| 20080200903 | VASCULAR ACCESS DEVICE HOUSING VENTING - A Luer access device may include a housing, a septum, and a gas permeable vent in communication with at least a portion of the housing for venting gas from an extravascular system. A method of venting a medical device may include providing a gas permeable vent within a Luer access device as part of an extravascular system and venting gas from the extravascular system through the gas permeable vent of the Luer access device. | 08-21-2008 |
| 20090012480 | Needle Capture Mechanisms - Needle capture mechanisms and arrangements are provided. One such arrangement includes a needle defining a longitudinal needle axis having a sharp distal tip, a shank portion, and a needle feature defining at least one localized area along the shank of increased outer diameter; a needle shield; and a biasing member adapted to exert a generally downward biasing force upon the needle. Another such arrangement includes a needle defining a longitudinal needle axis having a sharp distal tip, a shank portion, and a needle feature defining at least one localized area along the shank of increased outer diameter; a needle shield, the needle shield comprising a pocket formed therein having an inclined surface; a split collet disposed within the pocket, the split collet having a variable inner bore; and a biasing element disposed within the pocket for biasing the split collet toward the inclined surface of the pocket. | 01-08-2009 |
| 20090312711 | NEEDLE SHIELD AND INTERLOCK - A needle shield system may include a needle, an inner tube, a clip within the inner tube, an outer tube, and/or a housing. A method of shielding a needle may include housing a portion of a needle within a clip, housing the clip within an inner tube, housing the inner tube within an outer tube, housing the outer tube within a housing, interlocking the outer tube and the housing, withdrawing the needle from the clip, trapping a tip of the needle between the clip and the inner tube, partially withdrawing the inner tube from the outer tube, and/or releasing the outer tube and the housing from each other. | 12-17-2009 |
| 20100168675 | ONE PIECE LOW DRAG SEPTUM - A one-piece low drag septum is provided for preventing escape of fluid from an introducer needle during removal of such a needle from a catheter and introducer needle assembly. The septum generally includes a distal portion, a proximal portion, a cavity portion, and a longitudinal axis. The distal portion acts as a primary seal to prevent escape of blood from the catheter into the assembly and is generally positioned furthest away from the user of the apparatus and nearest the patient. The cavity portion reduces friction placed on the introducer needle. The proximal portion of the septum acts as a secondary seal to prevent escape of material from the cavity, seals the cavity, and wipes the needle as it is being withdrawn from the catheter assembly. | 07-01-2010 |
| 20100191188 | Catheter and Introducer Needle Assembly with Needle Shield - A catheter and introducer needle assembly with a needle shield is provided. The needle shield includes a means for preventing unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a means for connecting the needle shield to the catheter hub until the sharp distal tip of the introducer needle has been withdrawn into the needle shield. Thus, when the distal end of the introducer needle extends from the distal portion of the needle shield, the needle shield is connected to the catheter hub and when the sharp distal end of the introducer needle is withdrawn into the needle shield, the needle shield is disconnected from the catheter hub. At that point, the sharp needle tip is secured within the needle shield. | 07-29-2010 |
| 20100191189 | Catheter and Introducer Needle Assembly with Needle Shield - A catheter and introducer needle assembly with a needle shield is provided. The needle shield includes a means for preventing unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a means for connecting the needle shield to the catheter hub until the sharp distal tip of the introducer needle has been withdrawn into the needle shield. Thus, when the distal end of the introducer needle extends from the distal portion of the needle shield, the needle shield is connected to the catheter hub and when the sharp distal end of the introducer needle is withdrawn into the needle shield, the needle shield is disconnected from the catheter hub. At that point, the sharp needle tip is secured within the needle shield. | 07-29-2010 |
