Urinary stent
First Claim
1. A urinary stent comprising an elongate member, the elongate member defining a lumen extending from a proximal end to a distal end of the elongate member, the proximal end comprising a proximal tip configured to be disposed within a prostatic portion of a urethra of a patient, the proximal end comprising a first arm and a second arm disposed opposite the first arm, the first and second arms defining an opening at the proximal tip of the proximal end, the first and second arms being biased in an expanded configuration in which the opening has a diameter that is substantially equal to an outer diameter of a remaining portion of the elongate member, and movable into a collapsed configuration in which the diameter of the opening is smaller than the outer diameter of the remaining portion of the elongate member.

Abstract
A urinary stent includes an elongate member that defines a lumen extending therethrough and that is configured to be disposed at least partially within a prostatic portion of a urethra of a patient. The elongate member includes a collapsible portion disposed at a proximal end portion of the elongate member. The collapsible portion has a first configuration in which an outer perimeter at a proximal end of the collapsible portion is substantially equal to an outer perimeter of a remaining portion of the elongate member and a second configuration in which the outer perimeter at the proximal end of the collapsible portion is smaller than the outer perimeter of the remaining portion of the elongate member.

6. A urinary stent, comprising:
-
an elongate member defining a lumen extending from a proximal end to a distal end of the elongate member, the proximal end comprising a proximal tip configured to be disposed within a prostatic portion of a urethra of a patient, the proximal end comprising a first arm and a second arm disposed opposite the first arm, the first and second arms defining an opening at the proximal tip of the proximal end, the opening in fluid communication with the lumen, the first and second arms being biased in an expanded configuration in which the opening has a first diameter that is substantially equal to an outer diameter of the remaining portion of the elongate member, and movable into a collapsed configuration in which the diameter of the opening is smaller than the outer diameter of the remaining portion of the elongate member; and a second portion extending from the distal end of the elongate member and configured to be disposed at least partially within a bladder of the patient. - View Dependent Claims (7, 8, 9, 10)
