Patent number: 7597703Abstract: An occluder catheter having an outer tube, an inner shaft extending slidably through the outer tube, and two expanders attached, respectively, to the distal ends of the inner shaft and the outer tube. The expanders each have a plurality of circumferentially spaced, longitudinally oriented fingers. The fingers each have radially expandable ends and radially constrained ends and the fingers of each expander are interposed with the fingers of the other expander. A flexible non-porous sleeve covers at least the fingers of both expanders. By moving the outer tube with respect to the inner shaft, the occluder is transformable between a collapsed configuration and an expanded configuration wherein the fingers of at least one of the expanders are radially splayed to dilate the sleeve. One embodiment of the invention incorporates a single expander having circumferentially juxtaposed fingers, the expander being mated with a deflector ring.Type: GrantFiled: September 7, 2004Date of Patent: October 6, 2009Assignee: Medtronic Vascular, Inc.Inventor: Ghaleb A Sater

Patent number: 7527637Abstract: An intravascular, distal protection device including a braided mesh that may be selectively transformed between a collapsed configuration, a filter configuration and an occlusive configuration by mechanical or thermal operation. Alternatively, the distal protection device may include a non-inflatable occlusion valve located within the mesh and actuated by the same mechanical operation that transforms the braided mesh.Type: GrantFiled: January 7, 2005Date of Patent: May 5, 2009Assignee: Medtronic Vascular Inc.Inventors: Ghaleb Sater, Allan Steingisser, Jonathan G.

Patent number: 7473274Abstract: A device, system and method for treating cardiac valve regurgitation. The device includes a compression member disposed on a tube and a sleeve rotatably disposed about the tube and the compression member. The sleeve includes a side port, and is rotatable to align the compression member with the side port to transform the compression member from a delivery configuration to a compression configuration. One method includes positioning the compression member adjacent a cardiac valve and rotating the sleeve to align the compression member with the side port to release the compression member from the delivery configuration to the compression configuration to apply a compressive force to the cardiac valve.Type: GrantFiled: November 11, 2004Date of Patent: January 6, 2009Assignee: Medtronic Vascular, Inc.Inventor: Ghaleb Sater

Patent number: 7438716Abstract: Methods and apparatus are provided for moving an intraluminal filament, such as a shaft or hypotube. The actuator includes a housing having a channel therein, the channel having at least a first inclined surface. The actuator also includes a pivotable actuator assembly coupled to the housing and having first and second spaced-apart jaws extending into the channel. The first and second jaws define an opening of a first dimension therebetween. The actuator assembly pivots for urging at least one of the first and second jaws against at least the first inclined surface to transition the first dimension to a second dimension. The method comprises aligning the intraluminal filament between spaced-apart jaws of a pivotable actuator assembly, pivoting the actuator assembly to urge said jaws against at least one surface causing said jaws to grip the intraluminal filament, and further pivoting the actuator assembly to move the intraluminal filament.Type: GrantFiled: October 30, 2003Date of Patent: October 21, 2008Assignee: Medtronic Vascular, Inc.Inventor: Ghaleb A.

Patent number: 7427288Abstract: An embolic protection apparatus having a deflector tube and two expanders each having a plurality of circumferentially spaced, longitudinally oriented fingers. The fingers of each expander have radially constrained ends and radially expandable ends aligned opposite the fingers of the other expander. The deflector tube is disposed within one of the expanders that also has a flexible sleeve covering at least the fingers of the expander. The deflector and the expanders are engageable with each other using compound leverage to transform the apparatus between a collapsed configuration and an expanded configuration wherein the fingers of the covered expander are radially splayed to dilate the sleeve. Also disclosed are a catheter having the protection apparatus and a method of using the catheter.Type: GrantFiled: June 9, 2005Date of Patent: September 23, 2008Assignee: Medtronic Vascular, Inc.Inventor: Ghaleb A.

Patent number: 7303574Abstract: A system for treating a vascular condition, including a hollow guidewire having a central lumen and an inflation hole formed in a sidewall of the hollow guidewire, an occlusion balloon attached proximate to a distal end of the hollow guidewire, and a frictional valve. The frictional valve includes a portion of a core wire positioned within a proximal end of the hollow guidewire, a valve plug attached to the core wire, and at least one frictional plug attached to the core wire proximal to the valve plug. Flow of fluid through the central lumen of the hollow guidewire is controlled by axial translation of the core wire to position the valve plug with respect to the inflation hole, while the frictional plug provides a tailored valve compliance characteristic.Type: GrantFiled: August 7, 2003Date of Patent: December 4, 2007Assignee: Medtronic Vasculor, Inc.Inventor: Ghaleb A.

Publication number: 20070123926Abstract: A guiding catheter includes an elongate shaft with a central bore and a mechanically expandable occluder mounted about the distal end of the shaft. The occluder comprises a flexible membrane supported by an expandable tubular frame. The guiding catheter has a pre-formed curve adjacent the distal end of the shaft. A sheath disposed about the catheter is selectively slidable along the catheter shaft to expand the occluder into sealing engagement with the wall of an artery to provide hemostasis in the artery. Methods of using the guiding catheter are also disclosed.Type: ApplicationFiled: November 28, 2005Publication date: May 31, 2007Applicant: Medtronic Vascular, Inc.Inventors: Ghaleb Sater, Jeffrey Witts
