    摘要： The present invention relates to a device with an ultrasonic-based probe for drilling and coring. The invention uses ultrasonic and subsonic vibrations produced by a frequency compensation coupler or free mass to produce the hammering action of a partially disengaged probe, with a relatively low axial force required. The invention can also be fitted with irrigation and aspiration capabilities. The invention can furthermore be furnished with a body sensor-feedback apparatus, which provides feedback to the operator as to the optimal frequency and power use of the generator. One embodiment of the invention also has a cooling mechanism to keep the drill or coring apparatus at an optimum temperature.

    摘要： A catheter for use with at least two different sizes of wire guides is described. The catheter includes a wire guide lumen sized to receive a first wire guide of a first diameter. The catheter may also include a tip lumen that extends in a distal direction from a first opening in communication with the wire guide lumen to a second opening. The first opening is sized to receive the first wire guide, and the second opening is sized to receive a second wire guide of a smaller diameter than the first wire guide. The catheter also includes one or more longitudinal expansion features capable of radially expanding the tip lumen to receive a wire guide of a diameter up to the first diameter through the second opening. An adapter that may be attached to the catheter by a medical professional is also described.

    摘要： A retrievable device for treatment of a stenotic lesion in a body vessel is disclosed. The device comprises a reticulation portion including a plurality of struts connected together in a singly staggered configuration distally along a longitudinal axis. The plurality of struts of the reticulation portion is configured to fold along the longitudinal axis defining a collapsed state of the device for retrieval. The device further includes an expandable body distally extending from the reticulation portion along an outer diameter for treatment of the stenotic lesion. The expandable body is configured to expand in the open state and collapsed in the collapsed state of the reticulation portion for retrieval. The device further comprises a retrieval stem extending proximally from the reticulation portion for retrieval of the device in the collapsed state.

    摘要： A system and method for occluding an aneurysm formed in a dilatation area of a body vessel are disclosed. The system comprises a wire guide, a core wire, and an occlusion device. The wire guide comprises a proximal end and a distal end, and has a passageway that extends from the proximal end to the distal end. The core wire comprises a distal end and a proximal end, and is disposed through the passageway so that the proximal end of the core wire proximally extends beyond the proximal end of the wire guide. The occlusion device comprises a distal end and a proximal end, and has a deployed state and an undeployed state. The occlusion device has a pre-set spiraled coil shape when in the deployed state in the vessel. The occlusion device is disposed distally from the core wire in the passageway.
