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

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.

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
