Abstract: A blood filter delivery system for delivering a filter into a vein from either a femoral or jugular access. The preferred system includes an introducer and a push-rod with a spline member disposed along the push-rod and a pusher member disposed on a distal end. The spline member has a main body, first and second boss portions spaced apart along the longitudinal axis to provide a gap for retaining anchor members of the filter during delivery via the introducer. In an alternative embodiment, a preferred filter includes first and second filter structures diverging in opposite directions. A link is connected to portions of each of the first and second filter structures so that each filter structure can be independently collapsed into a generally cylindrical shape.

Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.

Abstract: An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.

Abstract: A method includes providing microvalve device having inner and outer catheters, and a filter valve attached to the distal end of the inner and outer catheters. Longitudinal displacement of the inner catheter relative to the outer catheter moves the filter valve from a non-deployed configuration to a deployed configuration. With the inner catheter longitudinally advanced a first amount relative to the outer catheter, the filter valve is in a reduced first diameter for advancement of a guidewire to a target location. Once the filter valve reaches the target location, the inner catheter is moved relative to the outer catheter such that the filter valve assumes a larger second diameter. A therapeutic agent is infused through the inner catheter and beyond the filter valve.

Abstract: Self-expandable, woven intravascular devices for use as stents (both straight and tapered), filters (both temporary and permanent) and occluders for insertion and implantation into a variety of anatomical structures. The devices may be formed from shape memory metals such as nitinol. The devices may also be formed from biodegradable materials. Delivery systems for the devices include two hollow tubes that operate coaxially. A device is secured to the tubes prior to the implantation and delivery of the device by securing one end of the device to the outside of the inner tube and by securing the other end of the device to the outside of the outer tube. The stents may be partially or completely covered by graft materials, but may also be bare. The devices may be formed from a single wire. The devices may be formed by either hand or machine weaving. The devices may be created by bending shape memory wires around tabs projecting from a template, and weaving the ends of the wires to create the body of the device such that the wires cross each other to form a plurality of angles, at least one of the angles being obtuse. The value of the obtuse angle may be increased by axially compressing the body.

Abstract: Disclosed herein is a removable vena cava filter for capturing thrombi in a blood vessel. The filter includes a plurality of primary struts having first ends attached together at their first ends. The filter also includes a plurality of secondary struts spaced between the primary struts and having third ends attached together along the longitudinal axis. Each secondary strut freely extends from the third end to a fourth end avoiding contact with other secondary struts and primary struts. The filter has an expanded configuration, in which the second arcs of the plurality of secondary struts may define a cavity having a hemiovoid shape, such that an ovoid formed from a reflection of the hemiovoid shape of the cavity does not extend beyond the end boundary of the filter defined by the second ends of the primary struts.

Abstract: An aortic flow diverter or filter is described that diverts particles away from the carotid vessels and right subclavian artery. The diverter includes a stent-like portion formed from a plurality of braided or woven wires that can radially self-expand. The stent-like portion is generally tubular and is fixed over the distal end of a catheter or shaft. A sheath is located over both the catheter and stent-like portion, maintaining the stent-like portion in a compressed configuration. When withdrawn proximally, the sheath releases the stent-like portion, allowing it to expand against the walls of the vessel.

Abstract: A filter device has a single hub and a plurality of filter struts extending in a first longitudinal direction. A plurality of wire loops extend in a second longitudinal direction opposite the filter struts. The filter struts and wire loops each engage the vessel wall of a body lumen when deployed. The wire loops limit the filter device from becoming tilted and embedded in the vessel wall. A retrieval device includes a sheath and a snaring mechanism. The snaring mechanism engages a hook member of the filter and the sheath envelopes the wire loops and filter struts. The sheath will cause the wire loops to bend and fold over the filter struts during retrieval such that the wire loops and filter struts extend in the same longitudinal direction after being enveloped by the sheath.
