    Abstract: A guidewire stabilization mechanism (100) for a catheter placement system (10) can include an actuator button (132) that can be actuated by the user to grip the guidewire (30) in a locked position. With the guidewire (30) locked relative to a housing of the stabilization mechanism (100) a user can detach a needle hub (28) from the housing (110) and withdraw the needle (20) proximally. A portion of the guidewire (30) can pass through a needle slot (26) to disengage the needle (20) from the guidewire (30). The stabilization mechanism (100) can prevent the guidewire (30) from being dislodged from the vasculature as the needle (20) is withdrawn. The stabilization mechanism (100) can be biased towards the unlocked position, towards the locked position, can be bistable in both the locked and unlocked positions, or can be activated by the removal of the needle (20).

    Abstract: Disclosed are splittable sealing modules for insertion assemblies of rapidly insertable central catheters ("RICCs") and methods thereof. A RICC insertion assembly can include a RICC, an introducer needle, an access guidewire, and a coupler coupling the RICC and the introducer needle together. The introducer needle can include a proximal portion of a sealing-module insert coupled to a distal portion of a needle hub. The coupler can include a coupler housing including a sealing-module cavity and a distal portion of the sealing-module insert disposed in the sealing-module cavity. The sealing-module cavity and the proximal and distal portions of the sealing-module insert form a splittable sealing module of the RICC insertion assembly. The splittable sealing module can be configured to separately seal around the introducer needle and the access guidewire disposed therein when the proximal and distal portions of the sealing-module insert are compressed in the sealing-module cavity.

    Abstract: A mechanical dilator 100 is disclosed, which can include a first arm 104A coupled to a second arm 104B by a fulcrum 116, the first arm and the second arm cooperatively defining a lock and stop mechanism configured to limit lateral movement of the first arm with respect to the second arm. The mechanical dilator can further include a dilator body 110 having a first side extending from the first arm and a second side extending from the second arm, where the fulcrum is configured to translate lateral movement of the first arm relative to the second arm to lateral movement of the first side relative to the second side.

    Abstract: A valve connector for a tunable valve is disclosed, with tunable features to allow for optimization. The tunable valve can include slits, which may be preferentially placed, angled and sized to optimize the crack pressure, maintenance pressures, and clearance characteristics of the connector. The tunable valve may also include a recess in the area of an exemplary center slit, which may be sized further modify the characteristics of the connector valve. The valve may be preferentially curved along either a lateral axis or a transverse axis. The tunable valve may be a proximal valve that is capable of being secured between proximal housing and distal housing. The proximal housing opening may be preferentially shaped.

    Abstract: Disclosed are rapidly insertable central catheter ("RICC") insertion assemblies and methods. For example, a RICC insertion assembly (100) can include a RICC (102), an access guidewire (106), an introducer needle (104), and a coupler (108) coupling the foregoing components together. The introducer needle (104) can include a needle shaft (140) and a sheath (142). The needle shaft (140) can include a longitudinal needle slot (148). The sheath (142) can seal the needle slot (148) thereunder except for a sheath opening (162) thereto in a proximal portion of the sheath (142). The coupler (108) can include a coupler housing (178) and a valve module (180) disposed in the coupler housing (178). The valve module (180) can seal the needle shaft (140) and the sheath (142) therein. The access guidewire (106) can include a proximal end coupled to the coupler (108) and a distal end disposed in the introducer needle (104), thereby enforcing a loop in the access guidewire (106). The RICC (102) can be disposed over the loop in a ready-to-deploy state of the RICC insertion assembly (100).

    Abstract: Rapidly insertable central catheters ("RICCs"), introducers, and insertion devices including combinations and methods thereof are disclosed. For example, a RICC system can include an introducer and a RICC insertion assembly including a RICC assembly disposed in a RICC insertion device. The RICC assembly can include a RICC, an access guidewire, and a splittable casing over a catheter tube of the RICC and the access guidewire forming a longitudinal composite. The RICC insertion device can include a frame and a nose cover forming a split channel that splits away from a through channel of a nose of the frame. The RICC insertion device can be configured for advancing the RICC assembly by rolling the longitudinal composite across roller wheels disposed in the frame. The through channel can be configured for advancing the catheter tube therethrough while the split channel can be configured for both splitting and passing the splittable casing therethrough.

    Abstract: Advanced catheter placement systems (100) require disengaging a needle (120) from the guidewire (130) without disturbing a position of the guidewire (130) within the vasculature. Embodiments include withdrawing the needle (120) proximally and drawing the needle (120) over a splitter system (180) that includes a splitter wedge (182). The splitter system (180) separates the needle (120) along a longitudinal axis. A portion of the guidewire (130) can then pass between a first portion (120A) and a second portion (120B) of the needle (120), allowing the needle (120) to disengage the guidewire (130). A catheter (150) disposed on a proximal portion of the guidewire (130) can then be advanced thereover into the vasculature. A needle safety system (190) can adhere a puncture¬ resistant adhesive tape (192) to the split portions (120A, 120B) of the needle (120). The tape (192) can encapsulate the portions (120A, 120B) of the needle (120) mitigating any damage or trauma caused by sharpened edges of the needle portions (120A, 120B).
