A vessel filter having a first region and a second region, the filter movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. The first region has a filter portion having a converging region to direct particles toward the center of the filter and includes a plurality of spaced apart filter struts. The struts each have a strut height defined as a distance between a first wall and a second wall. A plurality of hooks are at the second region, the hooks having a vessel penetrating tip and a width greater than the width of the strut from which it extends such that the penetrating tip portion of the hook extends beyond the first wall.

Vein filter

A vessel filter comprising a first region and a second region wherein the filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. A first region has a filter portion having a converging region to direct particles toward the center of the filter and the second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the first end portion. The second region includes a vessel engaging portion at the second end portion. The first region includes a plurality of spaced apart elongated struts with adjacent struts being joined.

A system is provided that includes an elongated introducer navigable through body vessels of a human subject and a pusher component for incorporation within the introducer. The pusher component includes a tubular portion with a slotted section. A radiopaque marker is secured to at least a portion of the slotted section such that an outer surface of the radiopaque marker is substantially flush with an outer surface of the tubular portion immediately proximal and/or immediately distal the radiopaque marker. According to a method of manufacturing such a component, the slotted section is formed by a laser cutting operation and a pre-assembly radiopaque marker member is crimped onto the slotted section.

A vessel filter having a first region having a first set of struts forming a mounting portion and a filter portion having a converging region at a first portion to direct particles toward the center of the filter. The mounting portion is flared in the expanded position to have a transverse dimension increasing toward a second portion opposite the first portion. A second set of struts forms a second mounting portion flared in the expanded position. A plurality of spaced apart struts extend between the first and second regions.

A system is provided that includes an elongated introducer navigable through body vessels of a human subject and a pusher component for incorporation within the introducer. The pusher component includes a tubular portion with a spiral ribbon. A radiopaque marker is secured to at least a portion of the spiral ribbon such that an outer surface of the radiopaque marker is substantially flush with an outer surface of the tubular portion immediately proximal and/or immediately distal the radiopaque marker. According to a method of manufacturing such a component, the spiral ribbon is formed by a spiral cutting operation and a pre-assembly radiopaque marker member is crimped onto the spiral ribbon. According to another method of manufacturing such a component, the spiral ribbon is formed by winding a filament and a pre-assembly radiopaque marker member is crimped onto the spiral ribbon.

An implantable medical device delivery system is provided with a carrier member having a proximal portion, a distal portion, and a frangible portion intermediate the proximal and distal portions. The frangible portion includes at least one notch providing a break hinge. A locking member is fixedly secured to the proximal portion of the carrier member and is releasably connected to an implantable medical device at or adjacent to the distal portion of the carrier member. In use, the implantable medical device is positioned generally adjacent to a target location of a body vessel and the frangible portion is broken about the break hinge. The proximal portion of the carrier member is then moved away from the distal portion to retract the locking member, thereby deploying the implantable medical device.

Use of an interventional medical device system operable while within a body vessel is provided with a generally hollow tubular proximal portion, distal portion, and intermediate portion. The proximal portion and at least part of the distal portion remains outside of the body in use, with the remainder of the distal portion positioned within the body. The intermediate portion includes a spiral ribbon having adjacent turns, with at least one frangible bridge member between two adjacent turns. The proximal and distal portions are movable away from each other by elongating the spiral ribbon and, eventually, breaking the frangible bridge member. According to the method of using such a system to deploy an implantable medical device, such as an embolic coil, an actuation member is moved proximally with the proximal portion to disengage a bond or joint between the actuation member and the implantable medical device.

An implantable medical device detachment system is provided with a carrier member having a compressible portion at a distal end thereof. The compressible portion is moved to a compressed condition to allow an engagement member of the system to releasably engage an implantable device, such as an embolic coil. The carrier member and associated implantable device are fed through a body vessel to a target location, where the device is disengaged from the engagement member. The compressible portion then moves from the compressed condition to an elongated condition to completely separate the implantable device from the engagement member.

A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. An embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes an engagement member attached to the distal end of the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the pusher member. A kicker member which takes the form of a generally U-shaped wire spring which extends from the distal end of the pusher member and is biased so as to lift the retaining ring off of the engagement member to ensure the release of the embolic device when the detachment member is withdrawn from the aperture of the engagement member.
