Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut For over 4000 years, sutures have been used as a medical intervention. The earliest records indicate linen was the biomaterial of choice. Catgut, which is still in use today, was reportedly used to treat gladiators around 150 AD. Today, there are numerous materials being used for sutures. Sutures are classified by their composition (natural or...

Survivors of acute respiratory distress syndrome (ARDS) and critical illness frequently develop long-lasting muscle weakness. Manual muscle testing (MMT) is a standardized clinical examination commonly used to measure strength of peripheral skeletal muscle groups. This video demonstrates MMT using the 6-point Medical Research Council scale.

Binary Acids and Bases In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
FAQs
Measured burst strength reflects more than the material itself. Wall thickness, vessel or conduit geometry, and structural defects all contribute to how pressure is distributed and where failure begins. Consequently, two specimens made from similar materials can withstand different maximum pressures. Controlling or documenting these features is essential when comparing bioengineered constructs or deciding whether a design meets its intended pressure-bearing requirement.
Pressure identifies the load applied at each stage, while deformation shows how the specimen responds as that load increases. Examining both signals helps relate structural changes to the eventual failure point rather than treating burst pressure as an isolated number. This combined record supports more informative comparisons among vascular grafts, tissue-engineered conduits, catheters, and other pressure-bearing constructs.
Controlled conditions make differences between specimens easier to attribute to design, material, thickness, geometry, or defects rather than inconsistent testing. The specimen is pressurized gradually, and pressure, deformation, and failure are recorded in a consistent sequence. Such standardization improves the value of comparisons used for device selection, quality control, and development of safer biomedical implants.
The process begins by placing the material, vessel, or tubular construct under a controlled internal-pressure test. Pressure is then increased gradually while the system records pressure and deformation. Testing continues until the specimen ruptures, establishing the maximum pressure it withstands. The resulting value can then be compared across designs, provided relevant structural features and test conditions are documented.
Applications include vascular grafts, tissue-engineered conduits, catheters, and other biomedical devices that must maintain integrity under internal pressure. For these products, the measurement provides a direct basis for judging pressure-bearing capacity. It can help researchers and developers compare candidate designs, identify suitable constructs, and assess whether an implant is appropriate for continued development or quality-control review.
Burst pressure results support comparisons rather than serving as the only description of a construct. Interpreting the value alongside deformation, failure point, wall thickness, geometry, and structural defects gives a fuller view of mechanical integrity. This information can guide device selection, quality control, and safer development of implants intended to withstand physiological or laboratory loading.
