An integrated vascular delivery system and method of use, the system including: a frame having a catheter hub that provides a first anchoring point on the patient and receives a catheter insertable in the patient to transfer fluid at an insertion site, a stabilization hub that provides a second anchoring point on the patient, at least one lateral member extending between the catheter and stabilization hubs, and a fluidic channel. The frame operates in a folded configuration in which the hubs are coupleable and an unfolded configuration in which the anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter. In some embodiments, the system further includes a septum that helps prevent fluid leakage from the catheter hub, or a needle shield that covers the distal end of a needle used during catheter insertion.

A catheter insertion device includes a housing, a needle, a guide wire, and a catheter disposed coaxially over the needle. The needle has a proximal end in the housing and a distal end extending from a distal end of the housing in an insertion position. The guide wire has a distal portion disposed in a lumen of the needle in a withdrawn position. The guide wire may include a safety tip having a non-coiled configuration in the withdrawn position and a coiled configuration in an advanced position. The catheter insertion device may include a sliding member attached to the guide wire, wherein movement of the sliding member translates the guide wire from the withdrawn position to the advanced position.

A catheter assembly includes a catheter; a catheter hub fixed to a proximal end portion of the catheter; a hollow needle having a needle tip and disengageably located in the catheter; a needle hub fixed to a proximal end portion of the needle; a guide wire slidably located in the needle, the guide wire being longer than the catheter and having a distal end that is protrudable from the needle tip; a guide wire hub configured to support the guide wire and move the guide wire with respect to the needle in association with movement of the guide wire hub; and a movement mechanism configured to retract the guide wire hub with respect to the needle hub such that the distal end of the guide wire is housed in the needle in association with forward movement of the catheter hub with respect to the needle hub.

A catheter system may include a catheter assembly and a needle assembly. The catheter assembly may include a catheter hub and a catheter extending distally from the distal end of the catheter hub. The catheter assembly may include a cover coupled to a proximal portion of the catheter hub. The cover may be configured to reduce contact with the catheter assembly during initial insertion of the catheter assembly into vasculature of a patient and/or threading the catheter, which may reduce a risk of bacterial contamination of the catheter. The needle assembly may include an introducer needle, a housing, and a needle hub disposed within the housing. The housing may include a button. A proximal end of the introducer needle may be secured within the needle hub. In response to activation of the button, the needle hub and the introducer needle may move proximally within the housing.

A catheter system may include a blood shield secured within a catheter hub. The blood shield may include a distal end, a proximal end, a blood shield lumen extending through the distal end and the proximal end, and an inner wall forming the blood shield lumen. The inner wall may include a narrowed inner diameter portion or a shield bump. The catheter system may include an introducer needle having a sharp distal tip and a needle bump. The introducer needle may extend through the catheter and the blood shield. In response to proximal retraction of the introducer needle, the needle bump may be configured to contact the narrowed inner diameter portion or the shield bump to pull the blood shield proximally out of the catheter hub. The sharp distal tip may be disposed within the blood shield when the needle bump contacts the narrowed inner diameter portion or the shield bump.

An IV catheter device can include needle cover that functions as a needle shield. By using the needle cover as a needle shield, the design of the IV catheter device is simplified thereby reducing its cost. The needle cover can be configured to slide along a needle hub between a distalmost position in which the needle cover functions as either a needle cover or a needle shield and a proximal position in which the needle cover exposes the needle to enable the catheter to be inserted into a patient's vasculature.

A catheter insertion device for inserting a catheter into a body of a patient is disclosed. The catheter insertion device includes a retractable needle for establishing access to a subcutaneous vessel of the patient and a manually extensible guidewire for guiding the initially attached catheter into the vessel. In one embodiment, the catheter insertion device comprises a housing, a hollow needle retractably extending from the housing, a catheter initially disposed on a portion of the needle, a guidewire including a portion initially disposed within the needle, a guidewire advancement feature configured to selectively advance a distal end of the guidewire distally past a distal end of the needle, and a needle retention component configured to selectively enable retraction of the needle into the housing. The needle retention component is configured to be actuated by the guidewire advancement feature. In one embodiment, one-handed operation of the device is possible.

A catheter system may include a catheter assembly and a needle assembly. The needle assembly may include a cover disposed over a push button. An inner surface of the cover may include a projection, and the cover may be configured to slide proximally. In response to the cover sliding proximally, the projection may be configured to contact the push button, and the push button may be configured to depress. The push button may include a living hinge. The housing may include a flange contacting a proximal end of the push button to prevent the proximal end of the button from being depressed. In response to bending of the living hinge, the push button may be configured to move distal to the flange and depress. In response to depression of the push button, the needle hub may move proximally within the barrel to retract the introducer needle.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A first guide path, a second guide path and a third guide path may be disposed on the housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The retractable sheath also may have a guide element. The first, second and third guide paths are configured to slidingly receive the guide element. The device also having a first locking member, a second locking member, a rotating cam disposed in the housing body, and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection.

Intravenous cannula devices configured to prevent blood backflow and needle prick injuries include a catheter assembly and a needle guard assembly. The catheter assembly includes a hub having a coaxial recess and a valve member positioned therein. The valve member is cylindrical and includes a distal surface having slits collectively defining prongs configured to open and close upon passage of a needle therethrough. Cannula devices configured to prevent needle stick injuries include a safety release component at a distal end of the needle guard assembly. The safety release component includes moveable locking elements configured to fit within an annular groove defined by a proximal portion of the hub upon movement of a needle through the safety release component. Proximal retraction of the needle through the safety release component causes the moveable locking elements to be displaced from the annular groove, thereby decoupling the catheter assembly from the needle guard assembly.
