摘要:
Annuloplasty rings are employed to treat heart valve defects, such as regurgitation. Synching the heart tissue to the ring restores the valve opening to its approximate original size and operating efficiency. Adjustable annuloplasty rings allow for a proper degree of synching both during open heart surgery and over the patients lifetime. A subcutaneous port may be coupled to an adjustable annuloplasty ring such that an external activation energy generator can be used to heat the adjustable annuloplasty ring and thereby adjust the size of the annuloplasty ring.
