Clip (40) is mounted in outer housing (38) of needle shield (20) via spade (66) having outer wall (70) exposed to outside of needle shield (20), in order to reduce overall width of needle shield (20).

Abstract: A catheter assembly comprises a catheter (18), a needle (12) having a sharp distal tip disposed within the catheter (18), a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (38) that selectively permits or blocks a flow of fluid through the catheter (18), a valve actuator (54) that moves between a first position and a second position, and a return member (56) that returns the valve actuator (54) from the second position to the first position, and a needle protection member (176) that encloses the sharp distal tip of the needle (12).

Abstract: A catheter assembly includes a flexible catheter (22), a needle (12) having a sharp distal tip, the needle (12) disposed in the flexible catheter (22) and moving from a first position that exposes the needle (12) to a second position, an outer member (26) that is configured to engage and disengage a catheter hub (14), an inner member (28) disposed in the outer member (26), and a needle protection (30) member disposed in the inner member (28), the needle protection member (30) enclosing at least a portion of the needle (12) when the needle (12) is in the second position.

Abstract: A catheter insertion device (10) is provided for positioning and inserting a catheter (14), particularly a midline catheter into a patient. The insertion device (10) includes an introducer needle (18) that extends from the distal end of the catheter during insertion. A manually operated actuator assembly (20) is movable with respect to a housing for deploying the catheter (14) over the distal end of the introducer needle (18). A step-wise movement of the actuator (20) advances the catheter (14) in stages over the introducer needle (18). A shuttling or indexing mechanism (60, 76) advances the catheter and prevents retraction of the catheter once deployed.

Abstract: A system and method for a patch-like, self-contained substance infusion device which can be attached to a skin surface via an adhesive contact surface. A push button activation assembly can then be used to remove an interlock, allowing a disk or Belleville spring assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly. This allows the release of one or more spring-loaded patient needles into the skin surface, and establishes a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button activation assembly further allows the release of one or more improved safety mechanisms after use.

Abstract: A catheter adapter may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A central axis of a fluid path extending through the side port may be disposed at an angle with respect to a longitudinal axis of the catheter adapter. The angle may be less than 45°. Additionally or alternatively to the angle being less than 45°, the catheter adapter may include a wedge and/or an insert configured to facilitate instrument delivery to the catheter assembly via the side port.

Abstract: A catheter assembly (10) comprises a catheter (20), a needle (22) having a sharp distal tip and disposed within the catheter (20), a catheter hub (30) connected to the catheter (20) having the needle (22) passing therethrough, and a housing (70) that encloses the sharp distal tip of the needle (22). An external surface of the catheter hub (30) and an internal surface of the housing (70) each include at least one of a channel member (34) and a raised portion (72) that interfit to restrict motion between the catheter hub (30) and the housing (70).

Abstract: A catheter assembly may include an over-the-needle catheter and introducer needle. The catheter may include a distal tip and an elongate tubular portion proximate the distal tip of the catheter. The distal tip may be constructed of a first material and may include at least a portion of a stepped surface. The tubular portion may be constructed of a second material having a harder durometer than the first material. The introducer needle may include a needle feature having another stepped surface configured to abut the stepped surface of the catheter when the introducer needle is in an insertion position such that proximal movement of the distal tip of the catheter relative to the introducer needle is inhibited.

Abstract: A one-piece catheter (30) and manufacturing method therefor are disclosed. The catheter (30) includes a catheter tube (33) and an adapter (31). The catheter catheter tube (33) includes a tip (331) at one end and an end portion (332) at another other end. The adapter (31) can be configured for receiving a septum (402). The adapter (31) includes a narrow opening. The end portion (332) of the catheter tube (33) is connected to the adapter (31) at the narrow opening for fluid communication between the catheter tube (33) and the adapter (31). The catheter tube (33) and adapter (31) are formed as a one-piece element that is preferably injection molded in a single-shot process. Additional elements, such as one or more retention tabs (313) for attaching to a base can be formed on the catheter (30). The one-piece catheter (30) can be made by a single-shot injection molding process. Additional structures, such as a base can be attached to the catheter (30) by a second-shot injection molding process.

Abstract: A cover for magnetizing a shaft of a tissue-penetrating medical device is disclosed including a sleeve member having a hollow body to form a protective closure over the shaft of the tissue-penetrating medical device. The proximal end of the hollow body provides a receiving space for receiving the shaft of the tissue-penetrating medical device. One or more magnet is disposed on the sleeve member. A magnetic shield composed of one or more shielding materials associated with the cover that minimizes any effects to the clinical environment from magnetic fields generated within the cover. Medical devices and methods of magnetizing the shaft of a tissue-penetrating medical device using the cover are also disclosed.
