    摘要: A method, technique and system is disclosed for the delivery of therapeutic agents and/or into the bulk brain tissues and other parts, tissues and organs of the body, including vasculature. A novel form of coaxial catheter provides a means for implanting an outer tube into the brain, then inserting an inner tube into the outer tube and aligning them such that port holes on both of the tubes will overlap and permit a flux of the therapeutic agent to flow into the brain in such a way as to minimize the effects of trapped air, virtually eliminate backflow of the agent, and avoid the potential for additional damage to the brain since only one surgical placement of the outer tube is needed. Similarly, the method, technique system may be utilized to remove fluids or other medium from the brain, tissues, and organs to minimize the effects of escaped air or negative pressure.

    摘要: A method is disclosed for the delivery of therapeutic agents into tissues, blood vessels, and body ducts of the human body. A novel catheter enables controlled directing of emitted drug delivery to assist control of drug dwell time in targeted areas. One coaxial catheter embodiment provides capability for locating an outer lumen of the system into the target region, with localization of said outer lumen carried out by use of appropriate medical imaging modalities. In one embodiment, an inner lumen of the catheter means is primed with the agent to be delivered, and recirculated flow of the agent through pluralities of appropriately positioned port holes on the two lumens then occurs via one or more active and/or passive flow driving and guiding techniques intrinsic to the design of the coaxial catheter system. Another coaxial catheter embodiment carries and emits agent in an outer cannula and recaptures agent plus liquid or fluids in the body (such as blood, bile, serum, stable (non-flowing) liquid or kinetic liquid) in an inner cannula.

    摘要: A tool and method of positioning and delivering medical devices and therapeutics within the pericardial space, as well as other body part or space. A needle is inserted into the chest through a sub-xiphoid puncture, and the pressure within the needle is monitored manometrically or otherwise sensed as the needle is advanced towards the pericardial space. By reading the pressure within the needle while it is advanced, the clinician is able to know that he or she is avoiding insertion of it into organs or spaces not intended to be the target location. In addition the retractable sharp edge allows the operator to access the space and cut tissue but do so safely by retracting the sharp edge.
