Patent number: 11219708Abstract: In some examples, a device, which may be used to access vasculature or another hollow anatomical structure of a patient, includes a housing, a cannula mechanically coupled to a housing distal end, and a needle configured to be locked in a deployed configuration in which the needle extends within a cannula lumen and protrudes from the cannula distal end. The needle is configured to slide proximally through the cannula lumen from the deployed configuration into a retracted configuration in which at least a portion of the needle is within a housing lumen. The device further includes at least one needle guide configured to maintain the needle along a path in the housing lumen substantially parallel to the needle guide when the needle moves between the deployed configuration and the retracted configuration.Type: GrantFiled: February 8, 2019Date of Patent: January 11, 2022Assignee: COVIDIEN LPInventor: Les Hull
