Claim Text:
1. A device for needle biopsy comprising: a delivery handle system having an adjustable length, a longitudinal axis defining a lumen extending therethrough, and comprising a proximal handle member, a middle handle member and a distal handle member, the proximal handle member being slideably disposed over at least a portion of the middle handle member, the middle handle member being slideably disposed over at least a portion of the distal handle member, the proximal handle member comprising an inner hub housing component comprising an internally cylindrical shape configured to interchangeably receive a needle subassembly configured for inserting into and withdrawing from the proximal handle member; the needle subassembly comprising a needle having a proximal end portion and a distal end portion, a needle luer coupled to the proximal end portion of the needle, and a needle hub coupled to the proximal end portion of the needle, the needle hub configured for coupling with the inner hub housing component of the proximal handle member; and the needle subassembly further comprising a needle protector subassembly configured for coupling to the distal end portion of the needle, the needle protector subassembly comprising a needle protection hub having a lumen extending therethrough configured for receiving the distal end portion of the needle, a deformable O-ring axially disposed within the lumen of the needle protection hub, and a tubular sheath defining a lumen and extending from a distal end of the needle protection hub, the lumen of the tubular sheath in communication with the lumen of the needle protection hub for receiving the needle when inserted into the needle protection hub; wherein the lumen extending through the delivery handle system comprises: the device further comprising an inner handle member disposed within an inner portion of the middle handle member, the inner handle member coupled to a proximal portion of the catheter sheath and a distal portion of the outer hypotube, such that the catheter sheath is distally extended into the distal handle member when the middle handle member is distally advanced over the distal handle member.
