Abstract:
A self-sealing catheter valve (1,19) includes a flexible tubular part (2) having a distal opening (6) and an opposite proximal opening (12), and a proximal valve part (5). The proximal valve part (5) has a curved self-sealing flexible diaphragm (7) disposed inside the flexible tubular part (2) and has a base perimeter (8) united with a circumferential wall (9) of the flexible tubular part (2). The curved self-sealing flexible diaphragm (7) has a concave surface (11) facing towards the proximal opening (12), and a convex surface (10) facing towards the distal opening (6), and a flexible diaphragm wall (14) of the curved self-sealing flexible diaphragm (7) has a traverse slit (15). 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.
Abstract:
A port closure system (20) including a retention structure (22), and a valve (24). The retention structure (22) includes a port (28) for establishing communication between an exterior environment (30) and interior volume (32) that can receive a fluent substance. The valve (24) includes a flexible, resilient, self-closing, slit-type valve head (36) with an orifice that is normally closed in an unconstrained condition. The port (28) has a laterally inwardly facing engaging surface (34) and the valve has a laterally outwardly facing peripheral surface (54) that is compressed laterally inwardly by engagement with the surface (34) to increase the resistance of the normally closed orifice to opening when the head (36) is subjected to a pressure differential. The system (20) further includes an annular flange (62) located to extend over at least a portion of an exterior side (38) of the valve head (36) to limit movement of the valve head (36) towards the exterior environment (30).
Abstract:
A surgical tool (1) that is self sealing. The surgical tool includes a body (10) having a tube (12) at a distal end a hub (14) at a proximal end characterized in that a sealing disc (50) is provided that is securable within a sealing disc receiving space (30) positioned through a sidewall of the hub.
Abstract:
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.
Abstract:
A septum for use in sealably covering a fluid cavity of an implantable medical device, such as an access port, is disclosed. The septum is resilient and includes a reinforcement structure that bolsters septum placement over the fluid cavity so as to inhibit unintended separation of the septum from the medical device when the fluid cavity is under pressure, such as during power injection of fluid into the fluid cavity. In one embodiment the septum comprises a resilient septum body that includes a flange disposed about a perimeter thereof. A reinforcement component is disposed in the flange for reinforcing engagement of the flange with a corresponding groove defined about an opening to the fluid cavity of the medical device so as to inhibit unintended detachment of the septum from the medical device. The reinforcement component in one embodiment includes an annular cord disposed in the flange.
Abstract:
An implantable port assembly (10) having a lower housing (12) and an upper housing (14) and at least one chamber (20, 22) and a corresponding septum (16,18) associated therewith. The upper housing (14) includes a plurality of latch arms (30) depending therefrom that latch with corresponding catches (34) of the lower housing for mechanically securing the assembly together during bonding or welding. Each septum (16, 18) includes a peripheral flange (40) held in compression by and between the upper and lower housings (14,12) upon and after assembly. In a dual port assembly (10), a pair of septa (16, 18) are disposed side -by-side with overlapping flanges (54), and the upper housing (14) includes posts (52) extending through apertures (54) through the overlapping flanges (56) that extend into holes (58) in the lower housing (12).
Abstract:
L'invention concerne un dispositif médical implantable (1) destiné à l'injection et/ou au prélèvement de substance fluide dans un organisme et comprenant une chambre (2) délimitée par une paroi (3) qui présente au moins une portion pénétrable (4) au niveau de laquelle ladite paroi (3) peut être transpercée dans le sens de son épaisseur (e) par une aiguille (5), ledit dispositif comportant des moyens de mise en compression transverse (10) de Ia portion pénétrable (4) ainsi que des moyens de retenue (20) conçus pour s'opposer au flambage, vers l'extérieur du dispositif, de la portion pénétrable (4) sous l'effet de la compression (F1).
Abstract:
A vascular access device may include a body, housing, neck, and a septum with a substantially non-gaseous cross section. A method of operating a septum of a vascular access device may include providing a vascular access device in an external environment and actuating the septum without transferring a substantial amount of gas from within the device to the external environment of the device.
