Publication number: 20130131702Abstract: Disclosed is an apparatus and a method for removable of undesired material from body lumens. The apparatus may be used for fragmenting or removing a thrombus or occlusion from a blood vessel. The apparatus includes first shape segments and second shape segments connected to form a coiled member. A longitudinally extending tether is positioned inside the first shape segments and outside the second shape segments along the length of the coil. Applying a proximal force on the tether produces a change in the shape of at least a portion of the coil from a first generally linear configuration to a second complex three dimensional shape. A method of using the apparatus to engage and remove, or fragment, the thrombus or occlusion is disclosed.Type: ApplicationFiled: January 17, 2013Publication date: May 23, 2013Applicant: MICRUS ENDOVASCULAR CORPORATIONInventor: HOUDIN DEHNAD

Patent number: 8414524Abstract: The long nose manipulatable catheter includes a main lumen, a wire lumen with a push-pull wire therethrough, and a flexible joint region. The catheter section includes a control including a handle and a wire control member engaging the push-pull wire for manipulating the flexible joint region. The push-pull wire may be tapered, having a proximal portion of a first diameter and a smaller diameter distal portion. A coil may be placed around the smaller diameter to prevent buckling of the smaller diameter portion. A strapping coil may also disposed around the outside of the catheter, and an outer covering may be disposed around the strapping coil.

Patent number: 8273073Abstract: A long nose manipulatable catheter is described herein. The catheter generally comprises a flexible joint region defining a main lumen and an adjacent wire lumen. The wire lumen has an opening near or at a distal end of the flexible joint region and a push/pull wire can be pushed or pulled through the wire lumen. The catheter assembly may also comprise at least one radio-opaque marker band for securing the push/pull wire. The joint region has a predetermined length sized to affect a flexure of the joint and is generally located at the distal end of the catheter. The joint region itself may be varied to extend distally from where the braid terminates, or it may extend to encompass a portion of the braid. By varying a length of the joint region, the amount of curvature and flexure of the joint region can be controlled.Type: GrantFiled: September 4, 2009Date of Patent: September 25, 2012Assignee: Micrus Endovascular CorporationInventors: Marc-Alan Levine, Stephen Hebert

Publication number: 20100152837Abstract: The intravascular stent is formed from a composite wire includes an inner core of radiopaque metal, a polymer layer coaxially disposed about the inner core, and an outer metal layer coaxially disposed about the polymer layer. The intermediary polymer layer acts as a barrier material between the inner core and the outer sheath, so that the inner core and outer sheath may be made of dissimilar metallic layers, and the intermediary polymer layer will prevent a galvanic reaction between the inner core and the peripheral metal layer. The intravascular stent has ends flared radially outwardly to prevent radially and longitudinally inward deformation of the ends of the stent when the stent is disposed in a desired location in a patient's vasculature.Type: ApplicationFiled: February 22, 2010Publication date: June 17, 2010Applicant: MICRUS ENDOVASCULAR CORPORATIONInventors: Andre S.
