Abstract: Devices, systems and methods are disclosed for repairing soft tissue. The surgical system allows for the creation of tissue repair by grasping, aligning and sewing or fixing tissue. For example, this system may be used for clipping together excessive capsular tissue and reducing the overall capsular volume. The deployment device includes a central grasping mechanism and an outer clip delivery system. The clip embodiments may be single or multi-component (penetration and locking base components) that penetrate tissue layers and deploy or lock to clip the tissue together. An example of the system is used to reduce the joint capsule tissue laxity and reduces the potential for subluxation or dislocation of the joint by either restricting inferior laxity (anterior or posterior) and resolving or eliminating pathologic anterior or posterior translation.

Abstract: Devices and methods for treating degenerative, congestive heart disease and related dysfunction are described. Passive and active cardiac support structures mitigate changes in ventricular structure (i.e., remodeling) and deterioration of global left ventricular performance related to tissue damage precipitating from ischemia, acute myocardial infarction (AMI) or other abnormalities. Cardiac efficiency is improved by providing reinforcement that restores or maintains an elliptical ventricular shape and mimics the position and positive inotropic effects of helical wound myofibrils to provide active contraction of the ventricle in synchrony with the metabolically required cardiac pace or output. In addition, the cardiac support structures compensate or provide therapeutic treatment for congestive heart failure and/or reverse the remodeling that produces an enlarged heart.
Abstract: Devices and methods are disclosed for assisting in blood flow from a weakened or injured heart, particularly for pediatric patients. A low profile, multi-chambered implantable mechanism is used to collect blood from a blood vessel and re-pump the blood out with an induced pressure emanating from a fluid pressure source. The devices and methods described herein are easy to use and may be attachable to body tissue without use of suture anastomosis.
