Abstract: A vascular access device includes an interior chamber for receiving a fluid and a filter within the interior chamber for filtering a pathogen within the fluid. A method of filtering a pathogen in a vascular access device includes providing a vascular access device having an interior chamber for receiving a fluid, providing a filter within the interior chamber of the vascular access device to move the fluid through the filter, and filtering a pathogen as the fluid moves through the filter.

Abstract: A medical device includes a body and an interior surface of the body that communicates with a fluid capable of delivering a pathogen to the interior surface. The medical device may also have an energy source coupled with the vascular access device that provides energy to the interior surface of the body to repress pathogenic activity. A method of repressing pathogenic activity in a vascular access device includes providing a body having an interior surface and energizing the vascular access device to repress pathogenic activity on the interior surface.

Abstract: A needle shield assembly with a needle having a distal tip and a static feature is provided. The needle shield assembly includes an adapter having an open distal terminus and an open proximal terminus to allow passage of the needle and a needle shield slidably associated with the adapter having an open distal end and an open proximal end where the open proximal end is sufficiently narrow to restrict proximal movement of the needle static feature causing the shield to move in a proximal direction when the needle is pulled proximally after the static feature has established contact with the needle shield proximal end. The assembly includes a canting plate having an unactivated first position and an activated second position that restricts needle movement. The canting plate is activated via a canting plate retention system in communication with the canting plate and responsive to proximal movement of the needle.

Abstract: 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 The needle shield includes a means for preventing unwanted distal movement of the needle once the needle has been withdrawn into the needle shield.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means for connecting the needle shield to the catheter hub until the sharp distal tip of the introducer needle has been withdrawn into the needle shield.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.

Abstract: A vascular access device having a spring-biased septum is provided for preventing the leakage of blood during the placement and use of vascular catheters and similar devices. The structure of the device includes a housing with an internal channel. A spring-biased septum is placed securely within the channel such that it substantially blocks blood flow through the channel. The spring-biased septum includes an elastic plug having a pre-slit or pre-molded hole and a biasing element disposed about the elastic plug. A needle or other object may be withdrawn through the slit or hole, after which the biasing element forces the hole closed, preventing blood leakage.

Abstract: A catheter and introducer needle assembly with a compact needle shield is provided wherein the needle includes a discontinuity thereon, which may take the form of an enlarged diameter portion. The needle shield includes a spring clip that engages the enlarged diameter portion to prevent unwanted proximal and distal movement of the needle once the needle has been withdrawn into the needle shield.

Abstract: A shielded surgical scalpel includes an elongate handle defining a longitudinal axis and having a proximal portion and a distal portion. A blade is fixedly attached to the handle. A shield is mounted onto the handle. The shield is movable between a distal position where the shield prevents inadvertent access to the blade and a proximal position where the shield exposes the blade for use.

Abstract: An adapter is provided that allows a single introducer needle assembly having a male luer portion at its distal end to be used with a device having a female luer portion at its proximal end, such as a catheter, and a device without such a female luer portion, such as a catheter introducer.

Abstract: A catheter and introducer needle assembly with needle shield is provided wherein the needle includes an enlarged diameter portion and a distally facing shoulder. The needle shield includes a means for engaging the distally facing shoulder to prevent unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a small diameter opening adjacent to its proximal portion to limit proximal movement of the needle out of the needle shield.

Abstract: A catheter introducer is disclosed having a splittable introducer and an introducer needle. The splittable introducer includes a pair of wings and a tray with an open top extending from the proximal end of the introducer cannula between the wings to lead the distal end of a long, thin and flexible medical device into the open proximal end of the splittable introducer cannula.

Abstract: A sheath lock for use with a splittable sheath is disclosed. The sheath lock includes a tapered slot extending from a wide untapered end to a narrow tapered end. A lock box is located adjacent the narrow tapered end of the tapered slot. The lock box has a plurality of tines which grip and retain the sheath when it is positioned within the lock box. The sheath can freely move through the wide untapered end, but the sheath is securely locked when it is moved through the tapered slot from the untapered end into the lock box. The plurality of tines can be arranged in various configurations to form the lock box, including elliptical, circular, rectangular or square configurations around the lock box.

Abstract: A winged catheter introducer for use in introducing a catheter into a blood vessel is disclosed. A needle is disposed within the catheter to help penetrate a patient's blood vessel. The needle and catheter are disposed within an introducer body having a pair of deformable wings extending from opposite sides of the body. A pair of opposing clamp jaws are disposed within the introducer body adjacent the wings. The clamp jaws are configured to grip and retain the catheter and needle when the wings are compressed towards each other. In a disclosed embodiment, the clamp jaws are biased in an open configuration and define clamp surfaces having angled ridges which engage the catheter exterior surface.
