  • body

  • Acidosis An acidic condition in body fluids, chiefly blood. (wikipedia.org)
  • Anti-diabetic drug A kind of medication that helps a person with diabetes control the level of glucose (sugar) in the blood so that the body works as it should. (wikipedia.org)
  • tissue
  • Once the TRAM free flap is transposed to the woman's chest, the epigastric blood vessels are anastomosed (connected) to the internal thoracic vein to maintain the tissue viability of the reconstructed breast. (wikipedia.org)
  • because it possesses a robust blood supply, there is a low risk of tissue necrosis, either of the flap or of the adipocyte fat, and the reconstructed breast can tolerate oncologic radiotherapy. (wikipedia.org)
  • Tissue heart valves, in contrast, do not require the use of anticoagulant drugs due to the improved blood flow dynamics resulting in less red cell damage and hence less clot formation. (wikipedia.org)
  • polymer
  • 1. An endoluminal prosthesis, comprising an elongate support wire member joined alone an entire length thereof to at least one surface of a strip of polymer cladding, the joined support wire member and polymer cladding being helically wrapped into an open cylindrical structure such that adjacent windings of the polymer cladding have overlapping regions that are bonded to one another forming said prosthesis. (google.com)
  • made
  • Though often referred to as a glass eye, the ocular prosthesis roughly takes the shape of a convex shell and is made of medical grade plastic acrylic. (wikipedia.org)
  • In some countries, Germany especially, prostheses are still most commonly made from glass. (wikipedia.org)
  • replacement
  • Polymethyl methacrylate (PMMA) (acrylic) Polymethyl methacrylate (PMMA) is a transparent thermoplastic available for use as ocular prosthesis, replacement intraocular lenses when the original lens has been removed in the treatment of cataracts and has historically been used as hard contact lenses. (wikipedia.org)
  • thrombus
  • Several microangiopathic diseases, including disseminated intravascular coagulation and thrombotic microangiopathies, generate fibrin strands that sever red blood cells as they try to move past a thrombus, creating schistocytes. (wikipedia.org)
  • structure
  • Natural heart valves are evolved to forms that perform the functional requirement of inducing unidirectional blood flow through the valve structure from one chamber of the heart to another. (wikipedia.org)
  • treatment
  • citation needed] However, current mechanical heart valves all require lifelong treatment with anticoagulants (blood thinners), e.g. warfarin, which requires monthly blood tests to monitor. (wikipedia.org)
  • claim
  • 2. The endoluminal prosthesis according to claim 1 , further comprising a planar polytetrafluoroethylene film member in intimate contact with and monolithically joined to the planar expanded polytetrafluoroethylene film member, the support wire member being intermediate the second planar expanded polytetrafluoroethylene film member and the planar expanded polytetrafluoroethylene film member. (google.ca)
  • 3. The endoluminal prosthesis according to claim 1 , further comprising a bonding agent joining the support wire member and the planar expanded polytetrafluoroethylene film member. (google.ca)
  • 4. The endoluminal prosthesis according to claim 2 , further comprising an adhesive interlayer interdisposed between the planar polytetrafluoroethylene film member and the planar expanded polytetrafluoroethylene film member. (google.ca)
  • metal
  • The metal ring holds, by means of two metal supports, a disc which opens and closes as the heart pumps blood through the valve. (wikipedia.org)
  • plastic
  • clarification needed] It is used in high temperature applications such as missile nose cones, rocket motors, heat shields, laboratory furnaces, in graphite-reinforced plastic, and in biomedical prostheses. (wikipedia.org)
  • high
  • Cross match of blood is routine also, as a high percentage of patients receive a blood transfusion. (wikipedia.org)
  • The force from the blood flow over the high pressure gradient from the prosthesis leads to fragmentation of red cells, and schistocyte formation. (wikipedia.org)
  • found
  • The earliest known evidence of the use of ocular prosthesis is that of a woman found in Shahr-I Sokhta, Iran dating back to 2900-2800 BCE. (wikipedia.org)
  • However, he found running difficult and uncomfortable as his prosthesis was not designed for the purpose, and frequently got damaged. (wikipedia.org)
  • Medical
  • The clinical advantage of the free-flap breast reconstruction procedure is avoidance of the medical complications-infection, malposition of the breast implant(s), capsular contracture-which occasionally occur consequent to breast-reconstruction surgery procedures that emplace breast prostheses to the mastectomy wounds. (wikipedia.org)
  • flow
  • When blood pressure in the chamber of the heart exceeds that of the pressure on the outside of the chamber the ball is pushed against the cage and allows blood to flow. (wikipedia.org)
  • Red cells get trapped in the fibrin strands of the microthrombi and become sheared by the force of blood flow leading to schistocyte formation. (wikipedia.org)
  • wire
  • 1. An endoluminal prosthesis comprising an elongate support wire member joined along its length to an elongate planar expanded polytetrafluoroethylene film member, the joined support wire member and planar expanded polytetrafluoroethylene film member being helically wound into an open cylindrical configuration with adjacent windings forming overlapping regions of the expanded polytetrafluoroethylene film member bonded to one another. (google.ca)
  • known
  • A variant of the ocular prosthesis is a very thin hard shell known as a scleral shell which can be worn over a damaged or eviscerated eye. (wikipedia.org)
  • mechanical
  • Schistocyte formation occurs as a result of mechanical destruction (fragmentation hemolysis) of a normal red blood cell. (wikipedia.org)
  • surgery
  • The division of the superior epigastric blood supply, by a previous surgery, precludes a pedicled TRAM flap as the feasible method for breast reconstruction. (wikipedia.org)
  • past
  • He also started running in the summer of 2003 as soon as he had his prosthesis fitted: "I love that sound of air rushing past your ears and the freedom of it. (wikipedia.org)
  • supply
  • The main concern is strangulation, where the blood supply to part of the bowel is blocked. (wikipedia.org)
  • They may be chronic, although painless, and can lead to strangulation (loss of blood supply), obstruction (kinking of intestine), or both. (wikipedia.org)
  • pressure
  • A class of drugs used to decrease hypertension, mainly by interfering with the renin kidney-blood pressure control cycle. (wikipedia.org)
  • An agent which interferes with the renin (kidney-lung-heart blood pressure control) cycle. (wikipedia.org)
