PROBLEM TO BE SOLVED: To provide a device and method of a stent used for a urinary tract procedure. An apparatus comprises a first layer, the first layer comprising a skeletal structure, forming internal lumens along the length of the skeletal structure, and a bioabsorbable material. A second layer above the layer, with a bioabsorbable material configured to expand so that the ends of the first layer extend beyond the ends of the second layer. Includes a second layer, positioned above the first layer, and an expandable balloon located within the distal end of the inner lumen of the first layer. [Selection diagram] Fig. 2 |
