Chest X-ray showing an implanted port. A port is more correctly known as a "totally implantable venous access device". They are also commonly referred to as a Portacath or Chemo port. Brand names include Eco Port, Clip-a-Port, SmartPort, Microport, Bardport, PowerPort, Passport, Port-a-Cath, Infuse-a-Port, Medi-Port, and Bioflo.
C. R. Bard, Inc. was founded in New York City by Charles R. Bard in 1907. Bard's first business involved importing Gomenol, which was used to treat urinary discomfort. [6] The company formally incorporated in 1923, and three years later, in 1926, Charles R. Bard sold the company to John F. Willits and Edson L. Outwin for $18,000.
A comparative study among patients implanted with different models of artificial urinary sphincter and achieved social continence showed no difference between two groups in regards of urodynamic tests, such as flow rate, urethral pressure, etc. [2] A randomised controlled trial found that the artificial urinary sphincter was non-inferior to the ...
Surgically implanted infusion ports are placed below the clavicle (infraclavicular fossa), with the catheter threaded into the heart (right atrium) through a large vein. Once implanted, the port is accessed via a "gripper" non-coring Huber-tipped needle (PowerLoc is one brand, common sizes are 0.75 and 1 inch (19 and 25 mm) length; 19 and 20 gauge.
A separate actuator on the piping releases pressure in the line if it crosses a threshold. This releases the pressure on the back of the seal, causing the valve to open. The essential parts of a PORV are a pilot valve (or control pilot), a main valve, a pilot tube, the dome, a disc or piston, and a seat. The volume above the piston is called ...
Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as for chemotherapy.Similar to the Hickman line, the tip of the catheter is in the superior vena cava, and the catheter is tunneled under the skin to an incision on the chest wall, where the distal end of the catheter exits the body.
An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease). Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.
The devices are implanted without open heart surgery. The valve delivery system is inserted in the body, the valve is positioned and then implanted inside the diseased aortic valve, and then the delivery system is removed. The catheter-based delivery system can be inserted into the body from one of several sites. [14]
