Endothelium

Endothelium: the single layer of endothelial cells lining all blood vessels and lymphatics; term coined by Wilhelm His in 1865; a dynamic organ regulating vascular tone, permeability, hemostasis, inflammation, and angiogenesis, with dysfunction central to atherosclerosis.

Endothermic process

An endothermic process, also called an endothermic reaction or endoergic, is a physical or chemical change that absorbs heat from its surroundings, giving a positive enthalpy change.

Endotics

Endotics is a disposable, worm-like robotic colonoscopy system by Italy's Era Endoscopy that advances through the colon on its own, reducing pain; FDA cleared in 2020, it is the only robotic colonoscopy system in clinical use.

Endotracheal anesthesia

Endotracheal anesthesia is general anesthesia in which anesthetic gases or vapors are delivered through a tube placed in the trachea, preventing airway obstruction and aspiration during surgery.

Endotronix

Endotronix was a privately held medtech company in Lisle, Illinois, founded in 2007, that developed the Cordella heart failure system, an implantable pulmonary artery pressure sensor.

Endovascular aneurysm repair

Endovascular aneurysm repair (EVAR), also called stent-graft repair including TEVAR and fenestrated/branched EVAR, treats aortic aneurysms via femoral access; lower perioperative mortality than open repair but higher reintervention, endoleak, and lifelong surveillance.

Endovascular coiling

Endovascular coiling is a minimally invasive procedure that fills a brain aneurysm sac with detachable platinum coils delivered through a catheter, the main alternative to surgical clipping.

Endovascular extravillous trophoblast cell

Endovascular extravillous trophoblast (enEVT, endovascular trophoblast, EndTb): a fetal trophoblast subtype that invades uterine spiral arteries, replaces endothelium, plugs vessels until ~12 weeks, and remodels them 5-10 fold; failure causes preeclampsia and fetal growth restriction.

Endovascular Procedures

Endovascular procedures (intravascular, endovascular techniques) are minimally invasive catheter-based procedures inside blood vessels for diagnosis and treatment: angioplasty, stenting, thrombectomy, embolization, EVAR; lower early morbidity than open surgery but more reinterventions.

Endovascular reconstruction

Endovascular reconstruction is a minimally invasive treatment in which catheter-delivered stents and flow diverters rebuild a diseased or aneurysmal blood vessel from inside, excluding the aneurysm while preserving flow.

Endovascular thrombectomy for ischemic stroke

Endovascular thrombectomy (EVT), or mechanical thrombectomy, removes clots causing large vessel occlusion ischemic stroke via catheter devices (stent retriever or aspiration). Established by 2015 trials; 2026 AHA/ASA guideline extends windows and eligibility.

Endovenous ablation

Endovenous ablation, including endovenous laser ablation, is a minimally invasive procedure using laser, radiofrequency, or steam energy to permanently close incompetent veins, treating varicose veins.

Endovenous laser treatment

Endovenous laser treatment (EVLT, EVLA) is a minimally invasive, local-anesthetic day procedure sealing incompetent leg veins with intravenous laser heat, first performed in Spain in 1998 with an 810-nm diode laser; occlusion exceeds 90% and matches surgery with fewer complications.

Endowment (Mormonism)

The Mormon endowment, also called the temple endowment ceremony, is a Latter-day Saint temple ordinance of instruction on the plan of salvation and covenants, first given by Joseph Smith in 1842.

Endowment effect

Endowment effect: owners value goods more than non-owners; WTA exceeds WTP, often by more than 2x. Named by Thaler (1980), shown in Kahneman-Knetsch-Thaler mug experiments; explained by loss aversion and alternatives.

Endozoicomonas

Endozoicomonas, genus of marine Gammaproteobacteria in Oceanospirillales (family Endozoicomonadaceae), symbionts of corals, sponges, molluscs, and fish; roles span mutualism to parasitism, with carbohydrate metabolism, type III secretion, and cophylogeny with hosts.

Endpoint detection and response

Endpoint detection and response (EDR) is a category of security software that continuously collects telemetry from laptops, desktops, and servers to detect suspicious activity and support investigation.

Endra

Endra is a Stockholm-based AI startup founded by Anton Juric and Niklas Lindgren that builds an AI platform for MEP engineering design, sold to engineering consultancies.
