A peripheral intravenous catheter assembly may include a low-drag septum. The septum may include a body having a distal end and a proximal end, which may be sealed. The septum may include a slot disposed within an outer surface of the body and oriented along a longitudinal axis of the body. The slot may include a distal end spaced apart from the distal end of the body, and a proximal end spaced apart from the proximal end of the body. An introducer needle may extend through the slot.

A medical device includes: a first member including: a body portion, and an anchor, wherein a resin material of the anchor is different from a resin material of the body portion, and wherein the anchor is interlinked to the body portion; and a second member including a connecting portion that is connected to the anchor, wherein a resin material of the second member is the same as the resin material of the anchor.

A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.

An infusion set system includes a base and a fluid connector removably coupleable thereto. The fluid connector includes a fluid path portion and at least one connector latch displaceably connected to the fluid path portion and displaceable to a latching position in which at least a portion of the connector latch extends into the fluid path portion, which includes a cannula extending from a top interior surface thereof, and a plurality of internal sidewalls corresponding to at least two of a plurality of flat side surfaces of at least one of a base section and a base latch, thereby facilitating connection between the base and the fluid connector in a plurality of discrete rotational connecting positions. When the fluid connector is locked to the base, the at least one connector latch engages a base latching portion of the base and restricts proximal displacement of the fluid connector.

A device (1) for dispensing a fluid, in particular under aseptic conditions, preferably to a patient. The device comprises a conveying device (2) for conveying the fluid to a dispensing opening (3). The device (1) also comprises a coupling element (4) for coupling a syringe (5). The fluid can be conveyed from the syringe (5) to the dispensing opening (3) via the coupling element (4) and the conveying device (2) exclusively by the effect of the conveying device (2). The invention further relates to a system for dispensing a fluid under aseptic conditions, comprising such a device (1) and to a syringe (5) that can be coupled to the coupling element (4).

Disclosed is septum arrangement having a pierceable septum. The pierceable septum has first and second surfaces positioned opposite to one another and a peripheral surface. A compression element has at least two compression members that partially or fully surround the peripheral surface and has at least two gripping members. Each compression member is connected to at least one gripping member, and the gripping members extend from the compression members towards a common axis (A) which intersects the first surface. A resilient element exerts a biasing force on the pierceable septum that is directed towards the common axis (A). The gripping members define an aperture between them such that introduction of a needle into the aperture exerts a force on the gripping members that counteracts the biasing force and moves the gripping members apart from each other.

A catheter assembly may include a catheter adapter, a septum housing, and a septum. The catheter adapter may include a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall. The septum housing may include one or more protrusions and may be secured to the inner wall by one or more of the following: an interference fit between the one or more protrusions and the inner wall, a snap fit between the one or more protrusions and the inner wall, and bonding between the one or more protrusions and the inner wall. The septum may be at least partially disposed within the septum housing and configured to at least substantially seal the lumen.

Provided herein is a fluid pathway connection assembly, e.g., for connecting a fluid flowpath within a drug delivery device for delivery of a medicament to a target site. The fluid pathway connection assembly comprises a hollow needle piercing member, a sleeve fixedly engaged with the piercing member and a pierceable seal configured to sealingly engage the piercing member or the sleeve. Upon, sealing engagement, the piercing member or the sleeve and the pierceable seal form a volume within which a portion of the piercing member is disposed. The fluid pathway connection assembly is activated by relative movement between the piercing member and the pierceable seal and activation causes the piercing member to pierce the pierceable seal, thereby establishing a fluid flowpath through the pierceable seal. Upon incorporation of the assembly into a sealed fluid flowpath, the volume is isolated from the environment and maintains the sterile condition of the portion of the piercing member disposed therein. Also provided herein are drug delivery pumps and methods of operating and assembling the assemblies and pumps described herein.

PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.

A catheter assembly may include a catheter adapter, a septum housing, and a septum. The catheter adapter may include a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall. The septum housing may include one or more protrusions and may be secured to the inner wall by one or more of the following: an interference fit between the one or more protrusions and the inner wall, a snap fit between the one or more protrusions and the inner wall, and bonding between the one or more protrusions and the inner wall. The septum may be at least partially disposed within the septum housing and configured to at least substantially seal the lumen.
