    Abstract: A recanalization catheter assembly for recanalization of an occluded blood vessel is disclosed. The recanalization catheter assembly includes an elongate shaft having a tubular portion, a guide member, and a rotary ablation tool. The tubular portion includes a distal opening, from where the rotary ablation tool extends distally. The guide member extends distal of the distal opening and includes a guidewire lumen to receive a guidewire therethrough. The guide member is configured to advance over the guidewire in a subintimal space between a first tissue layer and a second tissue layer of a wall of the blood vessel, while the rotary ablation tool is advanced in a true lumen of the blood vessel.

    Abstract: A heart valve delivery system includes a low-profile catheter having an outer sheath, the outer sheath having therein a stent and a replacement heart valve. In an unemployed configuration, the stent is located distally to the replacement heart valve. Upon deployment, however, the stent and replacement heart valve are expanded and the replacement heart valve is situated within the stent.

    Abstract: A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The recanalization catheter includes first and second mechanically actuatable wings positioned at a distal region of the elongate shaft of the catheter that are actuatable between a retracted position and an expanded position. In the retracted position the mechanically actuatable wings are positioned in first and second elongate channels defined in the elongate shaft, and in the expanded position the mechanically actuatable wings extend outward from the first and second elongate channels. The actuatable wings extend in an arcuate path away from the elongate shaft in the expanded position to be positionable in a circumferential orientation within a subintimal space formed in a vessel wall to automatically orient a lateral port of the elongate shaft toward the true lumen.

    Abstract: A catheter is disclosed, which is capable of delivering embolization beads for treating uterine fibroids. The elongate catheter shaft includes a radially expandable portion at its distal end, which can expand radially locally when an embolization bead passes through it. In some cases, the catheter shaft includes a non-expandable portion, with an inner diameter comparable to the bead diameter, between the handle and the radially expandable portion. In some cases, the radially expandable portion is made from a tubular braid, stretched longitudinally over a mandrel, and encased in a lubricious soft polymer while still stretched. In other cases, the radially expandable portion is made from a slotted nitinol tube, encased in a lubricious soft polymer below the nitinol transition temperature. The polymer is thick enough to prevent the encased element from returning to its unstretched diameter or a larger size above the transition temperature.

    Abstract: A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The catheter includes an inflatable balloon mounted on a distal end region of the catheter shaft of the catheter. The catheter shaft includes a guidewire lumen having a distal opening and a lateral opening in a distal region of the catheter shaft proximal of the distal opening, and an inflation lumen in fluid communication with the balloon. The balloon is configured to be inflated in the subintimal space to a first inflation state at inflation pressures below a threshold inflation pressure to orient the lateral opening toward the lumen of the blood vessel, and inflated to a second inflation state at inflation pressures above the threshold inflation pressure. The catheter includes means for retaining the balloon in the first inflation state at pressures below the threshold inflation pressure.

    Abstract: A valve that includes an expandable valve body defining a lumen and a longitudinally moveable obstructer retained within the lumen of the valve body between the proximal and distal ends of the valve when the valve is in an expanded configuration. The valve, in the collapsed configuration, is delivered to a native valve site by a catheter where the valve body is expanded to anchor the valve at the valve annulus and the collapsed obstructer is subsequently expanded so that the valve is in the expanded configuration.
