摘要： Devices and methods for limiting the depth to which a penetrator is advanced into an organ or mass of tissue. The device generally comprises a first member and a second member. The penetrator is attached to and extends from a second member. The first member has a penetrator shroud and a hollow bore extending therethrough. The second member is engageable with the first member such that a distal portion of the penetrator extends through the penetrator shroud. The distance to which the penetrator protrudes out of and beyond the distal end of the penetrator shroud is adjustable in accordance with the desired depth of penetration. The penetrator may then be advanced into the organ or tissue mass until the distal end of the shroud abuts against the organ or tissue mass, thereby stopping further advancement of the penetrator. The penetrator may have one or more lumen(s) for aspirating or infusing substances.

摘要： An obstruction removal system for percutaneous removal of clots or obstructions within the vascular system is disclosed. The obstruction removal system includes a multi-lumen catheter with a plurality of circulating capture devices attached to or integral with a drive belt. The circulating capture or interference devices affect removal of the clot or obstruction bit-by-bit through a series of passes. The obstruction removal system may include one or more drive mechanisms, such as a pulley system and/or a vacuum source and/or a pressurization source, on its proximal end for driving the drive belt and capture devices through the catheter in a circulating manner. The obstruction removal system may also include one or more cleaning mechanisms, such as a vacuum chamber and/or a fluid rinse chamber, for removing the captured clot pieces from the capture devices.

摘要： A valve prosthesis for percutaneous placement within a vein is disclosed that includes a valve scaffold and a backflow barrier. The valve scaffold is of a shape memory or resilient material and the backflow barrier is a flap of flexible material attached to the valve scaffold. The valve prosthesis is operable to alternate between open and closed configurations in response to changes in retrograde blood flow pressure. In the open configuration, the valve scaffold has a frustoconical coil shape of consecutive windings with open spaces therebetween and the backflow barrier allows antegrade blood flow through the open spaces. In the closed configuration, the consecutive windings of the valve scaffold are collapsed such that the valve scaffold has a substantially flat profile and the backflow barrier covers the opens spaces of the flattened valve scaffold to prevent retrograde blood flow from leaking there through.

摘要： Artificial valves for use as a venous valve or a heart valve are disclosed. The valve includes a frame including a platform and a valve material coupled to the frame. The valve material is a plurality of filaments or a flap. The valve material is coupled to the frame such that in response to a force in a first direction, e.g. blood flow, the valve material extends in the direct of the force to allow blood to flow past the valve material. In absence of the force in the first direction, the valve material rests against the platform to block blood flow in a direction opposite the first direction.
