A device for closing an aperture in a vessel wall comprising a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture and having a first opening. A first retainer is positionable external of the vessel. A flexible connecting member operatively connects the covering member and the first retainer, wherein the first opening of the covering member is configured to restrict movement of the connecting member.

Vascular hole closure device

A surgical delivery instrument for delivering a vascular hole closure device having a hole covering member. The delivery instrument comprises a housing, a plunger and an advancer movable within the housing, the advancer having a first portion and a distal portion hingedly connected to the first portion and forming a casing for supporting the hole covering member. Distal movement of the advancer pivots the casing from an angled position to a more linear position to change the orientation of the covering member from a transverse position to a more aligned position. The plunger is advanceable to advance the covering member into the vessel.

Vascular hole closure delivery device

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 device for closing an aperture in a vessel wall comprising an elongated member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture. The elongated member has a dimension to prevent egress of fluid through the aperture. A material forms two curved legs having ends positionable external of the vessel. The legs curve in different directions and a retention portion is formed in the material to retain the legs during placement of the elongated member inside the vessel.

A dialysis catheter including a first portion having a first diameter, an elongated distal portion having a second smaller diameter, and a transition portion The first portion includes first and second independent blood withdrawal lumens extending in the first portion, the first withdrawal lumen terminating in the transition portion in a first terminal opening and the second withdrawal lumen terminating in a second terminal opening, the first and second terminal openings being radially spaced and axially adjacent. A longitudinally extending blood delivery lumen extends in the first portion and terminates in a delivery opening in the distal portion of the catheter, the first and second terminal openings positioned proximally of the delivery opening and each of the first and second terminal openings having a curved wall surrounding a portion of the terminal opening.

Dialysis catheter

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.
