Percutaneous Tendon-Muscle-Ligament Approximation Device

摘要

A device for the approximation of tissue including a hollow tube housing an inner core. The inner core may be moved within the hollow tube between first and second positions. The inner core comprises a distal tip. When the inner core is placed into the first position, the distal tip extends away from or outside of the hollow tube such that the distal tip may become securely attached to a selected tissue at a desired location. Once secured to tissue, the distal tip is configured to approximate the torn tissue in a selected direction. Associated systems and methods are also disclosed.

1. A tissue approximation device comprising:
a hollow tube having a distal portion; an inner core, housed within the hollow tube, the inner core being movable within the hollow tube between a first position and a second position, wherein the inner core comprises a distal tip and wherein placing the inner core in the first position causes the distal tip to be deployed outside of the distal portion of the hollow tube to secure biological tissue, and wherein placing the inner core in the second position causes the distal tip to be retracted into the interior of the hollow tube; a device control in mechanical communication with the hollow tube and the inner core providing for the inner core to be selectively placed in the first position and the second position; and a stabilizer operatively associated with the hollow tube positioned to abut a surface when the hollow tube is inserted to a selected depth into biological tissue.
