Patent number: 8915884Abstract: An access device places a medical article within a body space of a patient. The device has a needle section that includes an elongated body and a needle hub. The device further includes a dilator portion that has a dilator and a dilator hub. The dilator is coaxially disposed and slideable over the elongated body of the needle section. The device further includes a sheath section that has a sheath and a sheath hub. The sheath is coaxially disposed and slideable over the dilator. The device further includes a first locking mechanism operably disposed between the needle hub and the dilator hub to inhibit at least unintentional axial movement between the needle section and the dilator portion and a second locking mechanism operably disposed between the dilator hub and the sheath hub to inhibit at least unintentional axial movement between the dilator portion and the sheath section.Type: GrantFiled: January 22, 2013Date of Patent: December 23, 2014Assignee: Access Scientific, Inc.Inventors: Michael Tal, Janelle Anderson, Benjamin K Yaffe, William J McCreight, Robert Rabiner, V

Patent number: 8202251Abstract: An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The device further includes a dilator and a medical article. A track can extend in a proximal direction from the dilator. The needle hub can slide along at least a portion of the track between a first position and a second position. The device can further include a locking mechanism operably disposed between the track and the needle hub so as to inhibit further axial movement of the needle in the proximal direction when the needle hub is in the second position. The device can further include a guidwire that can bend such that the guidewire can both pass through the needle hub at one end and attach to the needle hub at another end.Type: GrantFiled: March 13, 2009Date of Patent: June 19, 2012Assignee: Access Scientific, Inc.Inventors: Steven F. Bierman, Richard A. Pluth

Patent number: 8192402Abstract: An access device places a medical article within a body space of a patient. The device has a needle that includes a needle body and hub. The device further includes a dilator coaxially disposed and slideable over the needle body and a medical article. A viewing space is disposed between the dilator and the medical article with at least one passageway or conduit connecting the viewing space with the interior bore of the needle body. The passageway is defined at least in part by openings through the sides of the needle and dilator. At least a portion of the conduit or passageway can be defined by one or more grooves between the needle and dilator. The device can further include a guidewire and an interlock between the guidewire and the needle and/or dilator. The device can further include one or more stops disposed between the guidewire and the needle and/or dilator to limit the extent to which the guidewire can be moved (e.g., advanced) relative to the needle or inhibit such relative movement (e.g.Type: GrantFiled: April 18, 2008Date of Patent: June 5, 2012Assignee: Access Scientific, Inc.Inventors: Janelle Anderson, Michael Tal, Steven F.
