A minimally invasive medical device is provided. The device comprises an elongated member with proximal and distal ends, an inner radially expandable body surrounding the distal end of the elongated member, a stent surrounding the inner body, and an outer radially expandable body surrounding the stent. Optionally, the medical device further comprises a haemostatic coating surrounding the outer body. A method for treating tissue is also provided. The method comprises placing an elongated device into the tissue to create a path, radially expanding the device against the tissue to radially displace the tissue along the path, radially reinforcing the device against the tissue, and introducing a medical element through the device to perform a medical procedure on the tissue that can be image guided. |
