Abstract
An atherectomy system includes an atherectomy burr and a drive mechanism that is adapted to rotatably actuate the atherectomy burr and to accommodate a guidewire extending therethrough. A controller is adapted to regulate operation of the drive mechanism. A guidewire extends through the drive mechanism and an electromagnetic guidewire clamp is adapted to releasably secure the guidewire relative to the drive mechanism.
Claims20
An atherectomy system, comprising:
- an atherectomy burr;
- a drive mechanism adapted to rotatably actuate the atherectomy burr, the drive mechanism adapted to accommodate a guidewire extending therethrough;
- a guidewire extending through the drive mechanism;
- and
- an electromagnetic guidewire clamp adapted to releasably secure the guidewire relative to the drive mechanism, the electromagnetic guidewire clamp comprising:
- an electromagnet secured within a primary clamp housing;
- a clamping element disposed relative to the electromagnet such that the clamping element can move in a first direction relative to the electromagnet when the electromagnet is actuated and can move in a second direction relative to the electromagnet when the electromagnet is not actuated;
- wherein actuating the electromagnet causes the clamping element to move relative to the electromagnet, thereby clamping the guidewire.

An atherectomy system, comprising:
- a handle including a handle housing;
- an atherectomy burr;
- a drive motor disposed within the handle housing and adapted to rotatably actuate the atherectomy burr via a drive cable extending from the drive motor to the atherectomy burr, the drive cable adapted to accommodate a guidewire extending through the drive cable;
- and
- an electromagnetic guidewire clamp adapted to releasably secure the guidewire relative to the drive cable, the electromagnetic guidewire clamp including:
- an electromagnet;
- and
- a clamping element slidingly disposed relative to the electromagnetic such that the clamping element can move towards the electromagnet when the electromagnet is actuated and clamp the guidewire in place.

An atherectomy system, comprising:
- an atherectomy burr;
- a drive mechanism adapted to rotatably actuate the atherectomy burr, the drive mechanism adapted to accommodate a guidewire extending therethrough;
- a guidewire extending through the drive mechanism;
- and
- an electrically actuated guidewire clamp adapted to releasably secure the guidewire relative to the drive mechanism, the electrically actuated guidewire clamp comprising an electromagnet and a clamping element slidingly disposed relative to the electromagnet such that the clamping element can move towards the electromagnet when the electromagnet is actuated in order to clamp the guidewire in place.
