Patent number: 8568372Abstract: A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.Type: GrantFiled: December 14, 2012Date of Patent: October 29, 2013Assignee: B.

Publication number: 20130102976Abstract: A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub.

In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.Type: ApplicationFiled: December 14, 2012Publication date: April 25, 2013Applicant: B.Braun Melsungen AGInventor: B.

Patent number: 8414539Abstract: A needle tip protective device for use with percutaneous entry needles. In one embodiment, the needle tip protective device includes a needle guard slidably mounted on a hypodermic needle, the latter having a needle tip located at the distal end thereof, and a change of profile formed medially there along. The needle guard is movable along the hypodermic needle and engageable with the change in profile formed thereon. The engagement with the change in profile is configured to correspond with the ability of the needle trap to entrap the needle tip once the needle trap has advanced the sufficient distance distally along the hypodermic needle. In further refinements, the needle trap may be biased toward the distal needle tip of the needle.Type: GrantFiled: December 27, 2011Date of Patent: April 9, 2013Assignee: B.

Patent number: 8403886Abstract: A needle guard includes a clip with a canting wall to grip the needle shaft and a distal wall to block the tip thereof, wherein the canting and distal walls may be interconnected by an angled strut, a spring member, such as a leaf spring, may have a portion extending past an edge of the strut to bias the clip to grip the needle shaft, and the distal wall may be or include a stylus and have an L-shape to define a lip to help block the needle tip. The clip may have a depending heel to help pivot the clip about a ledge to grip the needle shaft. A needle support may be provided to limit flexure of the needle which might otherwise allow the needle to come loose from the clip. Arrangements for limiting rotation of the needle hub and needle guard housing are provided, as is a protective shroud to reduce the risk of inadvertent activation of the needle guard. Further, the needle guard may be used with a catheter assembly. Also provided is an improved duckbill release mechanism.Type: GrantFiled: August 8, 2005Date of Patent: March 26, 2013Assignee: Smiths Medical ASD, Inc.Inventors: Dennis M Bialecki, Sean J Albert, Thomas K Sutton

Patent number: 8382721Abstract: A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.Type: GrantFiled: December 5, 2011Date of Patent: February 26, 2013Assignee: B.

Publication number: 20130046253Abstract: Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.Type: ApplicationFiled: October 22, 2012Publication date: February 21, 2013Applicant: MEDTRONIC MINIMED, INC.Inventor: MEDTRONIC MINIMED, INC.

Patent number: 8372044Abstract: The present invention provides an injection device including a syringe having a distal end for receiving a needle, and a plunger inserted into a proximal end. A guard is slidable on the syringe, has a proximal end, a distal end, and is biased from a first position wherein the needle is exposed toward a second position wherein the guard covers the needle. The syringe includes a body having a central cylindrical opening for receiving a medicine and the plunger, and further includes a pair of longitudinally extending members on opposite sides of the body. The injection device includes cooperating detents for retaining the guard and syringe in the first and second positions. A latch member is engageable by the plunger as the plunger is depressed to release the cooperating detents. Upon release, a spring element biases the guard toward the second position.Type: GrantFiled: May 20, 2005Date of Patent: February 12, 2013Assignee: Safety Syringes, Inc.Inventors: Lars Tommy Westbye, Philip Dowds

Patent number: 8361039Abstract: A system is provided for performing injections in the ventricle of a patient. The system includes an injection catheter with a proximal and distal end. Importantly, a flexible array is mounted at the distal end of the injection catheter and is moveable between a protective configuration and a flared configuration. Also, a needle of variable length is mounted on the distal end of the injection catheter and is covered by the flexible array when the array is in its protective configuration. In order to manipulate the flexible array, a locking mechanism is mounted on the proximal end of the injection catheter for engagement with the flexible array. When selectively operated, the locking mechanism moves the array from its protective configuration to the flared configuration, holds the array in its flared configuration for an injection, and subsequently moves the array back to its protective configuration.Type: GrantFiled: January 26, 2009Date of Patent: January 29, 2013Inventor: Richard A.
