Abstract
An atherectomy device having a housing at the distal end of a catheter adapted for insertion into the vascular system. The housing has a cutout in one side, and a cutter that is mounted in the housing for both axial and rotary movement with respect to the cutout. At least a portion of the housing is formed of a material which permits bending of the housing as it follows the contours of the vessel. The housing is also adapted to retain the severed atheroma materials.

In an atherectomy device for use in a vessel, a flexible tubular member having proximal and distal ends and having at least one lumen extending therethrough, a housing secured to the distal end of the tubular member, the housing having a cutout in one side thereof extending longitudinally of the housing and facing outwardly in a direction which is generally perpendicular to the longitudinal axis of the housing, a collection chamber formed in the housing for retaining severed atheroma materials within the atherectomy device, a rotary cutter mounted in the housing for movement longitudinally of the housing through the cutout, at least a portion of the housing being flexible so as to permit bending of the housing between its distal and proximal extremities whereby the housing has the capability of following contours in a vessel in which the atherectomy device is to be utilized and, inflatable balloon means carried by the housing and mounted exterior of the housing on the side opposite the cutout so that when the balloon means is inflated the cutout will be moved towards the sidewall of the vessel.
In the atherectomy device for use in a vascular vessel, a flexible tubular member having proximal and distal ends and having at least one lumen running therethrough, the flexible tubular member being adapted for insertion into the vascular vessel, a housing carried by the distal extremity of the tubular member and having a cutout on one side thereof, the cutout extending longitudinally of the housing and facing outwardly in a direction that is generally perpendicular to the longitudinal axis of the housing, the housing having a collection chamber spaced distally of the cutout for retaining severed atheroma materials within the housing, a cutter rotatably mounted within the housing for movement longitudinally of the housing past the cutout, the cutter having an annular cutting edge, the portion of the housing containing the collection chamber being flexible so as to permit bending to allow the housing to follow contours in a vessel in which the atherectomy device is to be utilized.
