Patent ID: 6986748

Claim:
An endoluminal device for taking a plurality of tissue samples, comprising: a proximal actuation mechanism attached to a distal sampler by an elongate member, wherein the distal sampler includes: a distal inner portion having a longitudinal axis and defining a plurality of chambers, each configured to receive a tissue sample; and a distal outer portion defining a cutting mechanism opening and a cutting edge adjacent the cutting mechanism opening, the distal outer portion being axially and rotatably movable relative to the distal inner portion, wherein the cutting mechanism opening faces a direction transverse to the longitudinal axis of the distal inner portion, wherein the distal outer portion is configured so that, when the cutting mechanism opening aligns with one of the plurality of chambers, the distal outer portion covers at least one of the remaining chambers, and wherein actuation of the proximal actuation mechanism causes the distal outer portion to move axially and rotatably relative to the distal inner portion.
