Publication number: 20140257245Abstract: Embolectomy catheters, rapid exchange microcatheters, systems and methods for removing clots or other obstructive matter (e.g., thrombus, thromboemboli, embolic fragments of atherosclerotic plaque, foreign objects, etc.) from blood vessels. This invention is particularly useable for percutaneous removal of thromboemboli or other obstructive matter from small blood vessels of the brain, during an evolving stroke or period of cerebral ischemia. In some embodiments, the embolectomy catheters of this invention are advanceable with or over a guidewire which has been pre-inserted through or around the clot. Also, in some embodiments, the embolectomy catheters include clot removal devices which are deployable from the catheter after the catheter has been advanced at least partially through the clot. The clot removal device may include a deployable wire nest that is designed to prevent a blood clot from passing therethrough.Type: ApplicationFiled: May 23, 2014Publication date: September 11, 2014Applicant: MicroVention, Inc.Inventors: Robert F. Rosenbluth, George R. Greene, JR., Brian J. Cox, Thomas S. Sternweiler, Sean L. Chow, Richard R. Monetti, Teresa L. Halverson, Maricela D. Walker, Robert Pecor

Patent number: 7048719Abstract: A resheathing apparatus for a tube that is insertable through an endovascular catheter includes a guide that has a proximal end, a distal end, at least one lumen extending from the proximal end to the distal end, and a branch extending away from the lumen at one end of the guide. A sheath may be placed over the tube by sliding the resheathing apparatus along the length of the tube. The resheathing apparatus may also include a guide tube that fits over the branch of the guide and directs a sheath over the tube that is insertable through an endovascular catheter. The resheathing apparatus may be used with vascular embolization devices, and may be used with devices that are delivered via microcatheter systems. Methods of using the resheathing apparatus are also disclosed.Type: GrantFiled: June 7, 2002Date of Patent: May 23, 2006Assignee: MicroVention, Inc.Inventor: Richard R. Monetti

Patent number: 6030397Abstract: A miniaturized brush particularly adapted for medical use formed at the distal end of an elongated brush drive shaft having a hollow lumen formed therein for introduction over a guidewire. The brush drive shaft is enclosed in the lumen of a brush delivery catheter and other components of a brush sub-assembly adapted to deliver infusate through the catheter lumen and to be coupled to a drive motor unit for rotating the brush drive shaft and brush. The brush bristles of the distal brush are adapted to be garaged in a distal end section of the brush delivery catheter lumen during introduction through a body lumen. The brush bristles are formed of a thin sheet of rigid plastic material that is shaped to have a plurality of fringe elements extending in parallel from a mounting web. The mounting web is wound about and attached to a distal end section of the drive shaft outer circumference so that the fringe elements extend outward from the drive shaft surface and obliquely of the drive shaft axis.Type: GrantFiled: December 21, 1998Date of Patent: February 29, 2000Assignee: Micro Therapeutics, Inc.Inventors: Richard R. Monetti, Robert A. Pecor, Thomas R. Sternweiler, Brian M. Strauss
