Patent number: 10806903Abstract: A handheld vascular access device for gaining access to a patient's vessel includes a hub, a plurality of access needles and a manifold. The hub has an inner wall and side walls that define a plurality of ports. Each of the plurality of ports has a proximal port end and a distal port end. The proximal port ends define a proximal cross-sectional area and the distal port ends define a distal cross-sectional area. The proximal cross-sectional areas are greater than the distal cross-sectional areas. Each of the plurality of ports taper from the proximal port end to the distal port end. The plurality of hollow access needles is arranged along a plane and fixedly coupled to the distal end of the hub. Each of the plurality of needles has a tip. The manifold removably engages the hub at the proximal end of the hub.Type: GrantFiled: June 20, 2017Date of Patent: October 20, 2020Assignee: PRYTIME MEDICAL DEVICES, INC.Inventors: Curtis J.

Publication number: 20200276419Abstract: An access device includes a body, a needle and a guidewire. The body has a guidewire channel extending from a distal end of the body toward the proximal end. The guidewire channel opens into a funnel-like port having a proximal port diameter greater than a distal port diameter. The distal port diameter is substantially the same as a guidewire channel diameter. The needle has a tip, a proximal end and a needle lumen. The proximal end of the needle is removably secured to a distal end of the body in an assembled configuration. A guidewire has a front end portion positioned in the guidewire channel in an initial configuration and a guidewire diameter. The guidewire channel diameter is greater than the guidewire diameter and the guidewire channel facilitates blood flow between the guidewire and an internal surface of the guidewire channel when the guidewire is positioned in the guidewire channel.Type: ApplicationFiled: February 28, 2019Publication date: September 3, 2020Inventors: Curtis J.
