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.

The present disclosure relates to a hemostasis valve with a selectively coupled torque device. The hemostasis valve may include a first mating interface, and the torque device may comprise a second mating interface. The first interface may comprise a groove that retains the second interface, which may comprise a ridge. An axial force may couple and decouple the interfaces. The interfaces may be configured to allow the torque device to rotate relative to the hemostasis valve when in a coupled position.

The fluid delivery devices, systems and methods described herein include a subcutaneous port, a catheter, and a connection assembly configured to fluidly couple the port and catheter.

Sheath assembly for the insertion of a cord-shaped element, comprising an introducer sheath, and an auxiliary sheath for insertion into the introducer sheath together with the cord-shaped element. In some examples, the auxiliary sheath has a housing configured to detachably couple to the introducer sheath housing, and to detachably fasten the cord-shaped element with respect to the auxiliary sheath housing.

A medical device may include a septum seal including a septum wall having portions defining a septum opening, and a plurality of flaps extending over the septum seal toward the septum opening, wherein the flaps define a flap opening that overlaps with the septum opening.

Sheath assembly for the insertion of a cord-shaped element (32, 105), comprising an introducer sheath (101) and an auxiliary sheath (104) for insertion into the introducer sheath (101) together with the cord-shaped element (32, 105), with first fastening means (106) for detachably fastening the auxiliary sheath to the introducer sheath, and with second fastening means (107) for detachably fastening the cord-shaped element to the auxiliary sheath, wherein the introducer sheath (101) has a first sheath housing (13, 114) and a distal tubular section (11, 41 a) that terminates in the first sheath housing, and a first flushing device (108), wherein the auxiliary sheath (104) has a second sheath inner chamber (111), a distal, tubular part (112) and a second flushing device (109).

A medical valve assembly includes a tube extending between a first and second tube end along an axis, and a plunger plate extends radially from the second tube end. A valve housing surrounds the tube and includes a radially inwardly extending flange. A compression member is biased against the plunger plate and compresses an elastomeric seal from a non-compressed condition to a compressed condition to establish a sealed condition of the medical valve assembly. An inner surface of the elastomeric seal in the non-compressed condition has a plurality of planar portions and a plurality of radiused portions, with adjacent planar portions interconnected with one of the radiused portions to improve a closure of the elastomeric seal during compression. The inner surface preferably includes three planar portions and three radiused portions to define a generally triangular-shaped inner surface as viewed in cross section in the non-compressed condition.

Access assemblies includes an instrument valve housing and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a guard assembly, and a seal assembly disposed distal of the guard assembly. In embodiments, the seal assembly includes a plurality of seal segments in an overlapping configuration. Each seal segment of the plurality of seal segments includes a seal portion having a smooth surface and a ribbed surface. The ribbed surfaces include a plurality of ribs extending in a radial direction.

A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip disposed in the catheter (22), a catheter hub (14) housing the catheter (22) and the needle (12), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to enclose at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).

A medical valve has a housing with an inlet housing and an outlet housing. The interior of the inlet housing and/or the outlet housing has a contact surface. A resilient element sits within the housing and controls fluid flow through the inlet. The resilient element has a proximal portion with a normally closed aperture configured to open when actuated by a medical device. The resilient element also has a distal portion adjacent to the outlet, and a central portion between the proximal portion and the distal portion. The central portion has a wall that defines a fluid chamber in the open mode and in the closed mode. The wall has at least one projection extending radially outward. The projection maintains compressive contact with the contact surface of the housing and applies an inwardly compressive force on the resilient element, increasing the wall stiffness.
