thus preventing or fixating debris or other matter to spread from the channel.
