Abstract

Delivery devices for delivering encircling implants can include two separate limbs that are held together at a distal articulation by the implant being delivered. The implant can comprise a suture and/or a braided tube. The implant can extend through or over the limbs. The implant and at least a distal portion of the limbs can be compressible into a delivery shape that allows for advancement through the lumen of a delivery catheter. When the distal portion of the limbs move out of the delivery catheter, the limbs and implant can resiliently assume a loop shape that is complementary to a shape of a target around which the encircling implant is to be placed. The limbs are then retracted from along the implant to leave the implant in the desired delivery position. The delivery device can be used to place encircling implants around the heart or other targets, and the implant can be tightened to exert compressive force on the target.
