    Abstract: A catheter system comprising a) an elongate flexible catheter; b) a lumen that extends from a proximal insertion port to a side outlet opening; c) a penetrating guidewire insertable into the proximal insertion port and thereafter advanceable through the lumen and out of the side outlet opening; and d) an orientation element useable to provide an indication of the trajectory on which the penetrating guidewire will advance from the catheter body. Also disclosed are methods for using such catheter to direct the penetrating guidewire out of the side opening and into the true lumen of a blood vessel when bypassing an obstruction in the blood vessel such as a chronic total occlusion (CTO) of an artery.

    Abstract: 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.

    Abstract: A one-way valve prosthesis for percutaneous placement within a vein, the valve including a valve body having an inlet and an outlet with a lumen that extends there between. The valve body is operable to alternate between a closed configuration wherein the valve body has a double cone shape and an open configuration wherein the valve body has a double frustoconical shape. A valve seat if formed within the lumen of the valve body at a midsection thereof. The valve seat is constricted to prevent flow there through when the valve body is in the closed configuration and the valve seat is open to allow flow there through when the valve body is in the open configuration. The valve seat opens in response to an actuation pressure and closes in the absence of the actuation pressure.

    Abstract: 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.

    Abstract: A stent is formed from a wire having an outer member, a radiopaque member lining at least a portion of the outer member inner surface, and a lumen defined by the outer member inner surface or the radiopaque member inner surface. A substance is disposed in the lumen to be eluted through at least one opening disposed through the outer member to the lumen. The radiopaque member may be substantially continuous along the length of the wire or disposed only along portions of the wire such as crowns. In a method for making the stent, a composite wire including an outer member, a radiopaque intermediate member, and a core member is shaped into a stent pattern and processed to remove the core member and optionally portions of the radiopaque intermediate member, without damaging the outer member.
