Abstract
An instrument for removing a tissue sample from a subject comprises a plurality of tissue sampling devices having respective chambers, the tissue sampling devices being radially disposed along a length of the instrument such that upon insertion of the instrument into the subject one or more samples are extracted and isolated in the respective chambers of the sampling devices at the site at which removal occurs.
Claims24
A method of extracting multiple tissue samples from a subject, comprising
- inserting into a volume of a tissue an instrument comprising a sharp distal end and a plurality of controllable tissue sampling devices each of said devices being located in a different position in an array along a longitudinal axis of a housing and a plurality of isolated chambers, each of said sampling devices comprising a corresponding one of said isolated chambers, the volume of each of said isolated chambers being less than 1.2 cubic millimeters;
- actuating at least one of said a sampling devices by a deployment signal, said signal being selected from the group consisting of an electrical, optical, pneumatic, hydraulic, RF-transmitted, inductive, magnetic, thermal or sonic signal, said signal causing an opening of said chamber;
- removing tissue samples from anatomical locations at varying depths within said tissue;
- and
- sealing said chamber.

A method of extracting multiple tissue samples from a subject, the method comprising:
- inserting into a volume of a tissue an instrument comprising a sharp distal end, a plurality of controllable tissue sampling devices each of said devices being located in a different position in an array along a longitudinal axis of a housing, and a plurality of isolated chambers each of said sampling devices comprising a corresponding one of said isolated chambers, the volume of said isolated chamber being less than 1.2 cubic millimeters;
- heating the plurality of sampling devices, heating causing actuation of a mechanical portion of the plurality of sampling devices, such that a mechanical portion of the sampling devices collects samples from varying depths within said tissue and retains the samples;
- depositing the samples into said isolated chambers;
- and
- removing the instrument from the subject.
