What is the difference between a rigid and a flexible annuloplasty ring?

CarboMedics - Mechanical Heart Valve, Biological Heart Valve...
A rigid ring, once implanted, fixes the valve in a specific shape. A flexible ring, once implanted, allows the valve to take whatever shape is natural for it and probably can conform to the changes in shape and position of the left atrioventricular junction during the cardiac cycle. Either can be used for mitral valve repair, it is surgeon preference on which they implant. Carbomedics offers both rigid and flexible rings. AnnuloFlo is rigid and AnnuloFlex is flexible.

What is the difference between a rigid and flexible borescope?

FAQs for Hawkeye Borescopes and Accessories
A rigid borescope uses a series of individual lenses or a long gradient index relay lens to relay the image of the objective lens to an image plane where the eye lens can magnify it and present it to the eye for viewing. A flexible borescope uses a coherent fiber bundle with thousands of individual fibers to relay the image from the objective to the eyepiece.

How flexible or rigid can the DPP be?

DPP FAQ
The DPP can be modified across the full spectrum from total rigidity (absolute cylindrical support) to total flexibility. It is a universal spinal orthotic. Its architecture permits the prescribing physician to have the device fitted to meet the exact needs of each patient. It can also be modified to allow for stability and mobility throughout the healing process. No. The DPP is a high technology, revolutionary spinal orthotic unlike anything else available.

What type of duct is recommended, rigid or flexible?

Welcome to NuTone Online
It is recommended, where possible, to use rigid duct. It has less resistance to air flow and allows the fan to operate much more efficiently. If flexible duct is used, be sure the duct is as straight as possible.

Which liner is better, flexible or rigid pipe?

Chimney Lining FAQ - Hart's Hearth
Because of the smooth walls, rigid liner is somewhat better. But the ease of installing flexible liner far out weighs the difference in the smoothness of walls. You have to assemble rigid pipe as you install it and long lengths can mean trouble if you happen to drop the partially assembled pipe down the chimney. A general rule of thumb is if you only need to reline about 12 feet of straight chimney, go with the rigid.

What is the difference between a rigid, semi-rigid, and non-rigid airship ?

FAQ
All airships use an envelope (balloon-like bag of gas) to lift the airship. Some used a metal "skeleton" or frame inside the envelope to give shape to the ship; these were called rigid airships, and examples included the R100 and R101 in England, the Graf Zeppelin and Hindenburg in Germany and the Akron, Macon and Los Angeles in the USA.

What is the difference between a flex (or floppy) and a rigid?

Cadillac Concrete Stamps and Products - Frequently Asked Que...
The rigid mat is double the thickness and has handles. You use the rigid mat to imprint the majority of the stamping job. The floppy has no handles and is about half the thickness of a rigid which allows you to bend the mat at a 90 degree angle. The floppy mat can be used to stamp around the edges of the stamping area, walls, stairs and hard to get at areas.

Will my heart valve or annuloplasty ring be affected by computer tomography?

Mechanical Heart Valve, Biological Heart Valve Questions and...
For most cases, a blood thinner, also known as Coumadin, is typically prescribed for a limited period of time after an annuloplasty repair ring has been implanted. The time frame is generally based on how long it takes the patient's native tissue to seal the ring and no longer present a risk of thrombus/clotting formation.

How long can an annuloplasty ring implant last in a human body?

Mechanical Heart Valve, Biological Heart Valve Questions and...
long as the patient remains in good health after implantation of the ring implant, the annuloplasty ring should last for the remainder of the patient's lifetime. The ring itself should become quickly covered with the patient's native tissue, essentially blending into the background. Valve patients undergoing ANY dental procedure should be considered for prophylactic treatment. Please consult your physician about this prior to visiting a dentist.

I have an annuloplasty ring. Is it safe for me to be tested with MRI?

Mechanical Heart Valve, Biological Heart Valve Questions and...
Yes. All Carbomedics mechanical heart valves and annuloplasty rings have been tested in between the range of 1.5 and 3.0 Tesla for excessive heating and displacement. The test results indicate that no displacement occurred and the impact from heat was negligible. Note however that some image distortion can occur in the vicinity of the valve. The complete report of the test results are available on the website.

Is it possible that I will be allergic to the materials in my annuloplasty ring?

Mechanical Heart Valve, Biological Heart Valve Questions and...
It is very unlikely. However, if you suspect that you might be allergic to polyester, silicone, barium sulfate, titanium, or nitinol, you should discuss it with your surgeon who may arrange for testing prior to your surgery. No. These electrical and magnetic fields are too weak to significantly heat or displace the valve or annuloplasty ring.

Is Flexible Bronchoscope Superior to Rigid Bronchoscope and Will it Replace it?

Bronchoscopist talks to you Balachandran A, Vijaya...
Flexible bronchoscopy as compared to rigid bronchoscope does not require general anaesthesia and can visualise the upper lobe. FBS can visualise up to fourth order bronchus and can be done in ICU or ward setting in case of necessity. This may cause some discomfort to the patient during procedure but is not a painful procedure and has very minimal or nil complications (the total duration of procedure is usually < 5 min). There is no need for infective endocarditis prophylaxis.

Should my child’s shoes be rigid or flexible?

Umi
Ideally, your child's first steps should be cushioned by soft and flexible shoes. With this in mind, we make our children's shoes with leather insoles and leather lining. So they act like a natural, supportive, and non-restrictive "landing pad." Flexible soles are crucial because children's feet must be allowed to move freely. This is important for proper foot development.

Can I use a Dunlopillo mattress on a bedstead with rigid, non-flexible slats?

Dunlopillo - FAQs
Yes, provided the following criteria are met. We recommend spaces of 25mm - 63mm (1" - 2 ½" approx.) between slats no wider than 63mm (2 ½" approx.). You should not use a solid plywood or hardwood base, as condensation will build up on the underside of the mattress due to lack of ventilation.

What is the difference between having a flexible sigmoidoscopy and having a colonoscopy?

Procedures at Gastrointestinal Associates
A sigmoidoscopy is a shorter test that requires less preparation, but is less thorough. A colonoscopy requires greater preparation the day before and sedation for the procedure, but provides a more extensive examination of the colon. It has been shown that up to 50% of polyps and other findings can be missed with a sigmoidoscopy; hence there has been a trend towards performing a coIonoscopy rather than sigmoidoscopy.

What is the difference between a distance ring and an altitude ring?

faq
A distance ring indicates lines of equal distance from a given landout. This is similar to the traditional method of marking up a sectional for cross country flying using a compass and pencil. Marked on each distance ring is the calculated altitude required to make it back to the associated landout, using the current flight parameters. Note that even at the same distance, these values will be different for landouts at different elevations. The areas where rings overlap are omitted for clarity.

Q: What is the difference between a flexible coupling and a flexible hose?

MDC Vacuum Products. - Products FAQ'S- Flanges and Fittings
A: The primary difference is overall length. A flexible coupling is used for short misalignment connections and is defined as a fitting less than 12-inch overall length. In general, a flexible hose is constructed of the same material, but starts at a minimum length of 18-inch and varies in wall thickness. Flexible hose is also available with a protective braiding to provide structural support and to minimize abrasion damage to the formed bellows.
