Abstract

An anchor balloon for conducting peripheral vascular disease procedures in an remote entry point such as an opposite extremity is provided, and includes a flexible catheter, which includes a wire lumen and a balloon lumen with a control port for connecting to balloon control and a balloon inflation port; and, a compliant anchor balloon connected near the flexible catheter distal end. A method for treating peripheral vascular disease in an opposite femoral artery includes inserting a first flexible catheter with flexible guide wire into an artery on an opposite side, advancing the flexible catheter to a location upstream of the surgery location, advancing the guide wire through the catheter to an anchor location, withdrawing the first catheter leaving the wire in place, inserting an anchor balloon catheter over the wire to an anchor location, withdrawing the first wire; inflating the anchor balloon against the arterial walls, inserting a stiff guide wire through the anchor balloon catheter to the point of surgery, deflating the anchor balloon, and withdrawing the anchor balloon catheter while leaving the stiff wire in place for further procedures.

Claims

1. An anchor balloon catheter for conducting vascular procedures upon arteries in an extremity from an opposite entry point, comprising:

a flexible catheter including a proximal end and a distal end, and a plurality of lumens, said flexible catheter having length sufficient to reach a selected location in a patient'"'"'s opposite extremity, wherein said plurality of lumens comprises at least;

a wire lumen including a wire access port accessible to a surgeon at said flexible catheter proximal end and a wire exit port at said flexible catheter distal end, and

a balloon lumen, said balloon lumen including a balloon control port for connecting to balloon control means accessible to a surgeon at said flexible catheter proximal end and a balloon inflation port near said flexible catheter distal end; and

,

a compliant anchor balloon connected to said flexible catheter at a selected distance from said flexible catheter distal end and in fluid communication with said anchor balloon control port via said anchor balloon operating port.

2. The apparatus of claim 1, wherein said flexible catheter outer diameter is less than or equal to approximately 1 mm (0.039 inches).

3. The apparatus of claim 1, wherein said flexible catheter is approximately 90 cm (35.4 inches) in length.

4. The apparatus of claim 1, wherein distance of the distal end of said anchor balloon from the distal end of said flexible catheter lies in the range 10 mm (0.4 inches) to 20 mm (0.8 inches).

5. The apparatus of claim 1, wherein said anchor balloon is approximately 10 mm (0.4 inches) in length and has a deflated diameter of approximately 4 mm (0.2 inches) and an inflated diameter of approximately 8 mm (0.3 inches).

6. The apparatus of claim 1, wherein the balloon diameter when fully inflated is such as to occlude the vascular channel at said selected location.

7. The apparatus of claim 1, wherein the wire lumen diameter is less than or equal to 0.91 mm (0.035 inches).

8. An anchor balloon catheter, comprising:

a flexible catheter insertable into a femoral artery having a port end and a distal end, wherein said port end is provided with a plurality of ports and wherein said catheter is provided with a plurality of lumens corresponding to said plurality of ports;

inflatable compliant stabilizing means provided near said distal end of said flexible catheter, in fluid communication with one of said lumens and one of said ports, which occludes the artery when inflated and thereby stabilizes said flexible catheter to allow a stiff guide wire to pass through said flexible catheter from one extremity to the opposite extremity.

9. A method for treating peripheral vascular disease in an opposite femoral artery, comprising the steps of:

inserting a short entry sheath into an entry point in a near femoral artery;

inserting a first flexible catheter including a flexible guide wire through said sheath and advancing said omni catheter past the U-turn of the common iliac artery to a location in the opposite channel of the common iliac artery;

advancing said flexible wire through said omni catheter into said opposite femoral artery;

withdrawing said first flexible catheter through said sheath over said flexible guide wire while leaving said flexible guide wire in place;

inserting an anchor balloon catheter through said sheath and over said flexible guide wire using said wire lumen of said anchor balloon catheter, and advancing said anchor balloon catheter along said flexible guide wire until said anchor balloon is located at said anchor location;

withdrawing said flexible guide wire through said anchor balloon catheter and said entry sheath;

inflating said anchor balloon against the arterial walls at said anchor location;

inserting a stiff guide wire through a wire lumen within said anchor balloon catheter and advancing said stiff wire past said inflated anchor balloon to the selected location for the vascular femoral surgery;

deflating said anchor balloon;

withdrawing said anchor balloon catheter through said sheath over said stiff wire while leaving said stiff wire in place; and

,

withdrawing said entry sheath over said stiff wire while leaving said stiff wire in place;

wherein said stiff wire is then available to insert a long sheath or therapeutic catheter for therapeutic procedures.

10. The method of claim 9, wherein said flexible guide wire is less than or equal to 0.035 inches (0.91 mm) in diameter.

11. The method of claim 9, wherein said stiff guide wire is less than or equal to 0.035 inches (0.91 mm) in diameter.

12. A method for performing vascular surgery on a patient, comprising the steps of:

inserting a first flexible catheter including a flexible guide wire through into an entry point in an artery on the opposite side of said patient;

advancing said first flexible catheter through the arteries of said patient to a location upstream of the intended location of said vascular surgery;

advancing said flexible guide wire through said first flexible catheter to an anchor location;

withdrawing said first flexible catheter over said flexible guide wire while leaving said flexible guide wire in place;

inserting an anchor balloon catheter over said flexible guide wire using said wire lumen of said anchor balloon catheter, and advancing said anchor balloon catheter along said flexible guide wire until said anchor balloon is located at said anchor location;

withdrawing said flexible guide wire through said anchor balloon catheter;

inflating said anchor balloon against the arterial walls at said anchor location;

inserting a stiff guide wire through a wire lumen within said anchor balloon catheter and advancing said stiff wire past said inflated anchor balloon to the intended location for the vascular surgery;

deflating said anchor balloon;

withdrawing said anchor balloon catheter over said stiff wire while leaving said stiff wire in place;

wherein said stiff wire is then available to insert a long sheath or therapeutic catheter for therapeutic procedures.
