Methods, devices and systems facilitate retention of a variety of therapeutic devices. Devices generally include an anchoring element, which has been designed to promote fibrotic ingrowth, and an anchored device, which has been designed to firmly engage the complementary region of the anchoring element. The anchoring element may be placed in a minimally invasive procedure temporally separated from the deployment of the anchored device. Once enough time has passed to ensure appropriate fixation of the anchoring element by tissue and cellular ingrowth at the site of placement, the anchored device may then be deployed during which it firmly engages the complementary region of the anchoring element. In this manner, a firm attachment to the implantation site may be made with a minimum of required hardware. Some embodiments are delivered through a delivery tube or catheter and while some embodiments may require laparoscopy or open surgery for one or more of the placement procedures. Some embodiments anchor devices within the cardiovascular tree while others may anchor devices within the gastrointestinal, peritoneal, pleural, pulmonary, urogynecologic, nasopharyngeal or dermatologic regions of the body.

A support contour of a cushion, such as a wheelchair cushion, defines relief areas at locations adjacent to skin covering the ischial tuberosities, the greater trochanters and the coccyx and sacrum of a person sitting on the support contour. Support areas of the support contour transfer force into the pelvic area adjacent to skin covering tissue masses on opposite lateral sides of the posterior buttocks and beneath the proximal thighs of the person. Greater clearance is also provided in the perineal area. Risks of pressure ulcers from pressure and shear forces on bony prominences is reduced while providing support at the broader areas without bony prominences in such a manner to encourage postural alignment. The risks of skin breakdown perineal are diminished.

A device used to treat heart disease by decreasing the size of a diseased heart, or to prevent further enlargement of a diseased heart. The device works by limiting the volume of blood entering the heart during each cardiac cycle. The device partitions blood within the heart, and protects the heart from excessive volume and pressure of blood. The device is placed within the interior of the heart, particularly within a ventricular cavity. The device is a hollow sac, with two openings, which simulates the shape and size of the interior lining of a ventricle of a normal heart. It allows the ventricle to fill through one opening juxtaposed to the annulus of the inflow valve to a predetermined, normal volume, and limits filling of the heart beyond that volume. It then allows blood to be easily ejected through the second opening through the outflow valve. By limiting the amount of blood entering the ventricle, the ventricle is not subjected to the harmful effect of excessive volume and pressure of blood during diastole, the period of the cardiac cycle when the heart is at rest. This allows the heart to decrease in size, or to reverse remodel, and to recover lost function. In some applications, a second device may be simultaneously placed inside the heart to take up excessive space between the heart and the primary device.

A laptop computer carrying case transforms into a desktop for use of a laptop or similar electronic device having a keyboard and a hingeably openable display. The laptop key board is held by bands in the lower portion of the case and the display is held in the top section of the case. Hinge structures are provided on the left and right sidewalls of the bottom section of the case. When the hinge structures are pivotally angularly separated, the bottom section containing the keyboard will be substantially horizontal enabling use of the laptop in a standing or mobile position. When the laptop is not being used, the case may be closed and the hinge structures closed with the laptop being carried by the strap over the shoulder. The hinge structure is provided with structure for limiting the amount by which the arms of the hinge may be pivotally angularly separated thereby providing stability to the laptop case in the desk top position. Detent means is provided to hold the arms of the hinge structure in aligned position when the case is being used to carry the laptop.

Tubular, especially can-shaped, receptacle for the accommodation of fluids, especially drinks, with a tubular body and a base and top section attached to this, wherein the top section is constructed in the shape of a shoulder and is suitable for attaching a closure device, especially a resealable one. The shoulder-shaped top section is at least partially enclosed, especially in the shape of a shoulder, by an upper edge of the tubular body and sealed with this.

In order to provide a lumbar support which conforms to the curve of the spinal column so as not to give a feeling of incompatibility or other unpleasant feeling, and is easily adjusted to meet a user's preference, a lumbar support 10 of the present invention is structured such that a bulging member 30 provided with two housing parts 31 and 32 to house a cushioning material for adjustment 34 is fixed on the back surface of a flexible plate 20, which is incorporated so that the front surface of the flexible plate 20 is positioned to the front surface side of a back cushion 120. Accordingly, the curvature of the two housing parts 31 and 32 does not affect a feeling of contact with the waist as it is, but works as a feeling of contact with larger curvature owing to the flexible plate 20, which results in suppression of pressure on the nervous system between the third and fourth lumbar vertebrae. Furthermore, by setting the width of a border region 33 between the two housing parts 31 and 32 in an appropriate range, it is possible to suppress a feeling of pressure on such a nervous system, and at the same time, to suppress any feeling of incompatibility or other unpleasant feeling caused by too large a curvature.

A test device has been invented for determining three-dimensional consolidation properties of soils, using a flexible ring permitting displacements and dissipation of the excess pore pressures in both horizontal and vertical directions, and affording determination of coefficients of consolidation in the horizontal and vertical directions, and the modulus of elasticity. The flexible ring consists of a filter fabric around the soil specimen, a rubber membrane around the filter, circular shaped segmented metal plates around the membrane and rubber bands or rings around the plates. Both the incremental loading or triaxial type loading systems can be used with this device. A calibration device for calibration of the flexible ring is used to determine the modulus of elasticity of elastic elements, required for calculating lateral resistance provided by the flexible ring during the test.

For attaching a cardiac stimulator lead at a desired position inside a heart, the stimulator lead having a flexible tube from which a helix is extendible at a distal end thereof by a screw rotating motion and having a proximal end interconnected with an operating member, a tool has a flexible portion wire with an engagement formation at a distal end thereof that mates with a complimentary engagement formation at a proximal end of the operating member. The tool has a handle containing an internal cavity, with a proximal portion of the torsion wire being rotationally rotated by the handle in the internal cavity, and a resilient yoke is formed in the internal cavity, with at least a part of the yoke engaging grooves and ridges in a circumferential boundary surface of the internal cavity.

A faucet end piece connectable to a faucet nozzle is provided including a cylindrical body defining a cavity, a vertical pipe extending within the cavity, and an internal partition with water passages therethrough, extending across the cavity and connecting the vertical pipe to the body; a valve insertable in the cavity including a cap portion fitting over the vertical pipe and having at least one side orifice, a bore and a flange portion projecting transversally from the cap portion; a resilient element insertable inside the cavity between the body's internal partition and the valve flange portion. The valve is movable vertically under water pressure between an upper position wherein water flows through the cap portion side orifice, the bore and through the body vertical pipe, and a lower position where water flows around the cap portion through the internal partition water passages.

A planetary gear bearing arrangement, including a planet carrier provided with a fixed bearing axis on which a planet gear is rotatably mounted via a sliding bearing that has a first antifriction layer on the axis side and a second antifriction layer on the gear side, wherein one of the two antifriction layers (8, 11) is created on a surface (10, 19) which is at least partially domed in the sliding region to reduce the edge pressure.
