A deployment device for deploying a self-expansible medical implant at a target location in a body cavity, is provided. While generally, the expansion of self-expansible structures tends to be abrupt, and the impact of expansion may cause injury, a two-stage expansion process of the present invention minimizes the impact of exapnsion. Additionally, an ability to manuever the medical imlant into position, after the first stage of expansion, provides for accurate positioning. Thus the present invention is of a deployment device for precise and well-controlled manner of deployment, so as to minimize damage to the cavity wall and to position the implant accurately at the target location. The deployment device includes: an inner tube; an outer tube; and an implant received on the inner tube and enclosed by the outer tube. The implant has a self-expansible anchoring element which is in a contracted condition when enclosed by the outer tube, expands to a partially-expanded condition when the outer tube is retracted, and expands to a fully-expanded condition when the inner tube is removed.. The implant is deployed by introducing the deployment device to the target location in the body cavity; retracting the outer tube with respect to the implant such that the anchoring element self-expands from its contracted condition to its partially-expanded condition; and withdrawing the inner tube from the implant such that the anchoring element self-expands from its partially-expanded condition to its fully-expanded condition to firmly fix the implant at the target location within the body cavity.

A bone implant (10) is implanted in a cavity parallel to an implant axis (I) and without substantial rotation. The implant includes, on an implant portion to be implanted, cutting edges (14), which do not extend in a common plane with the implant axis and are facing toward the distal end of the implant. The implant also includes surface ranges (16) of a material that is liquefiable by mechanical oscillations. The cutting edges (14) are dimensioned such that they are lodged in the cavity wall after implantation. For implantation, the implant is impinged with mechanical oscillations, resulting in the thermoplastic material being at least partially liquefied and pressed into unevennesses and pores of the cavity wall to form a form-fit and / or material-fit connection between implant (10) and cavity wall, when re-solidified. The cutting edges (14) anchor the implant in the cavity wall.

An assembly structured to introduce a trocar or other medical instrumentation into a body cavity through an entry site formed in the cavity wall. The introducer assembly includes a base formed of a semi-rigid, flexible and / or a semi-flexible material having an instrument receiving passage extending there through, and further including an exterior sealing surface extending between proximal and distal portions of the base. The sealing surface has a predetermined configuration which is shaped to conform to the shape of the entry site as the base passes into the entry site. A fluid restricting seal is thereby established between the exterior of the base and the peripheral tissue surrounding the entry site, particularly when the entry site is formed by an incision commonly utilized an open laparoscopic procedure.

A high-span anchoring system is described for a cavity wall incorporating a wall reinforcement combined with a wall tie which together serve a wall construct having a larger-than-normal cavity. Further the various embodiments combine wire formatives which are compressively reduced in height by the cold-working thereof. Among the embodiments is a veneer anchoring system with a low-profile wall tie for use in a heavily insulated wall. The compressively reduced in height wall anchors protrude into the cavity through the seams, between insulation strips, which seams seal thereabout and maintain the integrity of the insulation by minimizing air leakage. Further, the eye wires extend across the insulation into the cavity between the wythes, and each accommodates the threading thereinto of a wire facing anchor or wall tie with either a pintle inserted through the eye or the open end of the veneer tie. The veneer tie is then positioned so that the insertion end is embedded in the facing wall. The close control of overall heights permits the mortar of the bed joints to flow over and about the wall reinforcement and wall tie combination inserted in the inner wythe and insertion end of the wall in the outer wythe. Because the wire formatives hereof employ extra strong material and benefit from the cold-working of the metal alloys, the high-span anchoring system meets the unusual requirements demanded thereof.

A semiconductor flipchip package includes a central cavity area on the first major side for receiving a flipchip die therein. The package substrate is substantially made from a single material that serves as the support and stiffener and provides within the cavity floor all the connecting points for flipchip interconnection to the silicon die. The integral cavity wall serves as a stiffener member of the package and provides the required mechanical stability of the whole arrangement without the need for a separate stiffener material to be adhesively attached. The cavity walls may contain extra routing metallization to create bypass capacitors to enhance electrical performance. Optional methods to cover the silicon die enhance thermal performance of the package.

In the present invention, an etching hole 21 is formed in a polysilicon film 14 as a cavity-wall member. Through the etching hole 21, hydrofluoric acid is injected, so as to dissolve a silicon oxide film 13, thereby forming a cavity 22. In the cavity 22, a detecting unit 12 of a sensor is in an exposed condition. Next, by sputtering, an Al film 16 is deposited in the etching hole 21 and on an upper face of a substrate. Thereafter, a portion of the Al film 16 positioned on the polysilicon film 14 is removed by etching back, thereby leaving only a metal closure 16a of Al which closes the etching hole. The sputtering step is performed under a pressure of 5 Pa or less, so that the pressure in the cavity can be held to be low.
