Abstract
True lumen reentry devices and methods useable for redirecting a guidewire from a subintimal tract within a wall of a blood vessel into the true lumen of the blood vessel. A reentry catheter device comprises a main catheter shaft having at least one guidewire outlet aperture with at least one side tube located on a distal portion of the main catheter shaft. The side tube(s) is/are tracked over initially inserted guidewire(s) to advance a distal portion of the reentry catheter device into the subintimal tract with a guidewire
Claims21
A blood vessel lumen reentry device comprising:
- a catheter having a distal end, a right side, a left side, a top side and a bottom side;
- a guidewire exit port located in the bottom side of the catheter a spaced distance from its distal end;
- a lumen extending from the distal end of the catheter to at least the guidewire exit port;
- a rotational orientation indicator useable for determining the rotational position of the guidewire exit port when positioned within the blood vessel of a human or animal subject;
- a side tube on either the right or left side of the catheter adjacent to the exit port, said side tube having a proximal end opening, a through lumen and a distal end opening.
A blood vessel lumen reentry device comprising:
- a catheter having a distal end, a right side, a left side, a top side and a bottom side;
- a lumen extending through the catheter;
- a first guidewire exit port located in the top side of the catheter a spaced distance from its distal end;
- a second guidewire exit port located in the bottom side of the catheter a spaced distance from its distal end;
- a rotational orientation indicator useable for determining the rotational positions of the first and second guidewire exit ports when positioned within a blood vessel of a human or animal subject;
- a first side tube attached to the right side of the catheter adjacent to the first and second exit ports, said first side tube having a proximal end opening, a through lumen and a distal end opening;
- and
- a second side tube attached to the left side of the catheter adjacent to the first and second exit ports, said second side tube having a proximal end opening, a through lumen and a distal end opening.
