A valve for sealing the hub of a sheath assembly is provided. The valve includes a valve body having a solid thickness extending between a proximal surface and a distal surface. A bisecting slot extends across the proximal surface of the valve body and terminates at a depth less than the thickness of the valve body such that a portion of the valve body distally of the slot defines a bridge extending between opposed halves of the valve body such that the distal surface of the valve body is substantially continuous and a central portion of the proximal surface of the valve body is concave and defines a concave proximal portion.

A hemostasis valve for use in a medical device. The hemostasis valve may include a generally cylindrical body having a proximal side, a distal side, and a thickness extending therebetween. The proximal side may include a tapered central region having a surface sloped towards a center of the body and the distal side may include a distally extending curved central region.

A catheter assembly may include a catheter adapter. A body of the catheter adapter may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. A catheter may extend distally from the distal end of the body. The catheter adapter may include a side port, which may extend outwardly from the body. The catheter assembly may include a valve disposed within the lumen. The valve may include a channel extending through the valve. The catheter assembly may include a cannula fixed within the side port and disposed within the channel. The cannula may include an opening, and the valve may be configured to compress to expose the opening from within the valve.

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 catheter assembly may include a catheter adapter. A body of the catheter adapter may include a distal end, a proximal end, and a first lumen extending through the distal end and the proximal end. The catheter adapter may include a side port, which may extend outwardly from the body. The side port may include a second lumen, which may be perpendicular to the first lumen. The catheter assembly may include a catheter extending distally from the distal end of the body. The catheter assembly may include a valve disposed within the first lumen. The valve may include an outer surface that is cylindrical and may seal the first lumen from the second lumen. The catheter assembly may include a divider disposed with the second lumen. The divider may divide the second lumen into a plurality of openings and may increase a burst value of the valve.

A catheter assembly may include a catheter adapter that includes a distal end, a proximal end, and an inner surface forming a lumen. The lumen may extend between the proximal end and the distal end. The catheter assembly may also include a cannula and a cannula hub. The cannula hub may include an outer portion disposed outside of the catheter adapter and an inner portion disposed within the catheter adapter. The cannula may extend distally from the inner portion. In response to the outer portion sliding proximally along an outer surface of the catheter adapter, the cannula may be withdrawn proximally into the catheter adapter. The outer portion may be configured to slide proximally to a locked position in which the cannula hub is locked with respect to the catheter adapter, and a distal tip of the cannula is disposed within the catheter adapter.

A hemostasis valve for use in a medical device. The hemostasis valve may include a generally cylindrical body having a proximal side, a distal side, and a thickness extending therebetween. The proximal side may include a tapered central region having a surface sloped towards a center of the body and the distal side may include a distally extending curved central region.

A cannula for use in an access assembly includes an instrument valve housing including first and second housing sections and defining a cavity and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism. The guard assembly includes a plurality of guard members. Each guard member of the plurality of guard members includes a ring portion and a flap portion. The flap portions of the guard members of the guard assembly are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.

A catheter assembly comprises a catheter (18), a needle (12) having a sharp distal tip disposed within the catheter (18), a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (38) that selectively permits or blocks a flow of fluid through the catheter (18), a valve actuator (54) that moves between a first position and a second position, and a return member (56) that returns the valve actuator (54) from the second position to the first position, and a needle protection member (176) that encloses the sharp distal tip of the needle (12).

A catheter assembly including a flexible catheter, a needle having a sharp distal tip, the needle disposed in the flexible catheter and moving from a first position that exposes the needle to a second position, an outer member that is configured to engage and disengage a catheter hub, an inner member disposed in the outer member, and a needle shield for shielding at least a distal end of the needle when the needle is in the second position and the needle being disposed through the needle shield in the first position.
