Abstract:     A vascular interventional device may be introduced over a guidewire into a vessel of the cardiovascular system of a patient. This device includes a hollow, flexible tube having a proximal end and a distal end that is adapted to selectively engage a target vessel of the cardiovascular system of the patient. This tube also includes a lumen that is continuous from the proximal to the distal end, and has an end hole in the distal end that is in fluid communication with the lumen. The device also includes a hollow vessel dilator that is adapted for insertion into and through the tube and over the guidewire. The dilator has an inside diameter that is slightly larger than the guidewire and an outside diameter that is slightly smaller than the diameter of the lumen of the tube. The distal end of the dilator is adapted to accommodate vascular entry over the guidewire, and the dilator is adapted to dilate the vessel to accept the tube. The device also includes a hub at the proximal end of the tube. The hub includes an end port through which a second interventional device having an outside diameter smaller than the diameter of the lumen may be introduced into the lumen of the tube. The hub also includes a side port through which a fluid agent may be injected for delivery through the lumen and out the end hole of the tube. A sealing mechanism is also provided in the hub to prevent air from entering the tube and blood and other fluids from leaking out of the tube through the hub. A pair of vascular interventional devices, at least one of which is constructed according to the invention, may be utilized to treat or study a cardiovascular condition, or to measure the blood pressure across a vascular segment.

First Claim:
Show all 16 claims
What is claimed is:     1. A vascular interventional device that may be introduced over a guidewire into a vessel of the cardiovascular system of a patient, said device comprising:
  • (a) a hollow, flexible tube having:
    • (i) a proximal end;
    • (ii) a distal end that is adapted to selectively engage a target vessel of the cardiovascular system of the patient, which target vessel is different from the vessel of entry;
    • (iii) a lumen that is continuous from the proximal to the distal end;
    • (iv) an end hole in the distal end thereof that is in fluid communication with the
    • (v) an axis along its length; lumen;
  • (b) a hub at the proximal end of the tube, said hub including:
    • (i) an end port through which a second interventional device having an outside diameter smaller than the diameter of the lumen may be introduced into the lumen of the tube; and
    • (ii) a side port through which a fluid agent may be injected for delivery through the lumen and out the end hole of the tube, said side port being adapted to rotate, with respect to the tube, about the axis of the tube;
    • (iii) a sealing mechanism that prevents air from entering the tube and blood and other fluids from leaking out of the tube through the hub;
  • (c) a flexible, hollow vessel dilator that is adapted for insertion into and through the tube and over the guidewire, said dilator:
    • (i) having a proximal end and a distal end, said distal end being adapted to accommodate vascular entry over the guidewire;
    • (ii) having an inside diameter that is slightly larger than the guidewire;
    • (iii) having an outside diameter that is slightly smaller than the diameter of the lumen of the tube;
    • (iv) being adapted to dilate the vessel to accept the tube; and
    • (v) being adapted for secure but removable attachment to the hub at its proximal end.
