Considering over 220,000 catheter ablations are performed each year in the U.S., this adds significantly to the cost of healthcare. Scientists have developed new materials that allow for therapeutic arrays and sensors designed to measure electrical activity, temperature, blood flow, and pressure to flex with the opening and closing of a balloon. The balloon is inserted into the upper regions of the heart where it can be expanded. Once in place, the cardiologist can perform an EP study and ablate areas causing the arrhythmias. Along with lower costs, the technolo...

Its main action is to anchor the clavicle. Its proximal attachment (origin) is the 1st rib and costal cartilage. The distal attachment (insertion) is the inferior surface of the mid-clavicle. Innervation is via a local nerve branch off the brachial plexus. The muscle is of clinical significance in that it is intentionally punctured when placing a subclavian central venous catheter. It also functions in protecting the underlying subclavian artery and vein from being punctured in displaced clavicle fractures.

But if the surgeon wants to use a device that heats the tissue non-invasively to create non-conducting lines in the atrium, that's not okay in the eyes of the law because it isn't labeled for that use specifically for use in the left atrium by the FDA, even though the FDA approved (one example) the device for medical use.You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adu...

To assure patients heard a consistent message and to help facilitate our visits with them, we decided to create a 9-minute video to supplement our discussions during our procedural consenting process. While our video was professionally produced (and the circles around my eyes disclose the time of day this was shot), no doubt a simpler video using a hand-held HD video camera and iMovie software on a MAC could provide similar results at lower cost.In general, I think our patients have appreciated that they can view the video online at home or here in our office as often as desired. We also have burned co...

They chronicled the procedure largely from a script that Oza had signed off on a day earlier. The procedure uses radio frequencies to scar parts of the heart. The scars block signals sent from a quartet of veins in the left atrium, signals that cause the heart to go haywire. The entire procedure is done using a catheter inserted into a patient’s groin while the patient is anesthetized.Given several hours of time to fill and only a page and a half of script, Candy Bowen, the Web producer, sprinkled in descriptions about...

William Ganz, Catheter Inventor, Dies at 90 By DOUGLAS MARTIN Published: November 13, 2009 Dr. William Ganz, a cardiologist and medical inventor who helped develop a revolutionary catheter to measure blood flow and heart functions, died Tuesday in Los Angeles. He was 90. … The catheter, which is used more than one million times a year in the United States, is known as the Swan-Ganz because Dr. Ganz created it with Dr. Jeremy Swan at Cedars-Sinai Medical Center. It is inserted through a vein in the neck, shoulder or groin and fed into the right side of the heart. A balloon at the device’s tip allows it to be carried along by blood flow. I was fortunate enough to get a chance to ‘float a Swan’ a few times as a resident, and never since. Are the...

Heart block was induced each and every time from each and every angle they tried to ablate. Dr. A and his team were left with little choice but to ablate Stellan's AV node in order to get rid of his accessory pathway. But before they did, one of Dr. A's colleagues threw out a wild idea."Let's try to go through his aorta."Not in the plan. Not even in the possible or hypothetical plans. Not considered safe or feasible or wise on a 10 kilo baby. But with few options left before destroying Stellan's node, they decided to risk it.To be honest, I'm glad I didn't know about it at the time.So from his groin, they threaded the catheter up into his aorta, down into...

Like many of the medieval medical tools science has developed to help us cope with our symptoms. However, we tend to wait until far past the point they are needed to use them. At that point we wonder why we waited so bleeding long! For example, we put off a cane until we hardly can get out of the house anymore, then find that by using one we can actually walk around the block again. We scoff at the idea of a scooter, then realize how many kid’s soccer games we’ve missed or how many fun adventures we’ve said “no” to only after we’ve acquiesced. Using a catheter is another one of “those” topics How many UTIs does it take, how many fevers spiking and setting of...

Some urologists do not use it at all, some use it even before surgery, and some after the catheter comes out.It is unclear how long patients need to wait to have intercourse after their catheters are removed. Some say 6 weeks, some 4, and some less. I used to say 2 weeks until 1 man had a painful time after 2 weeks. Since then I have patients wait at least 3 weeks.Ive had several patients have intercourse in less time than that, with the record being 9 days.
