Publication number: 20210169510Abstract: A catheter assembly includes a catheter body with a catheter-body lumen and an embolic protection device. The catheter body is sized for endoluminal advancement of a distal end portion of the catheter assembly from a puncture site at a human dorsalis pedis artery toward one or more larger arteries. The embolic protection device is configured with a collapsed state and a deployed state. The embolic protection device assumes the collapsed state while stowed in the catheter-body lumen at the distal end portion of the catheter assembly. The embolic protection device assumes the deployed state while outside the catheter-body lumen. The deployed state of the embolic protection device is configured with an opening away from the catheter body for capturing emboli dislodged from an arterial lesion while at a distal end of the arterial lesion.Type: ApplicationFiled: November 30, 2017Publication date: June 10, 2021Applicant: C.R. BARD, INC.Inventor: Scott L. Randall

Publication number: 20200261111Abstract: An atherectomy device includes a handpiece having an ultrasonic transducer, and an ultrasonic catheter assembly detachably attached to the handpiece. The ultrasonic catheter assembly includes a sheath having a proximal end, a distal end, and an elongate lumen. A core wire is located in the elongate lumen. The core wire has a distal tip and a distal portion proximal to the distal tip. The distal portion has an abrasive exterior surface portion. The abrasive exterior surface portion defines a plurality of cutting protrusions, wherein each of the plurality of cutting protrusions extends away from the core wire in a distal direction at an acute angle with respect to a longitudinal external surface of the core wire.Type: ApplicationFiled: February 18, 2019Publication date: August 20, 2020Inventor: Scott L.

Patent number: 10342654Abstract: A filter with translating hooks is described. The filter can include strut members having first and second struts connected by a connecting portion. A translating hook is disposed adjacent the connecting portion of the strut members, the hook including a first elongate member attached at one end to the first strut and a second elongate member attached at one end to a second strut, the opposite ends of the elongate members connected together to define a tip. The translating hooks are configured to bend toward a central axis of the filter when the filter is in a collapsed configuration for delivery to a blood vessel and recovery from a blood vessel, and away from the central axis of the filter when the filter is in an expanded configuration within a blood vessel such that the hooks engage a vessel wall.Type: GrantFiled: December 4, 2017Date of Patent: July 9, 2019Assignee: C.R. BARD, INC.Inventors: Andrzej J. Chanduszko, Scott L. Randall, William R. Bratt
