• Vascular
  • Added Smith, "There are approximately 20 million patients with peripheral vascular disease who could benefit from this multi-purpose approach to catheter design, and we are excited to bring this innovative peripheral access product to market. (aol.com)
  • While OTW Catheters may still be useful in highly tortuous vascular pathways, they sacrifice deflation time and pushability. (wikipedia.org)
  • Angioplasty has come to include all manner of vascular interventions that are typically performed percutaneously. (wikipedia.org)
  • Angioplasty requires an access vessel, typically the femoral or radial artery or femoral vein to permit access to the vascular system for the wires and catheters used. (wikipedia.org)
  • Hematoma or pseudoaneurysm formation at the access site Radiation Injuries Radiation induced injuries (burns) from the X-Rays used Angioplasty may also provide a less durable treatment for atherosclerosis, and be more prone to restenosis, relative to vascular bypass or coronary artery bypass grafting. (wikipedia.org)
  • The use of tapered Teflon dilating catheters for the treatment of atherosclerotic vascular disease was first described in 1964 by two interventional radiologists, Charles Dotter and Melvin Judkins, when they used it to treat a case of atherosclerotic disease in the superficial femoral artery of the left leg. (wikipedia.org)
  • Inflatable
  • An inflatable balloon (14) for a catheter (10) includes a coating (15) which causes the balloon to prefer a predetermined, low profile configuration, such as a trifold configuration (40), when deflated. (google.co.uk)
  • 1. An inflatable single layered balloon for a medical device comprising a polymeric material, the polymeric material being a substantially unblended copolymer of polybutylene terephthalate and polytetramethylene ether glycol terephthalate, the copolymer having a flexural modulus of greater than about 150,000 psi. (google.com)
  • Foley catheter, a catheter with an inflatable balloon to retain it in the urinary tract. (wikipedia.org)
  • Arterial
  • Relative to surgery, angioplasty is a lower-risk option for the treatment of the conditions for which it is used, but there are unique and potentially dangerous risks and complications associated with angioplasty: Embolization, or the launching of debris into the bloodstream Arterial rupture from over-inflation of a balloon catheter or the use of an inappropriately large or stiff balloon, or the presence of a calcified target vessel. (wikipedia.org)
  • This was a substantial improvement over bypass surgery in terms of invasiveness, but unfortunately restenosis, a recurrence of arterial clogging, occurred in nearly 50% of patients after the balloon was removed. (wikipedia.org)
  • Teflon is commonly used to reduce friction in biomaterial applications such as in arterial grafts, catheters, and guide wire coatings. (wikipedia.org)
  • Mechanical injury of arterials due to stretching of arterial walls with a balloon catheter results in the recruitment of cells such as monocytes, macrophages, and neutrophils to the site of injury. (wikipedia.org)
  • lumen
  • The shaft has a lumen therethrough with the lumen being in fluid communication with the balloon interior for inflating and deflating the balloon via the shaft lumen. (google.com)
  • The catheter further includes a lumen extension through the balloon, with the lumen extension being in fluid communication with the shaft lumen. (google.com)
  • The resistance to fluid flow past the guide wire in the lumen extension is substantially greater than the resistance to fluid flow between the shaft lumen and the balloon interior. (google.com)
  • A valve member is responsive to the pressure in the balloon interior for blocking fluid flow through the lumen extension during continuing inflation and at least the initial deflation of the balloon. (google.com)
  • insertion
  • They also have a live view of the patients ECG so they can tell whether or not there is a problem being caused by the insertion of the catheter into the heart to the electrical pathways. (wikipedia.org)
  • guidewire
  • The balloon catheter is advanced over a guidewire so that the balloon is positioned adjacent a stenotic lesion. (google.ca)
  • This innovative combination enables physicians to perform high-pressure angioplasty and inject physician-specified fluids, such as contrast, all while maintaining the guidewire position. (aol.com)
  • single layered balloon
  • A balloon catheter, having a non-linear compliance curve, made up of a single layered balloon, that was molded from a polymeric material to have a specific nominal diameter and then shrunk to a diameter that is less than the specific nominal diameter. (google.com)
  • Chest
  • Maximal chest pain score during autoperfusion (3.2 +/- 3.5) was lower than for the pre- (6.1 +/- 2.1, p = 0.003) but not the post- (5.2 +/- 3.1, p = 0.07) standard angioplasty. (ahajournals.org)
  • shaft
  • The balloon catheter may include a catheter shaft and a balloon coupled to the shaft. (google.ca)
  • b) a radially semi-compliant balloon on the shaft, formed at least in part of a polyurethane block copolymer, and having a radial compliance of about 0.025 mm/atm to about 0.045 mm/atm. (google.com)
  • b) an axially noncompliant balloon on the shaft, formed at least in part of a block copolymer. (google.com)
  • significantly
  • The maximum ST-segment elevation and depression in any lead during autoperfusion angioplasty (0.3 +/- 0.5 and 0.6 +/- 0.8 mm) was significantly less than for the pre- (2.4 +/- 1.7 mm, p = 0.002 and 2.2 +/- 1.3 mm, p = 0.0004) or post- (1.9 +/- 1.3 mm, p = 0.002 and 1.6 +/- 1.3 mm, p = 0.018) standard dilatations at the same point in time. (ahajournals.org)
  • treatment
  • Some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. (wikipedia.org)
  • Thrombolytic therapy is indicated for the treatment of STEMI - if it can begin within 12 hours of the onset of symptoms, and the person is eligible based on exclusion criteria, and a coronary angioplasty is not immediately available. (wikipedia.org)
