Direct Fluid Path for Inline Dual Lumen Port

Embodiments disclosed herein are directed to a dual, in-line port having a direct fluid path between the proximal reservoir and the stem. The port includes a conduit extending through the distal reservoir and defining a lumen in fluid communication with the proximal reservoir and the stem. The axis of the conduit lumen is aligned with stem lumen to minimize any tortuous fluid pathway and reduce fluid flow resistance. The port can further include a needle guard extending over the distal reservoir and configured to prevent an access needle from impinging on the conduit when accessing the distal reservoir. Embodiments can further include a removable reservoir insert that defines the distal reservoir.

A port (1) for a catheter comprises: a housing (10) having at least two fixing holes (120, 20A, 120B); a cavity (140) arranged in the housing (10) for receiving a fluid; a membrane (13) attached to the housing (10) and arranged on an opening (102) of the housing (10) for sealing the opening (102) such that the cavity (140) is enclosed in the housing (10) in a fluid-tight manner; and a catheter (2) connected to the housing (10), the catheter (2) being in fluid connection with the cavity (140). In addition a yarn guide device (16) is arranged on the housing (10) in between the membrane (13) and the catheter (2), the yarn guide device (16) comprising a guide channel (161) formed in the housing (10) for receiving a yarn (3) for fixing the port (1) to an object and for guiding the yarn (3) in between the membrane (13) and the catheter (2). In this way a port is provided which allows for an easy fixing of the port by means of a yarn and reduces the risk of the yarn interfering with the catheter attached to the port.

IMPLANTABLE VASCULAR ACCESS PORT WITH DUAL, HIGH-FLOW TRANS-CHAMBER AND LOW-FLOW, ACCESS, AND NEEDLE LOCK FOR HIGH-FLOW
20240382735 · 2024-11-21 ·

A vascular access port has a single unitary septum, included in an upper wall of the port body. The septum has an arched or curved portion extending at least partially down a side of the port body opposite the outlet port and covering the lateral access zone or straight-line-access aperture to the outlet port/aperture.

Low-Profile Single And Dual Vascular Access Device

A low-profile access port for subcutaneous implantation within a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable catheter-bearing needle access to the port without difficulty. In one embodiment, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end, and a receiving cup. The receiving cup is funnel shaped to direct a catheter-bearing needle into the conduit via the inlet port. The conduit is defined by the body and extends from the inlet port to an outlet defined by a stem. A bend in the conduit enables catheter advancement past the bend while preventing needle advancement. A valve/seal assembly is also disposed in the conduit and enables passage of the catheter therethrough while preventing fluid backflow. The body includes radiopaque indicia configured to enable identification of the access port via x-ray imaging.

MEDICAL ACCESS PORT, SYSTEMS AND METHODS OF USE THEREOF

A medical device comprising a subcutaneous access port having an access port body and at least one needle having a removable needle tip and a needle shaft defining a needle lumen; the at least one needle housed within the access port body, the at least one needle extendable and retractable relative to the access port body; and a needle shift mechanism operable such that the at least one needle is extendable from and retractable into the access port body at a plurality of positions of the access port body.

A port (1) for a catheter comprises: a housing (10) having at least two fixing holes (120, 20A, 120B); a cavity (140) arranged in the housing (10) for receiving a fluid; a membrane (13) attached to the housing (10) and arranged on an opening (102) of the housing (10) for sealing the opening (102) such that the cavity (140) is enclosed in the housing (10) in a fluid-tight manner; and a catheter (2) connected to the housing (10), the catheter (2) being in fluid connection with the cavity (140). In addition a yarn guide device (16) is arranged on the housing (10) in between the membrane (13) and the catheter (2), the yarn guide device (16) comprising a guide channel (161) formed in the housing (10) for receiving a yarn (3) for fixing the port (1) to an object and for guiding the yarn (3) in between the membrane (13) and the catheter (2). In this way a port is provided which allows for an easy fixing of the port by means of a yarn and reduces the risk of the yarn interfering with the catheter attached to the port.

GENERATING MICROBUBBLES FOR BUBBLE STUDIES

A method for generating microbubbles may include providing a syringe having a barrel defining an interior volume, a plunger, a tip and a check valve assembly. The check valve assembly may have an inlet port; a check valve that is configured to open when the plunger is drawn back by a user; and a nozzle in fluid communication with the interior volume and, when the check valve is open, in fluid communication with the inlet port. The method may include drawing liquid into the interior volume; removing a seal from the inlet port and drawing gas adjacent the inlet ports into the interior volume to form microbubbles in the liquid already drawn in; coupling the tip to an intravenous line associated with a patient undergoing a bubble study; and depressing the plunger to force the liquid and the formed microbubbles into the intravenous line.

Catheter insertion apparatus with continuous visible flashback

The present disclosure relates to a catheter insertion apparatus including a hollow needle body connected to a needle hub, and a catheter that removably fits over the needle body. The needle body has a sharp distal needle tip for piercing a blood vessel wall. An internal flow passage of the needle hub is in fluid communication with the hollow needle body. An elongated housing is connected to the needle hub and includes a lumen in fluid communication with the internal flow passage of the needle hub. An integrated guide assembly is slidably mounted to the housing and is operable to move between a retracted position and an extended position. A flashback chamber is operable to receive a continuous flow of blood before, during, and after movement of the guide assembly between its retracted and extended positions. A safety guard may provide protection from the sharp needle tip.
