Publication number: 20210244524Abstract: Collapsible branched anastomosis devices allow for the formation of percutaneous vascular anastomoses using a Seldinger wire technique. This minimally invasive approach eliminates the need for a large surgical incision and also avoids the use of time consuming hand-suturing. The devices collapse to a fraction of their expanded volume and are configured to fit within a delivery sheath for over the wire delivery through a small incision in a blood vessel.Type: ApplicationFiled: August 1, 2019Publication date: August 12, 2021Inventors: Charles T.

Publication number: 20210244525Abstract: Disclosed herein is a stent graft for ascending aorta, comprising a stent; a cover attachment at least partially covering the stent; a valve leaflet for reconstructing aortic valves, which are positioned at the proximal end of the stent and attached to the cover attachment and the stent. The valve leaflet for reconstructing aortic valves is configured to allow blood to flow from the left ventricle to the aorta and prevent blood from flowing from the aorta back to the left ventricle. In addition, the stent graft has two windows aligning with two openings of the coronary artery. Therefore, for the aortic root diseases involving aortic sinus and aortic valves, the stent graft for ascending aorta can be implanted into ascending aortic root by minimally invasive endovascular surgery to repair the ascending aorta lesions and reconstruct the aortic valves, aortic sinus, openings of the coronary artery, thereby achieving overall cure.Type: ApplicationFiled: November 19, 2018Publication date: August 12, 2021Inventors: Zaiping JING, Jiaxuan FENG, Xianhao BAO, Rui FENG, Jian ZHOU, Qingsheng LU, Tao LI, Junmin BAO, Zhiqing ZHAO, Huajuan MAO, Yufeng ZHUANG

Publication number: 20210244526Abstract: An intravascular implant and methods of using the implant within the vasculature of the body, for example near a vascular aneurysm, are disclosed. A method of treating an aneurysm includes positioning a vascular graft comprising a tubular channel having a first end and a second end in a blood vessel, securing the vascular graft in place with an expandable anchoring member, and filling a seal cuff on the vascular graft, wherein the seal cuff extends radially outward beyond an exterior surface of the vascular graft, wherein the seal cuff comprises a first seal portion and a second seal portion and wherein the first seal portion is separated from the second seal portion by a first gap and a second gap along a circumference of the seal cuff.Type: ApplicationFiled: February 22, 2021Publication date: August 12, 2021Inventor: Thomas J.

Publication number: 20210244527Abstract: A silicone prosthesis delivery apparatus and associated methods are disclosed for facilitating the insertion of a silicone prosthesis into a surgically developed pocket of a patient. In at least one embodiment, a flexible, substantially hourglass-shaped delivery sleeve is configured for receiving and subsequently expelling the prosthesis therefrom. The delivery sleeve provides a substantially conical-shaped transfer channel and a substantially conical-shaped delivery chamber, the transfer channel and delivery chamber opposingly positioned and joined with one another so as to form a relatively smaller diameter passage therebetween. A free end of the transfer channel provides an entry opening configured for allowing the prosthesis to selectively pass therethrough when the prosthesis is inserted into the delivery sleeve, and a free end of the delivery chamber provides a closed end.Type: ApplicationFiled: February 1, 2021Publication date: August 12, 2021Applicant: Conical Cover LLCInventor: Scott Hyler Heneveld

Publication number: 20210244531Abstract: An exchangeable lens platform (ELP) comprises a horseshoe-shaped ring structure, which has a memory strip incorporated therein, into which the haptic end components of the intraocular lens (IOL) can engage diametrically opposite portions of the ring structure. In this manner, the exchangeable lens platform (ELP) can not only be opened or expanded so as to be disposed within any sized capsular bag in a secure and stabilized manner, but diametrically opposite portions of the exchangeable lens platform (ELP) can effectively fold upon themselves such that the exchangeable lens platform (ELP) will effectively be partially folded in half such that the diametrically opposite folded portions of the exchangeable lens platform (ELP) can effectively engage diametrically opposed internal wall portions of the fornix of the capsular bag so as to permit the intraocular lens (IOL) to then be properly centered, oriented, stabilized, and secured within the eye.Type: ApplicationFiled: February 9, 2021Publication date: August 12, 2021Inventor: Jeffrey WHITSETT
