  • Patent number: 9668718
    Abstract: A tissue removal apparatus and needle assembly for extracting a tissue portion from tissue or the like, the needle assembly comprising an inner tube having an interior cavity, an outer cannula having a proximal end, a distal end and an interior cavity, the interior cavity of the outer cannula having an interior diameter to slidably receive the inner tube and a collapsible section operably engaged with the inner tube and the outer cannula whereby a forward movement of a portion of the inner tube within the interior cavity of the outer cannula changes the collapsible section from a neutral position to a collapsed position to engage the tissue portion. In some embodiments, the outer cannula further comprises an aperture configured to allow a tissue portion from within the needle assembly to pass through or otherwise be expelled outside of the needle assembly.

  • Patent number: 8218795
    Abstract: A geometrically shaped acoustic polymer ribbon with shape memory, high conductivity, high toughness. A method of manufacturing the ribbon comprises: forming a sized, elongated, coated or coatable polymeric substrate film between a pair of opposed, geometrically shaped dies, pinching the dies about the polymeric substrate film to form an assembly, heating the dies and the pinched die and polymeric film assembly to a temperature of at about 300 degrees F. for a period of about 15 minutes to set the elongated film into a predetermined geometric pattern, cooling the assembly, removing the film from the dies; and if not already coated, coating the geometrically formed, set, elongated film with a conductive coating.

  • Patent number: 5496330
    Abstract: A surgical extractor for removing calculi, such as kidney stones and gall stones, from the body. The extractor includes a handle at an proximal end of the extractor with a slider for operation by a physician. At the distal end the extractor includes a plurality of pairs of wires with portions of each pair being formed along the turn of a helix. When a retaining sheath is retracted, the wires, formed of a shape memory material such as stainless steel, expand such that each pair of wires closely assumes a path along a helical turn with individual wires remaining closely adjacent. This use of plural wires for each strand multiples the number of contacts with entrapped calculi and can be provided without any deleterious effect on the reliability or size of the extractor.

  • Patent number: 4830023
    Abstract: A medical guidewire has an elongated body that has a degree of flexibility and a distal tip region of relatively greater flexibility. The guidewire consists of a core having a body of first diameter, a distal portion of a relatively smaller diameter, and a generally flat distal end. The end is disposed in the tip region and is spaced proximally from a round tip element that defines the distal end of the guidewire. A first coil is joined to the core body and extends along the core to a termination point in the distal tip region, proximal of the end of the core. A relatively more flexible second coil is joined at its proximal end to the first coil and joined at its distal end to the round tip element. A safety wire is secured to the core and has a generally flat distal end within the second coil, joined to the round tip. A transition wire is secured to the core and has a generally flat distal end that terminates within the second coil intermediate of the distal ends of the core and safety wire.
