Problems solved by technology

[0004] Although catheters help manage potential side effects of ablation procedures, the use of catheters is very uncomfortable for patients and entails multiple risks and disadvantages such as discomfort, risk of infection, accidental removal, etc.
Available catheters address the problems encountered with the use of hydrophilic coatings and / or antimicrobial silver coatings, but do not change the basic philosophy behind the use of Foley catheters after ablative benign prostatic hyperplasia (BPH) surgery

Embodiment Construction

[0036] figure 1 is a diagram illustrating some features of male human anatomy. Specifically, a bladder is shown. The urethra extends from the bladder including the prostatic urethra through the prostate. The location of the bladder neck and urethral sphincter are also shown.

[0037] Also refer to figure 2 , shows a side view of an example embodiment of an apparatus 10 including the features described below. Although features will be described with reference to the example embodiments shown in the drawings, it should be understood that features may be embodied in many alternative forms of embodiments. In addition, any suitable size, shape or type of elements or materials could be used.

[0038] In this example, device 10 is a stand. More specifically, in this example embodiment, device 10 is a urethral stent configured to be inserted into a patient's urethra. Also refer to Figure 3 to Figure 4 , the stent 10 includes a first member 12 forming a first layer and a seco...

Abstract

An apparatus including a first layer, where the first layer includes a scaffold structure forming an inner lumen along a length of the scaffold structure, and where the first layer includes a bioresorbable material; and a second layer on the first layer, where the second layer includes a bioresorbable material, wherein the second layer surrounds a majority of the first layer, and where the secondlayer is configured to hydroscopicly swell.

Description

technical field [0001] The exemplary and non-limiting embodiments relate generally to urology and, more specifically, to stents. Background technique [0002] Ablative benign prostatic hyperplasia (BPH) surgery involves transurethral resection of tissue, which results in destruction of the urethral wall within the area of ​​the ablated prostate. Destruction of this area creates swollen and irritated tissue, and it is necessary to coagulate open blood vessels. This is a source of postoperative bleeding, urethral irritation, urinary tract infection (UTI), bladder neck constriction (BNC), and obstruction. [0003] To manage these postoperative complications, the current standard of care is the placement of a Foley bladder catheter. Following the ablation procedure, a 2-way or 3-way Foley catheter is placed in the patient. In cases of severe bleeding during surgery, a three-way Foley catheter is used to allow for continuous postoperative bladder irrigation (CBI). Otherwise, ...
