Embodiment Construction

[0016] Reference will now be made in detail to the preferred embodiments of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the specification to refer to the same or like parts.

[0017] exist image 3 Among them, the urethral stent 13 for the treatment of urethral stricture caused by prostatic hypertrophy includes a first stent part 11 and a second stent part 12 that use shape memory alloy wires to form a mesh barrel, and are arranged at a certain interval between the first and second stents One or more connecting wires 19 connecting the first and second stent parts.

[0018] Unexplained reference numeral 50 is a connecting hook, which is used to facilitate removal of the urethral stent 13 implanted in the prostate.

[0019] Here, the connecting wires 19 connecting the first bracket 11 and the second bracket 12 can not only use traditional connecting wires,...

Abstract

A urethral stent for the prostate including a first stent section placed into an upper portion of the urethra passing through the prostate, a second stent section placed into a lower portion of the urethra below a urinary sphincter muscle, the first and second stent sections being formed of a shape-memory alloy wire, and at least one connection filament is provided at a middle portion of the urethra passing through the urinary sphincter muscle so as to connect the first and second stent sections, thereby preventing the stent from moving to the upper or lower portions of the urethra.

technical field [0001] The present invention generally relates to a prostatic urethral stent, and in particular to a urethral stent for treating the condition that the urethra is compressed due to prostatic hypertrophy, so that the urethra is narrow and difficult to urinate. technical background [0002] In the prior art, a urethral stent 1 or a urethral dilating tube is inserted into the urethra to expand the urethra narrowed by prostatic hypertrophy. [0003] That is, first the urethral stent 1 is coated with silicon 2 or the like, and then placed in the urethra 2, thereby dilating the urethra 2 narrowed by prostatic hypertrophy and making the urethra easy to urinate. [0004] However, there is a problem with the urethral stent 1 placed in the urethra 2 that when the user urinates the stent can slide up or down to the bladder 6 away from its original placement. [0005] To solve this problem, such as figure 2 Tube 3 for dilating the urethra is used as shown. [0006] Th...
