  • Patent number: 10772719
    Abstract: A method of making a contoured internal limb including providing a flattened tubular segment of graft material, and a prosthesis including the contoured internal limb. The tubular segment includes a left lateral edge, a right lateral edge, a first length extending from the left lateral edge to the right lateral edge, and a second length extending from a proximal end to a distal end of the tubular segment. The method also includes contouring a proximal portion, a middle portion, and a distal portion of the contoured internal limb from the tubular segment. The method also includes closing a right lateral edge of the proximal portion and a right lateral edge of a first section of the middle portion. The method further includes removing the proximal, middle and distal portions of the contoured internal limb from the tubular segment and maintaining a second section of the middle portion as circumferentially continuous.

  • Publication number: 20170056151
    Abstract: The present embodiments describe an endograft having one or more apertures, and methods for constructing the same. In one example, an endograft comprises a proximal region having a proximal opening, and a distal region having first and second apertures separated by a partition. A body portion having a lumen is disposed between the proximal region and distal region, and has a central longitudinal axis. At least one of the first and second apertures is oriented oblique to the central longitudinal axis.

  • Patent number: 9282948
    Abstract: Total core biopsy devices and methods of use are provided for taking a total core biopsy sample and a means for using the devices that provide for an adequate sample size and quality while being light-weight, easy to use, small, inexpensive, and permitting one-handed operation and beveled edges to reduce trauma to the surrounding tissue and organs from which a total core biopsy sample may be taken.

  • Publication number: 20120245486
    Abstract: Among other things, there is disclosed embodiments of biopsy needles having improved radiological visualization properties. Exemplary needles include an outer cannula and a stylet slidable within the cannula. At least a portion of the stylet is radiologically contrasting to at least a part of the cannula. When the stylet is extended from the cannula within the patient, the clinician can observe radiologically where the extended portion of the stylet is, because of the radiological contrast between the stylet and cannula. The clinician can compare that contrasting area to the tissue of interest, to assure that the needle is properly placed.
