Abstract

Devices and methods are provided for performing procedure on tissue with flow monitoring using flow sensors. The devices include an elongated member, and at least one flow sensor disposed on the elongated member. The flow sensor includes at least one temperature sensor and at least one heating element having a cavity. At least a portion of the at least one temperature sensor is housed in the cavity. A temperature measurement of the temperature sensor provides an indication of the flow rate of a fluid proximate to the flow sensor.

Claims27

Dependent claims

An apparatus for displaying representations of parameters of an inflatable body and/or expandable body disposed proximate to a portion of a tissue, the inflatable body and/or expandable body comprising a plurality of sensors coupled to at least a portion of the inflatable body and/or expandable body, the apparatus comprising:

a user interface;
at least one memory to store processor-executable instructions;
and
at least one processing unit communicatively coupled to the at least one memory, wherein, upon execution of the processor-executable instructions, the at least one processing unit:
controls the user interface to display at least one representation of the parameters, the at least one representation comprising:
(A) a first representation of a state of the inflatable body and/or expandable body, the first representation comprising:
(i) a first form indicator to indicate that the inflatable body and/or expandable body is in an inflated and/or an expanded state;
or
(ii) a second form indicator to indicate that the inflatable body and/or expandable body is in a deflated and/or a collapsed state;
and
(B) a second representation of a state of at least one sensor of the plurality of sensors, the second representation comprising:
(i) a first activation indicator to indicate that the at least one sensor of the plurality of sensors measures a signal below a threshold value;
or
(ii) a second activation indicator to indicate that the at least one sensor of the plurality of sensors measures a signal above or about equal to the threshold value,
wherein the second representation is indicative of a magnitude of an instantaneous velocity.
