A vascular occluding device for modifying blood flow in a vessel, while maintaining blood flow to the surrounding tissue. The occluding device includes a flexible, easily compressible and bendable occluding device that is particularly suited for treating aneurysms in the brain. The neurovascular occluding device can be deployed using a micro-catheter. The occluding device can be formed by braiding wires in a helical fashion and can have varying lattice densities along the length of the occluding device. The occluding device could also have different lattice densities for surfaces on the same radial plane.

A prosthesis for transluminal implantation consists of a flexible tubular interbraided structure of metal or polymeric monofilaments, and polymeric multifilament yarns. The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced apart helices, concentric on a common central axis of the prosthesis. The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide a sheeting that occupies interstices between adjacent structural strands, to reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft. An alternative embodiment prosthesis includes elastically and plastically deformable structural strands, selectively plastically deformed by cold-working then interbraided to form the prosthesis.

A disposable cover for use with a remote control device for providing a protective barrier to human infection comprising a front member having a continuously flat surface and a rear member integrally molded in a seamless unitary, one-piece construction with the front member at a plurality of rounded surfaces for forming a single-use, disposable protective enclosure. An orifice is formed in and parallel to an oblong dimension of the rear member for enabling most any size remote control device to be inserted into and removed from the enclosure. The rounded surfaces designed into the disposable cover facilitate the closing of the orifice for enclosing the remote control device. The front member, rear member and rounded surfaces are each comprised of a flexible, stretchable and transparent material for conforming to the shape of the remote control device and for providing a disposable, protective sanitation barrier to human infection.

The present invention comprises methods and compositions for delivery devices. More particularly, the present invention comprises methods and compositions for devices comprising a matrix comprising a polymer network and a non-gellable polysaccharide having oxygen and optionally active agents incorporated therein. The matrix may be formed into any desired shape for treatment of compromised tissue or for delivery of oxygen to a localized environment.

A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

Described herein are flexible implantable devices or stents that can, for example, navigate tortuous vessels of the neurovasculature. The devices can also conform to the shape of tortuous vessels of the vasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Methods and structures are provided for adjusting, along a length of the device, the porosity of the device while maintaining a cross-sectional dimension. In some embodiments, a distal stent cover covers the distal end of the device and reduces friction between the stent and an inner surface of a delivery device, such as a catheter.

A moisture sensor for skin is disclosed. With the moisture sensor, a user can determine that her skin is too dry, and can conveniently apply a skin-care product. In addition, in one embodiment, the sensor can assist in identifying different types of skin-care products to apply. As one example, a skin-care product is a type of lotion. As another example, a skin-care product is a type of shampoo.

A sanitary napkin in which diffusing liquid hardly reaches a rear end edge is adapted to make a liquid absorbent layer less deformable in a rear region so that it can easily be kept in close contact with the wearer's buttocks. The sanitary napkin has an elongated main absorbent region surrounded by compressed grooves that are formed in a skin-side surface. Since a rear end of the main absorbent region is far away from a rear end edge of the napkin to provide a relatively large rear region, worries about rearward leakage may be relieved. Furthermore, since auxiliary longitudinal grooves are provided in the rear region, a liquid absorbent layer may hardly be twisted.

Disclosed is an absorbent article including a backsheet, an absorbent storage layer, a liquid guide layer, and a top layer. The absorbent storage layer, the liquid guide layer and the top layer satisfy the following relationships: the liquid guide layer>the absorbent storage layer>the top layer with respect to a water absorbency due to capillary phenomenon; the liquid guide layer>the absorbent storage layer>the top layer with respect to a retention ratio of a liquid dropped onto the top layer in an amount less than a maximum water absorption amount of the liquid guide layer; and the absorbent storage layer>the liquid guide layer>the top layer with respect to a retention ratio of a liquid dropped onto the top layer in an amount more than the maximum water absorption amount of the liquid guide layer.

The environmental protection shelving combination of the present invention includes sleeves and panels made of corner protection paper for support and plastic connector sets used for coupling the sleeves. Therefore, in accordance with different requirements, the assembly thereof can be altered as desired. Furthermore, since the corner protection paper is formed by pressing Kraft paper and the sand tube paper into a supporting structure, it can provide bearing and pressure capability, so that can replace the conventional wood, plastic or metal framework. Accordingly, not only the costs of material, conveying and assembly can be reduced, the pollution to the environment also can be minimized.

An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of generally congruent irregularly-shaped first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°; a second pair of generally congruent irregularly shaped third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°; a third pair of generally congruent irregularly shaped fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°; wherein the sides of each of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, whereby in use in combination with other flagstones, each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighbouring flagstone.
