Improved prostheses comprising a tissue expander and a graft material are disclosed herein. Also disclosed are methods of making prostheses and methods of treatment using the prostheses.

Implantable prosthesis having acellular tissue attachments

A prosthesis comprising a tissue expander and one or more samples of graft material, wherein the tissue expander is attached to the one or more samples of graft material in a manner that allows the tissue expander and the one or more samples of graft material to be implanted in a patient as a unitary prosthesis; and wherein tissue expander is attached to the one or more samples of graft material in a manner that will allow the tissue expander and the graft material to separate after a period of time following implantation to allow removal of the tissue expander from an implant sites while leaving the graft material within the implant site, the prosthesis comprises a tissue expander having molded grooves, slots, channels, or other shallow cavity spaces on a surface, and wherein the graft material is within the grooves, slots, channels, or other shallow cavity spaces, securing the graft material to the tissue expander.

The present invention relates to applicators for inserting objects into body cavities, and to methods for making the same. The applicators are particularly useful for inserting catamenial and prophylactic devices into a vaginal canal. The applicators comprise a tubular insertion member and a retrofitted gripping member. The gripping member has an outer diameter greater than that of the insertion member. An interface is created due to this size differential, which provides a visual or tactile cue of applicator insertion depth, and thereafter object positioning within the body cavity. The gripping member comprises at least one raised area on its outwardly disposed surface, providing resistance to movement of the user's manual digit in response to longitudinal forces on the insertion member. Longitudinal forces are created during both the insertion step of use, as well as the expulsion step delivering the contained object from the insertion member into the body cavity.

Applicator for catamenial device having improved gripper end

The invention relates to a tampon applicator having a cylindrical outer sleeve and an inner sleeve, which is displaceable therein, is provided with an axial longitudinal slit and encloses a tampon. A tongue-shaped retention element is integrally connected to the outer sleeve so as to be bendable and projects through the longitudinal slit of the inner sleeve into the latter, and lies against the rear end of the tampon. When the inner sleeve is withdrawn out of the outer sleeve, the tampon is held in place by the retention element and transferred into the outer sleeve. The retention element is provided with one part of a locking mechanism (detent plate), the other part of which is formed by one of the two sleeves (longitudinal edges of the longitudinal slit of the inner sleeve. The aforesaid locking parts interact in such a way that the retention element is locked in its engaged position bent into the inner sleeve. The transfer of the tampon out of the inner sleeve into the outer sleeve is thereby ensured when the tampon applicator is utilized, and at the same time a simple, economic mass production of the tampon regulator is ensured.

Tampon applicator

A nonwoven web is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins. A baffle plate may be inserted into the mixing zone and acts to control the lateral or cross-sectional composition of a web formed by the fibers accumulated on the screen. When different fibrous materials are fed to the lickerin along their length, the vertical composition of the web is altered.

Transverse webber and stratified webs formed therewith
