  • Patent number: 7217227
    Abstract: An upper body exercise apparatus for assisting an exerciser in performing chin-ups and dips. The apparatus includes at least two securely yet releasably attached elastic stretch components connected to a substantially inelastic flexible component that functions as a suspended sling. The method of exercise is to engage part of the body within the sling to allow the elastic resistance to counteract a portion of the exercisers body weight and thus enable the exerciser to perform these effective body weight exercises with less effort than that required with the exerciser's full body weight.

  • Patent number: 6520983
    Abstract: The present invention relates to a system for delivering a medical prosthesis into a body lumen. A preferred embodiment of the invention utilizes a catheter having a stent mounted at the distal end that is released into the body lumen by movement of an outer sheath covering the stent in the proximal direction. The stent expands to conform to the inner wall of the lumen and the catheter is withdrawn.

  • Patent number: 6488689
    Abstract: Methods and apparatus for closing a left atrial appendage are described. The methods rely on introducing a closure tool from a location beneath the rib cage, over an epicardial surface, and to the exterior of the left atrial appendage. The closure device may then be used to close the left atrial appendage, preferably at its base, by any one of a variety of techniques. A specific technique using graspers and a closing loop is illustrated.

  • Patent number: 6468285
    Abstract: Paired vascular clamps simplify laparoscopic vascular reconstruction surgery by providing an instrument for bringing vessel ends together to a reasonable working distance under a controlled fashion. A first clamp, with a pivoted connecting arm, and a second clamp with a lock/release device for attaching the second clamp to the connecting arm, can be inserted through an trocar or other port into a surgical field and then positioned on with the first clam and the second clamp in side-by-side and substantially parallel relationship, so that said first clamp and said second clamp can hold and position one or more vessels or elongated tissues. A laparoscopic approximator-everter has extendable blades for gripping blood vessel edges or other tissue to be anamosted, and an extendable sheath that can be advanced to surround the blades.

  • Patent number: 6443979
    Abstract: An expandable delivery sheath is provided for intravascular introduction into a patient's vasculature by means of a guiding catheter. An interventional device, such as a stent delivery catheter, is subsequently advanced within the expandable sheath to a point where the stent traverses an arterial lesion. The sheath forms a protective barrier between the lesion and the stent and it delivery catheter, thereby preventing the creation of emboli which might otherwise be produced by abrasion of the stent against the plaque of the arterial lesion. Prior to expansion of the stent, the expandable sheath is retracted from the area of treatment.

  • Patent number: 6440162
    Abstract: The invention is directed to a stent that is relatively flexible along its longitudinal axis but can be crimped or reduced to a very low profile while maintaining the ability to expand radially outwardly to any number of diameters to support a body lumen such as a coronary artery. The stent includes a plurality of cylindrical rings connected to each other by links. The cylindrical rings have curved portions that are attached by arms having slits that, when expanded, form apertures or holes to permit the stent to be reduced to a very low profile for delivery purposes, yet be able to expand the stent to various diameters and to provide sufficient vessel wall coverage when implanted.

  • Patent number: 6428554
    Abstract: A dual action tongue scraper provides either a hard scrape or a soft scrape of the tongue, as desired. A hard scraping surface and a soft scraping surface are formed along at least one of the edges of a strip of flexible material. A user bends the strip of flexible material such that generally only one of the hard scraping surface and the soft scraping surface contacts the user's tongue at a given time during scraping.

  • Patent number: 6425909
    Abstract: An intravascular filter having a filament which expands a filter element. The filament is a coil which is stretched to reduce the diameter of the coil for introduction. The filter element is preferably biased toward the closed position and is opened by the coil when tension is released on the coil. The filament slides along the internal surface of the filter element so that the filter element may assume intermediate positions.
