20130253563 | Dilator Centering Device And Assemblies - The present technology is directed to a dilator centering device and assemblies and methods using same. In particular, a dilator centering device in accordance with the disclosed technology can be used with a sheath hub assembly. In one embodiment, a dilator centering device includes a lumen capable of receiving a dilator shaft and centering a dilator shaft with respect to the sheath hub as the dilator shaft enters the sheath hub. In one embodiment, the dilator centering device can be attached to the sheath hub during manufacturing or it can be attached at the use site. In one embodiment, the dilator centering device can be integrated with and non-removable from the sheath hub. The embodiments disclosed herein are illustrative and do not limit the scope and spirit of the disclosed technology. | 09-26-2013 |

20120310213 | Medical Catheter With Bump Tubing Proximal Segment - A medical catheter for inserting into a body includes a bump tubing section with proximal and distal ends, wherein the proximal end is configured to mate with a hub. The bump tubing section has an intermediate portion extending away from the proximal end with a substantially constant outer diameter and thickness, and a taper portion adjacent the distal end with generally decreasing inside and outside diameters to provide a gradually increasing flexibility toward the distal end of the bump tubing section. The bump tubing section is comprised of a polymer having a predetermined flexural modulus. A tip section is disposed distally of the distal end of the bump tubing section comprising a distal liner and a distal cover such that at least a majority of the tip section has a substantially constant stiffness and a flexural modulus substantially equal to or greater than the predetermined flexural modulus. | 12-06-2012 |
20120238956 | Microaccess Kit Comprising A Tapered Needle - The present technology is directed to introducer needle assemblies comprising a tapered needle; as well as to kits comprising a tapered needle, a guidewire and a dilator and sheath; as well as to methods of introducing a dilator to the interior of a patient's body as part of an interventional procedure. | 09-20-2012 |
20110202035 | Syringe Assemblies Having Detachable Needle Assemblies and Low Dead Space - The present invention is directed to syringe assemblies comprising detachable needle assemblies, that are configured in such a manner as to minimize the dead space after deployment of the syringe piston and injection of the material in the syringe into a patient's body, as well as with bevel indicators that provide guidance as to optimal angles at which to inject the needles into patients. | 08-18-2011 |
20110178471 | Kits Comprising Syringe Assemblies - The present invention is directed to kits comprising syringe assemblies having detachable needle assemblies, as well as shield apparatuses to protect the needle assemblies. The syringe assemblies are configured to minimize the dead space after deployment of the syringe and injection of the material in the syringe into a patient's body, as well as to include detachable needle assemblies, such that different needle assemblies can be interchanged on a single syringe barrel. | 07-21-2011 |
20110092952 | Shield Apparatuses and Methods For Storing Syringe Assemblies and Needle Assemblies - The present invention is directed to shield apparatuses configured to hold syringe assemblies in a manner that preserves their ease of use and convenience. In some embodiments, the syringe assemblies are detachable, and the shield apparatuses provide for convenient interchanging of the needle assemblies, as well as methods for administering injections to a patient. | 04-21-2011 |
20100087784 | Safety Needle Assembly - A safety needle assembly comprises a cannula holding member, a cannula fixed to the cannula holding member, and a safety device mounted on the cannula holding member. The cannula holding member includes one or more outwardly directed fins extending longitudinally along at least a portion of the cannula holding member. The safety device includes a collar adapted to be mounted on the cannula holding member and a sheath. The sheath possesses an interior bounded by a back wall and a pair of oppositely positioned side walls, and also includes an opening positioned opposite the back wall. The sheath is also provided with at least one fin engaging member connected to the back wall and extending from the back wall in a direction toward the opening. The fin engaging member is spaced from the side walls of the sheath. The sheath is pivotally connected to the collar to pivot in a closing direction toward the cannula so that during pivoting of the sheath in the closing direction the cannula passes through the opening in the sheath and is positioned in the interior of the sheath to be covered by the sheath, with the distal end portion of the at least one fin engaging member automatically engaging at least one of the fins on the cannula holding member when the cannula is positioned within the interior of the sheath to lock the sheath relative to the cannula holding member to prevent the sheath from being pivoted away from the cannula. | 04-08-2010 |
20100076384 | Detachable And Freely Rotating Hemostasis Valve - The present invention is directed to a valve hub comprising a hemostasis valve enclosed within a housing, the housing having an upper portion and a lower portion and an access port aligned with the vertical axis of the hemostasis valve; wherein the lower portion of valve hub is engaged within a connector such as a luer fitting, such that the valve hub rotates freely about its vertical axis. The present invention is also directed to medical devices comprising such valves hubs and catheters, as well as methods for assembling such devices and performing medical procedures using such devices. | 03-25-2010 |
20090312786 | Guide Sheath Dilator And Method Of Using The Same - The present invention relates to a dilator. The dilator includes a shaft, a lumen and a hub. The shaft has at least two stiffness sections with the stiffness sections becoming less rigid as they approach a distal end of the shaft. The varying stiffness sections allow the dilator to track along the guidewire through torturous vasculature so as the dilator is advanced and the stiffness is changed, the stiffer sheath can advance smoothly through a blood vessel. The dilator may also taper at the distal tip to stretch the initial skin puncture hole larger to accommodate the dilator shaft and ease the sheath tip insertion through to the vasculature. Or the shaft may taper from where it extends beyond the sheath distal tip to the distal end so that it can reach further distal in the vasculature. The dilator may also include an atraumatic tip for easier advancement of the dilator. The dilator distal end may also include one or more radiopaque markers and a shaped distal end. | 12-17-2009 |
