Abstract:
1. An untethered device comprising: one or more first energy source configured to function in, or proximal to, one or more blood vessel or lymph vessel of a subject and to provide energy configured to elicit one or more image responses associated with the one or more blood vessel or lymph vessel; one or more sensors configured to function in, or proximal to, the one or more blood vessel or lymph vessel and to capture the one or more image responses, and wherein the one or more sensors are configured to orient to the one or more first energy sources; control circuitry coupled to the one or more sensors and responsive to at least partially identify one or more targets during an expected transit time of the one or more targets through a detection area in the one or more blood vessel or lymph vessel at least partially based on the captured one or more image responses; one or more inserts configured to be disposed in the one or more blood vessel or lymph vessel and including a lumen extending therethrough having a lateral dimension that decreases at a choke point, the choke point configured to at least slow the one or more targets based at least partially on a size thereof as the one or more targets attempt to flow through the lumen; and one or more second energy source configured to provide ablation energy to the one or more targets when the one or more targets are at least slowed by the choke point of the lumen responsive to the control circuitry at least partially identifying the one or more targets.
