Publication number: 20230103258Abstract: The device disclosed herein is used to the remove a thrombus from the vasculature. It includes an aspiration catheter and a thrombus retrieval device that extends through the lumen of the aspiration catheter. An expandable braided assembly extends over a distal region of the retrieval device, and an activation wire extends through the lumen of the retrieval device to attach to and control the expansion of the braided assembly. Applying tension to the activation wire causes the braided assembly to expand to a diameter of the practitioner's choosing. For example, the practitioner may apply a first level of tension to the activation wire to deploy the braided assembly to a first diameter and then later change the diameter by applying a different level of tension. The expanded braided assembly contacts the thrombus and is pulled proximally toward the aspiration catheter to assist in thrombus removal.Type: ApplicationFiled: November 1, 2022Publication date: March 30, 2023Inventors: Ravish Sachar, Eugene Serina, Hung Ha, Dave Stern

Publication number: 20220079760Abstract: Annuloplasty implant systems and methods of deployment within a catheter-based procedure are provided herein. Such systems can utilize annuloplasty rings defined by a scaffold of braided wire that is radially expandable and axially collapsible or by annuloplasty rings defined by multiple interconnected concentric loops. The rings can be formed of a memory alloy and expand to an implantation configuration when advanced from the catheter to be secured against the valve annulus with the anchors. Deployment systems can include delivery catheters that deploy multiple anchors about a valve annulus, and advance the annuloplasty ring over multiple torque wires to securely couple the ring with the anchors forming the annuloplasty ring thereby reforming the valve annulus.Type: ApplicationFiled: September 14, 2021Publication date: March 17, 2022Applicant: Bluesail New Valve Technology Asia Ltd.Inventors: Eugene Serina, Minh Nguyen, Sherrie Yang, Yen Thai

Publication number: 20220079762Abstract: Anchor deployment systems and methods, particularly for deployment of annuloplasty implant systems in a catheter-based procedure, are provided herein. Such systems can include a double-basket structure having expandable centering structure and outer anchor support frame disposed over at least over a proximal portion of the centering structure. The structures can be advanced together as an assembly. Subsequent expansion of the centering structure centers the assembly within the valve annulus while the anchor support frame positions the anchors at suitable positions around the valve annulus. The centering member can be contracted and withdrawn into the catheter to allow normal valve function, while the anchors remain supported by the anchor support frame for deployment by the clinician and implantation into surrounding tissue. The delivery catheter can include a proximal handle with various control features including selectors to allow selective implantation of all or any combination of anchors concurrently.Type: ApplicationFiled: September 14, 2021Publication date: March 17, 2022Applicant: Bluesail New Valve Technology Asia Ltd.Inventors: Eugene Serina, Minh Nguyen, Sherrie Yang

Patent number: 10835722Abstract: The present disclosure describes an angioplasty balloon catheter having a retractable sheath and a flexible tip attached to the distal end of the sheath. The flexible tip is made of an elastomeric plastic that is capable of returning to its original shape after being expanded multiple times. The tip allows for the sheath to be retractable and the balloon inflated multiple times to treat or expand different locations within the vessel. Because the tip returns to its original shape each time, the tip is less likely to damage the vessel wall when the sheath is repositioned in the vessel, and also is easier to retract through a guide-catheter.Type: GrantFiled: November 28, 2018Date of Patent: November 17, 2020Assignee: Biosensors International Group, Ltd.Inventors: Roseann Ward, Eugene Serina, Emilio Crisolo
