Publication number: 20150359445Abstract: A pressure sensing device is provided that can monitor and measure pressure at two points in a vessel or artery without moving the outer sheath or catheter of the device. The outer sheath or catheter includes two spaced apart openings that may be positioned in a vessel or artery on opposing sides of an occlusion. The device also includes an inner elongated tube with at least one opening. The inner elongated tube is slidable with respect to the outer sheath or catheter thereby permitting the opening of the elongated tube to be moved into selective registration with one of the openings of the outer sheath. A pressure measurement may be taken through one of the openings in the outer sheath by aligning the opening of the elongated tube with said opening and, then, a second pressure reading may be taken by sliding the elongated tube within the outer sheath so that the opening of the elongated tube is in registry with the other opening of the tubular sheath.Type: ApplicationFiled: August 24, 2015Publication date: December 17, 2015Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: TIMOTHY G.J. EHR, BRUCE H. ASMUS

Patent number: 8986367Abstract: A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.Type: GrantFiled: January 23, 2014Date of Patent: March 24, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Graig L.
