Abstract
A system may include an expandable member, and a plurality of sensors disposed on an outer surface of the expandable member and circumferentially spaced apart from one another, wherein each of the plurality of sensors includes a first emitter configured to emit light of a first wavelength, and a detector configured to detect light, and a controller coupled to the plurality of sensors.
Claims21
1-20. (canceled)
A medical device, comprising:
- a shaft;
- and
- an assembly coupled to a distal end of the shaft, the assembly including a plurality of arms circumferentially spaced apart from one another about the distal end and a sensor coupled to each of the plurality of arms;
- wherein the plurality of arms are configured to move relative to the distal end between a first position and a second position;
- wherein, in the first position, the plurality of arms are in an undeployed configuration such that each of the plurality of arms lie substantially flush relative to the distal end, and in the second position, the plurality of arms are released to a deployed configuration such that each of the plurality of arms extends radially outwards relative to the distal end.
2 more elements
A medical device, comprising:
- a shaft having a distal end for deployment within a bodily lumen;
- and
- an assembly coupled to the distal end and including two or more arms each having a sensor, the two or more arms being configured to move relative to the distal end between a first position and a second position;
- wherein, the two or more arms are positioned substantially flush with the distal end in an undeployed configuration when in the first position, such that the sensor on each of the two or more arms is inoperable for emitting light and detecting light intensity;
- wherein, the two or more arms are positioned distally relative to the distal end in a deployed configuration when in the second position, such that the sensor on each of the two or more arms is operable to emit light and detect a light intensity from within the bodily lumen.
2 more elements
A medical device, comprising:
- a shaft;
- and
- an assembly coupled to a distal end of the shaft, and including a plurality of arms that are flexibly movable relative to the distal end;
- wherein, in a first position, the assembly is undeployed with the plurality of arms positioned laterally inwards towards the distal end such that a sensor on each of the plurality of arms faces inwards towards the distal end;
- and
- wherein, in a second position, the assembly is deployed with the plurality of arms positioned laterally outwards from the distal end such that the sensor on each of the plurality of arms faces outwards away from the distal end.
