NOVEL INTRA UTERINE DEVICE
First Claim
1. A device positionable within the uterine cavity comprising a wire having two free ends and at least two loop-like structures formed between said free ends, wherein a first loop is approximately perpendicular with, and positioned through, a second loop thereby forming a three dimensional structure capable of elastically contracting and expanding in response to contraction and expansion of the uterine cavity.

Abstract
The present invention discloses an Intra Uterine Ball (IUB) device useful for a gynecological procedure or treatment. The aforesaid device comprises a hollow sleeve for at least partial insertion into the uterine cavity; and, an elongate conformable member with at least a portion comprised of shape memory alloy. The elongate member is adapted to be pushed out from said sleeve within said uterine cavity. It is the core of the invention that the elongate member is adapted to conform into a predetermined three dimensional ball-like configuration within said uterine cavity following its emergence from said sleeve, such that expulsion from said uterine cavity, malposition in said uterine cavity, and perforation of the uterine walls is prevented.

7. A method of positioning a device in a uterine cavity comprising:
-
(a) providing a device formed from a wire having two free ends and at least two loop-like structures between said free ends, wherein a first loop is approximately perpendicular with, and positioned through, a second loop thereby forming a three dimensional structure capable of elastically contracting and expanding in response to contraction and expansion of a uterine cavity; and (b) pulling a free end of said two free ends through a delivery sleeve thereby linearizing the device; and (c) positioning one end of said delivery sleeve at an opening to said uterine cavity and delivering said wire into a uterine cavity to thereby form said three dimensional structure in said uterine cavity. - View Dependent Claims (8, 9, 10, 11)
