Publication number: 20230037603Abstract: An atherectomy device (100) for removing occlusive material from the vasculature of a subject includes a sheath (116) and a drive shaft (216) disposed within the sheath. The drive shaft (216) couples to a cutting element (118). The drive shaft (216) is rotatable relative to the sheath (116) to rotate the cutting element (118). The drive shaft (216) and the sheath (116) define therebetween a material removal passageway (218) for receiving the occlusive material. The drive shaft (216) includes a coil (504) having an inner lumen (512). A jacket (516) is disposed outwardly of the coil (504), and the jacket (516) inhibits the occlusive material in the material removal passageway (218) from passing through the coil and entering the inner lumen (512).Type: ApplicationFiled: December 10, 2020Publication date: February 9, 2023Inventors: August Christopher POMBO, Paul Q ESCUDERO, Douglas ROWE

Publication number: 20220296270Abstract: An atherectomy device including a handle configured to be manipulated by a user. The device further includes a catheter comprising an outer sheath and a drive shaft carried within and rotatable relative to the outer sheath. A cutter assembly is coupled to and extends distally relative to the outer sheath. The cutter assembly includes a housing coupled to and extending distally from the outer sheath. A proximal cutting element is rotatably carried by the housing, and the proximal cutting element is coupled to and extends distally from the drive shaft. The proximal cutting element includes a cutting stem having at least one cutting feature and at least one cutting blade coupled to the cutting stem. A distal cutting element is carried by the cutting stem and is rotatable with the proximal cutting element relative to the housing. The distal cutting element includes at least one cutting blade.Type: ApplicationFiled: June 11, 2020Publication date: September 22, 2022Inventors: Douglas ROWE, Paul Q ESCUDERO, August Christopher POMBO

Publication number: 20210386451Abstract: An atherectomy device includes a catheter, and the catheter includes an outer sheath. The outer sheath includes a proximal portion coupled to and extending distally relative to a handle, and the proximal portion defines a longitudinal axis of the catheter. The outer sheath also includes a distal portion coupled to and extending distally relative to the proximal portion, and the distal portion normally has a curved configuration and is offset from the longitudinal axis. The catheter further includes a drive shaft carried within and rotatable relative to the outer sheath. A cutter assembly is coupled to and extends distally relative to the distal portion of the outer sheath. A cutter is coupled to the drive shaft and rotates about a cutter rotation axis upon rotation of the drive shaft relative to the outer sheath. The cutter rotation axis is normally disposed at an acute angle relative to the longitudinal axis.Type: ApplicationFiled: October 31, 2019Publication date: December 16, 2021Inventors: Paul Q ESCUDERO, Douglas ROWE, August Christopher POMBO

Patent number: 9492347Abstract: Devices and methods for attaching a belt cartridge to a belt drive platform. A clip 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: GrantFiled: June 3, 2014Date of Patent: November 15, 2016Assignee: ZOLL Circulation, Inc.Inventors: Reynaldo J. Quintana, Paul Q. Escudero, Charles E. Swinehart

Patent number: 9078800Abstract: 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. The means for tightening a belt then repetitively tightens the belt, thereby accomplishing chest compressions.Type: GrantFiled: March 4, 2014Date of Patent: July 14, 2015Assignee: ZOLL Circulation, Inc.Inventors: Paul Q. Escudero, Gregory W. Hall
