摘要： A catheter insertion device includes a housing, a needle, a catheter, and a guide wire. The needle has a proximal end positioned in the housing and a distal end extending beyond a distal end of the housing. The catheter is positioned coaxially over the needle, and includes a flexible tube and a catheter hub on a proximal end of the flexible tube. A proximal portion of the flexible tube and the catheter hub are positioned in the housing. The guide wire has a proximal end positioned in the housing and a distal end positioned in a lumen of the needle. The catheter insertion device also includes a handle coupled to the catheter, wherein movement of the handle relative to the housing moves the catheter hub from a position in the housing to a position outside of the housing.

摘要： Devices and methods for guidewire assisted placement of catheters into blood vessels are described. Some of the devices and methods relate to automated or partially automated or assisted insertion and placement of an intravenous catheter into a vein or artery of a patient. Other of the devices are blood draw devices and methods for insertion and placement of an intravenous device into a vein or artery of a patient or to withdraw a blood sample from the patient. The devices also provide for guide wire tip inspection after use.

摘要： Intravenous access is achieved by introducing a catheter over an access needle which is initially present in the catheter. A tapered dilating element is positioned over the needle and provides a transition between the needle and a larger catheter lumen. The access needle is hollow and has a port which allows blood to flash back through a lumen of the catheter so that flashback can be observed on a catheter hub or the catheter itself.

摘要： Intravenous access is achieved by introducing a catheter having a guidewire safety tip at its distal end. The safety tip can be advanced and retracted using a slider disposed over an access needle which is initially present in the catheter. After the catheter has been properly positioned, the access needle and guidewire may be removed so that the catheter is available for use.

摘要： 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 The guide wire has a distal portion disposed in a lumen of the needle in a withdrawn position.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.

摘要： A catheter insertion device and method for insertion. The catheter insertion device can include a housing, a needle attached to a needle carrier, a catheter including a catheter shaft attached to a catheter hub, and a guidewire. The guidewire can include a coil tip positioned in a lumen of the needle. The method for insertion can include inserting a distal end of the needle and the catheter shaft into a blood vessel of a patient, advancing the coil tip out of the needle lumen and into the blood vessel, advancing the catheter over the guidewire, and withdrawing the guidewire and the needle from the catheter. The coil tip can include a straightened configuration and a coiled configuration. The coil tip can transition from the straightened configuration in the needle lumen to the coiled configuration in the blood vessel.

摘要： A method for treating a patient using a catheter insertion device. The catheter insertion device includes a housing, a needle, a catheter, a guidewire, and an actuator mechanism. The needle is attached to a needle carrier, the catheter is positioned coaxially around the needle such that a distal end of the needle extends distal of a distal end of the catheter, and the guidewire has a distal end positioned in a lumen of the needle. The method includes holding the catheter insertion device, inserting the distal end of the needle and catheter into a blood vessel, advancing the distal end of the guidewire out of the lumen of the needle into the blood vessel, moving the catheter over the guidewire in the blood vessel, and activating the actuator mechanism to simultaneously retract the distal end of the needle and the distal end of the guidewire into the housing.
