Seldinger Set
The Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organ (anatomy), organs. It is eponym, named after Dr. Sven Ivar Seldinger (1921–1998), a Sweden, Swedish radiology, radiologist who introduced the procedure in 1953. Uses The Seldinger technique is used for angiography, insertion of chest drains and central venous catheters, insertion of percutaneous endoscopic gastrostomy, PEG tubes using the push technique, insertion of the leads for an artificial pacemaker or implantable cardioverter-defibrillator, and numerous other interventional medical procedures. Complications The initial puncture is with a sharp instrument, and this may lead to hemorrhage or perforation of the organ in question. Infection is a possible complication, and hence asepsis is practiced during most Seldinger procedures. Loss of the guidewire into the cavity or blood vessel is a significant and generally preventable ...

Charles Dotter
Charles Theodore Dotter (14 June 1920 – 15 February 1985) was a pioneering US Blood vessel, vascular radiologist who is credited with developing interventional radiology. Dotter, with his trainee Melvin Judkins, Dr Melvin P. Judkins, described angioplasty in 1964. Dotter received a bachelor of arts degree in 1941 from Duke University. He went to medical school at Cornell, where he met his future wife, Pamela Beattie, a head nurse at New York Hospital. They married in 1944. He completed his internship at the United States Naval Hospital in New York State, and his residency at New York Hospital. Dotter invented angioplasty and the catheter-delivered stent, which were first used to treat peripheral arterial disease. It was Dotter who, in 1950, developed an automatic X-Ray Roll-Film magazine capable of producing images at the rate of 2 per second. On January 16, 1964, at Oregon Health and Science University Dotter percutaneously dilated a tight, localized stenosis of the superficia ...

Trochar
A trocar (or trochar) is a medical device, medical or veterinary medicine, veterinary device that is made up of an wikt:awl, awl (which may be a metal or plastic sharpened or non-bladed tip), a cannula (essentially a hollow tube), and a seal. Trocars are placed through the abdomen during laparoscopic surgery. The trocar functions as a portal for the subsequent placement of other instruments, such as graspers, scissors, staplers, etc. Trocars also allow the escape of gas or fluid from organs within the body. Etymology The word ''trocar'', less commonly ''trochar'', comes from French language, French ''trocart'', ''trois-quarts'' (three-fourths), from ''trois'' 'three' and ''carre'' 'side, face of an instrument', first recorded in the ''Dictionnaire des Arts et des Sciences'', 1694, by Thomas Corneille, younger brother of Pierre Corneille. History Originally, doctors used trocars to relieve pressure build-up of fluids (edema) or gases (bloating). Patents for trocars appeared early ...

Catheter Ablation
Catheter ablation is a procedure used to remove or terminate a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome. If not controlled, such arrhythmias increase the risk of ventricular fibrillation and sudden cardiac arrest. The ablation procedure can be classified by energy source: radiofrequency ablation and cryoablation. Medical uses Catheter ablation may be recommended for a recurrent or persistent Heart arrhythmia, arrhythmia resulting in symptoms or other dysfunction. Typically, catheter ablation is used only when pharmacologic treatment has been ineffective. Effectiveness Catheter ablation of most arrhythmias has a high success rate. Success rates for WPW syndrome have been as high as 95% For SVT, single procedure success is 91% to 96% (95% CI) and multiple procedure success is 92% to 97% (95% CI). For atrial flutter, single procedure succ ...
