Filed:

Oct 17, 2018

Appl. No.:

16/163543

Inventors:

- Eindhoven, NL
Douglas E. ROWE - Menlo Park CA, US
Paul ESCUDERO - Menlo Park CA, US
August Christopher POMBO - Sacramento CA, US

International Classification:

A61B 17/3207
A61B 17/00
A61B 17/22

Abstract:

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.

International Classification:

A61B 17/3207
A61B 8/00
A61B 8/12

Abstract:

The present invention relates to apparatuses for cutting and removing occlusive material with imaging capabilities. According to certain aspects, the apparatus includes a catheter body, a rotatable shaft, and an imaging element. The catheter body defines a lumen and includes a distal housing that defines an opening. The rotatable shaft is disposed within the lumen of the catheter body. The rotatable shaft includes a conveying component and a cutting element that is at least partially surrounded by the distal housing. The imaging element is located on the distal housing of the catheter body.

Inventors:

- Menlo Park CA, US
Paul Quentin ESCUDERO - Redwood City CA, US
Douglas E. ROWE - San Jose CA, US
August Christopher POMBO - Sacramento CA, US

International Classification:

A61B 17/3207
A61B 17/32

Abstract:

Described here are devices and components for use in performing an atherectomy. Generally, the atherectomy devices may have a handle, a cutter assembly, and a catheter or catheter assembly therebetween. The cutter assembly may include a housing and a cutter comprising a proximal cutter and a distal cutter, each of which may be rotated relative to the atherectomy device to cut occlusive material.
