TARGETABLE BIOPSY NEEDLE SET AND METHOD OF USING SAME

摘要

A biopsy needle set includes an introducer cannula having an elongate tubular body defining a lumen extending from an open proximal end to an open distal end. The introducer cannula also includes a lateral opening through a distal segment of the elongate tubular body that is in fluid communication with the lumen. The biopsy needle set also includes a biopsy needle configured to be telescopically received within the lumen of the introducer cannula. The biopsy needle includes a preformed curve causing a distal tip of the biopsy needle to point in a direction that is offset from a longitudinal direction of the introducer cannula. The biopsy needle set includes a first extended configuration in which the distal tip is advanced through the lateral opening and a second extended configuration in which the distal tip is advanced through the open distal end.

1. A biopsy needle set, comprising:
an introducer cannula having an elongate tubular body defining a lumen extending from an open proximal end to an open distal end, wherein the introducer cannula also includes a lateral opening through a distal segment of the elongate tubular body that is in fluid communication with the lumen; and a biopsy needle configured to be telescopically received within the lumen of the introducer cannula and including a preformed curve, wherein the preformed curve causes a distal tip of the biopsy needle to point in a direction that is offset from a longitudinal direction of the introducer cannula; wherein the biopsy needle set includes a first extended configuration in which the distal tip of the biopsy needle is advanced through the lateral opening of the introducer cannula and a second extended configuration in which the distal tip of the biopsy needle is advanced through the open distal end of the introducer cannula.
