Abstract: A fastening system includes a grommet having a grommet shank and two grommet cap ends secured to opposing ends of the grommet shank; a planar border having a base and integrally formed substantially parallel planar flexible peripheral first and second legs of substantially like length, the first leg having a first leg distal end with a first aperture and the second leg having a second leg distal end with a second aperture and an integral and peripheral first spike having a first spike pointed end, each of the first and second apertures being proportioned for slidable receipt of the grommet when the first and second apertures are aligned with each other; and an elongate securement leg integrally dependant from the base in a direction of the distal ends of the flexible legs, and including a securement leg distal end having a receiving surface for receiving first spike pointed end.

Abstract: 1. A fastening system includes a straight pin having a cap end, a shank and a pointed end; a planar border having a base and two integrally formed substantially parallel planar flexible peripheral legs of like length, distal ends of each of the legs having apertures proportioned for slidable receipt of the shank of the straight pin; and an elongate securement leg integrally dependant from the base in a direction of the distal ends of the flexible legs, a distal end of the securement leg including a female surface press-fittably complemental about the pointed end of the straight pin. The pin may be inserted through the apertures when they are aligned with each other, and then held by the female surface to enable securement of a planar peripheral legs to each other.

Abstract: A tire valve incorporates a visual gauge, an element for setting different air pressures. The valve cannot overinflate, as the valve locks at a maximum pressure. Further, an indicator actuates when underinflated, and the valve is designed to keep pressure for an indefinite period.

Abstract: The curving tip catheter is adapted to be inserted into and through the lumen of a blood vessel in a network of branching blood vessels in a body and is manipulatable therethrough to a desired blood vessel branch within the network of branching blood vessels. The catheter includes an elongate tubular body having a distal end and a proximal end, and a flexible tubular tip portion located at the distal end of the elongate tubular body. The catheter further includes at least first and second elongate passageways within the tubular body and at least first and second elongate lumens within the flexible tip portion and which mate with the first and second respective elongate passageways of the tubular body. The tubular body includes braided wire embedded into the wall of the tubular body, or an inner tubular lining within the tubular body situated between the tubular body and the first and second elongate passageways, both of which provide torsional stiffness to the tubular body.

Abstract: A vessel dilation device is provided for use within the vascular system, such device including a braided cylinder that has an adjustable axial length and that is structured such that reduction of its adjustable axial length increases its radial size in order to effect a desired extent of dilation.
