Abstract: A guidewire for medical procedures can be stored in a coiled configuration with a clamp. The clamp comprises a guidewire introducer funnel, which can be removably coupled to a hub of a catheter. The clamp comprises an adaptor to allow it to be removably coupled to a guidewire storage tube. The clamp comprises an interior channel configured to allow a guidewire to be advanced therethrough, and the interior channel can be coupled to the introducer and an adaptor that can be coupled to the back end of the clamp.

Abstract: A guidewire for medical procedures can be maintained in a coiled configuration with a clamp. Multiple clamped and coiled guidewires may be stored in a fluid-filled, storage bowl concurrently. Different clamps may have different colors to differentiate the clamps and clamped guidewires. The clamps may be markable to provide additional differentiation. The clamps can further comprise a guidewire introduction funnel and/or a guidewire torquer.

Abstract: A guidewire introducable into a bodily lumen having an obstruction therein is provided. An introducer needle is advanced through tissue and into the bodily lumen. A guidewire is advanced through the introducer and into the lumen. The guidewire is advanced further through the lumen until an atraumatic distal tip of the guidewire encounters an obstruction the distal tip cannot pass in a straight forward manner. The distal tip is pressed against the obstruction such that a flexible segment proximal of the distal tip forms a loop distal of the distal tip. The guidewire is advanced further through the lumen such that the loop of the flexible segment is pushed past the obstruction and the distal tip is pulled distally past the obstruction. A greater diameter guidewire extension can be coupled to the back end of the guidewire, providing function as a larger diameter guidewire.

Abstract: A clot extraction catheter comprises a tubular mesh, a rim attached to the tubular mesh proximal end, control wires, an inner sheath, a clot macerator advancable from the inner sheath, and an outer sheath advancable over the guidewire channel and inner sheath. To extract a clot, the catheter is advanced through the clot. The inner sheath is retracted, allowing the rim and the tubular mesh to expand as well as exposing the clot macerator. The tubular mesh is retracted to capture the clot, constrained proximally by the distal portion of the inner sheath, and retracted with the inner sheath into the outer sheath. The clot macerator breaks apart large clots as the clot is captured, and the tubular mesh is retracted over the clot macerator. The control wires may be manipulated to control the angle of the rim, thereby facilitating clot capture and retraction of the tubular mesh.

Abstract: A clot extraction catheter comprises a tubular mesh, a tapered tip fixed to the tubular mesh distal end, a rim attached to the tubular mesh proximal end, control wires, a guidewire channel, an inner sheath, and an outer sheath advancable over the guidewire channel and inner sheath. To extract a clot, the catheter is advanced through the clot over a guidewire. The inner sheath is retracted relative to the control wires and the tubular mesh, allowing the rim and the tubular mesh to expand. The tubular mesh is retracted to capture the clot, constrained proximally by the distal portion of the inner sheath, and retracted with the inner sheath into the outer sheath. The control wires may be manipulated to control the angle of the rim relative to the longitudinal axis of the sheaths, facilitating clot capture and retraction of the tubular mesh into the sheaths thereafter.

Abstract: A clot extraction catheter comprises an expandable tubular mesh, a tapered tip fixed to the tubular mesh distal end, a self-expanding rim attached to the tubular mesh proximal end, at least three control wires, an inner sheath, and an outer sheath advancable over the inner sheath. To extract a clot, the catheter is advanced through the clot. The inner sheath is retracted relative to the control wires and the tubular mesh, allowing the rim and the tubular mesh to expand. The tubular mesh is retracted to capture the clot, closed once the clot is captured, constrained proximally by the distal portion of the inner sheath, and retracted with the inner sheath into the outer sheath. The control wires may be manipulated to control the angle of the rim relative to the longitudinal axis of the sheaths, facilitating clot capture and retraction of the tubular mesh into the sheaths thereafter.
