Abstract
An implantable constriction device for treating an incontinent patient comprises an elongate composite structure adapted to constrict the urethra, urine bladder, anus, colon or rectum of the patient. The elongate composite structure is composed of a base material, such as hard silicone, making the composite structure self-supporting. Property improving means is provided for improving at least one physical property of the composite structure other than self-supporting properties, such as fatigue resistance, liquid impermeability, aggressive body cells resistance, anti-friction properties and lifetime.

- 1. An implantable constriction device for treating an incontinent patient, comprising an elongate composite structure adapted to constrict the urethra, urine bladder, anus, colon or rectum of the patient, wherein said elongate composite structure is composed of a base material making said composite structure self-supporting and property improving means for improving at least one physical property of said composite structure other than self-supporting properties.
- 53. An implantable constriction device for treating an incontinent patient, comprising an elongate composite structure adapted to constrict the urethra, urine bladder, anus, colon or rectum of the patient, wherein the composite structure includes an elongate biocompatible self-supporting base material having surfaces exposed to aggressive body cells, when the constriction device is implanted in the patient, and a cell barrier coating coated on said surfaces to prevent body cells from breaking down the base material.
