Publication number: 20220225975Abstract: A sealant is provided for sealing a puncture through tissue that includes an elongate first section including a proximal end, a distal end, and a cross-section sized for delivery into a puncture through tissue, and a second section fused to and extending from the distal end of the first section. The first section may be formed from a freeze-dried hydrogel that expands when exposed to physiological fluid within a puncture. The second section may be formed from a solid mass of non-freeze-dried, non-crosslinked hydrogel precursors, the precursors remaining in an unreactive state until exposed to an aqueous physiological, whereupon the precursors undergo in-situ crosslinking with one another to provide an adhesive layer bonded to the first section. Apparatus and methods for delivering the sealant into a puncture through tissue are also provided.Type: ApplicationFiled: August 30, 2021Publication date: July 21, 2022Inventors: Andy H. UCHIDA, Anthony P. SPIZUOCO, Kevin TO, Florencia LIM, Scott R. SERSHEN

Patent number: 11305040Abstract: Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy. For example, the dialysis systems include disposable cartridge and patient tubing sets that are easily installed on the dialysis system and automatically align the tubing set, sensors, venous drip chamber, and other features with the corresponding components on the dialysis system. Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.Type: GrantFiled: August 7, 2015Date of Patent: April 19, 2022Assignee: Outset Medical, Inc.Inventors: Michael Edward Hogard, Gopi Lingam, Dean Hu, Balaji M.

Publication number: 20220022916Abstract: An anti-hemorrhaging device includes an elongate body, a flexible looped segment, a shield, and an inflatable seal. The elongate body is configured to attach to a vacuum source. The flexible looped segment is attached to the elongate body includes a plurality of holes on an inner circumference thereof. The flexible looped segment is configured to be placed in a uterus. Activation of the vacuum source is configured to pull vacuum through the plurality of holes so as to collapse the uterus upon insertion of the elongate body into the uterus. The shield is folded around an exterior circumference of the looped portion and has edges that extend radially inwards relative to the flexible looped distal section. The shield is configured to prevent tissue from occluding the plurality of holes when vacuum is applied. The inflatable seal is attached to the elongate body and is configured to seal the uterus.Type: ApplicationFiled: December 10, 2019Publication date: January 27, 2022Applicant: ALYDIA HEALTH, INC.Inventors: Andy H.

Patent number: 9532785Abstract: Methods and devices for maintaining vascular access and/or minimizing bleeding during percutaneous interventions. The method can include advancing an access wire through a previously placed access catheter in a contralateral femoral artery to position an inflatable balloon on the access wire in a vascular access sheath located in an ipsilateral femoral artery, without using any additional guidewires to advance the access wire. After withdrawing the vascular access sheath at least partway out of the ipsilateral femoral artery to expose the vascular injury, the balloon can be inflated to occlude the ipsilateral femoral artery or an ipsilateral iliofemoral artery at or near the vascular injury.Type: GrantFiled: May 8, 2013Date of Patent: January 3, 2017Assignee: Access Closure, Inc.Inventors: Ali Hassan, Kevin To, Andy H.
