Publication number: 20230270463Abstract: An atherectomy device for removing deposits such as plaque from an interior of a vessel including an outer member and a rotatable shaft positioned for rotational movement within the outer member and fixed axially within the outer member. A tip is mounted to the distal region of the rotatable shaft and is positioned distally of the distal end of the outer member to create a gap between the proximal end of the rotatable tip and the distalmost edge of the outer member. The rotatable tip has a longitudinal axis mounted to the rotatable shaft for rotation about its longitudinal axis upon rotation of the shaft, the shaft including a guidewire lumen for receiving a guidewire to enable over the wire insertion of the device.Type: ApplicationFiled: December 16, 2022Publication date: August 31, 2023Applicant: Rex Medical, L.P.Inventors: James F.

Publication number: 20220202441Abstract: A surgical atherectomy apparatus for removing particles such as plaque from an interior of a vessel having a motor housing slidable axially between a proximal position and a distal position. An axially fixed sheath extends from the outer housing and a catheter is connected to the motor housing and is positioned within the sheath. A rotatable shaft is positioned within the lumen of the catheter and is operatively connected to the motor for rotational movement, the rotatable shaft and catheter movable by movement of the motor housing between the proximal and distal positions. The rotatable shaft has an atherectomy bit extending therefrom for dislodgement of particles when rotated by the motor and dislodged particles are aspirated in the lumen of the catheter.Type: ApplicationFiled: February 11, 2022Publication date: June 30, 2022Applicant: Rex Medical, L.P.Inventors: James F.
