  • Patent number: 9968337
    Abstract: Biopsy devices and methods are provided for collecting a sufficiently-sized tissue sample from a region at a known distance by boring into the sample region using simultaneous axial and rotational movement and providing a reduced risk of: over-passing or under-passing the sample sought, injury and trauma to the surrounding tissue area, having to stick the patient more than once, sample contamination, and the user's exposure to sharps.
    Type: Grant
    Filed: December 14, 2011
    Date of Patent: May 15, 2018

  • Patent number: 9089445
    Abstract: An endoluminal prosthesis is described and comprises a stent (40), At least one barb (42) secured to the stent, and a degradable barb guard (52) covering at least a portion of the barb and protecting the distal tip when the stent is in a compressed configuration. The barb guard (52) comprises a degradable structure that degrades to expose the distal tip of the barb when the stent is placed in a vessel. An endoluminal prosthesis deployment system comprising a sheath having a lumen and a prostesis within the sheath lumen is also described.

  • Patent number: 8696739
    Abstract: An endoluminal prosthesis includes a support structure including a curvilinear portion having a first strut and a second strut that meet at an apex. Disposed on the support structure is an anchor with an anchor body and one or more barbs extending outwardly from the anchor body. The anchor body can fit at least partially about, and can conform to the first strut, second strut, and the apex. A curved portion of the anchor and the curvilinear portion of the support structure can be co-formed, resulting in a secure interference fit so that welding, soldering, or other joining mechanisms can be avoided. Cutouts can be formed along the curved portion of the anchor to relieve stress or strain during the co-forming process.
