摘要： This disclosure includes intraluminal tubes comprising: an elongated tube (e.g., having a proximal portion, a distal portion configured to be disposed inside of an internal cavity of a patient, and a sidewall defining a lumen extending from the proximal portion to the distal portion, the distal portion defining one or more openings in fluid communication with the lumen) and a plurality of deployable tines, each coupled to the tube and disposed outside the sidewall of the distal portion, where each tine is movable from a collapsed state to a deployed state in which a portion of the tine extends laterally away from the distal portion of the tube. In some of the present intraluminal tubes, the sidewall of the distal portion defines a plurality of longitudinal grooves, and each tine is disposed in a different one of the grooves when the tines are in the collapsed state.
