First Claim
1. A method of tissue penetration and/or shaping of channels in tissue, or connections between tissue compartments in a body portion by means of a medical device for canalization thereof by penetration thereof, said method comprising:
- delivering said medical device in a delivery catheter to said body portion;
pushing a rear end of said medical device initially out of a distal end of said delivery catheter, whereby said medical device turns around a distal end of said delivery catheter, expands, engages with said tissue, and pulls itself by means of its own force out of said delivery catheter, digging and/or cutting into said tissue and turning itself outside in, and advancing into said tissue.

Abstract
A medical device for canalization of a tissue of a body portion by penetration thereof, a kit, a manufacturing method and a method of canalization are disclosed. The device is adapted for trans-catheter delivery to the body portion, and 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.
