Claims
- 1. A system to detect sealing of a puncture in a blood vessel wall by a seal inside the blood vessel, comprising:an introducer assembly having a distal end and a proximal end and a fluid path between the distal end and the proximal end, the introducer assembly arranged such that the distal end of the introducer assembly is in tissue outside a puncture in a blood vessel wall; and an assembly to observe a characteristic of blood at the proximal end of the introducer assembly to determine whether the puncture is sealed by said seal inside the blood vessel.
- 2. A system as set forth in claim 1, further comprising:an output port, in communication with said fluid path, to visually observe a flow of blood from said fluid path.
- 3. A system as set forth in claim 1, further comprising:a pressure sensor, connected to the proximal end of the introducer assembly; and a display to display an indication of blood pressure measured by the pressure sensor.
- 4. A system as set forth in claim 1, further comprising:a pressure sensor, connected to the proximal end of the introducer assembly; and a display to display a numerical indication of blood pressure measured by the pressure sensor.
- 5. A system as set forth in claim 1, further comprising:a pressure sensor connected to the proximal end of the introducer assembly; and a display, which receives signals from the pressure sensor, to display a blood pressure waveform.
