摘要 |
A stent for introduction into a portion of a urethra in a body of a patient. The urethra extends through a prostate and is formed by a wall having a diameter. The stent includes a longitudinally-extending body made from a material adapted for absorption by the body of the patient. The longitudinally-extending body has an expanded condition in which the body has a predetermined diameter greater than the diameter of the portion of the urethra extending through the prostate. The longitudinally-extending body is formed with a plurality of coils along the length thereof adapted to engage the wall of the urethra when the longitudinally-extending body is in the expanded condition. The longitudinally-extending body is provided with spaces between the coils to permit the wall of the urethra to extend therein and serve to anchor the longitudinally-extending body to the wall. |
