Balloon method and apparatus for vascular closure following arterial catheterization
First Claim
1. Apparatus for hemostasis of an artery having a puncture after arterial catheterization, the apparatus comprising:
- a catheter introducer having a forward end; and
a hemostasis device including an elongate flexible hollow shaft having an inflatable anchor balloon at a forward end thereof and an inflatable peripheral balloon adjacent said forward end of said flexible hollow shaft, said hemostasis device being arranged to be insertable into an artery via said catheter introducer.

21. Apparatus for hemostasis of an artery having a puncture after arterial catheterization, the apparatus being adapted for use with a catheter introducer having a forward end and comprising:
a hemostasis device including an elongate flexible hollow shaft having an inflatable anchor balloon at a forward end thereof and an inflatable peripheral balloon adjacent said forward end of said flexible hollow shaft, said hemostasis device being arranged to be insertable into an artery via said catheter introducer. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method for hemostasis of an artery having a puncture after arterial catheterization, said catheterization using a catheter introducer, the method comprising the steps of:
-
inserting into an artery a catheter introducer having a forward end;
following arterial catheterization and removal of a catheter from the catheter introducer, introducing into the artery via said catheter introducer, a hemostasis device including an elongate flexible hollow shaft having an inflatable anchor balloon at a forward end thereof and an inflatable peripheral balloon adjacent said forward end;
inflating the inflatable anchor balloon inside the artery, causing said inflatable anchor balloon to assume an inflated state;
retracting the hemostasis device relative to the catheter introducer, until said anchor balloon in said inflated state engages said forward end of said catheter introducer;
retracting said hemostasis device and said catheter introducer until said anchor balloon in said inflated state sealingly engages an inner wall surface of a wall of the artery about said catheter introducer;
thereafter retracting said catheter introducer such that the forward end thereof lies outside the wall of the artery, while said anchor balloon in said inflated state blocks blood flow from the artery;
inflating said peripheral balloon adjacent the forward end of the catheter introducer as it lies outside an outer surface of the wall of the artery, thereby causing the peripheral balloon to assume an inflated state;
deflating the inflatable anchor balloon;
thereafter, withdrawing said forward end of said flexible hollow shaft from said artery, while said peripheral balloon seals a region outside said artery and surrounding an aperture in said artery through which said forward end of said flexible shaft was withdrawn, allowing hemostasis to occur thereat; and
following hemostasis, deflating of said peripheral balloon and removal of said hemostasis device from the patient. - View Dependent Claims (42, 43)
