SENSORS FOR CATHETER PUMPS |
| 摘要 |
Sensors for catheter pumps are disclosed herein. The catheter pump can include a catheter assembly comprising a catheter and a cannula coupled to a distal portion of the catheter. The cannula can have a proximal port for permitting the flow of blood therethrough. The catheter assembly can include a sensor to be disposed near the proximal port. A processing unit can be programmed to process a signal detected by the sensor. The processing unit can comprise a computer-readable set of rules to evaluate the signal to determine a position of the cannula relative to an aortic valve of a patient. |

1. A catheter assembly comprising:
a catheter body; a cannula coupled to a distal portion of the catheter, the cannula having a proximal port and a distal port for permitting the flow of blood therethrough; and a sensor assembly, wherein the sensor assembly comprises at least one of: (a) a proximal sensor coupled with the catheter body and having a distal portion near the proximal port, and (b) a distal sensor coupled with the cannula and having a distal portion near the distal port. |
