title: Gallery of medical devices: part 2: devices of the head, neck, spine, chest, and abdomen.
abstract: This gallery of medical devices illustrates a multitude of common devices in the head, neck, spine, chest, and abdomen that are found in daily radiologic practice (orthopedic devices for the extremities and pelvis were illustrated in Part 1). All these medical devices have been more thoroughly discussed in the previous articles in this medical devices series and in other detailed references. The present article is a comprehensive overview of these devices and provides a quick reference for identifying an unfamiliar device. It is intended to allow the reader to identify a device generically and to understand its purpose. It is important to recognize the presence of a device, understand its purpose and proper function, and recognize the complications associated with its use. Knowing the specific or proper brand name of every device is not important and frequently not possible. New devices are constantly being introduced, although most of them are variations of a previous device. Sometimes, so many devices are used in a patient's treatment that they obscure important anatomy and pathologic conditions (Fig 1). Herein, we present an overview of the many medical devices frequently used in the head, neck, and spine, including a halo device, aneurysm clips, spinal fusion devices, deep brain electrodes, sacral nerve stimulator, and vertebroplasty (Figs 2-9). We also illustrate numerous chest medical devices that are seen daily by almost all radiologists. These devices include a multitude of extrathoracic and intrathoracic apparatus, ranging from intravenous catheters to oxygen tubing and electrocardiographic leads, central venous catheters, chest tubes, endotracheal and feeding tubes, cardiac valves, coronary artery bypass stents, pacemakers, internal cardiac defibrillators, ventricular assist devices, and total artificial hearts (the latter two devices are frequently encountered in many large medical centers) (Figs 10-26). We also present medical devices of the abdomen and pelvis, which can be grouped into four major categories: intestinal tubes, genitourinary apparatus, postoperative apparatus, and vascular devices (Figs 27-47). For a detailed discussion of a particular device, the reader should refer to the appropriate references cited.
