Embodiment Construction

[0029] The present disclosure may be further understood by reference to the following description and drawings, wherein like reference numerals refer to like elements. The present disclosure relates to biopsy devices. Exemplary embodiments of the present disclosure describe a biopsy device that includes an outer sheath through which an inner sampling needle is slidably received, through which the inner needle can be removed and inserted into a target as desired site to collect multiple tissue samples from the target site. A tissue sample can be collected from the inner needle by flushing it into a collection bottle connected to the handle housing of the device so that the inner needle can be reinserted into the target site to collect additional tissue samples. It should be noted that the terms "proximal" and "distal" are intended to mean a direction towards a user of the device (proximal end) as well as a direction away from a user of the device (distal end).

Abstract

A device for acquiring a tissue sample includes an outer sheath extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough; an inner needle extending longitudinally from a proximal end to a distal end and sized and shaped to be slidably received within the lumen of the outer sheath to be moved between an insertion configuration and a tissue collectingconfiguration; and a handle assembly connected to a proximal end of the outer sheath. The handle assembly includes a first port configured to be connected to a fluid flushing source and a second portconfigured to be connected to a collection element so that, when the inner needle is drawn proximally relative to the outer sheath to a sample collection configuration, the sample is flushable into the collection element.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 111,821, filed February 4, 2015, and U.S. Nonprovisional Application No. 15 / 021,077, filed February 1, 2016, which is adopted in its entirety Incorporated herein by reference. Background technique [0003] Needle biopsy procedures are commonly used for diagnosis and staging of disease. For example, a percutaneous biopsy needle can be introduced through an incision in the skin to a target tissue site. In certain clinical situations, it may be difficult to obtain a suitable sample with a single needle puncture to the target tissue site. The more cells or tissue obtained, the more likely the diagnosis will be confirmed. However, multiple insertions of the biopsy needle may increase the risk of infection and / or the risk of seeding unhealthy tissue within healthy tissue.
