Abstract
A medical device configured to collect tissue from within a subject's body includes an elongate shaft having a proximal end, a distal end, and a distal region proximate the distal end. A plurality of bristles may be positioned on the distal region to form a brush. The distal region may be configured to deform upon activation to increase a cross-sectional dimension of the brush. The cross-sectional dimension of the brush may be the largest dimension of the brush in a direction transverse to a longitudinal axis of the shaft.

A medical device configured to collect tissue from within a body of a subject, comprising:
- an elongate shaft having a proximal end, a distal end, and a distal region proximate the distal end;
- and
- a plurality of bristles positioned on the distal region of the shaft to form a brush, wherein the distal region of the shaft is configured to deform upon activation to increase a cross-sectional dimension of the brush, wherein the cross-sectional dimension of the brush is a largest dimension of the brush in a direction transverse to a longitudinal axis of the shaft.
A method of collecting tissue from within a body of a subject, comprising:
- inserting a medical device into the body, the medical device including:
- an elongate shaft having a proximal end, a distal end, and a distal region proximate the distal end;
- and
- a plurality of bristles positioned on the distal region of the shaft to form a brush having a cross-sectional dimension of a first value, wherein the cross-sectional dimension of the brush is a largest dimension of the brush in a direction transverse to a longitudinal axis of the shaft;
- activating the medical device to deform the distal region of the shaft such that the cross-sectional dimension of the brush increases from the first value after the activation.
A medical device configured to collect tissue from within a body of a subject, comprising:
- a sheath having a lumen extending therethrough;
- an elongate shaft configured to be introduced into the body through the lumen, the shaft having a proximal end, a distal end, and a distal region proximate the distal end;
- a plurality of bristles positioned on the distal region of the shaft to form a brush having a cross-sectional dimension, wherein the cross-sectional dimension is a largest dimension of the brush in a direction transverse to a longitudinal axis of the shaft, and wherein the cross-sectional dimension is a first value when the brush is positioned within the lumen and a second value, greater than the first value, when the brush is positioned outside the lumen;
- and
- at least one articulating joint on the distal region of the shaft, wherein upon activation, the distal region of the shaft is configured to bend at the at least one articulating joint to increase the cross-sectional dimension of the brush from the second value before the activation to a third value after the activation.
