Abstract
A system for monitoring the flow of blood within an endoluminal passage is provided comprising a medical device and a sensor. The medical device is implantable within the endoluminal passage and includes a shaft and an expandable segment coupled to the shaft. The expandable segment is movable between a first state and a second state. Movement of the expandable segment is responsive to a change in the fluid pressure external to the expandable segment. The sensor is positioned on the medical device and is adapted to collect information associated with the state of the expandable segment.
Claims20
A system for monitoring the flow of blood within an endoluminal passage, comprising:
- a medical device implantable within an endoluminal passage, the medical device comprising a shaft and an expandable segment coupled to the shaft, the expandable segment being movable between a first state and a second state, wherein movement of the expandable segment is responsive to a change in fluid pressure external to the expandable segment;
- and
- a sensor positioned on the medical device configured to collect information associated with the state of the expandable segment.
A system for monitoring the flow of blood within an endoluminal passage, comprising:
- a medical device implantable within an endoluminal passage, the medical device comprising a shaft and a plurality of expandable segments coupled to the shaft, wherein the plurality of expandable segments are arranged linearly along the shaft and each of the plurality of expandable segments being movable between a first state and a second state, wherein movement of the expandable segment is responsive to a change in fluid pressure external to the expandable segment;
- and
- a plurality of sensors positioned on the medical device, the plurality of sensors configured to collect information associated with the states of the plurality of expandable segments.
A method of determining a characteristic of the flow of blood within an endoluminal passage, comprising:
- implanting a medical device within an endoluminal passage, the medical device comprising a shaft, an expandable segment coupled to the shaft, and a sensor positioned on the medical device, the expandable segment being movable between an expanded state and a compressed state, wherein movement of the expandable segment is responsive to a change in the flow of blood within the endoluminal passage over the expandable segment;
- transmitting a signal generated by the sensor responsive to the flow of blood in the endoluminal passage over the medical device.
