Abstract: A biopsy device includes a cylindrical hollow stylet having a proximal end, a distal end, and a uniform wall thickness. The proximal end and the distal end are disposed on the longitudinal axis. A longitudinal recess forms a sample chamber and is positioned adjacent the distal end of the cylindrical hollow stylet. A longitudinal insert has a longitudinal length, a distal terminal end, and an elongate channel. The longitudinal insert is positioned within the cylindrical hollow stylet with the distal terminal end proximal to the longitudinal recess. The longitudinal insert is immovably connected to the cylindrical hollow stylet. The elongate channel is configured to maintain a fluid passageway through the cylindrical hollow stylet from the proximal end to the longitudinal recess.

Abstract: A high aspect ratio biopsy needle achieves reliable performance with large solid sample size by means of a variety of features and combinations thereof, including support to prevent bending, reinforcement of the needle, and cutting edges arranged to resist deformation.

Abstract: An implantable vessel filter having an integrated sensing capability for monitoring the condition of the vessel filter. In one variation, the vessel filter comprises a plurality of legs that would themselves perform as a sensor device for detecting distention, which would indicate the presence of a clot or thrombus therein. A passive electrical circuit may be implemented on the vessel filter to receive electromagnetic energy and transmit signals indicative of the condition of the implanted vessel filter. In another variation, a miniaturized sensor is adapted for measuring the strain and/or other physical parameters of the filter legs.
