The present invention relates to a valve component for a medical valve assembly, the valve component comprising a deformable body for location in a valve assembly housing, the deformable body comprising a conduit for receiving one or more medical instruments there-through, one or more helical grooves being formed on a surface of the conduit, the one or more helical grooves extending into the deformable body from the conduit surface.

A medical device may include a seal portion having a first seal wall extending to a first lip and a second seal wall extending distally to a second lip that contacts the first lip, the first lip and second lip defining a slit, and a rim portion extending around the seal portion, the rim portion being curved or bent in a proximal direction.

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.

The present disclosure discussed a device, method and/or system for performing a sealing control for a vascular treatment system having a handle assembly. To perform the sealing control, a movable ring associated with the handle assembly is adjusted to at least one of: a first position to provide a minimum pressure seal between the catheter and the handle assembly such that the catheter is freely movable within the handle assembly, a second position to provide a predetermined amount of pressure seal between the catheter and the handle assembly such that the catheter is movable in frictional contact with the handle assembly, and a third position to provide a maximum pressure seal between the catheter and the handle assembly such that the catheter is unmovable within the handle assembly.

A hemostasis device includes a valve, the valve being sized and configured to be disposed entirely within a handle of medical device, the valve including a rim, the rim be sized and configured to seal with a lumen of the handle of the medical device.

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.

An integral seal system includes a body that defines a central opening, and an asymmetric seal extending into the central opening and including a diaphragm and an annular flange that extends between the body and the diaphragm, wherein the diaphragm has a cross-sectional thickness larger than a cross-sectional thickness of the annular flange. A duckbill seal extends distally from a bottom of the body and defines one or more parting lines that separate opposing seal flaps. The diaphragm complements insertion and extraction drag forces generated by the duckbill seal against a surgical tool shaft extended therethrough such that total insertion and extraction drag forces generated by the integral seal system are equalized.

A hemostasis valve assembly includes a hollow body delimiting an inner passage for inserting a medical material, the inner passage extending between a proximal opening and a distal opening of the hollow body, a distal seal arranged at the distal opening, a proximal seal arranged at the proximal opening, a spacer element arranged between the distal seal and the proximal seal, and an end cap. The distal seal is an elastic valve that is sealed when idle. The end cap has a fixing element engaging a support element of the hollow body to fix a stacked assembly including the distal seal, the spacer element, and the proximal seal inside the hollow body.

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.

A hemostasis or bleed-back control valve such as a Tuohy-Borst adapter is provided that is capable of sensing pressure in vivo. The valve may include a main valve body having a lumen. An upstream main seal may be disposed in the lumen of the main valve body. A catheter fitting may be disposed at a downstream end of the main valve body. A pressure transducer may be in fluid communication with the lumen of the main valve body. Such devices may be suitable for exploratory or interventional medicine involving catheterization.
