Hemostasis via vessel coagulation and sealing by heat application

The term "hemostasis via vessel coagulation/sealing by heat application" does not refer to a specific molecule, receptor, enzyme, or canonical drug target. Instead, it describes a physical process used in surgery where heat energy is applied to blood vessels—typically using devices such as bipolar electrosurgical instruments or ultrasonic scalpels—to denature proteins within the vessel wall. This protein denaturation causes the proteins to become sticky and form a coagulum that seals the lumen of the blood vessel and prevents bleeding[4][7]. The process relies on direct thermal effects rather than interaction with any particular molecular target. During this procedure, temperatures can range from 50°C up to 400°C depending on device type and settings. At these temperatures, tissue proteins unravel and cross-link through new hydrogen bonds between adjacent chains, resulting in an effective seal that occludes blood flow through the treated segment of the vessel[4][7]. Devices such as Ligasure™, Harmonic Scalpel™, Gyrus™, and others are commonly used for this purpose during minimally invasive or open surgeries. This approach is fundamentally different from pharmacologic modulation of hemostasis (e.g., targeting thrombin or platelet receptors), as it does not involve specific molecular targets but instead uses physical means to achieve rapid hemostasis during surgical procedures. Because "hemostasis via vessel coagulation/sealing by heat application" refers only to a technique—not a discrete biological molecule—it should not be classified as a therapeutic target like an enzyme or receptor. Therefore: > There is something incorrect about considering "hemostasis via vessel coagulation/sealing by heat application" as a canonical druggable target; it describes *a method* rather than *a molecule* involved in disease biology or therapy[4][7]. If you need structured information about actual molecular targets involved in physiological hemostasis (such as thrombin [F2], fibrinogen [FGA/B/G], von Willebrand factor [VWF], etc.), please specify which component you are interested in.
