Embodiment Construction

[0152]In some embodiments thereof, the present disclosure relates to methods for facilitating and / or improving the repeated delivery of fluids (eg, fluids carrying nutrients, drugs, and / or agents such as chemotherapeutic agents) into the vasculature of a subject and more particularly but not exclusively relate to vascular access ports and methods of delivery and deployment thereof within the body of a subject. In some embodiments, the vascular access ports of the present disclosure can improve surgical implantation of access ports and catheters by reducing the size or number, duration, and / or complexity of surgical procedures, such as incisions, incisions, and tunnels. safety and / or effectiveness of the procedure, thereby also providing the patient with a less traumatic experience and easier recovery.

[0153] Figure 1A to Figure 1B A side cross-sectional view and a top cross-sectional view, respectively, are schematically illustrated of an exemplary vascular access port 10, ...

Abstract

Toggle vessel access ports and methods of deploying the same are disclosed. The port includes: a port body coupled with a diaphragm member covering a cavity defined by the port body; and at least one port body extension that is restrictively movable along at least one defined route on the port body. The port is selectively changeable from a delivery configuration to a deployed configuration by moving the at least one port body extension along at least one defined route, with the at least one port body extension and the port body approaching along a median plane of the port body, and at least one of the port body extensions is spaced apart transversely to the median plane, thereby reducing the aspect ratio of the toggle vessel access port.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 62 / 872,022, filed July 9, 2019, U.S. Provisional Patent Application No. 62 / 961,374, filed January 15, 2020, and PCT Application No. . Priority to PCT / US20 / 20759; the entire contents of all related applications set forth in this paragraph are hereby incorporated by reference in their entirety. Background technique [0003] Repeated needle punctures used to facilitate delivery or withdrawal of fluids (eg, drugs or agents) into the patient's vasculature cause damage to local tissue and reduce target vascular function and needle placement accuracy. This phenomenon is often evident, for example, in chronic diabetic, dialysis or chemotherapy patients requiring continuous and repeated administration of intravenous fluids over prolonged periods of time. [0004] A vascular access port is a device that enables such repeated punctures and fluid administrations while ...
