Information Storage and Retrieval Definition: A branch of computer or library science relating to the storage, locating, searching, and selecting, upon demand, relevant data on a given subject.
Information Storage and Retrieval Definition: A branch of computer or library science relating to the storage, locating, searching, and selecting, upon demand, relevant data on a given subject.
MEDLARS Definition: A computerized biomedical bibliographic storage and retrieval system operated by the NATIONAL LIBRARY OF MEDICINE. MEDLARS stands for Medical Literature Analysis and Retrieval System, which was first introduced in 1964 and evolved into an online system in 1971 called MEDLINE (MEDLARS Online). As other online databases were developed, MEDLARS became the name of the entire NLM information system while MEDLINE became the name of the premier database. MEDLARS was used to produce the former printed Cumulated Index Medicus, and the printed monthly Index Medicus, until that publication ceased in December 2004.

Catheters, Vascular, Retrieval, Snare Definition: Catheters designed for the minimally invasive retrieval of embolized fragments in a blood vessel. Vascular retrieval catheters typically consist of tubes with end and/or side holes and long, flexible wires looped and inserted in their lumens. Two variations are typical: In one model, the loop emerges from the distal tip of the catheter while both free ends of the wire emerge from the proximal end; in another model, one end of the wire is attached to the distal end of the catheter while the free end is passed through the lumen to emerge at the proximal end. Some catheters configure snare loops at right angles to the catheter to facilitate successful retrieval. The wire is usually made of a strong, stiff alloy (e.g., nickel titanium). Snare catheters are very effective when used to entrap an embolized fragment that presents a free end.
Retrieval Baskets, Biliary Stone Definition: Instruments designed to trap, retrieve, and/or manipulate stones for the treatment of conditions such as cholelithiasis (i.e., presence of calculi in the bile duct or gallbladder). These instruments typically comprise a flexible sheath with a multiwire, self-expanding (typically nitinol) basket at the distal end and a handle at the proximal end designed to open, close, and rotate the basket. These devices are intended to be used through the working channel of an endoscope in procedures such as endoscopic retrograde cholangiopancreatography (ERCP) or laparoscopic cholecystectomy.
Retrieval Baskets, Urological Stone Definition: Instruments designed to trap, retrieve, and/or manipulate stones for the treatment of conditions such as nephrolithiasis and urolithiasis (i.e., presence of calculi in the kidneys or urinary tract). These instruments typically comprise a flexible sheath with a multiwire, self-expanding (typically nitinol) basket at the distal end and a handle at the proximal end to open, close, and rotate the basket. These devices are intended to be used through the working channel of an endoscope, such as a nephroscope or ureteroscope, during urological and related procedures.
Sperm Retrieval Definition: Procedures to obtain viable sperm from the male reproductive tract, including the TESTES, the EPIDIDYMIS, or the VAS DEFERENS.
Oocyte Retrieval Definition: Procedures to obtain viable OOCYTES from the host. Oocytes most often are collected by needle aspiration from OVARIAN FOLLICLES before OVULATION.
DEVICE, PERCUTANEOUS RETRIEVAL Definition: An embolectomy catheter is a balloon-tipped catheter that is used to remove thromboemboli, i.e., blood clots which have migrated in blood vessels from one site in the vascular tree to another.
Catheters, Biliary, Retrieval, Balloon Definition: Retrieval biliary catheters designed for extraction of calculi from the biliary tree. These catheters include a rounded distal tip that incorporates a balloon; typically, they are 2 mm in diameter when the balloon in uninflated more than 12 mm in diameter at maximum inflation. Gallstone extraction catheters are introduced into the common bile duct, the hepatic ducts, and/or the major hepatic biliary radicles (e.g., through a choledochostomy) and advanced past any calculi in the involved duct. The balloon is then inflated and gently withdrawn, bringing the stones with it. Gallstone extraction catheters are mostly used for extraction of intrahepatic duct stones; they may also be used for retrieval of foreign bodies in the biliary tree.
Catheters, Urinary, Ureteral, Retrieval Definition: Ureteral catheters designed to retrieve stones and foreign bodies (e.g., catheter tips, stents, other debris) from the upper urinary tract. Several different catheters are used for vascular retrieval, including loop snare and helical baskets; some of them may be used for stone fragmentation before retrieval.
Catheters, Vascular, Retrieval Definition: Vascular catheters designed to retrieve foreign bodies (e.g., catheter tips, guide-wire fragments, stents, bullets, and other debris) from the central or peripheral vessels or from the heart. Several different catheters are used for vascular retrieval of foreign objects, including loop snare, helical basket, hooked, pigtail, grasping forceps, and modified myocardial biopsy catheters. These catheters are used for recuperation of foreign bodies using percutaneous techniques obviating the need for surgical removal.
Catheters, Vascular, Retrieval, Basket Definition: Vascular retrieval catheters that consist of end-hole catheters, which include a core wire. A set of four wires helically twisted are joined at their distal tip and attached to the core wire, forming a flexible basket-like structure. These catheters are mostly used in children and in smaller vessels because of their small outside diameter; the embolized fragment must present a free end for effective ensnarement.
Catheters, Vascular, Retrieval, Grasping Definition: Vascular retrieval catheters that include forceps for grasping and removal of foreign objects. These catheters may include flexible forceps mounted on a small-lumen (e.g., 3 Fr) stainless steel shaft; single-tooth (rat tooth) and multiple-tooth (alligator type) forceps are available. Grasping retrieval catheters can grab an object any place along its length, including the middle portion, eliminating the need for repositioning of the object as an initial stage to the procedure. Positioning the catheter immediately adjacent to the foreign body before exposing the forceps is recommended to minimize the risk of vascular injury.
Catheters, Biliary, Retrieval Definition: Biliary catheters designed to retrieve foreign bodies (e.g., catheter tips, guide wire fragments, stents, other debris) and gallstones from the biliary tree or pancreatic ducts. Several different catheters are used for retrieval, including loop snare, helical basket, hooked, grasping forceps, and balloon tipped. These catheters are used for recuperation of foreign bodies and gallstones using percutaneous techniques that obviate the need for surgical removal.
synaptic vesicle retrieval Definition: OBSOLETE. Return of a vesicle from the postsynaptic membrane to presynaptic membrane. [http://cancerweb.ncl.ac.uk, http://www.stedmans.com/]
Retrieval Definition: The operation of accessing information or removing an item from storage.
Computer Retrieval of Information on Scientific Projects Database Definition: The Computer Retrieval of Information on Scientific Projects Database (CRISP) is a searchable database of federally funded biomedical research projects maintained by the Office of Extramural Research at NIH. It includes projects funded by NIH, Substance Abuse and Mental Health Services Administration, Health Resources and Services Administration, Food and Drug Administration, Centers for Disease Control and Prevention, Agency for Healthcare Research and Quality, and Office of Assistant Secretary of Health.
