Appl. No.:

09/491273

Assignee:

Scimed Life Systems, Inc. - Maple Grove MN

International Classification:

A61M 2900

US Classification:

606200

Abstract:

A thrombus filter which can be securely fixed in a selected location in the vascular system of a patient and removed when no longer required. The thrombus filter includes a plurality of struts which radiate from a body portion to form the generally conical shape of the thrombus filter. The thrombus filter includes anchor members joined to the free end of each strut. The thrombus filter includes an insulating layer substantially covering the thrombus filter including the body portion, the struts and the anchor members. The insulating layer includes an opening proximate the anchor members. The opening in the insulating layer creates a conductive path between the thrombus filter and the patients body. When removal of the thrombus filter is desired, a first electrical conductor forms an electrical connection with the body portion of the thrombus filter. A second electrical conductor forms an electrical connection with the patients body.

International Classification:

A61M 2900

US Classification:

606200, 128899

Abstract:

A vascular filter comprises an emboli-capturing portion having a set of helical filter-wires joined at a central region and extending in a given direction along the blood vessel in a diverging relationship to the axis of the filter, the wires terminating in free ends constructed to engage the walls of said vessel. A major mid-portion of the length of the free ended wires are of generally helical form, cooperatively related to form an effective emboli capturing array. Anchoring is accomplished by a separate assembly formed of struts and anchoring devices. A parallelogram supporting strut assembly and other means for providing linear engagement with the wall of the vena cava are shown. The parallelogram structure is shown to have filter capability by itself as well.

Assignee:

SciMed Life Systems, Inc. - Maple Grove MN

International Classification:

A61M 2900

US Classification:

606200

Abstract:

A thrombus filter configured for placement within a blood vessel lumen defined by a blood vessel wall. The thrombus filter includes a body member, and a plurality of wires. Each wire has a joined end and a free end. The joined end of each wire is fixedly attached to the distal portion of the body member. Each wire radiates away from the body member along a generally helical path of expanding diameter. The shape of each wire may be generally described as a spiral, or a helix of expanding diameter. The wires radiate away from the body member to form a generally conical filtering portion which includes a plurality of open cells. The thrombus filter may be removed using minimally invasive methods when such removal becomes desirable. A method of removing the thrombus filter is disclosed.

International Classification:

A61M 29/00

US Classification:

606200

Abstract:

A recoverable thrombosis filter that may be recoverable by a single recovery procedure. It can include a plurality of thrombosis filtering elements that are shaped in a predetermined manner and which are joined at one end and are deployed about a longitudinal axis to form a generally conical structure. The filtering elements can include shaped ends for engaging an inner lumen wall.

International Classification:

A61M 2900

US Classification:

606200

Abstract:

A self-centering blood clot filter is provided. The filter includes an anchoring portion including a generally cylindrical radially expandable body including an axial lumen extending therethrough. The filter further includes a filtering portion including a conical body concentrically aligned within the axial lumen of the anchoring portion. The conical body of the filtering portion is tapered to form a distal tip. As such, the blood clot filter can be properly centered within the lumen of a vessel for effective lysing of blood clots.

International Classification:

A61M 2900

US Classification:

606200

Abstract:

A blood clot filter comprising: an anchoring portion comprising a generally cylindrical self-expanding body formed from resilient material, the generally cylindrical body having proximal and distal ends and defining an axial direction and having a structure of variable size diameter expandable from a low-profile compressed condition to a larger profile expanded condition, wherein the resilient material urges the generally cylindrical body to radially expand and to thereby apply anchoring radial force against the inner wall surface of the blood vessel; and a generally conical filtering portion axially aligned with the generally cylindrical body having an open proximal end coupled to the distal end of the anchoring portion and having an apical distal end. Also disclosed is a blood clot filter having one or more hooks fixedly coupled to the anchoring portion and formed from compliant material having an original shape that bends under stress yet returns to its original shape when unstressed. The hooks respectively tend to project from the anchoring portion at an acute angle with respect to the axial direction for engagement with a vessel wall.
