Publication number: 20220387071Abstract: Telescoping, self-driving, and laterally-pushing atherectomy devices are provided, each having a flexible sheath, a cutter with helical flutes, and a drive assembly. The drive assembly can have a flexible driveshaft rotatably translational with the lumen of the flexible sheath, a positive displacement pump to transport cut tissue, and a flexible drive shaft that can be longer than the flexible sheath for a reversible telescoping of the drive assembly from the lumen of the flexible sheath. The positive displacement pump can be a screw pump having a drive screw portion exposed for contact with a vascular lumen for a self-driving of the device through the vascular lumen. A reversibly-expandable, lateral pushing member can be included at the distal end of the flexible sheath for a lateral pushing of the cutter. Improved cutting heads, and methods of making them, are provided for cutting a combination of soft and hard plaque.Type: ApplicationFiled: June 7, 2022Publication date: December 8, 2022Inventors: John To, Paul Escudero

Publication number: 20220192698Abstract: Telescoping, self-driving, and laterally-pushing atherectomy devices are provided, each having a flexible sheath, a cutter with helical flutes, and a drive assembly. The drive assembly can have a flexible driveshaft that is rotatably translational with the lumen of the flexible sheath, a positive displacement pump that begins pumping at the distal end of the drive shaft adjacent to the helical flutes at the proximal end of the cutter, and the flexible drive shaft can be longer than the flexible sheath to enable a reversible telescoping of the drive assembly from the lumen of the flexible sheath. The positive displacement pump can be a screw pump having a drive screw portion extending beyond the flexible sheath, exposed for contact with a vascular lumen for the self-driving. And, the devices can have a reversibly-expandable, lateral pushing member at the distal end of the flexible sheath for the lateral pushing.Type: ApplicationFiled: March 11, 2022Publication date: June 23, 2022Inventors: John To, Paul Escudero

Patent number: 11317940Abstract: The invention generally relates to intraluminal procedures, and, more particularly, to a contra-rotating cutting assembly for use with an atherectomy device to remove occlusive material from an occluded lumen, such as a blood vessel or other body lumen. The contra-rotating cutting assembly includes a rotatable housing having a distal end, an opposing proximal end and a lumen extending between the distal and proximal ends. The housing is configured to rotate about a longitudinal axis in a first direction. The cutting assembly further includes a rotatable cutter head positioned within at least a portion of the lumen of the housing and in coaxial alignment with the housing. The cutter head is configured to rotate about the longitudinal axis in a second direction opposite the first direction.Type: GrantFiled: October 17, 2018Date of Patent: May 3, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Torrey P. Smith, Douglas E. Rowe, Paul Escudero, August Christopher Pombo

Publication number: 20050080362Abstract: Devices and methods for attaching a belt cartridge to a belt drive platform. A spline attached to the belt is inserted into a slot in the drive spool of the belt drive platform. The cover plate of the belt cartridge fits into a channel beam in the housing of the belt drive platform, thereby securing the cartridge to the housing. Belt guards, for protecting the cartridge, belt drive platform, patient and rescuer, are rotatably attached to the cover plate and are secured around spindles disposed on the sides of the housing.Type: ApplicationFiled: October 14, 2003Publication date: April 14, 2005Inventors: Reynaldo Quintana, Paul Escudero, Charles Swinehart

Publication number: 20050080364Abstract: A lightweight electro-mechanical chest compression device. The device is provided with a motor, a brake, a drive spool, a control system, and a metal channel beam to brace the device and guide a compression belt. The belt is provided in a belt cartridge that attaches to the channel beam. In use, the belt is secured around the patient and to the drive spool. The motor tightens the belt by turning the drive spool. The electro-mechanical chest compression device weighs less than 30 pounds when fully assembled with its power source.Type: ApplicationFiled: October 14, 2003Publication date: April 14, 2005Inventors: James Jensen, Paul Escudero, Reynaldo Quintana, Charles Swinehart

Publication number: 20050080361Abstract: A compression belt cartridge for use with chest compression devices. The compression belt cartridge has a double-oar shaped belt and a cover plate through which the belt is threaded. The cover plate is provided with hooks and snap latches that fit into a belt drive platform. The cover plate is sized and dimensioned to fit within only selected platforms. The belt attaches to the means for tightening the belt via a spline attached to the belt.
