A catheter package includes an elongated case. A cap is attached to the case by a flexible strap. The case receives the tubing portion of a catheter. The catheter has a funnel attached to the tubing. The funnel has a seal portion releasably engageable with the case. The cap is releasably engageable with the funnel to retain the funnel in contact with the case. A user can flip the cap off the funnel to permit removal of the catheter from the case. The funnel may include ridges or a tactile ring to improve the user's grip on the funnel. An adaptor may be disposed between the funnel and case to allow mating of different cross sectional shapes of the funnel and case. A hydration device may be inserted in the case. Alternately, a tubular liner may be inserted in the case to separate liquid water on the outside of the liner from the catheter tubing on the inside of the liner. A window in the liner mounts a patch of filter material that permits the passage of water vapor into the interior of the liner.

A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.

Disclosed herein are vascular access systems and methods thereof. For example, a vascular access system includes a port configured for subdermal implantation and a single-use access device. The port can include a port hub and a catheter tube. The port hub can include an access funnel and a septum defining a pair of port-hub lumens. The catheter tube can include a septum defining a pair of catheter-tube lumens fluidly coupled to the pair of port-hub lumens. The access device can include a bifurcated hub and a pair of cannulas. The pair of cannulas defines a pair of cannula lumens coupled to a pair of access device-hub lumens of the bifurcated hub. The pair of cannulas can be configured to simultaneously insert into the access funnel and couple the pair of cannula lumens to the pair of catheter-tube lumens when the pair of cannulas is fully seated in the port hub.

A catheter is configured to reduce a possibility that a shaft of a catheter inserted into a body comes off from a hub on a proximal side when a contrast agent is injected at a high pressure and the shaft is pulled out. The catheter includes a shaft and a hub that are directly fusion-bonded at a shaft accommodation portion of the hub that accommodates a proximal end of the shaft and a vicinity of the proximal end and a minimum inner diameter of the shaft accommodation portion is at any portion of the fusion surface. The shaft is thus prevented from coming off from the hub, safety of a worker is achieved without using an adhesive, a yield is further improved, and a manufacturing cost and a cost required for ensuring safety are reduced.

Disclosed herein are impedance-determining medical systems. An impedance-determining medical system can include an impedance interrogator and an impedance-sensing medical device. The impedance interrogator can include instructions configured to instantiate one or more processes in random-access memory upon processing by one or more processors that determine impedance from electrical signals corresponding to electrical currents passed through a biological or non-biological material. The impedance-sensing medical device can include two or more longitudinal conductors distributed among one or more pieces of the impedance-sensing medical device and separated by one or more longitudinal insulators. The two-or-more conductors can be configured to emit, detect, or alternately emit and detect via two or more electrodes thereof the electrical currents passed through the biological or non-biological material. The impedance-sensing medical device can be configured to form a direct or indirect connection to the impedance interrogator and provide the electrical signals to the impedance interrogator.

The present disclosure is a blood collection assembly that has a needle assembly fixedly coupled to a finger-activated actuator and tubing and the needle assembly has a needle. Further, the blood collection assembly has a hub that houses the needle assembly and the hub has a channel in a top surface of the hub. Additionally, the channel slidably engages the finger-activated actuator such that when the finger-activated actuator is moved from a distal end of the hub to a proximal end of the hub the needle retracts within the hub.

A system for delivering an agent including a plurality of particles to a target site. The system incudes a catheter having a first wall defining an inner lumen for delivery of the agent to the target site, and a second wall surrounding the first wall to define an outer lumen therebetween for delivery of a fluid to the target site. The catheter has a distal end terminating with a primary opening of the inner lumen and a secondary opening of the outer lumen. A hub associated with a proximal end of the catheter includes a first inlet for receiving a supply of the agent and a second inlet for receiving a supply of the fluid, wherein the first inlet is in fluid communication with the inner lumen, and the second inlet is in fluid communication with the outer lumen.

Disclosed herein are methods to restore myocardial conduction via the injection of conductive nanoparticles into the myocardium via an endovascular injection catheter.

An apparatus comprising a catheter tube; a hub having a distal section joined to the catheter tube and a proximal section defining a housing; at least one port connected to the hub by a fluid passage through a passageway; a needle extending through the hub and the catheter tube, wherein the needle has opposite proximal and distal ends, the distal end forming a needle tip; a needle hub attached to the proximal end of the needle; a needle guard slidably arranged on the needle, wherein the needle guard is movably retained in the housing of the hub when the needle extends through the hub and the catheter tube, wherein the needle guard is removable from the hub once the needle tip is received in the needle guard upon withdrawal of the needle from the catheter tube; and wherein the hub is made of two parts each having distal and proximal end sections.

A system and method for delivering a medicament including a catheter configured for implantation in different target tissue sites, extending from a proximal end to a distal end, and having a sidewall which defines an internal lumen. The distal end has one or more apertures in the sidewall for the release of the medicament into the target tissue site; the system also comprises a medicament reservoir fluidly communicable with the internal lumen of each catheter, an adhesive member configured to adhere to the skin of the patient around the exit wound and having an opening therein to allow the catheters to pass through the adhesive member and a retaining member configured to be overlaid on the adhesive member and comprising a guide surface configured to receive a length of the two or more catheters and a plurality of retaining portions to retain the catheters against the guide surface.
