Publication number: 20210212828Abstract: A mechanism for adjusting the chordae connecting the leaflets of a mitral valve to the papillary muscles in order to restore normal functioning of the mitral valve. The devices or mechanisms can correct problems associated with both prolapsed leaflets and restricted leaflets to allow the leaflets to properly coapt, thereby preventing or minimizing regurgitation. In accordance with the invention, the mechanisms or devices used for adjusting the chordae can be delivered and implanted in a minimally invasive and/or percutaneous manner, such as via transapical methods, transfermoral methods, or trans-septal methods.Type: ApplicationFiled: March 30, 2021Publication date: July 15, 2021Inventors: Niall Duffy, Yueqiang Xue, Luke Hughes

Publication number: 20210069483Abstract: A vascular access device adapter allowing for interchangeable connections between separate components of a larger extravascular system while minimizing exposure to non-sterile environments in point-of-care testing and analysis is provided. The vascular access device adapter includes a body having a self-healing puncturable septum secured by an end cap by which hollow small gauge needles may extract or deposit fluid. The adapter device further includes an end cap enclosing the septum, the end cap having ribs which removably secure the adapter to the inner housing of a sample collection device.Type: ApplicationFiled: August 26, 2020Publication date: March 11, 2021Applicant: Becton, Dickinson and CompanyInventors: Bo Yan, Yueqiang Xue, Xiwei Chen, Jonathan Karl Burkholz

Publication number: 20200384185Abstract: A device to flush a catheter assembly may include a first extension tube and a first connector, which may be coupled to a distal end of the first extension tube. The device may include a second extension tube and a second connector, which may be coupled to a distal end of the second extension tube. The device may include a syringe and an extension, which may be coupled to the syringe. In some embodiments, a first fluid pathway may extend through the first extension tube, and a second fluid pathway may extend through the second extension tube. In some embodiments, a third fluid pathway may extend through the extension. In some embodiments, the third fluid pathway may branch into the first fluid pathway and the second fluid pathway.Type: ApplicationFiled: June 1, 2020Publication date: December 10, 2020Inventors: Lionel Wang, Yueqiang Xue, Bin Dong

Patent number: 9486344Abstract: A bifurcation stent system includes a pair of self-expanding stents. Each stent has a C-shaped body section having a generally semicircular cross-section along its length and an O-shaped body section having a circular cross-section along its length. The stents are deployed in vivo such that the edges of the C-shaped body sections abut each other to form a tubular scaffold in a Y-shaped formation that conforms to the bifurcation. In order to connect the stents in vivo, the C-shaped body sections are configured to include a ball and socket connection there between. The C-shaped body sections align and abut to form a tubular scaffold that extends in the main vessel of the bifurcation, while the O-shaped body sections are tubular scaffolds that extend into the respective branch legs of the bifurcation.Type: GrantFiled: September 15, 2015Date of Patent: November 8, 2016Assignee: Medtronic Vascular, Inc.Inventor: Yueqiang Xue
