Steerable device having a corewire within a tube and combination with a functional medical component
First Claim
1. A biocompatible integrated guiding device comprising a tube with an internal lumen, a corewire within the lumen of the tube, and a torque coupler that can couple the rotational motion of the tube with the rotational motion of the corewire wherein the corewire can be moved longitudinally at least some amount within the lumen of the tube.

Abstract
An integrated guiding device has a tube and a corewire within the tube and a torque coupler. The torque coupler can couple the rotational motion of the tube with the rotational motion of the corewire. The wire can be moved longitudinally at least some amount relative to the tube. The device can further comprise a functional medical structure, such as an embolism protection structure. The device can be used in medical procedures, such as less invasive procedures within the cardiovascular system. Improved fiber based embolism protection devices comprise fiber bundles that are twisted prior to delivery.

- 30. A method for guiding a medical device having a corewire within the lumen of a tube and a torque coupler that rotationally couple the tube and the corewire, the method comprising engaging an element of the torque coupler associated with the corewire with an element of the torque coupler associated with the tube.
- 37. An embolism protection device comprising a corewire and a bundle of fibers fastened together at a first end that is free to move relative to the corewire and fastened collectively to the corewire at a second end wherein the bundle of fibers have a configuration with the fibers being generally aligned and wherein the respective ends of the fiber bundle are twisted relative to each other about an axis aligned along the corewire.
