Patent number: 11525670Abstract: Shape-sensing systems and methods for medical devices. The shape-sensing system can include a medical device, an optical interrogator, a console, and a display screen. The medical device can include an integrated optical-fiber stylet having fiber Bragg grating (“FBG”) sensors along at least a distal-end portion thereof. The optical interrogator can be configured to send input optical signals into the optical-fiber stylet and receive FBG sensor-reflected optical signals therefrom. The console can be configured to convert the reflected optical signals with the aid of filtering algorithms of some optical signal-converter algorithms into plottable data for displaying plots thereof on the display screen. The plots can include a plot of curvature vs. time for each FBG sensor of a selection of the FBG sensors for identifying a distinctive change in strain of the optical-fiber stylet as a tip of the medical device is advanced into a superior vena cava of a patient.Type: GrantFiled: November 25, 2020Date of Patent: December 13, 2022Assignee: Bard Access Systems, Inc.Inventors: Shayne Messerly, Anthony K.

Patent number: 11517719Abstract: A catheter assembly includes a peripheral intravenous (“PIV”) portion that provides expedited vascular access. The catheter assembly includes an elongate catheter body defining a first lumen and includes a CVC portion, a transition portion, and a PIV portion. The PIV portion defines a relatively smaller diameter, a tapered tip, and a lumen configured to receive a needle. The needle extends through a needle access aperture, disposed through a side wall of the catheter body, through the PIV lumen, to a point beyond a distal end of the catheter body. A clinician accesses a vasculature using the needle and the PIV portion. The needle is then removed and a guidewire advanced through the lumen of the catheter body and the PIV portion into the vasculature. The CVC portion is then advanced over the guidewire into the vasculature, self-dilating the insertion site as the transition portion enters the vasculature.Type: GrantFiled: September 24, 2020Date of Patent: December 6, 2022Assignee: Bard Access Systems, Inc.Inventor: Glade H.
