A vascular access system comprises a needle having a distal tip and a proximal fitting section and a dilator having a solid distal section connected to a solid proximal section and an annular recess therebetween, the dilator having a passageway so that the dilator is coaxially positioned around the needle. The needle has at least one opening positioned proximal to its distal tip so that, when the distal end of the needle enters a blood vessel, blood enters the annular recess to show the operator that access has been achieved. Optionally, a sheath having a distal tip, a proximal fitting section, and a lumen sufficient to coaxially fit over the dilator.

The invention relates to the guidance, positioning and placement confirmation of intravascular devices, such as catheters, stylets, guidewires and other flexible elongate bodies that are typically inserted percutaneously into the venous or arterial vasculature. Currently these goals are achieved using x-ray imaging and in some cases ultrasound imaging. This invention provides a method to substantially reduce the need for imaging related to placing an intravascular catheter or other device. Reduced imaging needs also reduce the amount of radiation that patients are subjected to, reduce the time required for the procedure, and decrease the cost of the procedure by reducing the time needed in the radiology department. An aspect of the invention includes, for example, an endovenous access and guidance system. The system comprises: an elongate flexible member adapted and configured to access the venous vasculature of a patient; a sensor disposed at a distal end of the elongate flexible member and configured to provide in vivo non-image based ultrasound information of the venous vasculature of the patient; a processor configured to receive and process in vivo non-image based ultrasound information of the venous vasculature of the patient provided by the sensor and to provide position information regarding the position of the distal end of the elongate flexible member within the venous vasculature of the patient; and an output device adapted to output the position information from the processor.

A vascular access device and method of using is disclosed. The vascular access device includes a housing defining a cavity and adapted to connect to a catheter. A self-sealing injection port and a subhousing are also provided. The subhousing may be movably connected to the housing so that a position of the other end of the subhousing relative to the housing can be selectively adjusted within a range of positions. A unidirectional fluid valve permits solution flow from the subhousing to the housing. The vascular access device may be utilized in a variety of treatment protocols including medication administration, fluid sampling, and placement of balloon catheters or guide wire-based medical devices.

Vascular access devices and methods of use may utilize a single access port which is attached to a vessel wall and allows for controlled insertion of small to large sized instruments and catheters. The access port may be secured via securement mechanisms deployed from within the vessel lumen. Also, one or more cutting blades may be utilized to create and / or define the individual flaps in the access port and / or underlying tissue wall at the time of port deployment and securement. Such an access port allows a user to access and / or re-access the same artery and / or vein of patients utilizing various diameter catheters and instruments while maintaining hemostasis.

A vascular access device may include a septum and a gas permeable vent in communication with at least a portion of the septum. The vent may be capable of venting gas from an extravascular system to which the vascular access device is capable of attaching. A method of venting a medical device may include providing a vascular access device having a septum and forming part of an extravascular system, providing a gas permeable vent in communication with at least a portion of the septum, and venting gas from the extravascular system through the gas permeable vent of the device.

Featured is a vascular access device such as an IV catheter device including a housing, a tubular member, a seal member, a compression member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal housings. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also forms a septum, which is compressed by the compression member to prevent seepage upon removal of a stylet.

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.

A vascular access device may include a body and a layer of the body that communicates with a pathogenic environment to discourage adhesion of a pathogen to the layer and thus repress pathogenic activity. A method of repressing pathogenic activity in a vascular access device includes providing the device with a body, and coating the body with a layer that discourages adhesion of a pathogen to the layer.

A vascular access device incorporating a luer integrated air venting system, including a female luer fitting having a venting mechanism located within the female luer fitting and a fluid diverter located within the vent mechanism. The venting mechanism providing communication between said vascular access device and ambient surroundings until contact with a fluid.
