  • Hemostasis valves and methods for making and using hemostasis valves
    Patent number: 10953214
    Abstract: Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a distal end region and a proximal end region. A first seal member may be disposed within the proximal end region of the main body. A plunger may be coupled to the proximal end region of the main body. The plunger may be designed to shift between a first position and a second position. A first locking member may be disposed along the proximal end region of the main body. A second locking member may be disposed along the plunger. The second locking member may be designed to engage the first locking member.
    Type: Grant

  • Hemostasis valves and methods for making and using hemostasis valves
    Patent number: 10737086
    Abstract: Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a distal end region and a proximal end region. A first seal member may be disposed within the proximal end region of the main body. A cartridge may be at least partially disposed within the proximal end region of the main body. The cartridge may include a second seal member. A plunger may be coupled to the proximal end region of the main body. A rotation limiting member may be positioned adjacent to the proximal end region of the main body. A tab member may be positioned adjacent to the proximal end region of the main body. The tab member may be designed to rotate relative to the proximal end region of the main body until the tab member engages the rotation limiting member.
