An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.

An infusion base for attachment to a user of an infusion set comprises an adapter having a lower portion, an inner wall portion, and a gap between the lower portion and the inner wall portion. At least one of the lower portion and the inner wall portion is configured to receive an attachment.

A user-initiated fluid pathway connection includes: a connection hub, a piercing member, a sterile sleeve, and a drug container having a cap, a pierceable seal, a barrel, and a plunger seal, wherein the piercing member is initially retained within the sterile sleeve between the connection hub and the pierceable seal of the drug container. The connection hub may include an internal aperture within the connection hub which functions as a flow restrictor and wherein a piercing member is connected to one end of the internal aperture and a fluid conduit is connected to another end of the internal aperture. A drug delivery pump with integrated sterility maintenance features includes a housing, upon which an activation mechanism, an insertion mechanism, a fluid pathway connection as described above, a power and control system, and a drive mechanism connected to a drug container are mounted. Methods of assembly and operation are also provided.

A resin hollow needle includes a distal end section including a puncture end portion, a large-diameter section having a diameter greater than that of the distal end section, a tapered section that is located between the large-diameter section and the distal end section, and a hub section. The distal end section includes a hole that is provided on a proximal end side in comparison to a distal end and on a distal end side of the tapered section, and communicates with the inside and the outside of a hollow needle, and a tapered puncture end portion. The distal end section has a total length of 7 to 14 mm and a maximum outer diameter of 1.5 to 3.0 mm. The tapered section has a length of 0.3 to 4.7 mm and a taper angle of 10° to 50°. The large-diameter section has a length of 4 mm or greater, and a distal end outer diameter that is greater than the maximum outer diameter of the distal end section by 0.6 to 3.0 mm.

A system for refilling a multi-chamber implantable infusion device is presented. The infusion device has a refill chamber which is accessible through an external septum of a refill port. The refill chamber is divided by an inner septum into an upper reservoir and a lower reservoir. The lower refill chamber is refilled with lower reservoir needles having a needle opening axially placed to align with the lower reservoir. The upper reservoir is refilled with an upper reservoir needle having an opening aligned with the upper reservoir. Magnetic portions are provided in the needles to localize and identify the needle. A processor within the infusion device is connected to magnetic field sensors which sense magnetic portions of the needle and recognize information encoded magnetically within the needle.

A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.

An infusion pump for delivery of a fluid is disclosed. The infusion pump allows a user to selectively control a flow rate of a fluid and includes a spike member that is connectable to an injection port of an intravenous fluid container.
