AI Technical Summary

Benefits of technology

The vacuum-assisted system provides larger and more assured tissue samples, improving diagnostic accuracy and clinical efficiency, especially for smaller lesions and calcifications, while reducing device weight and enhancing ultrasound visibility.

Problems solved by technology

The size and weight of the device generally hinder the ability of the clinician to position the biopsy device in the desired location.

Embodiment Construction

[0018]These and other features and advantages of this invention are described in, or are apparent from, the following detailed description of various example aspects.

[0019]FIGS. 2A-2B are diagrams illustrating a vacuum-assisted biopsy device, according to various aspects of the current invention. In FIG. 2A, the vacuum-assisted biopsy device 100 includes a stylet tip 110 that, during operation, penetrates the skin / tissue of a patient and is inserted through the skin to remove one or more tissue samples from the patient, the tissue samples being deposited in the notch 150 of the stylet tip 110. According to various aspects, the stylet tip 110 may be connected to a vacuum pump 130 via a vacuum line 120 and a housing 160, the vacuum pump 130 including a valve 140. The housing 160 may include, in the case of a spring-loaded biopsy device, a valve mechanism and / or the firing mechanism to fire a cannula over the stylet tip 110 to sever tissue samples. According to various aspects, the hou...

Abstract

Methods and devices for providing a biopsy device with a modified handle and stylet that provides a vacuum to be delivered to the targeted tissue for removal. The vacuum may draw the tissue into the notch where the tissue may then be severed via the cannula. Alternatively, the tissue may be drawn into to the notch after being severed via the stylet and / or cannula. The vacuum may be used to bring a larger amount of tissue into the notch than would otherwise be brought in the notch if no vacuum was used, providing a larger sample through the same size access point.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Divisional of U.S. patent application Ser. No. 13 / 490,075, filed on Jun. 6, 2012. The disclosure of the priority application is incorporated in its entirety herein by reference.BACKGROUND OF THE INVENTION1. Field of Invention[0002]Aspects of the present invention relate to methods and devices for performing vacuum assisted biopsies. More particularly, aspects of the current invention relate to methods and devices for performing vacuum assisted spring-loaded biopsies.2. Description of Related Art[0003]A variety of biopsy devices having sampling needles as part of their structure are available in the medical field. Typical biopsy devices include those that are designed to obtain samples from hard tissues, such as bone, and those that are designed for sampling of softer tissues. Soft tissue biopsy devices can include a structure whereby a sampling needle resides within an outer cannula and moves relative thereto during ...
