  • Publication number: 20040194238
    Abstract: An adjustable toothbrush having a plurality of interchangeable bristle mount settings that facilitate more direct contact with the various teeth geometries. The adjustable toothbrush preferably has at least three selectable surface variations or configurations comprising a flat surface, an inverted/concave surface, and a radial/convex surface. The adjustable toothbrush comprises a brushing surface defined by a plurality of bristles, a bristle mount, at least one adjustment key, hollow brush casing and adjustment mechanism wherein the bristles are secured to the mount and the mount engages the adjustment mechanism. The bristle mount is flexible to accommodate manipulation of its shape by the adjustment mechanism. Depending on the setting, the adjustment mechanism raises the mount to create the radial version, lowers the mount to create the inverted version or leaves the mount stationary for the flat version. The three configurations are selected and engaged by a tactile control.

  • Patent number: 6290731
    Abstract: In accordance with the present invention there is provided a pre-cursor stent for positioning within the infrarenal neck, between an abdominal aortic aneurysm and the renal arteries, of a patient to assist in repairing the abdominal aortic aneurysm. The stent designed to be coupled to a graft for directing blood flow. The graft has a distal end for positioning distal to the aneurysm, and a proximal end for positioning proximal to the aneurysm. The precursor stent includes a substantially cylindrical expandable member having a proximal end, a distal end and an interior. The stent further includes a compressible gasket member located within the interior of the expandable member and attached thereto. The compressible member is substantially impervious to water when in a compressed state. In addition, the stent has a means, within the compressible member, for coupling the graft to the gasket member.

  • Patent number: 6270525
    Abstract: A precursor stent for implantation within the body of a patient is utilized in combination with an aortic graft for repairing an abdominal aortic aneurysm. The stent is designed to receive a pair of grafts placed side by side within the interior of the stent. The stent includes a substantially cylindrical and expandable member having a proximal end, a distal end, a longitudinal axis extending therebetween and an interior. The stent further includes an occlusive member attached to the expandable member. The occlusive member at least partially occludes a passageway or stent lumen which extends through the interior of the expandable member extending between its distal end and proximal end. The occlusive member has an opening extending therethrough designed to receive a guidewire for one of the grafts. Therefore, when the guidewire for the other graft is introduced, after deployment of the stent within a body, it will go through the portion of the interior not covered by the occlusive member.

  • Patent number: 6267783
    Abstract: In accordance with the present invention there is provided a pre-cursor stent for positioning within the infrarenal neck, between an abdominal aortic aneurysm and the renal arteries of a patient to assist in repairing the abdominal aortic aneurysm. The stent is designed to be coupled to a graft for directing blood flow through the aneurysm. The stent is made from a substantially cylindrical self-expanding member having a proximal end, a distal end, a longitudinal axis extending therebetween and an interior. The precursor stent further includes at least two spaced apart longitudinal legs having distal and proximal ends, the proximal ends of the legs attached to the distal end of the member, the legs extending distally from the member, each the leg including a flange adjacent its distal end. Also in accordance with the present invention is an aortic graft, having the above mentioned precursor stent attached thereto when fully deployed.

  • Patent number: 5421349
    Abstract: A vascular catheter guidewire comprises a length of wire having a proximal end, a distal end, and a central portion between the ends having a first diameter range. Typically the range of first diameters is quite narrow and within the dimensions of 0.01 and 0.02 inch. Both the distal end and the proximal end of the guidewire catheter each comprise a tip of greater flexibility than the wire of the central portion of the guidewire. The distal end tip and the proximal end tip are each defined by a length of wire which is integral with the central portion of wire and each has a range of diameters that is less than the range of first diameters. Typically, the diameters of the tip portion wires are on the order of 0.006 to 0.008 inch. The proximal end tip is significantly shorter than the distal end tip. The distal end tip is typically of greater flexibility than the proximal end tip.
