Abstract: A percutaneous catheter introducer (PCI) is disclosed having a transparent housing, a valve seal disposed within the housing, a rotatable suture ring including a tab, and a sheath extending through the suture ring and into the housing. The transparent housing allows for detection of emboli formation inside the percutaneous catheter introducer. The rotatable suture ring permits versatility of movement when sewing the PCI device to the patient.
Abstract: A catheter introducer valve assembly of a catheter introducer leading to a blood vessel of a patient for positioning at least one catheter tube through the catheter introducer and its sheath to a blood vessel of a patient. The valve assembly unit has first and second valves, the first valve being for preventing or minimizing the flow of blood from the valve assembly unit when the catheter tube is absent from the catheter introducer and the second valve being for preventing or minimizing the flow of blood when the catheter tube is present in the catheter introducer. The first valve, which is made of a flexible, resilient material, is shaped as a disk having a valve slit, such a duckbill valve, positioned diametrically across the passage of the valve assembly body. The rim surface of the valve disk has a slightly smaller diameter than the diameter of the positioning area of the inner surface of the valve assembly body where the valve disk is located so that a cylindrical space is formed therebetween.
Abstract: A self-sealing percutaneous tube (e.g. catheter) introducer having a sealing mechanism to prevent blood or fluid leakage that includes spaced sealing gaskets adapted to surround the tube, a distal sealing element being planar and having a slit whereas the proximal sealing element being conical and having an annular opening at its distal and small end, the introducer optionally including a side arm flushing member and/or a female luer lock connection at its proximal end.
