1. A urinary catheter, comprising:
- a catheter body having a proximal manipulation end and a distal treatment end, the catheter body including a drainage lumen defined between the proximal manipulation end and the distal treatment end, the catheter body further including a drainage aperture proximate the distal treatment end, the drainage aperture being fluidly connected to the drainage lumen; and
a clot prevention component mounted over the distal treatment end so as to cover the drainage aperture, the clot prevention component including a spring device including a spring body formed by a plurality of wound coils in adjacent relation, the entry points defined as spaces between adjacent wound coils, whereby a fluid can simultaneously enter the drainage aperture via the plurality of entry points, and whereby the fluid flows through the drainage lumen for removal of the fluid at the proximal manipulation end.

Abstract
An anastomosis device that includes a catheter body is provided. A distal end portion of the catheter can include a spring device to prevent the formation of blood clots and to improve the flow of urine out of the catheter. The device may be used, for example, in performing procedures such as a vesico-urethral anastomosis in association with a radical prostatectomy, or with an end-to-end urethral anastomosis.

6. An anastomosis device for use in a radical prostatectomy procedure, comprising:
-
a catheter body having a proximal manipulation end and a distal treatment end, the catheter body including a drainage lumen defined between the proximal manipulation end and the distal treatment end, the catheter body further including a drainage aperture proximate the distal treatment end, the drainage aperture being fluidly connected to the drainage lumen; and a flexible spring mounted over the distal treatment end so as to cover the drainage aperture, the flexible spring including a spring body defined by a plurality of adjacent wound coils, wherein a plurality of fluid entry points are defined along the spring body between adjacent wound coils, wherein a fluid enters the drainage aperture through the plurality of fluid entry points, whereby the fluid flows through the drainage lumen for removal of the fluid at the proximal manipulation end. - View Dependent Claims (7, 8, 9, 10)

11. A method for preventing clotting of a urinary catheter, comprising:
-
providing a catheter body having a flexible spring mounted over a drainage aperture located at a distal treatment end of the catheter body, the flexible spring having a spring body formed by a plurality of adjacently wound coils wherein fluid entry points are continuously defined between the adjacently wound coils; advancing the distal treatment end to a desired location within a patient'"'"'s urinary tract; and removing fluid from the desired location by introducing the fluid through the fluid entry points and into the drainage aperture, the drainage aperture fluidly connected to a drainage lumen within the catheter body that is fluidly connected to a proximal manipulation end. - View Dependent Claims (12, 13, 14, 15)
