    摘要: An atherectomy apparatus and method is disclosed for the purpose of surgical excision of atheromas which typically consist of plaque deposits that cause narrowing (stenosis) of an artery. The apparatus, called a pullback atherectomy catheter, cuts and collects obstructive material into a collection chamber as the catheter is pulled back through obstructive material within a human vessel such as an artery.

    摘要: A catheter-based/intravascular fluid injection system with application to renal denervation includes a multiplicity of needles which expand open around a central axis to engage the wall of a blood vessel, or the wall of the left atrium, allowing the injection of a cytotoxic and/or neurotoxic solution for ablating conducting tissue, or nerve fibers around the ostium of the pulmonary vein, or circumferentially in or just beyond the outer layer of the renal artery. The expandable delivery system includes expandable components that facilitate positioning of a multiplicity of injection needles against the inside wall of a blood vessel from where they can be advanced. The system also includes means to limit and/or adjust the depth of penetration of the ablative fluid into the tissue of the wall of the targeted blood vessel.

    摘要: A Finger Actuated Medication Infusion System (FAMIS) for delivering a dosage of medication into a living body. The FAMIS is fully mechanical and comprises a reservoir, a pump and connecting catheters. The reservoir includes a sealed bellows portion which contains a pressurant and exerts a substantially constant pressure on the medication in the reservoir, regardless of the amount of medication therein. The pump includes a bellows assembly disposed within an equalizing pressure chamber, and will deliver medication through the bellows assembly at a predetermined flow rate independent of ambient temperature, ambient pressure or the amount of medication remaining in the reservoir. The FAMIS design also provides safeguards against inadvertant overdosing, transmission of bacteria into the body and prevents gas bubbles within the reservoir from impeding the flow of medication through an outlet flow restrictor which forms part of the FAMIS pump.

    摘要: The invention is a system for reducing blood loss when placing a guiding catheter into an artery of a human subject. The system consists of a guiding catheter, a sealing means to be placed on the guiding catheter's proximal end and a guide wire that can be placed through both the guiding catheter and the sealing means to assist in placing the guiding catheter into a specific artery. The sealing means is typically a cap consisting of a male Luer lock fitting that includes a hemostasis valve that is designed to seal around the guide wire. The cap can be a separate component or it can be joined to the guiding catheter's proximal end by means of a flexible hinge. After the guiding catheter has been placed at a desired location in the arterial system, the cap and guide wire can be removed and a "Y" adaptor would then be placed onto the guiding catheter's proximal end. If desired the flexible hinge could also be removed from the guiding catheter.

    摘要: Disclosed is an Expandable Pullback Atherectomy Catheter (EPAC) comprising a distal tip portion capable of assuming two diameters. The distal tip portion includes an expandable cutting means and an expandable tissue collecting means. The catheter is guided in an artery to the stenosis and the distal tip is urged past the stenosis while being maintained in a compressed state by a sheathing catheter. The sheathing catheter is withdrawn allowing the cutting means and collecting means to expand. The stenotic tissue is removed by pulling the distal tip back in a retrograde direction while the cut tissue is captured in the collecting means. Additional structural details are provided to prevent injury to the inner wall of an artery and to avoid total obstruction of the artery during the antherectomy procedure.
