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.

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.

An external protective interface is provided for intravenous infusion lines, drive lines, vacuum lines, and monitoring lines for percutaneous access. The interface acts as an airtight seal in concert with a vacuum line to promote accelerated tissue healing to reduce and prevent infection at insertion sites for infusion lines, drive lines, and medical devices. The interface provides additional mechanical stability to an implanted tube or PAD or so as to speed healing around a semi-permanent implanted tube or PAD, as well as connection points for vacuum lines and at least one drive line for the insertion of medical devices. The dense fibroblast ingrowth encouraged by the interface acts to strengthen barriers to infection at the insertion site.

A luer device includes Connector with a body and a lumen and Clip with exterior and interior portions. The body includes a distal portion to be coupled to cannula and a proximal portion to slidably receive a medical device. The exterior portion extends along longitudinal Axis from proximal to distal ends and includes a channel. A longitudinal slot extends along the exterior portion so that the channel is open to and in communication with a clip exterior via the slot. The interior portion extends along an interior surface of the channel defining jaws and formed of a material which, when Clip is moved from open toward closed configurations, in an operative position, is pressed against the device and Connector to seal a proximal end of Connector and direct fluid distally therethrough and through a space extending between an interior surface of cannula and an exterior surface of the device.

A sheath with an expandable and reducible diameter includes a body having a lumen and that is movable between a first configuration and a second configuration. The body has a first diameter size in the first configuration that is smaller than a second diameter size in the second configuration. The body includes a shaft made from a first material and a wire made from a second material.

An introducer sheath system comprising including a gasket disposed around an outer surface of a dual layered sheath. The gasket providing a radially inward force on the sheath to seal the sheath an outer layer of the sheath against an inner layer to prevent fluid flow therebetween.

A clip used in a catheter assembly, the clip comprising a first leg and a second leg angularly connected to the first leg, wherein the second leg includes a substantially U-shaped spade configured to engage a needle housing of the catheter assembly to secure the clip to the needle housing.

Devices, systems, and methods for sealing medical devices, particularly during intravascular access, are disclosed herein. Some aspects relate to a hemostatic valve for sealing a wide range of medical devices, such as catheters, wires, embolectomy systems. The valve can include an elongate member having a first end, a second end, and a central lumen extending therebetween. A reinforcement structure extends along at least a portion of the elongate member and is coupled to the elongate member. A shell defining a first aperture and a second aperture may be included, which first and second apertures can be fluidly coupled by the elongate member. A tensioning mechanism is coupled to the shell and to the elongate member, the tensioning mechanism can be moveable between a first configuration wherein the tensioning mechanism is collapsed and the central lumen is sealed and a second configuration wherein the central lumen is open.

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, 41a) 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).

Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a proximal end region. A cartridge may be at least partially disposed within the proximal end region. The cartridge including a seal member. The cartridge may have a proximal member, a distal member, and may define a seal holding region. The seal member may have an axial thickness of about 0.04 to about 0.2 inches. The seal member may be secured within the seal holding region by a mechanical bond.
