Patent number: 9504457Abstract: Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from prior interventional procedures. A sealing member is deployed intravascularly into the target vessel, and an anchor member is deployed extravacularly of the target vessel. The sealing member and the anchor member are connected by a suture that may be drawn to tighten the sealing member and the anchor member relative to one another in order to effect the seal of the puncture wound. After tightening, the suture is secured to maintain the sealing member and the anchor member relative to one another in order to maintain the seal. Preferably, the anchor member, the suture and the sealing member are comprised of biocompatible, bioresorbable materials that are absorbed into the body after the sealing of the puncture wound has been achieved.Type: GrantFiled: July 15, 2011Date of Patent: November 29, 2016Assignee: Cardinal Health Switzerland 515 GmbHInventors: David Szabo, David Gale, Paul Johnson, Valerie Scott, Ben Morris, Greg Furnish, Trevor Beckett, Michael J.

Patent number: 9486229Abstract: Various apparatus and methods for excising tissue are described therein. In certain variations, a method of excising a target tissue mass from a subject, may include advancing an elongate instrument having an opening at its distal end into a subject. A cutting element, e.g., a snare or loop, may be advanced from the distal end of the elongate instrument, wherein the cutting element may be configured to cut tissue. The cutting element may be positioned near the target tissue mass. The cutting element may be actuated, e.g., expanded or deployed, and may perform energy based or mechanical cutting of a section of tissue encapsulating the target tissue mass. The cut section of tissue and the target tissue mass encapsulated therein may be removed from the subject.Type: GrantFiled: May 11, 2012Date of Patent: November 8, 2016Assignee: Broncus Medical Inc.Inventor: Michael D.

Patent number: 9480549Abstract: Embodiments of the present invention encompass anti-adhesion wound dressings including patches made from amnion tissue obtained from human birth tissue. Exemplary amnion patches can be fabricated by folding a section of amnion over on itself with the epithelial layer on the outside of the folded patch and the fibroblast layer on the inside of the folded patch. Optionally, individual amnion tissue pieces can be sandwiched together to provide a multi-layer patch. Sufficient pressure is applied to the layered amnion to cause adherence between opposing faces of the fibroblast layers. The pressed fibroblast layers provide mechanical strength to hold the amnion patch together with the epithelial layers on the outsides of the amnion patch.Type: GrantFiled: March 11, 2013Date of Patent: November 1, 2016Assignee: AlloSourceInventor: Adrian C.

Patent number: 9277935Abstract: Devices and methods for treating a target site in a body lumen are provided. A medical device includes a stent-like structure including a plurality of scoring and non-scoring filaments interwoven with one another. Generally, the stent-like structure will have more non-scoring filaments than scoring filaments to provide greater structural support and to focus the scoring forces on only a few select areas. The stent-like structure is expanded within the target site to score the target site and to provide temporary structural support while the target site is infused with a therapeutic agent. Such therapeutic agent infusion occurs with the use of a drug eluting or drug coated balloon disposed within the stent-like structure or by occluding the target site and introducing a drug into the occluded target site to sit for a period of time.Type: GrantFiled: November 15, 2013Date of Patent: March 8, 2016Assignee: Quadra Endovascular, Inc.Inventor: Richard Eustis Fulton, III
