Abstract
Abstract A relatively narrow diameter tubular inserter adaptable for use with a wide variety of intrauterine devices, having lateral slots therein for retaining a resilient intrauterine device in an undeformed state during shipment and storage prior to insertion. The intrauterine device is moved to a deformed state within the relatively narrow tube just prior to insertion, and ejected therefrom into its normal expanded state within the uterine cavity, whereupon the tube is withdrawn.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
67 words
A method of preparing a resilient intrauterine device for high fundal positioning in a uterine cavity comprising the steps of: partially housing said intrauterine device in an expanded, substantially undeformed configuration within a tubular inserter, rearwardly of a forward, expulsion end of said inserter; and moving said intrauterine device forwardly, toward the expulsion end of said inserter, into an elongate deformed attitude entirely within the tubular inserter.
Claim 2
Independent Claim
67 words
A method of preparing a resilient intrauterine device for high fundal positioning in a uterine cavity comprising the steps of: partially housing said intrauterine device in an expanded, substantially undeformed configuration within a tubular inserter, rearwardly of a forward, expulsion end of said inserter; and moving said intrauterine device forwardly, toward the expulsion end of said inserter, into an elongate deformed attitude entirely within the tubular inserter.
Claim 3
Dependent Claim
40 words
The method of claim 1 wherein the intrauterine device is positioned within a uterus by the further steps of inserting the tubular inserter into a cervical canal; and expelling the intrauterine device from the tubular member within a uterine cavity.
Claim 4
Dependent Claim
39 words
The method of claim 2 wherein the step of inserting the tubular inserter into a cervical canal includes the step of moving the tubular inserter to the fundus of a uterine cavity prior to expulsion of the intrauterine device.
Claim 5
Dependent Claim
63 words
The method of claim 3 wherein the step of expelling the intrauterine device from the tubular inserter includes the further steps of: introducing a plunger into the tubular inserter behind the intrauterine device housed within the tubular inserter; and drawing the tubular inserter over the plunger while the plunger is in a stationary position to expel the intrauterine device from the tubular inserter.
Claim 6
Dependent Claim
45 words
The method of claim 1 wherein said steps of partially housing an intrauterine device within a tubular inserter and moving said intrauterine device into an elongate deformed attitude within said tubular inserter are completed prior to insertion of said tubular inserter into a cervical canal.
