HANDHELD MULTI-NEEDLE VASCULAR ACCESS DEVICE

A handheld vascular access device for gaining access to a patient's vessel includes a hub, a plurality of access needles and a manifold. The hub has an inner wall and side walls that define a plurality of ports. Each of the plurality of ports has a proximal port end and a distal port end. The proximal port ends define a proximal cross-sectional area and the distal port ends define a distal cross-sectional area. The proximal cross-sectional areas are greater than the distal cross-sectional areas. Each of the plurality of ports taper from the proximal port end to the distal port end. The plurality of hollow access needles is arranged along a plane and fixedly coupled to the distal end of the hub. Each of the plurality of needles has a tip. The manifold removably engages the hub at the proximal end of the hub.

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.

Valved catheter assemblies and related methods

Valves are described for intravenous (IV) catheter assemblies for controlling fluidic flow. The valve can prevent blood leakage in multiple access use situations. A thinner area of the valve around a slit is provided. The thicker area of the valve is to provide rigidity to the valve so that it is able to return to a closed configuration when a Luer connector is removed.

Lockable Exchangeable Fluid Connector and Method
20230184362 · 2023-06-15 ·

Disclosed herein is a fluid connector system configured to couple a first fluid line structure, e.g. port, with a second fluid line structure, e.g. catheter. The connector system can include a connector body and one or more locking mechanisms designed to transition between an unlocked position and a locked position. The locking mechanism includes a first lever arm rotatably coupled to the connector body, and a second lever arm rotatably coupled to the first lever arm. The second lever arm can further be rotatably and releasably coupled to the port. Rotating the first lever arm uses mechanical advantage to urge the port to engage a catheter ensuring a tight seal therebetween even under high fluid pressures.

SINGLE USE CAPS AND COVERS FOR VASCULAR ACCESS DEVICES, AND KITS AND METHODS FOR USING THE SAME
20220370782 · 2022-11-24 · ·

This invention concerns improved single use caps or covers for vascular access devices such as needlefree connectors that are used, for example, in intravenous administration sets and extension sets. Removal of a single use cap or cover according to the invention from a vascular access device destroys the cap such that it cannot be reused. Such single use caps and covers will help ensure compliance with infection prevention protocols in healthcare settings, which will assist in reducing the incidence of healthcare-associated infections (HAIs), particularly catheter-related blood stream infections. Assemblies and kits its including such caps and covers, for example, IV administration and extension sets that include one or more needlefree connectors, as well as methods for using such caps and covers, are also described.

Dual Reservoir Implantable Access Port

An implantable access port for use in transferring fluid transdermally between an external fluid storage or dispensing device and a site within a patient is disclosed. The access port includes a body, at least two reservoirs defined within the access port body, and at least one septum secured to the body and enclosing the reservoirs within the body. The access port also includes reservoir outlets defined within the reservoirs. The access port also has body conduits defined within the body and in fluid communication with the reservoir outlets and external openings defined in the exterior of the body. An implantable access port and system for use in apheresis is also provided that includes an implantable access port, at least one needle, and a catheter that is fluidly connected to the access port.

Drug Delivery Systems and Methods

Drug delivery systems and methods are disclosed herein. In some embodiments, a drug delivery system can be configured to deliver a drug to a patient in coordination with a physiological parameter of the patient (e.g., the patient’s natural cerebrospinal fluid (CSF) pulsation or the patient’s heart or respiration rate). In some embodiments, a drug delivery system can be configured to use a combination of infusion and aspiration to control delivery of a drug to a patient. Catheters, controllers, and other components for use in the above systems are also disclosed, as are various methods of using such systems.

RETRIEVABLE ACCESS VALVE

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.

Medical device
09821150 · 2017-11-21 · ·

A device for positioning a subcutaneous port during an access procedure, said device comprising a dome (1) of plastic material, said dome being shaped to fit directly over the subcutaneous port, and a flange (3) extending laterally from the dome which is able to contact a surrounding skin area, wherein the device is a unitary device which is configured to be deformable or fracturable so as to facilitate removal of the device from the surrounding skin area.

ULTRASOUND-PLACED PAIN MANAGEMENT SYSTEM AND METHOD WITH SUBCUTANEOUS CATHETER
20230166030 · 2023-06-01 ·

A catheter system includes a medication dispenser located external to a patient. A subcutaneous port is placed internally to the patient and receives a quantity of medication. The port can be filled from a syringe or medication dispensing system. An echogenic catheter can be placed in proximity to a patient's nerve or nerve center using a point-of-care ultrasound imaging system. A method of administering a nerve block or other medication subcutaneously to a patient includes the steps of placing a subcutaneous port using ultrasound imaging for guidance and administering pharmacologic agents via a catheter connected to the port. Alternative embodiment catheter systems include echogenic tips and a stylet to facilitate accurate placement.
