    Abstract: A medical delivery device suitable for insertion into a lumen of a patient, the medical device (100, 200) comprising a capsule (110, 120, 210, 220) sized to be inserted into the lumen, the capsule comprising a base member, and an actuation mechanism comprising an actuation member (150, 250, 350) configured for movement relative to the base member along an axis, and an energy source (140, 240, 340) associated with the actuation member for powering the actuation member to move relative to the base member along the axis. The base member and the actuation member define a latch assembly comprising: a) a dissolvable firing member (160, 260, 360), the dissolvable firing member being at least partially dissolvable when subjected to a biological fluid, b) a retainer portion (113, 213, 313) comprised by one of the base member and the actuation member, and c) a movable latch (152, 252, 352) configured for lateral movement relative to the axis, the movable latch defining a first surface with a blocking portion (153, 253, 353), and a second surface (152a, 252a, 352a) configured for interacting with the dissolvable firing member (160, 260, 360). In a pre-firing configuration, the blocking portion (153, 253, 353) of the movable latch engages the retainer portion (113, 213, 313) in a latching engagement, and the second surface (152a, 252a, 352a) of the movable latch interacts with the dissolvable firing member to restrict lateral movement of the movable latch thereby preventing release of the latching engagement. In a firing configuration where the dissolvable firing member (160, 260) has become at least partially dissolved, the movable latch is allowed to move laterally thereby releasing the latching engagement.

    Abstract: 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.
