A catheter assembly may include a catheter adapter. A body of the catheter adapter may include a distal end, a proximal end, and a first lumen extending through the distal end and the proximal end. The catheter adapter may include a side port, which may extend outwardly from the body. The side port may include a second lumen, which may be perpendicular to the first lumen. The catheter assembly may include a catheter extending distally from the distal end of the body. The catheter assembly may include a valve disposed within the first lumen. The valve may include an outer surface that is cylindrical and may seal the first lumen from the second lumen. The catheter assembly may include a divider disposed with the second lumen. The divider may divide the second lumen into a plurality of openings and may increase a burst value of the valve.

A rapid exchange catheter and an associated method of forming a port joint for a rapid exchange catheter are disclosed. The catheter includes an elongate shaft, a catheter hub disposed at the proximal end of the elongate shaft, and a guidewire port formed within the elongate shaft at a position distal of the proximal end of the elongate shaft and proximal of the distal end of the elongate shaft. A core wire extends past the guidewire port and includes a distal end region secured to the elongate shaft distal of the guidewire port by virtue of one or more components of the elongate shaft being reflowed around the core wire during manufacture of the rapid exchange catheter.

The present invention relates to a catheter and a process for manufacturing a radially extending opening in tubing for a catheter. The tubing having at least one lumen being enclosed by at least one tubing wall and the process comprises placing tubing in a fixture, applying force to the tubing and thereby fixing the tubing in the fixture in a position for making an opening, pressing a heated depression tool against the surface of the tubing creating a depression area in the at least one tubing wall, and punching an opening cutting tool through the at least one tubing wall within the depression area creating an opening in the depression area of the at least one tubing wall, the opening extending from the exterior of the tubing to the lumen of the tubing.

A catheter or shaft, such as a distal access support or aspiration catheter, is provided that is configured to be advanced at least partially within a patient. The catheter or shaft may include a flexible and hollow shaft including a proximal end and a distal end. The flexible and hollow shaft may include a slotted portion with a plurality of slotted openings, the slotted portion including a first segment with a first pattern of slotted openings and a second segment extending proximally relative the first segment with a second pattern of slotted openings different from the first pattern.

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.

An object of the present invention is to provide a method of joining resin tubes, in which the degree of freedom of selecting a tube material is large, and further a defect such as stiffness and contraction at joining portions of the tubes is not developed. The method of joining resin tubes according to the present invention is a method of joining resin tubes so that a first tube is joined to a second tube, the first tube and the second tube each being made of synthetic resin, the method comprising: a surface activation step of activating each of a joining region of the first tube and a joining region of the second tube; and an adhesion step of adhering the joining region of the first tube obtained via the surface activation step with the joining region of the second tube obtained via the surface activation step to each other.

A medical catheter includes: a sheath having a guide wire lumen through which a guide wire is passed and a guide wire port formed in an outer peripheral surface, the guide wire port communicating with the guide wire lumen; a sloped portion that is a portion of the sheath dropped into the guidewire lumen, the sloped portion being provided continuously from an inner wall of the guide wire lumen through the guide wire port to the outer peripheral surface; and a reinforcing portion that is a portion of the sheath softened or melted to be deformed by heating, the reinforcing portion being provided to a proximal end side of the sloped portion in the guide wire lumen, wherein a height of the reinforcing portion is 30% or more of an inner diameter of the guide wire lumen.

A venous catheter having a catheter tip comprising recessed diffusion holes for increasing the snag-resistance of the venous catheter. The invention further provides systems and methods for providing axial ridges interposed between diffusion holes for increasing the rigidity of the vented catheter tip.

An intravascular heart pump assembly can include a rotor with at least one impeller blade, and a cannula. The present application describes various cannulas that can be manufactured from multiple layers of material to improve flexibility, manufacturability, and durability without increasing an outer diameter of the cannula. In one embodiment, the cannula includes an inflow section having a sheet formed of a shape memory material embedded within a polymer and having at least one lateral hole or aperture in the inflow section. The at least one lateral hole is defined by a first hole in the sheet and a second hole in the outer polymer layer of the cannula. The first hole and the second hole overlap so that blood can enter the cannula through the holes.

The inventive method for making a medical device includes providing a micro plastic tube; molding a hub onto the tube; trimming the tube to a predetermined length; molding a tip onto the tube, and creating a tip that contains a micro orifice at a predetermined angle.
