Patent number: 7699862Abstract: The resheathing tool includes a flexible tubular body with a wall, an inner bore, and an aperture formed in the wall. The tool can be used to facilitate the unsheathing of the vasoocclusive device from the reloadable slotted introducer sheath by threading a proximal portion of the sheath out the aperture of the tool while sliding the vasoocclusive device distally through the sheath. The tool facilitates resheathing of the vasoocclusive device by introducing the vasoocclusive device through the slot of a reloadable slotted introducer sheath into the sheath by threading the reloadable slotted introducer sheath through the aperture and into the inner bore of the tool while threading the vasoocclusive device through the inner bore of the tool. At the same time, the resheathing tool prevents the elongated vasoocclusive device from moving out of the reloadable slotted introducer sheath through the slot.Type: GrantFiled: January 25, 2005Date of Patent: April 20, 2010Assignee: Micrus CorporationInventor: Marcelino Gorospe

Patent number: 7645275Abstract: The variable stiffness heating catheter includes a heating catheter shaft including at least one electrically conductive member, a reinforcing tube with apertures formed around the surface of the reinforcing tube, and at least one coaxial outer layer of a polymer, metal, or both for providing desired variations in stiffness along at least a portion of the length of the shaft. The apertures can be formed as axial or helical slits in the surface of the reinforcing tube, and the reinforcing tube can also be formed to be tapered at the point where the apertures are formed in the reinforcing tube to provide a heating catheter that is torqueable and pushable at the proximal end, yet soft and flexible at the distal end.Type: GrantFiled: May 12, 2006Date of Patent: January 12, 2010Assignee: Micrus CorporationInventors: Michael J.

Publication number: 20100004731Abstract: The apparatus for deployment of a therapeutic device such as a micro-coil detachably mounts the therapeutic device to a distal portion of a pusher member. In one embodiment, the therapeutic device is detachably mounted to the distal portion of the pusher member by a tubular collar that can be heated by a heater such as an electrical resistance coil to expand the collar and release and deploy the therapeutic device. The apparatus for deployment of a therapeutic device such as a micro-coil may also provide for a pusher member and a connector fiber for securing the therapeutic device to the pusher member. The connector fiber passes through a heater within the distal portion of the pusher member, for heating and breaking the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.Type: ApplicationFiled: August 20, 2009Publication date: January 7, 2010Applicant: MICRUS CORPORATIONInventors: Deepak Gandhi, Kamal Ramzipoor

Publication number: 20080021535Abstract: A stent includes a cylindrical frame consisting of a series of helical winds containing a pattern of alternating zigzag bends. The frame may be made of resilient wire or from a piece of laser cut hypo tubing by placing the stent over a notched portion of a pusher catheter member, and retained on the pusher catheter member by a release wire threaded through the pusher catheter member and over the stent. The stent may also be deployed by placing the stent over a pusher catheter member having opposing notched portions, and retaining the stent and pusher catheter member in a delivery catheter, which can be withdrawn when stent reaches the site to be treated to release the stent.Type: ApplicationFiled: August 13, 2007Publication date: January 24, 2008Applicant: MICRUS CORPORATION, A DELAWARE CORPORATIONInventors: Eric Leopold, Josef Friedmann, Neal Padilla

Patent number: 7070608Abstract: The vasoocclusive coil has a primary coil configuration with a helical loop at at least one end. The terminal helical loop can have a J-shaped configuration, preferably with a loop diameter of about 2 mm. The coil is preferably provided with helical loops at both ends, with helical loop at the proximal and distal ends of the coil acting as an anchor to prevent the coil from coming free from the location being treated and escaping into the vasculature. In a presently preferred embodiment both ends of the coil have a J-shape. In another presently preferred aspect, the vasoocclusive coil includes one or more loops intermediate the ends of the coil. The device is formed from a multi-stranded micro-cable having a plurality of flexible strands of a shape memory material and at least one radiopaque strand.Type: GrantFiled: October 2, 2001Date of Patent: July 4, 2006Assignee: Micrus CorporationInventors: Daniel R.
