A tissue expander and a method of making a tissue expander which includes (a) a fluid-tight envelope which is inflatable by a single means for inflation and which has an expandable upper section formed (i) a first elastic portion and (ii) a second elastic portion formed of a material having a lower modulus of elasticity than that of the material forming the first portion, so that during the inflation of said envelope the modulus of elasticity of each portion at least partially controls the amount of expansion of each portion, thereby allowing the envelope to assume a complex shape. The tissue expander also has a means for inflating the envelope with a biocompatible fluid.

A suspension system for rejuvenation of a human midface, the suspension system including a first suture material having a first end attached to a first needle, a second end attached to a second needle, and a first primary anchor graft having a plurality of openings through which the first suture material is inserted. The first primary anchor graft may be positioned to be about equidistant between the first end and the second end of the first suture material. The suspension system is adapted to be locatable within the human midface so as to elevate at least one malar fat pad and the first suture material may include a plurality of resistance members located on either side of the first anchor graft. The suspension system may further include a secondary braided suture attached to the first and second needles, and a guide suture inserted through the first primary anchor graft.

An instrument for subcutaneously inserting an injection reservoir attached to an inflatable prosthesis by means of an elongated fluid conduit is disclosed. The instrument has a hollowed end which holds the injection reservoir to be inserted in a mating, releasable fashion and that end is attached to a handle for guiding the hollowed end to the desired site. Desirably, but optionally, the end of the handle of the instrument is provided with a shaped tapered portion to act as a dilator to create a subcutaneous pocket prior to insertion of the injection reservoir.

Described herein is an improved injection reservoir of the type which is employed to permit subcutaneous inflation of inflatable, implantable prostheses such as tissue expanders. The improved injection reservoir has a lozenge shape when viewed from above which permits this injection reservoir to be more easily inserted and removed subcutaneously. In a more preferred embodiment, the injection reservoir has a low profile shape such that its height is no more than forth percent of its width.
