A gasket for a hemostasis valve includes an annular wall, a membrane, a central protrusion on the membrane, and a plurality of ligaments attached to the central protrusion extending radially to the annular wall. The membrane, central protrusion, and ligaments are divided by slits into a plurality of flaps, with each flap bounded along an outer circumferential edge by the annular wall, along an inner circumferential edge by the central protrusion, and along its radial edges by segments of the ligaments. Two such gaskets can be arranged, back-toback, in a hemostasis valve. To facilitate such assembly, each gasket can include a plurality of positioning protrusions extending axially and a plurality of positioning recesses set into a circumferential surface, with the protrusions and recesses having complementary shapes for proper interconnection and fit between gaskets.

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.

A medical connector for use in a fluid pathway includes a substantially transparent housing having a proximal end with a proximal opening and a distal end with a distal opening, and a cavity extending therebetween. The connector provides a substantially visible fluid flow path extending through a substantial portion of the connector.

A new process of manufacturing a hybrid cannula may include creating a first part with at least two components, overmolding at least two components of a second part to a channel in each component of the first part, and fixing the components of the first part together. The second part may include various types of features such as thick/thin dams, squirt membranes, and/or duck bill dams inside the hybrid cannula. Each dam may have any number, shape, orientation, and length of slits/openings. The slits/openings may allow passage of an instrument while the dam(s) may prevent fluid from passing through the hybrid cannula. A third part may optionally be overmolded to at least a portion of the first part, at least a portion of the second part, or both. The third part may provide an extension, a flange, or a combination thereof at a distal end of the hybrid cannula.

A seal assembly including a septum seal, a lower seal support, an upper seal support and a return spring is disclosed. The septum seal includes an orifice and a plurality of apertures. The lower seal support includes an engagement surface configured to engage a portion of the septum seal. The upper seal support includes a plurality of fingers, wherein each of the plurality of fingers is configured to extend through a corresponding aperture of the septum seal. The return spring includes a collar portion and a plurality of spokes extending radially outward from the collar portion. At least a portion of the return spring may be sandwiched between the lower seal support and the upper seal support. The plurality of spokes is configured to bias the seal assembly toward a radial center of a housing.

A hub is provided for a sheath, catheter, or other tubular device that includes a tubular body comprising a proximal end, a distal end, and a hub passage extending between the proximal end and the distal end; a valve mounted in the tubular body adjacent the proximal end comprising a proximal surface adjacent the proximal end and a distal surface adjacent an intermediate region of the hub passage; a side port comprising a first end coupled to an outer surface of the tubular body adjacent the intermediate region, a second outer end, and a port passage extending between the second end and the first end and communicating with the intermediate region of the hub passage; and a guide element in the side port adjacent the first end for directing fluid introduced into the second end through the port passage towards the distal surface of the valve.

In some examples, a delivery device includes a handle, a catheter sheath defining a lumen and extending distally from the handle, and a hemostasis valve positioned at least partially within the handle, the hemostasis valve being located proximal the catheter sheath, the hemostasis valve including a first seal and a second seal, and a first flush-port disposed between the first seal and the second seal.

Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example method for assembling a hemostasis valve may include positioning a plunger along a threaded proximal end region of a main body. The threaded proximal end region may include one or more threads and an axial slot extending through the one or more threads. The method may also include advancing the plunger along the threaded proximal end region to a position where a proximal end of the plunger is disposed distally of at least a portion of the one or more threads and disposing a nut adjacent to the threaded proximal end region. The method may also include aligning an alignment tab of the nut with the axial slot, engaging the nut with the one or more threads while the alignment tab is aligned with the axial slot, and rotating the nut 45-270.

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.

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. The cartridge may have one or more projections formed thereon. The proximal end region of the main body may have one or more recesses formed therein. The one or more recesses may be designed to engage the one or more projections. A plunger may be coupled to the proximal end region of the main body.
