A method, including incorporating a conducting wire into a tubular braid consisting of a multiplicity of supporting wires, and covering the tubular braid with a sheath. The method further includes identifying a location of the conducting wire within the tubular braid and attaching an electrode through the sheath to the conducting wire at the location.

A balloon catheter includes a one-piece extrusion having inner and outer tubular walls, where the inner tubular wall defines a wire guide lumen, and a clearance extending between the inner and outer tubular walls forms an inflation lumen. A balloon is attached to the outer tubular wall and to the inner tubular wall, such that the inflation lumen is in fluid communication with the balloon and the wire guide lumen extends through the balloon. A method of making the balloon catheter is also disclosed.

A method, including the operations of molding a hollow cannula to create flash on the cannula at parting lines of a mold, retaining the flash on the cannula, and installing the cannula with the flash in a medical device.

This catheter has: a shaft (10) has a first side hole (31) and a second side hole (32) in a wall (12); an insertion member (20) disposed in the lumen (11) of the shaft (10); a first electrode (41) provided on outer side of the first side hole (31); and a first wire (51) that is electrically connected to the first electrode (41) through the first side hole (31) and extents in the lumen (11) of the shaft (10) but outside the insertion member (20), wherein the first wire (51) has a first position (61) and a second position (62) inside the shaft (10), and the second position (62) of the first wire (51) is located at a position deviated from the first position (61) by 45 degrees or more in a circumferential direction of the insertion member (20).

A system and method for making cuts in a catheter or other medical tubing may include one or more blades connected to a blade housing. The blade housing may be attached to one or more mounting stems, and the mounting stems are coupled to a drive mechanism to axially rotate the blade housing and blade. A cradle plate is positioned proximal to the blade. The cradle plate includes a circular passageway extending therethrough non-parallel to the axis of rotation of the blade for holding medical tubing to be cut. The cradle plate also includes an arced cut-out in the axis of rotation of the blade to allow the blade to rotate into the arced cut-out to cut the tubing without colliding with the cradle plate.

A barbed microcatheter includes a hollow tube having an elongated lumen, outwardly projecting barbs, fluid egress openings, a tissue anchor secured to a proximal end of the hollow tube, and a needle secured to the distal end of the hollow tube. The needle is used to form a first tissue opening at the first end of the wound. The hollow tube is pulled through the first tissue opening until the tissue anchor abuts against tissue at the first end of the wound. The needle is used to form a second tissue opening at the second end of the wound. The hollow tube is pulled through the second tissue opening so that barbs engage wound tissue. After cutting away the needle, a therapeutic fluid is introduced into the elongated lumen and passes through the fluid egress openings for infusing the wound with the therapeutic fluid.

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.

A clot retrieval device is provided. The clot retrieval device includes a capturing basket having an opening at a proximal end where the capturing basket is deployable downstream from a clot in a blood vessel. The capturing basket is configured to surround a portion of the clot and the opening in the proximal end of the capturing basket is configured to reduce in size such that the capturing basket conforms around the portion of the clot and be retrieved after the capturing basket conforms around the portion of the clot.

The present application relates to a method for producing a catheter tube. The method including sucking gas from a second end 43 of a tubular body 40 while introducing pressurized gas into a lumen 41 of the tubular body 40 from a first end 42 of the tubular body 40, so that an internal pressure is applied to the lumen 41 of the tubular body 40 by introducing the pressurized gas, and the tubular body 40 is delivered in a direction from the first end 42 to the second end 43 by sucking the gas from the second end 43 of the tubular body 40.

A drug delivery device includes a blunt cannula and a reservoir. The blunt cannula has a cylindrical wall that defines an axial passage between a first end and a second end of the blunt cannula. The wall has at least a first tapered region at the first end to define an opening in fluid communication with the axial passage and adapted at the first end to resist interruption of fluid flow through the axial passage and out of the first end of the blunt cannula. The reservoir is connected to the second end of the blunt cannula.
