RADIAL ARTERY DEVICE
First Claim
1. A vessel pressure control device configured for selectively applying pressure to a radial artery, said device comprising:
- a sensor configured to sense one or more parameters associated with blood flow through a portion of said radial artery;
a pressure application element adapted to apply variable amounts of pressure to said portion of said radial artery; and
a controller configured to apply logic and generate a signal to control said pressure application element in response to said one or more measured parameters, said signal controlling said pressure application element to modify or maintain said applied pressure so that at least some blood flow is maintained through said radial artery portion in an amount sufficient to reduce or prevent radial artery occlusion, and so that said applied pressure is sufficient to prevent bleeding from said portion.

14. A device adapted for measuring blood flow through a portion of a radial artery, said device comprising:
-
a sensor adapted to sense one or more parameters associated with an amount of blood flow through said portion, said sensor is adapted to sense said one or more parameters at a depth of no more than about 10 mm; and an output interface electrically coupled to said sensor, said output interface configured to provide output according to one or more predetermined thresholds and/or ranges of said one or more parameters. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method of controlled closure of a portion of a radial artery comprising:
-
applying pressure to said radial artery portion in an amount to stop bleeding from said radial artery portion; and maintaining or adjusting said applied pressure, so that enough blood flows through said radial artery portion to prevent or reduce radial artery occlusion, while said stopped bleeding is maintained. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
