An apparatus and method for mastopexy surgeries correcting a ptosis condition caused by tissue stretching, in the breast as a result of pregnancy, time, aging, and the effects of gravity and athletic activity provide an implant having homogeneously formed connectors extending from inside an implant wall for anchoring to the chest wall or chest muscles of a patient. Embedded reinforcements and anchoring tabs or sutures may be readily oriented along a rib or other defining physiological location in order to provide immediate, permanent, and symmetric installation of implants in a mastopexy reconstruction.

A removable integrated target-illuminating device holder and grip apparatus and method thereof are disclosed. The apparatus mounts to an existing forestock of a weapon with an interference fit actuated by a single screw. The apparatus also includes a passage for receiving the barrel of a target illumination device. Resilient prongs are provided adjacent the rear of the passage to press the illumination device longitudinally along approximately the same axis as the weapon's barrel to prevent dislodgment upon movement of the weapon during handling or discharge, and to enable relatively quick, one-handed release and replacement of the entire illumination device.

The invention relates to devices and methods for reforming tissue surrounding the airway of a subject suffering from obstructive sleep apnea so as to open the airway and alleviate the occurrence of apneic events. Devices comprise a combination of resiliently deformable material and bioerodible material. The deformable portion of the device has a preferred shape that corresponds to the desired final shape of the device once placed in an airway. In making a transplant-ready device, however, the deformable portion is placed into a deformed shape and constrained in that shape by the bioerodible material. After implantation, the device gradually assumes the preferred shape as the constraining bioerodible material erodes. As the device gradually reforms toward the preferred shape, it reforms the tissue into the therapeutically desirable configuration. The gradual nature of the shape change generally stabilizes the device in the tissue, and supports tissue reforming into a stable configuration.

Known devices for contactlessly guiding or treating continuous lines of material (1) have one chamber (2). A supply device (3) for a gaseous fluid is connected to said chamber (2), which has a gas-permeable wall (4). The outer surface (5) of said wall (4) is embodied as a guide surface for the line (1). According to the invention, the gas-permeable wall (4) is produced from a porous, metal-containing material with open pores which have an average diameter of less than 500 mum, preferably less than 100 mum, especially less than 20 mum. The porous material used for the guiding surface enables the line (1) to glide on a fluid pad of less than 1 mm. The losses of fluid on the surfaces not covered by the line (1) are very low.

A portable stove includes a frusto-conical body and a grid carried within the body together with an optional cooking surface for the smaller end of the body and stands to elevate the larger end of the body to facilitate establishing an air flow into the body. By rolling a flat piece of metal that has folds on both ends until the folded ends are interlocked, the stove's body is formed. Squeezing the formed body releases it to return to a flattened configuration for storage. The components of the stove can thus be stored in a compact configuration such as in a backpack. An optional oven includes a cooking chamber within a housing. The oven rests on the body and redistributes heat from the burning fuel inside the body to the cooking chamber base, body and lid so that it bakes evenly. The housing confines the heat to the chamber for improved cooking efficiency.

A method of using a substantially non-porous equine collagen foil to repair and regenerate dura mater tissue of mammals when the dura mater tissue is damaged as a result of injury, tumors, surgery, and the like. The non-porous equine collagen foil comprises collagen fibrils which provides a replacement dura mater composition that is elastic, liquid-tight, and which has a high tensile strength. The non-porous equine collagen foil is furthermore resorbable and provides a biomatrix, wherein a neodura is rapidly formed which becomes indistinguishable from the autologous dura mater in a matter of weeks. The process for making the equine collagen foil reduces the likelihood of disease transmission.

In a method of manufacturing a semiconductor device which method is made up of a process of forming a wiring groove using a hard mask, a metal hard mask 107 is used to form a wiring groove 111, allowing the shape of the wiring groove 111 to be stabilized. Furthermore, a part or all of the metal hard mask 107 is removed before the formation of TaN and Cu layers in the wiring groove 111. This enables a reduction in possible damage, which may increase the dielectric constant of the surface of low-dielectric-constant film, and thus in possible inter-wire leakage current. As a result, a reliable semiconductor device can be provided.
