Anterior Cervical Discectomy and Fusion Anterior Cervical Discectomy and Fusion is cervical spine surgery from the front of the neck that addresses spinal symptoms.
Autologous Chondrocyte Implantation A technique for the treatment of large isolated cartilage defects. A small sample of cartilage is harvested from a non-weight-bearing part of the joint during arthroscopy. In a laboratory the chondrocytes are dissolved away of the tissue composite and multiplied in culture dishes. After a cultivation period of 3 to 4 weeks …

Atomic Layer Deposition ALD uses timed pulses of reactive precursors to encapsulate all exposed surfaces of a substrate for coating. It gets its name from the nature of these pulses, each of which deposits a single self-terminating layer. It is a subclass of chemical vapour deposition (CVD). The coating can be controlled with atomic precision.
Anterior Lumbar Interbody Fusion ALIF is a procedure where surgeons work on the lower spine from the front and fuse one or more vertebrae together.
A nonbiologic material such as metal, ceramic, and plastic.

Arthrodesis (also artificial ankylosis or syndesis), is the artificial induction of joint ossification between two bones by surgery. This is done to relieve intractable pain in a joint which cannot be managed otherwise. It is most commonly performed on joints in the spine, hand, ankle, and foot.
The artificial kidney is not available yet. Researchers are working on it and the first implanted artificial kidney is expected in 2017. USCSF The new device being developed by a group of US universities within the Kidney Project. This small bio-artificial kidney, intended to treat end-stage renal disease (ESRD), will offer new hope to those …
atrial septal defect An Atrial Septal Defect (ASD) is a common congenital cardiac defect that consists of a hole in the septum between the two filling chambers of the heart, the atriums.

ACI (Autologous chondrocyte implantation) repairs articular cartilage. It works in three stages: 1. Arthroscopically sampling of 200 to 300 mg cartilage. 2. Isolated chondrocytes are grown in vitro for about four to six weeks. 3. Chondrocytes are applied in a second intervention on the damaged area. The autologous cells should adapt themselves to their new …
