An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature protruding outwardly from the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

A hub assembly for connection to a medical device having a built in strain relief. The hub assembly may comprise a hub body having a proximal end and a distal end. A lumen may extend from the proximal end to the distal end of the hub body. The distal end of the hub body may have a rounded surface. The rounded surface may have a radius of curvature of greater than 1 millimeter.

In various examples, a hub for a medical device includes a hub housing including a passage from a proximal end of the hub housing to a distal end of the hub housing. A valve is disposed within the hub. The valve is configured to allow passage of an insertable device through the valve while inhibiting leakage of fluid from the valve. A cap is engaged to the hub housing. The cap includes an opening therethrough sized and shaped to allow passage of the insertable device through the opening. The opening allows access to the passage of the hub housing. An angled sidewall is disposed within the hub. The angled sidewall is configured to retain and deform the valve into a curved shape.

An introducer sheath is disclosed, which includes a tube body that is percutaneously inserted into a body lumen; and a hub that is connected to a proximal portion of the tube body. The tube body contains a polyvinylidene fluoride resin, a ratio of a thickness to an inner diameter of the tube body is 1/16 or lower, and a ratio of a kink radius to an outer diameter of the tube body is 9.5 or lower.

An introducer sheath and method are disclosed capable of reducing a physical burden on a patient by shortening a time necessary for hemostasis at an introduction part after removing the introducer sheath percutaneously introduced into a body lumen. The method of indwelling an introducer sheath in a body lumen includes: puncturing a body lumen in which an introducer sheath needs to be indwelled; and introducing an introducer sheath into a puncture site of the body lumen, the introducer sheath including a catheter main body having a portion provided with a thrombus inducing material and a hub, which is connected to a proximal side of the catheter main body, and wherein the catheter main body is indwelled in the body lumen while a part of the portion provided with the thrombus inducing material is inserted into the body lumen through the puncture site.

A protective sleeve for a urinary catheter includes a sleeve configured to extend over an outer surface of the urinary catheter shaft from a proximal insertion end of the catheter shaft to a distal end of the catheter shaft. The protective sleeve includes a protective sleeve tip defining the proximal end portion of the sleeve. The sleeve and the protective sleeve tip are of a single unitary construction and the sleeve and protective sleeve tip are formed of the same thin, flexible film. The protective sleeve tips has a first pre-use configuration when a proximal insertion end of the catheter is not within the protective sleeve tip wherein the protective sleeve tip is in a collapsed state, and a second configuration when a proximal insertion end of a urinary catheter is inserted into the protective sleeve tip, in the second configuration the protective sleeve tip being in an extended state that is configured to cover the proximal insertion end of the urinary catheter shaft and the thin, flexible film conforms to and is supported by the proximal insertion end of the urinary catheter for insertion of the protective sleeve tip into the urethral opening.

Methods and devices related to fluid delivery catheters and more particularly relates to catheters used to deliver fluid to medical devices and/or position medical devices.

A medical device includes an elongate shaft including a multifilar coil comprising a first strand and a second strand wound in the same winding direction, the multifilar coil comprising a first section having a first end and a second end wherein the first strand and the second strand are wound with identical pitch patterns between the first end and the second end of the first section, the multifilar coil further comprising a second section having a first end and a second end, wherein the first strand and the second strand are wound with different pitch patterns from each other between the first end and second end of the second section, and a polymeric tubular member coextending with the multifilar coil.

A catheter assembly may include a catheter adapter, which may include a body and a nose extending distally from the body. The nose may be generally cylindrical. A strain relief rib may be disposed on the nose. The strain relief rib may be constructed of a flexible material. The catheter assembly may also include a needle secured within the catheter adapter and extending distally beyond the nose. The catheter assembly may further include a needle cover, which may be removably coupled to the nose of the catheter adapter. An inner surface of the needle cover may be smooth and may contact the strain relief rib.

A ready-to-use urinary catheter assembly (20) includes a catheter (26) comprising a shaft (28) having a proximal insertion end (30) and a distal end (32) spaced from the proximal insertion end. The assembly also includes a protective sleeve (54) including a protective sleeve tip (36) being configured to cover the proximal insertion end of the catheter shaft as the proximal insertion end of the catheter shaft is inserted into a distal portion of the urethra. The proximal insertion end (30) of the catheter shaft (28) is advanced proximally to rupture the protective sleeve tip (36) and to be advanced through the remainder of the urethra.
