A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip, a catheter hub (14) housing the catheter (22), 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 cover 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).

Catheter tube capable of irradiating laser optimized in light radiation efficiency and distribution, used in photosensitization reaction treatment is provided by simple process. Catheter tubes provided to medical device inserted into a living body to irradiate target site for treatment or examination with a light to treat or examine the site. The tubes being formed of material optically having transparency, provided with insertion hole for light diffusing body, and one or more other holes different from the insertion hole, in a manner extending in longitudinal direction of catheter tubes. Inside the other holes, space is present adjacent to inner wall thereof, the inner wall forming optical interface between the material and gas phase or liquid phase in the space, which are different from each other in refractive index, to conjointly form reflection surface for adjusting radiation distribution of light emitted by light diffusing body.

Unwinding a portion of a support helix that comprises a heating wire from a wall of a hose at an end of the hose; sleeving a length of heatshrink tubing at least partly onto the unwound portion of the support helix; heating the heatshrink tubing to shrink onto at least part of the unwound portion of the support helix; and at an end of the unwound portion, directly connecting the heating wire to an electrical contact of an electrical connector.

A catheter assembly includes a catheter shaft having shaft proximal and distal portions. A hub is coupled with the catheter shaft proximate the shaft proximal portion. A graduated strain relief fitting is coupled between the catheter shaft and the hub. The graduated strain relief fitting includes at least a first flexural modulus proximate the hub and a fitting proximal portion. The graduated strain relief fitting includes a second flexural modulus proximate the catheter shaft and a fitting distal portion. The second flexural modulus is less than the first flexural modulus and less than or equal to a catheter shaft flexural modulus. The first and second flexural moduli are modulated with one or more of a taper, flexure joints, fitting frame of the fitting or material of the fitting body.

A catheter assembly may include an adapter having a distal end, a proximal end, a side port, and an adapter lumen. The catheter assembly may include a catheter hub, which may include a distal end, a proximal end, a catheter hub lumen, and another side port. The catheter assembly may include an extension tube. A distal end of the extension tube may be coupled to the other side port, and the distal end of the adapter may be coupled to a proximal end of the extension tube. A fluidic seal may be formed around a tube of an instrument advancement device when the tube is advanced into the adapter. As an example, a portion of the adapter lumen between the distal end of the adapter and the side port may include an annular protrusion configured to form the fluidic seal.

An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

A catheter is configured to reduce a possibility that a shaft of a catheter inserted into a body comes off from a hub on a proximal side when a contrast agent is injected at a high pressure and the shaft is pulled out. The catheter includes a shaft and a hub that are directly fusion-bonded at a shaft accommodation portion of the hub that accommodates a proximal end of the shaft and a vicinity of the proximal end and a minimum inner diameter of the shaft accommodation portion is at any portion of the fusion surface. The shaft is thus prevented from coming off from the hub, safety of a worker is achieved without using an adhesive, a yield is further improved, and a manufacturing cost and a cost required for ensuring safety are reduced.

A catheter assembly includes a catheter, a catheter hub fixed to the catheter, an inner needle inserted through the catheter, and a grip that fixes and holds the inner needle. In addition, the catheter assembly includes a support structure portion that supports the outer side of the catheter. The support structure portion comes into contact with the catheter in an assembled state to deform at least one of the support structure portion and the catheter.

A catheter assembly includes: a catheter; a catheter hub fixed to the catheter; an inner needle inserted through the catheter; a grip that fixes and holds the inner needle; and a support structure portion that contacts an outer peripheral surface of the catheter at a contact position to support an outer side of the catheter in an assembled state. In the assembled state, the support structure portion presses the catheter at the contact position without clamping the catheter at the contact position, and thereby deflects the catheter so that the catheter is curved along an extending direction when viewed from a direction orthogonal to the extending direction.

A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip, a catheter hub (14) housing the catheter (22), 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 cover 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).
