Embodiment Construction

[0070] The energy assisted system of the present invention may be applied in connection with a variety of medical devices and / or procedures. However, the system of the present invention is primarily described herein in connection with a representative embodiment of an energy-assisted "needle." FIG. 1, for example, illustrates a block diagram of an energy-assisted needle system of the present invention for illustrating the general function of various embodiments of the energy-assisted needle system of the present invention. As used herein, the term "needle" refers to a relatively elongated device that can be used for penetration, including devices having a channel or passageway for the parenteral introduction of material into or removal of material from the body. In common language, needles tend to be sharp or rigid while catheters are non-piercing and generally soft and pliable. With energy assist, the distinction is blurred because soft materials, such as those used for cath...

Abstract

A device for penetrating tissue and removing a biological sample includes a biological sampling element to remove a biological sample. The biological sampling element includes a passage therethrough. The device further includes a penetrator 101 positioned within the passage. The penetrator 101 is energized in a repetitive manner to assist in penetrating tissue. The biological sample element can be adapted to remove a tissue sample or a biological fluid sample (for example, blood). A device for penetrating tissue and positioning a tissue resident conduit (for example, a catheter 400), includes a tissue resident conduit (for example, a catheter 400) including a passage therethrough; and a penetrator in operative connection with the catheter 400. A device for inserting a tissue resident conduit includes at least one component that is energized during penetration to assist in penetrating tissue.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 60 / 552,660, filed March 11, 2004, the disclosure of which is hereby incorporated by reference. Background of the invention [0003] The present invention relates generally to energy assisted devices, systems and methods, and more particularly to energy assisted medical needles, to medical needle systems and methods of energy assisted insertion of needles into tissue. [0004] A biopsy is a medical procedure in which a piece of tissue is taken from a patient for a pathologist to make or establish a diagnosis with high confidence. The reliability of the diagnosis depends on obtaining a sample of suspicious tissue of sufficient quality to make a diagnosis. [0005] There are three types of biopsies, including surgical biopsy, endoscopic biopsy, and needle biopsy. In order to cause as little pain and distress to the patient as possible, the...
