  • Patent number: 6610006
    Abstract: An implantable prosthesis for repairing an anatomical defect, such as a soft tissue and muscle wall defect. The prosthesis is configured to reduce the likelihood that an applied force at the repair site, such as due to intraabdominal pressure or tissue shrinkage, can lead to detrimental effects associated with tension at the anchoring locations between the prosthesis and host tissue and/or contraction of the prosthesis. In this regard, the prosthesis may be configured to limit the amount of tension at the anchoring locations caused by the application of a force or pressure to the prosthesis and/or contraction of the prosthesis. Alternatively, the prosthesis may be configured to compensate for contraction of the prosthesis due to tissue shrinkage at the repair site. The prosthesis may be configured to both limit tension at the anchoring locations and compensate for tissue shrinkage.

  • Patent number: 6610087
    Abstract: A modular elongated stent having an overlap region where two modular components fit together, the overlap region being relatively stiff as compared to another more flexible region of the stent when the stent is in an assembled configuration, the stent further comprising a mimic region that has a stiffness essentially equivalent to the stiffness of the overlap region, to provide kink resistance. A stent having such a mimic region or otherwise stiff region and a flexible region may have a transition region between the stiff and flexible regions, such as a bridging material attached to the stent, also to provide kink resistance. A stent may have relatively stiff regions and relatively flexible regions positioned to align the flexible regions with curved regions of a body lumen when deployed within the body lumen.

  • Patent number: 6592619
    Abstract: An actuation system for assisting the operation of the natural heart comprises a framework for interfacing with a natural heart, through the wall of the heart, which includes an internal framework element configured to be positioned within the interior volume of a heart and an external framework element configured to be positioned proximate an exterior surface of the heart. The internal framework is flexibly suspended with respect to the external frame. An actuator system is coupled to the framework and configured to engage an exterior surface of the heart. The actuator system comprises an actuator band extending along a portion of a heart wall exterior surface. The actuator band is selectively movable between an actuated state and a relaxed state and is operable, when in the actuated state, to assume a predetermined shape and thereby indent a portion of the heart wall to effect a reduction in the volume of the heart.

  • Patent number: 6592625
    Abstract: A surgical method of repair and reconstruction of the spinal disc wall, or annulus fibrosus, after surgical incision or pathologic rupture, through the insertion of a collapsible patch through an aperture into the subannular space and causing or allowing the patch to expand into an expanded configuration to bridge the aperture. The technique thereby occludes the aperture from the interior of the vertebral disc and prevents the migration of nucleus pulposus therethrough.

  • Patent number: 6589273
    Abstract: A delivery system and device for re-lining bodily vessels. A stent is attached to a distal end of a tubular lining made of biocompatible material and loaded into a hollow atraumatic tip. A semi-rigid shaft connects the atraumatic tip to a stopper and runs through the center of the tubular lining. The proximal end of the tubular lining is attached to a sliding hub. Optionally, a balloon is positioned near the stent in fluid communication with the shaft. The assembled device is introduced into a bodily vessel following an endarterectomy or atherectomy procedure. The atraumatic tip is delivered to a predetermined location and upon reaching that destination, the stent is released from the tip to expand against the vessel wall. If a balloon is utilized, it is inflated to ensure that the stent is fully deployed within the vessel. The balloon is then deflated arid the tip and shaft are pulled through the expanded stent and tubular lining.

  • Patent number: 6579310
    Abstract: An intravascular stent having struts which overlap, at least partially, when the stent is compressed. The overlapping struts allow the stent to be crimped to a smaller initial delivery diameter than may be achieved with non-overlapping designs for given metal density. The stent has a reduced delivery diameter which allows for the construction of reduced profile stent-delivery systems, which thereby allow for the stenting of smaller vessels than has heretofore been possible.
