  • Patent number: 12016547
    Abstract: An implantable device for aiding in generating connective tissue between a pair of anatomical structures in a mammalian body is provided. The device includes an elongate, flexible tether which can be secured between the anatomical structures and which carries a scaffold which is generally porous so as to be capable of promoting tissue ingrowth and collagen deposition along its length. The scaffold extends along the tether for a sufficient distance so that it is securable in at least close proximity to an anatomical structure at either end. The pores in the scaffold extend through the scaffold and each has a diameter in the range of about 10 ?m to about 200 ?m. The length of the tether is selected to be a desirable maximum distance between the anatomical structures along a desired path when secured therebetween.

  • Patent number: 12004730
    Abstract: Systems and methods for closing a tissue defect are disclosed. The systems may include a subcutaneous guide that is placed transcutaneously between two skin access sites and a self-locking strap that may be advanced into the body through a first access site via a first needle and then passed to a second needle. The strap may be withdrawn with the second needle through a second access site to the outside of the body. The strap may be withdrawn from the first needle, leaving the strap placed through both access sites and across the defect. As the subcutaneous guide is withdrawn from the body it pulls the captured strap such that both ends of the strap protrude from the first access site, allowing the strap to be tightened around the defect. Devices for closure of a tissue defect are also disclosed.
