Abstract: A target substance, such as a thrombus, is removed from a patient's body via minimally invasive technique. A catheter is maneuvered and positioned near the target substance. The catheter may have a soft, atraumatic tip constructed from a metallic backbone covered by a polymer. Target substances are drawn into the catheter via an aspiration source. Near the catheter's distal end, a blade and opposing surface are housed within the catheter, and the blade moves relative to the opposing surface within the catheter lumen in order to fragment the target substance. The substances are fragmented within the catheter into discreet and relatively uniform particles. The aspiration source, which helps ensnare target substances, also serves to evacuate the substance fragments from the patient's body.

Abstract: A method and apparatus for reducing magnetic tracking error in the position and orientation determined in an electromagnetic tracking system is disclosed. In some embodiments, a corrected position and orientation is blended with an uncorrected position and orientation based upon the calculated probability of each. To determine a corrected position and orientation, data from an IMU in the receiver is used to obtain a constraint on the orientation. In other embodiments, the amount of detected error due to electromagnetic distortion is measured. Any error is first assumed to be from “floor distortion,” and a correction is applied. If the error is still deemed too great, a constraint is again obtained from IMU data. Using this constraint, another correction for the distortion is made. The solution from this correction may be blended with a standard solution and the solution from the floor distortion to arrive at a final solution.

Abstract: Soft embolic implants exhibiting secondary shapes are disclosed. Some of the embolic implants exhibit progressively increasing softness from the distal end to the proximal end of the coil. The embolic implants have a primary coil, an optional second coil, a shape wire, and a stretch resistant fiber disposed in the lumen of the primary coil. An optional distal support wire is also disclosed. The embolic implants include a proximal constraint assembly configured to be releaseably retained by a delivery device. Disposed near each end of some of the implants are elliptical hole washers through which the shape wire and the stretch resistant fiber are threaded. The embolic implants have a primary, linear configuration for delivery through an implant tool, and a secondary configuration after deployment from the implant tool. The secondary shape can be J-shaped, helical, spherical, complex, or a combination of shapes.

Abstract: Embolic coil implant systems and methods whereby coils are mechanically detachable are disclosed. The coils include a retention element that may be releasably retained within the distal end of an implant tool. The implant tool may include a fulcrum configured to engage a first filament and prevent the release of the coil when the first filament is engaged. Alternatively, an urging means and aperture may be disposed within the sidewall of the implant tool, and a first filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn. The implant tool may also include an alignment member for aligning the first filament.

Abstract: A system for mechanically deploying intraluminal implants is disclosed. The system is used with an implant that is delivered and/or deployed via a pull wire and includes a handle having a funnel and receiving channel for receiving the pull wire, a slider having a thumb grip and a wedge, and a shuttle having a grabber for grasping the pull wire. The thumb grip is pulled proximally to retract the wedge to cause the grabber to grasp the wire and retract the shuttle but not the wire. An extension spring linked between the slider and the shuttle abruptly pulls the shuttle to retract the pull wire after the slider is fully retracted.

Abstract: An aneurysm occlusion system includes a device positionable within a cerebral blood vessel covering a neck of an aneurysm on the blood vessel. The device includes an expandable tubular element having a lumen surrounded by a sidewall including a plurality of gaps. When expanded, the tubular element includes longitudinal standards arrayed helically in a proximal to distal direction. The standards support struts and the gaps are defined between adjacent struts and are sufficiently large to permit delivery of embolic coils or other embolic materials therethrough.

Abstract: Vessel occlusion coils disclosed that have a primary configuration for delivery and a secondary configuration for deployment that is conferred upon the devices by a stretch resistant member. In the secondary configuration, the stretch resistant member forms a stiffer coil and may have a greater diameter, and a more complex shape having some interior space, at one end than at the other end, for improved anchoring of the device in the vessel. The methods include intravascular delivery and deployment for implanting one or more vessel occlusion devices.
