    Abstract: A safety device for a medicine cartridge comprising a body for receiving a cartridge, a guard for covering a used needle, a plunger to dispense medicine from the cartridge and a spring for activation of the guard. The trigger fingers of the guard are spaced to avoid or minimize contact with the spring flange during assembly to avoid trigger finger unseating. An elongated trigger finger head enables the device to activate for all known syringe and syringe plunger tolerances. The spring end coils have larger diameter than the inner coils to reduce the likelihood of the spring end coil end interfering with the cartridge subassembly. Syringe capture features are configured to retain a syringe having a small round or conventional cut flange in place during use and reduce the stress on the syringe flange during insertion while maintaining the ability to hold the syringe in place during use.

  • Patent number: 8617119
    Abstract: A safety device having a tubular support for a needle mount end and a protective shield slidably mounted on the support from a set position, a retracted position and then to a locked position to covers the needle. A locking member mounted on the support, within the shield and a cam follower is engaged with a cam profile on the locking member. Forward axial movement of the support relative to the locking member causes the locking member to rotate relative to the support. The shield has a guide defining a shoulder towards its rearward end and an abutment on the locking member is receivable behind the shoulder when the shield is in its locked position. A spring acts such that when the locking member is turned to engage its abutment with the shoulder of the shield when the latter is in its locked position, so preventing subsequent rearward movement thereof.

  • Patent number: 8568372
    Abstract: 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.

The delivery device may include a base portion and a durable portion connectable to the base portion, and wherein the base portion can be separated from the durable portion and disposed of after one or more specified number of uses. The base portion supports the reservoir and the needle inserter device, while the durable portion supports a drive device for selectively driving the infusion medium out of the reservoir and into the needle and/or cannula.

    Abstract: A plastic needle guard is mounted on a hub in which a needle is secured. In order to cover the end of the needle, the needle guard is slid manually off the hub and over the end of the needle to position the needle end within the guard. A washer that is loosely mounted within the guard and through which the needle passes drops off the end of the needle to block any return movement of the needle out of the guard. Other embodiments use lock-type washers to prevent a return movement of the needle.

    Abstract: A device for injecting fluid from a pre-filled cartridge is provided. The device includes a needle for piercing a patient. After an injection, the needle can be retracted to prevent inadvertent contact with the contaminated needle. A needle retainer releasably retains the needle in the retracted position. The needle can subsequently be re-extended to administer a subsequent injection. After the cartridge is emptied, the cartridge can be removed, if desired, and replaced with another cartridge for additional injections. Alternatively, the needle can be substantially permanently retracted into the device and safely disposed of in a sharps container.

  • Patent number: 6743210
    Abstract: The present invention generally relates to a medical device and procedure for accurately positioning a catheter across a desired region within a patient's vasculature. In particular, the present invention provides a hub assembly unit that allows a physician to precisely position a stent within a vessel utilizing a stent delivery catheter. The hub assembly unit includes a fine adjustment mechanism. The fine adjustment mechanism extends or contracts the length of the hub assembly unit in controlled incremental units. These controlled fine displacements are then translated directly to the stent delivery or balloon dilation catheter.

  • Patent number: 6726712
    Abstract: A prosthesis delivery and deployment device includes an elongated and flexible outer catheter. The outer catheter has a tubular wall of layered construction, including a translucent inner liner running the complete catheter length, and three outer layers including a translucent distal layer, an opaque medial layer and an opaque proximal outer layer. The outer layers are adjacent one another and are bonded to the liner. A braid composed of helically wound metal filaments is disposed between the liner and the proximal and medial outer layers, and includes a distal portion between the liner and a proximal portion of the distal outer layer. The liner and distal outer layer provide a translucent distal region of the catheter that is adapted to constrain a radially self-expanding prosthesis in a radially reduced, axially elongated state. Because the stent constraining region is translucent, an endoscope can be used to visually monitor the stent when so constrained.

    Abstract: A catheter assembly for cannulating a heart vessel includes a guide handle having proximal and distal ends, a lumen open at least at the distal end of the guide handle, and a stop member disposed within the lumen at a distal end of the guide handle. A catheter of the assembly has a proximal end disposed within the lumen of the guide handle and a preformed distal end. The catheter is longitudinally displaceable within the guide handle to adjust an exposed length of the distal end of the catheter. The stop member is engagable with the proximal end of the catheter to prevent the proximal end of the catheter from passing out of the guide handle. A locking mechanism within the guide handle to selectably prevents and permit axial rotation between the guide handle and catheter while permitting longitudinal displacement of the catheter within the guide handle.
