Diana Sanchez has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8202310
    Abstract: An abdominal aortic aneurysm repair device having an access port may be utilized to percutaneously access the aneurismal sac without disturbing the repair. The access port has a self-sealing member for maintaining the port in the normally closed position. The insertion of a percutaneous device into the port opens the port.
    Type: Grant

  • Publication number: 20070156227
    Abstract: A prosthetic stent graft for the treatment of AAA includes a plurality of graft legs, each secured in a deployed position by a sealing gasket within a stent segment of the sealing gasket and to one side of a framing bracket. The framing bracket traverses the diameter of the stent segment and extends axially away, dividing the first stent segment into two portions, each portion for receiving a graft leg of the stent graft. The sealing gasket can include a stabilizer having a second generally cylindrical stent segment, and an extension bracket traversing the diameter of the second stent segment and extending away from the second stent segment. The extension bracket and the first bracket are connected with one another at a mutual generally central position.

  • Publication number: 20070112410
    Abstract: A stent graft having graft material attached to a stent structure while providing a low profile to the stent graft in its crimped state. The graft material may be attached to an internal surface, an external surface, or both the internal surface and the external surface of the stent. The graft material may cover all or part of such surfaces. The stent graft is expandable upon delivery to the intended treatment site. The expandable nature of the stent graft may be accomplished by self-expanding materials, or through other methods, such as balloon expansion, as generally practiced in the art. The stent graft material is comprised of durable biocompatible materials as generally practiced in the art. The stent graft in its crimped state comprises a low profile fluid flow conduit that is preferably percutaneously delivered, but that may be surgically emplaced to the intended treatment site.

  • Publication number: 20060025846
    Abstract: An endoprosthesis for repairing and treating abdominal aortic aneurysms. The endoprosthesis features an anchoring and sealing component and low profile bifurcated legs. A biocompatible graft material is secured to at least the bifurcated legs in order to provide two endoleg fluid flow lumens or conduits. The bifurcated legs have staggered stent elements that nest to contribute to the low profile nature of the device and additional longitudinal struts between pair of the staggered stent elements to increase the longitudinal stiffness of the bifurcated legs while maintaining the patency of the lumen created thereby.

  • Publication number: 20060025844
    Abstract: A reduced deployment force delivery apparatus having an outer sheath with two layers that move relative to one another so as to reduce the deployment force necessary for deploying a stent, stent graft or other intraluminal device.

  • Patent number: 6636758
    Abstract: This is a medical device, specifically used in surgery. It is a wire having distal radio-opaque markers and may be used, for instance, in endovascular procedures as a marker wire for estimating or referencing the structural attributes of internal physical features. In addition, the inventive marker wire may be used as a guide wire for a catheter used in endovascular procedures.

  • Publication number: 20020177870
    Abstract: This invention is a surgical device. In particular, it is a low profile, single lumen catheter preferably having a movable seal or seat that allows the balloon to be inflated by sealing against the movable guidewire or against itself. An additional variation of the invention includes a non-removable guidewire situated in the catheter body in such a way to provide or add stiffness to the otherwise flexible distal section of the catheter during a procedure. An enhanced strain relief transition joint between significantly stiffer proximal section and the more flexible distal section is provided. Finally, methods of using the inventive balloon catheter are also shown.
