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: Methods and devices to remove thromboembolic material from the human body using rotational energy and aspiration are disclosed. A thromboembolic removal system includes an extraction device and drive unit. The extraction device is introduced to the treatment area and activated by the drive unit to separate, break apart, loosen or soften thromboembolic material and to facilitate its aspiration outside the patient.

Abstract: A thrombectomy system includes a catheter having a proximal end and a distal end, a valve in fluid communication with the catheter, and a cutting instrument associated with the distal end of the catheter. The cutting instrument may be configured for axial and/or rotational motion. A controller of the system may be configured to detect operational parameters of the cutting instrument. The controller may determine whether the cutting instrument is engaging with occlusive material based on the detected operational parameters. The controller may operate the valve in one or more operating modes to alter a level of pressure in the catheter based on whether the cutting instrument is engaging with the occlusive material.

Abstract: A dynamic aspiration method including engaging a distal end of an aspiration catheter against an occlusion in a blood vessel, applying a vacuum through an aspiration lumen of the aspiration catheter using a vacuum source coupled to a proximal end of the aspiration lumen by a connecting tube, whereby portions of the occlusion are drawn into the aspiration lumen, through the connecting tube and into a collection receptacle by the vacuum source, sensing flow through the connecting tube, and automatically generating pressure differentials when a clog or restricted flow is detected.

Abstract: Automatic synchronization of a magnetic field transmitter and receiver is performed to resolve phase ambiguity so that phase information, used in determining the position and orientation of the receiver, may be derived and maintained. Inertial measurement unit (IMU) information is used to infer gravity-relative orientations of the transmitter and receiver, which are then used as constraints in the synchronization process to determine the position and orientation of the receiver from all four possible solutions or variations. The variation that best conforms to the IMU orientations is chosen as the sync candidate.

Abstract: An aspiration thrombectomy system includes an aspiration catheter configured to accommodate fluid and having a proximal end and a distal end. The system includes connection tubing coupled to the aspiration catheter and configured to act as a common conduit for fluid communication. The system further includes controllable valves operable to control a level of pressure, and pressure sensors positioned downstream from the distal end of the aspiration catheter. A controller is configured to determine a vascular pressure level of the patient, and to determine one or more therapeutic-benefit metrics associated with continuance of the aspiration thrombectomy procedure.

Abstract: An aspiration thrombectomy system including an aspiration catheter having a proximal end and a distal end, the aspiration catheter having a lumen to accommodate fluid, a vacuum source including a controllable vacuum valve, a tubing connected to the aspiration catheter, and a controller configured to detect a change in a catheter diameter corresponding to a change in the connection between the aspiration catheter and the tubing. The controller is configured to change a pulsation protocol associated with the aspiration catheter responsive to the change in the catheter diameter, and the pulsation protocol specifies pressure variations and pressure patterns to modulate the vacuum valve to change a level of vacuum at the distal end of the aspiration catheter.
