An invention relating to a method for the delivery, or placement, of, for example, a voice prosthesis into a puncture. A flexible flange provided on an outside surface of the device is temporarily resiliently deflected into a delivery orientation so the device can be delivered. Once delivered, the retainer holding the flange in the delivery orientation is removed so the flange can extend out to the use orientation.

1. A method for inserting into a first opening in a human body a device including a device body having a longitudinal axis and a flexible first flange provided on an outside surface of the device body, the flange having a continuous radially-extending surface which extends radially outward from the body to a radial outer edge of the flange and having a deployed, use orientation in which it projects generally outwardly from the outside surface of the device body comprising resiliently deflecting the flange toward the axis of the device body and placing over the resiliently deflected flange a retainer of a material soluble in a fluid, inserting the device into the first opening, and permitting dissolution of the retainer. 2. The method of claim 1 further comprising contacting the retainer with the fluid. 3. The method of claim 1 wherein the first opening is a first opening in a wall having a first side and a second side, and further comprising pushing the device body, resiliently deflected flange first, from the first side into the first opening so that the resiliently deflected flange lies on the second side of the wall. 4. The method of claim 1 wherein the first opening is a first opening in a wall having a first side and a second side, and further comprising pulling the device body, resiliently deflected flange first, from the second side into the first opening so that the resiliently deflected flange lies on the first side of the wall. 5. A method for inserting into a first opening in a human body a device including a device body having a longitudinal axis and a flexible first flange provided on an outside surface of the device body and having a deployed, use orientation in which it projects generally outwardly from the outside surface of the device body comprising resiliently deflecting the flange toward the axis of the device body and placing over the resiliently deflected flange a retainer of a material soluble in a fluid, and inserting the device into the first opening, resiliently deflecting the flange toward the device body and placing over the resiliently deflected flange a retainer comprise inserting the device body into a second opening of an instrument, the second opening having a cross section slightly larger than a cross section of the device body transverse to its longitudinal axis so that contact with a wall of the second opening deflects the flange, placing the retainer over the deflected flange and removing the device body from the instrument. 6. The method of claim 5 wherein the first opening is a first opening in a wall having a first side and a second side, and further comprising pushing the device body, resiliently deflected flange first, from the first side into the first opening so that the resiliently deflected flange lies on the second side of the wall. 7. The method of claim 5 wherein the first opening is a first opening in a wall having a first side and a second side, and further comprising pulling the device body, resiliently deflected flange first, from the second side into the first opening so that the resiliently deflected flange lies on the first side of the wall. 8. A method for inserting into an opening in a human body a device including a resiliently deflectable device body having a substantially uniform insertion cross-section transverse to its longitudinal extent which is insufficient to fill the opening and a larger use cross section transverse to its longitudinal extent, the method comprising resiliently deflecting the device body into its substantially uniform insertion cross-section, placing over the resiliently deflected device body a retainer for retaining the device body in its substantially uniform insertion cross section, inserting the device with the retainer in place into the opening, and removing the retainer to permit deployment of the device body to its use cross section. 9. The method of claim 8 wherein placing over the resiliently deflected device body a retainer for retai ning the device body in its substantially uniform insertion cross section comprises placing over the resiliently deflected device body a retainer soluble in a fluid. 10. The method of claim 9 and further comprising introducing the fluid into contact with the retainer.
