Claims

2026205274   03 Jul 20261                               CLAIMS2 We claim:3   1. A method for performing an IUD placement in a uterine cavity comprising:4          positioning an everting balloon system adjacent to a cervical canal, wherein the5 everting balloon system comprises:6                    a first catheter;7                  an everting balloon attached to the first catheter, and wherein the first catheter8          has a catheter lumen and a distal port at the distal end of the catheter lumen; and9                  a delivery catheter attached to an opposite end of the everting balloon from the10           first catheter; and11          everting the everting balloon in the cervical canal, wherein the everting comprises12 pulling the first catheter distally through the cervical canal, wherein the first catheter has an13 IUD device, and wherein the everting comprises inflating the balloon distal to the first14 catheter; and.15          deploying the IUD into the uterine cavity concurrent with the everting of the everting16 balloon, and wherein the deploying comprises using a pusher to release the IUD.1718   2. The method of claim 1, wherein the placement of the IUD device occurs after the extension19 of the everting balloon during the eversion process.2021   3. The method of claim 2, wherein the placement of the IUD device occurs with negative22 pressure with an aspiration source.2324   4. A method for performing an IUD delivery and placement procedure in a uterine cavity25 comprising:26          positioning an everting balloon system at the exocervix opening of the cervical canal,27 wherein the everting balloon system comprises:28                             a first catheter;29                          an everting balloon attached to the first catheter, and wherein the first30                  catheter has a catheter lumen and a distal port at the distal end of the catheter31                lumen; and32                         an outer catheter attached to an opposite end of the everting balloon33                   from the first catheter;2026205274   03 Jul 20261           everting the everting balloon in the cervical canal, wherein the everting comprises2   pulling the first catheter distally through the cervical canal, wherein the first catheter has an3   IUD, wherein the IUD is in a first configuration within the everting membrane, and wherein4   the IUD has a second configuration when the IUD extends beyond the everting membrane,5   and wherein when the IUD is in the second configuration, the IUD has a larger surface area6 than when in the first configuration.78   5. The method of claim 4, comprising releasing the IUD in combination with delivering9 negative pressure within the everting balloon.1011   6. The method of claim 5, wherein a pusher extends the IUD as the IUD is released in12 combination with negative pressure within the everting balloon.1314   7. The method claim 6, wherein the pusher is used for irrigation media during the IUD15 delivery and placement procedure.1617   8. A method for delivering and placing an IUD in a uterine cavity comprising:18          positioning an everting balloon system at the exocervix opening of the cervical canal,19 wherein the everting balloon device comprises:20                    a first catheter;21                  an everting balloon attached to the first catheter, and wherein the first catheter22          has a catheter lumen and a distal port at the distal end of the catheter lumen; and23                  an outer catheter attached to an opposite end of the everting balloon from the24            first catheter;25          everting the everting balloon in the cervical canal, wherein the everting comprises26 pulling the first catheter distally through the cervical canal, wherein the first catheter has an27 IUD in a collapsed state within the everting balloon.2829   9. The method of claim 8, further comprising collecting tissue performed by a fixed biopsy30 device on a specific location in a body of a patient by the location of the membrane on the 31 exterior surface of the everting membrane.
