Patent ID: 8285366

Claim:
An untethered device comprising: a local bypass configured to function in one or more blood vessel or lymph vessel of a subject; one or more first energy source configured to function in, or proximal to, a lumen of the local bypass and to provide energy configured to elicit one or more image responses associated with the local bypass lumen; one or more sensors configured to function in, or proximal to, the local bypass lumen and to capture the one or more image responses; 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, or proximal to, the local bypass lumen at least partially based on the captured one or more image responses; one or more closable openings included on each end of the local bypass, the one or more closable openings configured to modulate fluid flow to and from the local bypass lumen at least partially based on the one or more image responses captured by the one or more sensors; and one or more second energy source responsive to the control circuitry, and configured to provide ablation energy to a target area in the local bypass lumen during the expected transit time of the one or more targets through the target area.
