  • Patent number: 7166125
    Abstract: An intraluminal grafting system having a delivery catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member and including a graft disposed within the capsule. The graft is comprised of a tubular body configured to be secured to a blood vessel by a self expanding attachment system. The attachment system comprises a generally sinusoidal wire frame having apices which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices and the base apices are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members that are oriented in a responsive relationship to the radially outward bias of the attachment system.

  • Patent number: 7044973
    Abstract: A shoulder prosthesis of the present invention includes a modular humeral prosthesis component employing a collarless design. A body portion of the prosthesis is provided without a collar, and it may be implanted into a prepared proximal end of a humerus such that the body sits recessed below the level of the cut proximal surface of the humerus. A head portion is provided in which a support surface of the head functions as collar by direct apposition of it to the cut proximal humerus. The modular connection is thus recessed below the proximal bone surface. By providing a modular connection which is recessed below the bone surface, the benefits of modularity may be retained, while joint overstuffing may be reduced or eliminated, and a substantially full range of motion may be achieved.

  • Patent number: 6994723
    Abstract: Medical devices are made from a self-stiffening composite including a base material, a polymerizer and a corresponding activator for the polymerizer. The medical devices have an initial configuration in which the polymerizer and activator are separated from each other and an activated configuration in which the polymerizer and activator are brought into contact with each other. Polymerization is triggered when the polymerizer and activator are contacted together, forming a polymer that stiffens the medical device. The medical device may thus be flexible in the initial configuration so it can be easily advanced through tortuous passageways during delivery to a body lumen and further have sufficient radial strength in the activated configuration to hold open the body lumen after implantation.

  • Patent number: RE39335
    Abstract: A tubular graft/stent includes a tubular sheath (10) having at intervals along its length a plurality of ring-like rigid members (11), which are attached to the sheath around their respective circumferences and are made of a shape memory material, so that when the members (11) change shape the sheath (10) adopts a new cross section in conformity with them along its whole length. The members may be discontinuous to allow the adoption of a contracted shape in the martensitic phase and an expanded shape in the austenitic phase. A graft may also have a side tube (14) which can be inverted so as to be housed within the sheath.
