(Latin: to curdle; from a verb meaning "to bring together")

anticoagulant
A medicine that prevents or retards the clotting of blood.
chemocoagulation
In surgery, the coagulation of tissue by applying chemicals.
coagulant
1. An agent that produces coagulation or which converts a fluid or a substance that is in a solution into a solid or gel.
2. An agent that causes, stimulates, or accelerates coagulation, especially with reference to blood.
3. Etymology: from Middle French coaguler, from Ltin coagulatus, past participle of coagulare, "to cause to curdle"; from cogere, "to curdle, to collect"; from com-, "together" + agere "to drive".
coagulate (verb), coagulates; coagulated; coagulating
1. To convert, to clot, or to curdle a fluid or a substance that is in a solution into a solid or a gel.

coagulopathy
Disease affecting the coagulability of the blood.
electrocoagulation, surgical diathermy
1. A procedure that uses an electrical current to stop bleeding.
2. A therapeutic destructive form of electrosurgery in which tissue is hardened by the passage of high-frequency current from an electric cautery device.
3. A method of sealing blood vessels using heat generated by high-frequency electric current through fine needles or an electrical surgical knife.

The procedure is used during surgery to close newly cut vessels and it can also be used to stop nosebleeds and to remove vascular deformities.

photocoagulation
1. Condensation of protein material by the controlled use of an intense beam of light; used especially in the treatment of retinal detachment and the destruction of abnormal retinal vessels, or of intraocular tumor masses.
2. A technique using intense light energy, as from a laser, to produce scar tissue used in treating certain eye disorders, in medical and biological research, etc.
thermocoagulation
1. The process of converting tissue into a gel by heat.
2. Coagulation of tissue by the action of high-frequency currents; used in removal of growths and also used to produce stereotactic lesions in the brain.
3. Destruction and removal of tissue by coagulation utilizing high-frequency electric current.
