Publication number: 20220273337Abstract: Described herein are atherectomy catheters, systems and methods that include longitudinally displaceable drive shafts that drive actuation of one or more cutters at the distal end of the catheter. The catheters described herein may include one or more imaging sensors for imaging before, during or after cutting tissue. In some variations the imaging sensor may be rotated around the perimeter of the catheter independently of the rotation of the cutter. Also describe herein are imaging catheters that may be used without cutters.Type: ApplicationFiled: May 20, 2022Publication date: September 1, 2022Inventors: Himanshu N. PATEL, John B. SIMPSON, Charles W. McNALL, Maegan K. SPENCER, Michael ZUNG, Priyanshu GUPTA, Nicholas J. SPINELLI, Myra L. FABRO, Eduardo SUCGANG, Theodore W. KETAI

Publication number: 20210330345Abstract: A catheter device for crossing occlusions includes an elongate catheter shaft, a rotatable tip configured to rotate relative to the elongate catheter shaft, a drive shaft, and an OCT imaging sensor. The rotatable tip includes a housing coupled with the elongate catheter shaft and cutting wedges extendable from the housing. The drive shaft has a central lumen extending therethrough and extends within the elongate catheter shaft. The drive shaft is coupled with the wedges and is configured to rotate the rotatable tip. The OCT sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. The elongate catheter shaft is configured to move axially over the drive shaft to extend and retract the wedges from the housing while maintaining a fixed position of the imaging sensor relative to the cutting wedges.Type: ApplicationFiled: March 22, 2021Publication date: October 28, 2021Inventors: Richard R. NEWHAUSER, Theodore W. KETAI, Peter H. SMITH, Myra L. FABRO

Patent number: 10335173Abstract: A stylet for re-entry into a vessel includes an elongate body including a proximal portion, a middle curved portion, a pointed distal end, and a longitudinal axis extending through the proximal portion, the middle curved portion, and the pointed distal end. The proximal portion and the middle curved portion have substantially circular cross-sections. The middle curved portion has a pre-shaped curve along the longitudinal axis configured to match a curve of an occlusion-crossing device. The pointed distal end has an s-curve along the longitudinal axis and a flattened portion along the longitudinal axis, the flattened portion having a substantially oblong cross-section.Type: GrantFiled: March 15, 2013Date of Patent: July 2, 2019Assignee: Avinger, Inc.Inventors: John B. Simpson, Myra L. Fabro, Eduardo Sucgang, Priyanshu Gupta, Theodore W. Ketai
