Patents by Inventor Andrew W. Conder

Andrew W. Conder 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: 9844653
    Abstract: An occlusion device includes first and second crossing frame elements each of annular ring-shape, as well as first and second annular support elements connected to respective extremities of the crossing frame elements. The frame and support elements are provided with covers made of a substantially impervious material. The occluder may include a covering sleeve of stretchable material. The occluder substantially stops or reduces the flow of blood therethrough, creating blood statis and subsequent occlusion by clot formation within the occluder. The structure of the frame elements ensures good edge sealing and enhanced fixation of the occluder in a vessel as blood pressure impinges upon the covers of the occluder.

  • Patent number: 9307997
    Abstract: A vascular occluder includes first and second baffle members which are formed of an expansion device such as a stent across which extends an impermeable membrane. The baffle members are held at a given separation by spacer elements. The separation creates a chamber between the baffle members in which the blood is able to stagnate, thereby creating a second occlusion barrier. One of the baffle members may have an aperture within its membrane for receiving a delivery catheter for delivery of thrombogenic agent into the chamber. The occluder has a given length, thereby making it suitable for implantation in difficult vessel sections and is also able to avoid problems of recanalization of the vessel which can occur with prior art occluders.

  • Patent number: 8702746
    Abstract: The present invention provides an improved occluding device and an improved method of occluding fluid through a body vessel. The occluding device comprises an inner coil. At least one outer coil is disposed about a portion of the inner coil. The outer coil has a pre-curled tension to facilitate the outer coil to be curled within the lumen of the body vessel when deployed.

  • Patent number: 8663308
    Abstract: The medical devices, such as stent grafts, described herein preferably include a tubular remodelable graft material attached to a support frame formed at least in part from a metallic bioabsorbable material. The remodelable graft material preferably includes an extracellular matrix material such as small intestinal submucosa (SIS). The support frame attached to the graft is preferably a bioabsorbable magnesium alloy. The devices may be implanted within a peripheral vascular body vessel from a percutaneous delivery catheter.

  • Patent number: 8057495
    Abstract: A system and method for occluding an aneurysm formed in a dilatation area of a body vessel are disclosed. The system comprises a wire guide, a core wire, and an occlusion device. The wire guide comprises a proximal end and a distal end, and has a passageway that extends from the proximal end to the distal end. The core wire comprises a distal end and a proximal end, and is disposed through the passageway so that the proximal end of the core wire proximally extends beyond the proximal end of the wire guide. The occlusion device comprises a distal end and a proximal end, and has a deployed state and an undeployed state. The occlusion device has a pre-set spiraled coil shape when in the deployed state in the vessel. The occlusion device is disposed distally from the core wire in the passageway.
