Abstract

An intravaginal device has a working portion (e.g., intravaginal urinary incontinence device suppository, tampon) and an anchoring portion comprising at least one member extending beyond at least one end of the working portion to maintain the working portion in place during use.

Claims

1. A method of making an intravaginal stent comprising the steps of:

a) forming a working portion comprising a wire form having opposed working surfaces to provide support to an associated urinary system, wherein the wire form comprises an elastic material;

b) forming an anchoring portion comprising a wire form capable of maintaining the working portion in place during use, wherein the anchoring portion comprises at least one looped member extending longitudinally beyond at least one end of the working portion and returning to the working portion;

c) attaching a withdrawal mechanism to the stent;

d) enclosing the stent within a sheet-like material; and

e) placing the enclosed stent in an applicator for delivery into the vagina.

2. The method of claim 1, further comprising the step of enclosing the wire form of each of the working portion and anchoring portion within a biocompatible material.

3. The method of claim 1, further comprising the step of attaching a pad to each of the working surfaces.

4. The method of claim 1, wherein the working portion has a first use equivalent diameter of at least about 15 mm under an expansion pressure of 20 cm H₂O and a second use equivalent diameter of about 5 to about 25 mm under an expansion pressure of 100 cm H₂O wherein the second use equivalent diameter is less than the first use equivalent diameter.
