    摘要: A stent-graft delivery system and methods for use are provided for use in treating aneurysms occurring in single and bifurcated lumen hollow-body organs or vessels and for treating arterio-venous fistulas. A graft delivery component provides a clinician with complete control over the location of a graft at any time prior to implantation of stents, even when the graft is deployed from its introducer catheter. The graft delivery component includes a plurality of radially expandable fingers that releasably engage the graft, while the stent delivery component includes a small diameter introducer catheter and permits a wide range of conventional stent designs to be used to permanently fix the graft in position.

    摘要: A prosthesis is provided for treatment of aneurysms, occlusive disease of vessels and body organs, and arterio-venous fistulas, comprising an expandable coiled sheet portion having a biocompatible graft affixed thereto. The graft material, preferably a polytetrafluoroethylene ("PTFE") or polyesther material, is affixed to the coiled sheet portion by sintering, suturing, or bonding using a biocompatible adhesive. The coiled sheet portion comprises a lattice formed from a biocompatible material, and may include one or more rows of locking teeth adjacent one edge of the coiled sheet that interengage openings in an opposing edge of the coiled sheet portion to retain the prosthesis at a desired expanded diameter. The prosthesis has a small delivery profile, making it suitable for use in a variety of body vessels. Methods of making and deploying the prosthesis are also provided.

    摘要: A stent comprising a helical mesh coil is provided having a substantially rectangular cross-section and a band width equal to at least one-quarter to one-third of the maximum expanded circumference of the stent. The helical mesh has a multiplicity of openings forming a lattice which preferably provides about 60% open space or more. Alternative embodiments of the helical mesh may include specially designed free ends that preferentially overlap neighboring turns of the coil, to ensure that the free ends of the stent do not project into the body lumen, and integrally formed barbs that induce a ratcheting effect that ensures that the stent resists localized compressive forces. Methods of deploying the helical mesh coil stent also provided.

    摘要: Within a communication system, driving a numerically controlled oscillator with a frequency of a precision frequency oscillator and adjusting the frequency of the numerically controlled oscillator by a calculated number to be equal to that of a frequency signal derived from an external source. The calculated number utilized to adjust the numerically controlled oscillator is then transmitted to each of a number of subunits. Each subunit has another numerically controlled oscillator that is driven by a frequency derived from an internal communication link connecting the subunit to the communication system; and the other numerically controlled oscillator is controlled by the calculated number so that its frequency matches the frequency of the precision oscillator. The frequency of the internal communication link is controlled by the precision oscillator. In a second embodiment, a frequency signal derived from an external source is used to drive a numerically controlled oscillator whose frequency is adjusted by a calculated number to be equal to that of a precision frequency oscillator. The calculated number utilized to adjust the numerically controlled oscillator is then transmitted to each of a number of subunits. Each subunit has another numerically controlled oscillator that is driven by a frequency derived from an internal communication link connecting the subunit to the communication system; and the other numerically controlled oscillator is controlled by the calculated number so that its frequency matches the frequency of the precision oscillator. The internal communication link is frequency locked to the external source.

    摘要: An ankle joint prosthesis comprises an upper part for attachment to an artificial leg and a lower part for attachment to an artificial foot, with the upper and lower parts rotatively coupled and capable of being fixed in a first position for walking, a second position for swimming, or a free-flexing mode for activities such as skiing or rowing. The upper and lower ankle parts have coaxial bores in which a cam part is mounted by means of two bushings. A pin-and-slot arrangement allows locking of the prosthesis in a desired position. Changing positions takes only seconds, and is effected by rotating a spring-loaded "D"-ring on the side of the ankle prosthesis by hand. In a preferred embodiment the ankle joint prosthesis is completely waterproof and precision machined from a lightweight, high-strength plastic.
