Patency

Patency refers to the state of being open, unobstructed, or freely accessible, particularly regarding a bodily channel or a conduit, such as a blood vessel, airway, or drainage system. It describes the ability of a passage to allow free flow of fluids or other substances without impediment. This term is crucial in medical contexts, as it signifies that vital pathways are functioning correctly and not constricted or blocked. Lack of patency can lead to severe health complications. It also extends to non-medical contexts, such as describing a clear passage or a valid contract.

Patency meaning with examples

• The surgeon's primary goal during the angioplasty procedure was to restore patency to the blocked coronary artery. By inserting a balloon and stent, they successfully widened the vessel, ensuring blood could flow freely and preventing a heart attack. Post-surgery, the patient's improved circulation was a direct consequence of the restored patency, allowing for better oxygen and nutrient delivery to the heart tissue. This improvement was reflected in the patient's blood flow metrics.
• In patients with glaucoma, the patency of the drainage angle in the eye is crucial for maintaining healthy intraocular pressure. If the drainage channels are blocked, leading to reduced patency, fluid builds up and puts pressure on the optic nerve, potentially causing vision loss. Eye drops are often prescribed to help to widen the angles, encouraging patency and prevent this scenario. Regular eye examinations and the use of prescribed treatments are vital for preserving eye health.
• The lawyer ensured the patency of the contract was confirmed with the proper signatures and initial dates. Any loophole in the contract would have to be resolved to ensure patency. If a term were unclear, the contract would have to be updated to resolve any challenges of patency to be sure the document was enforceable. This ensured that the agreement could withstand legal challenges. The contract needed to be fully open and in-force.
• The engineers focused on maintaining the patency of the ventilation system to ensure a constant and adequate supply of fresh air to the building. Regular maintenance, including filter changes and duct cleaning, was essential to prevent blockages and ensure optimal airflow throughout the building. The airflow should be maintained to allow the fresh air to move with ease. They worked tirelessly to be sure that the air could move freely throughout.
