Technical Examples

A device and method for the obtaining a tissue biopsy and the delivery of a material to provide hemostatis, therapeutic agents or marker material is described that can be used in conjunction with either an aspiration biopsy or a cutting needle biopsy device. The device has an application chamber through which the biopsy mechanism, either a cutting needle device or aspiration needle, passes through. The mechanism for an aspiration biopsy has a biopsy cannula of constant cross section over its entire length connected to an aspiration and collecting chamber and at least one application channel of constant or varying cross section connected to a dispensing chamber integrally connected with the aspiration chamber. The cutting biopsy mechanism has a mechanical or electromechanical mechanism to rapidly fire a stylet with a biopsy trough into the intended tissue and then fire a biopsy cannula over the stylet to sever and retain tissue that has protruded into the biopsy trough. At least one application channel is formed by a tube centrically slipped over the biopsy cannula wall. To enable the collection of tissue specimens, the distal segment of the application channel forms a close fitting and concentric sheath around the biopsy cannula. The versatility of the invention permits its use in many applications, including, for example, liver biopsies, breast biopsies, laparoscopic surgery, and lymphadenectomy procedures.
