Embodiment Construction

[0033] see Figure 1a and 1b , constituting the first embodiment of the partial cuff 11 comprises a flexible base member 12, the base member is preferably made of a mesh synthetic fiber material, said mesh synthetic fiber material is used as for surgical repair of hernia and urethral sling Made of polypropylene strands. This type of mesh is biocompatible and accommodates tissue ingrowth through the interstices of the mesh.

[0034] Without limitation, when the device will be used to address female urinary incontinence, the mesh base member 12 may be generally oval or elongate in shape with a major axis of about 3 cm and a minor axis of about 1- 1 / 2cm.

[0035] In accordance with a first aspect of the invention, an expandable member 13 is attached to the flexible mesh base member 12, the expandable member 13 having a predetermined shape configuration and being generally centrally disposed on one major surface of the flexible base member 12. The expandable member 13 may compri...

Abstract

To increase the resistance to liquid and substance flow through a lumen of a tubular organ, a cuff comprising a flexible, mesh base member is appended to an exterior wall of the tubular organ such that it only partially surrounds the tubular organ. Ultimately, tissue ingrowth through the mesh base member integrates the cuff into the wall of the tubular organ. When the cuff is applied to the urethra of an incontinent patient, the increased resistance to flow renders the patient continent while still allowing normal voiding. The base member may also support an optional expandable component, e.g., a balloon-like element that can be selectively inflated and / or deflated to restrict the lumen of the tubular organ by a desired degree.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 011,750, filed January 22, 2008, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to surgically implantable flow restrictors and, more particularly, to a cuff that can be attached directly to a tubular organ for increasing the resistance to flow of fluids and substances through the tubular organ. Background technique [0004] Biological tubular organs in the human body are conduits for fluids, food, and waste. For example, the urethra is the conduit for urine between the bladder and the opening of the urethra, and it also acts as a barrier against incontinence. In the case of stress incontinence, a person inadvertently leaks urine when coughing or laughing. [0005] Stress urinary incontinence occurs mostly in women and can be managed with absorbents and surgical tr...
