Patent number: 10751176Abstract: The methods and devices disclosed herein promote temporal control of balloon inflation patterns. The devices include a covering for a portion of the balloon that compresses the balloon portion during the inflation process. This enables the distal portion of a balloon to be inflated prior to the proximal portion of a balloon, creating a tapered shape at lower inflation pressures. This is especially useful during transvascular implantation procedures, as it prevents dislodgement of an implant mounted on the balloon. As inflation continues, pressure exerted on the balloon by the covering is overcome such that the proximal region of the balloon inflates, forming a shape with generally straighter sides than the tapered shape, thereby expanding the cardiovascular device.Type: GrantFiled: August 26, 2016Date of Patent: August 25, 2020Assignee: Edwards Lifesciences CorporationInventors: Yidong M. Zhu, PU Zhou, Erik Bulman, Baigui Bian

Patent number: 10751067Abstract: A self-stabilizing pneumatic abdominal aortic tourniquet that utilizes a semi-ridge retaining strap, a ratcheting retaining buckle, and an elastic guide cord on the lower penetrating end of a wedge-shaped bladder. A rigid baseplate is supported by a waist belt having a width identical with the waist belt so that the baseplate provides a stable base for positioning the bladder over a selected area of the patient's abdomen. The air bladder is affixed to the underside of the baseplate, which is initially kept in a deflated condition collapsed against the baseplate, and includes an elastic cord, such as a shock cord, configured to bias the tip of the wedge or “V” shaped bladder in the middle of the baseplate. An air source connected to the air bladder causes inflation and penetration of the lower edge of the bladder into the patient's abdomen thereby causing aorta occlusion.Type: GrantFiled: December 9, 2018Date of Patent: August 25, 2020Assignee: Compression Works, LLCInventors: Richard Schwartz, John M Croushorn
