Deployment handle for delivery of implants

A delivery device for controllably delivering multiple implants (e.g., intravascular implants) is described herein. The delivery device may include a lockout mechanism to prevent against inadvertent implant deployment prior to initial use. The delivery device may also include a re-sheath mechanism to allow for re-sheathing of an inner core assembly prior to removal of the delivery device from an initial deployment site. The delivery device may also further include a mechanism configured to prevent against re-sheathing of a partially-deployed implant.

Graft-port hemodialysis systems, devices, and methods
10456570 · 2019-10-29 · ·

The present invention relates to subcutaneously implanted graft-port systems, devices and methods for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a flattened plateau-like surface for receiving an access tube. The flat surface may include a tactile or visual guide to assist with placement of the access tube into the tapered seat. Optional valve mechanisms reduce the size and form factor of the implantable graft-port device and seals the conduit of the port closed to physiologic pressures until the valve is opened upon percutaneous insertion of the access tube. The access tube does not pass into the conduit. A mismatch fit between the access tube and tapered seat causes a decrease in the cross-sectional sealing area, a reduction in the overall device size, and an increase in blood flow during treatment. Lock solutions to prevent fowling and infection are also disclosed.

SELF-FLUSHING CONNECTOR
20190321618 · 2019-10-24 ·

A self-flushing connector includes a housing having a cavity, a first inlet port, a second inlet port, and an outlet port. A collapsible valve is disposed within the cavity. A first flow path extends from the first inlet port to the outlet port. The first inlet port and the second inlet port are fluidly connected through a gap defined between the body of the collapsible valve and an inner wall of the housing defining the cavity. A second flow path extends from the second inlet port to the first flow path. When the collapsible valve is in a closed state, the collapsible valve fluidly disconnects the second flow path from the first flow path while allowing fluid to flow through the first flow path. When the collapsible valve is in an open state, the second flow path is fluidly connected to the first flow path.

Intravascular Catheter Care Pre- and Post-Flushing
20240165320 · 2024-05-23 ·

An intravascular catheter care device comprising a flush syringe having an integrated disinfecting unit associated therewith and a method for disinfecting an intravascular catheter, wherein the disinfecting unit includes a first disinfecting pad enclosed between a first and second layer of a flexible peel film. The first layer can be removed from the second layer to expose the first disinfecting pad. A second disinfecting pad can be enclosed between either the second layer of the peel film and a third layer of the peel film or between a second layer of the peel film and a cap that can be secured to the connector. The second layer can be removed from the third layer or the cap to expose the second disinfecting pad. The first pad can be used to disinfect the connector of the intravascular catheter prior to flushing and the second pad can be used after flushing.

MICRO-INFUSION DEVICE AND INFUSION SET

Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.

CONNECTOR

A connector, comprising: a housing which has a first port, a second port, and a first chamber in communication with the first port and the second port; a cover, which is connected to the housing and which has a second chamber in communication with the first chamber; and a bulging portion, which is disposed in the first chamber and protrudingly extends toward the second chamber. A side groove which obliquely curves and extends towards the second chamber is provided in the first chamber. The groove structure of the connector can guide a portion of fluid which is flowing into the first chamber from the first port towards the second chamber, so as to form a spiral upward vortex, thereby enlarging a flushing region, increasing the flushing efficiency, and reducing the risk of pollution.
