Integrated vascular delivery system

An integrated vascular delivery system and method of use, the system including: a frame having a catheter hub that provides a first anchoring point on the patient and receives a catheter insertable in the patient to transfer fluid at an insertion site, a stabilization hub that provides a second anchoring point on the patient, at least one lateral member extending between the catheter and stabilization hubs, and a fluidic channel. The frame operates in a folded configuration in which the hubs are coupleable and an unfolded configuration in which the anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter. In some embodiments, the system further includes a septum that helps prevent fluid leakage from the catheter hub, or a needle shield that covers the distal end of a needle used during catheter insertion.

INFUSION DEVICE WITH RELEASABLE FLUID CONNECTOR

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.

Implantable drug storage devices for drug delivery

In one embodiment, a fluid storage device includes a rigid outer housing that defines a septum cavity, a reservoir cavity, and a channel that extends between the two cavities, the outer housing further defining an outlet in fluid communication with the reservoir cavity, a septum provided within the septum cavity, the septum being made of an elastic polymer and facilitating refilling of the fluid storage device, and a thin, collapsible membrane that does not generate significant restoring forces when it is deformed as fluid is drawn from the reservoir cavity and, therefore, does not completely or partially return to its initial non-deformed shape even if the outlet of the device remains open after doses are administered.

Septum securement

A catheter assembly may include a catheter adapter, which may include a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The distal end may include a catheter configured to be inserted into vasculature of a patient. The catheter assembly may also include a septum, which may be disposed within the lumen of the catheter adapter. The septum may be secured within the lumen in response to increased pressure by one or more of the following: one or more septum stoppers, a retention disc of a needle assembly, a U-shaped washer, and a conical washer.

HEMOSTASIS SEALING DEVICE WITH CONSTRICTION RING
20170361083 · 2017-12-21 ·

Aspects herein relate to a medical device for providing a leak-resistant seal for use in a vascular access device. In various embodiments, a device for vascular access hemostasis is included. The device can include an enclosure configured to at least partially receive a medical device, the enclosure defining a cavity. The enclosure can have a first seal portion and a second seal portion, the cavity disposed between the first seal portion and the second seal portion. The enclosure can include the second seal portion comprising a split, septum seal. The enclosure can include a barrel in structural communication with the second seal portion. The device can include a constriction ring disposed around the barrel, the constriction ring interfacing with the second seal portion to limit movement of the split, septum seal.

Flanged sealing element and needle guide pin assembly for a fluid infusion device having a needled fluid reservoir

A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.

SELF-SEALING CATHETER VALVE
20170326341 · 2017-11-16 ·

A self-sealing catheter valve that includes a flexible tubular part having a distal opening and an opposite proximal opening, and a proximal valve part. The proximal valve part has a curved self-sealing flexible diaphragm disposed inside the flexible tubular part and has a base perimeter united with a circumferential wall of the flexible tubular part. The curved self-sealing flexible diaphragm has a concave surface facing towards the proximal opening, and a convex surface facing towards the distal opening, and a flexible diaphragm wall of the curved self-sealing flexible diaphragm has a traverse slit. The self-sealing catheter valve provides an efficient self-closing mechanism for a peripheral catheter assembly and constitutes an efficient barrier against potential contagious spread from the patient to the surrounding environment by blood born disease e.g. HIV, hepatitis and Ebola viruses.
