UI	MeSH Term	Description	Entries
D007440	Intubation	Introduction of a tube into a hollow organ to restore or maintain patency if obstructed. It is differentiated from CATHETERIZATION in that the insertion of a catheter is usually performed for the introducing or withdrawing of fluids from the body.	Intubations
D007767	Lacrimal Duct Obstruction	Interference with the secretion of tears by the lacrimal glands. Obstruction of the LACRIMAL SAC or NASOLACRIMAL DUCT causing acute or chronic inflammation of the lacrimal sac (DACRYOCYSTITIS). It is caused also in infants by failure of the nasolacrimal duct to open into the inferior meatus and occurs about the third week of life. In adults occlusion may occur spontaneously or after injury or nasal disease.

D009301	Nasolacrimal Duct	A tubular duct that conveys TEARS from the LACRIMAL GLAND to the nose.	Lacrimal Sac,Tear Duct,Duct, Nasolacrimal,Duct, Tear,Ducts, Nasolacrimal,Ducts, Tear,Lacrimal Sacs,Nasolacrimal Ducts,Sac, Lacrimal,Sacs, Lacrimal,Tear Ducts
D002404	Catheterization	Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.	Cannulation,Cannulations,Catheterizations
D003608	Dacryocystorhinostomy	Surgical fistulization of the LACRIMAL SAC for external drainage of an obstructed nasolacrimal duct.	Dacryocystostomy,Dacryocystorhinostomies,Dacryocystostomies
D004724	Endoscopy	Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.

D012826	Silicone Elastomers	Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.	Elastomers, Silicone,Rubber Silicone,Silicone Rubber,Elastosil,Microfil,SE-30,Elastosils,Microfils,SE 30,SE30,Silicone Elastomer
