The present disclosure is directed to a multi-segment device, such as an intravascular guide wire. The multi-segment device includes an elongate first portion comprising a first metallic material, an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end by a solid-state weld, and a heat affected zone surrounding an interface of the weld where the first and second portions are joined together, wherein the heat affected zone has an average thickness of less than about 0.20 mm.

A method of pretinning a guidewire core made of shape memory alloy and having an elongate axis, comprising: placing a ball of solder in a pocket in a soldering block; melting the ball of solder; holding a guidewire core over the ball of solder; lowering the guidewire core into the ball of solder; removing the guidewire from the ball of solder.

Medical device handle

A system for delivering an implant including a handle, a trigger, an actuation assembly, and a catheter assembly. The actuation assembly is configured to displace the outer tubular member in the proximal direction and to separately move the inner shaft member distally upon deployment of the trigger from the first position to the second position, and move the inner shaft member proximally with no displacement of the outer tubular member upon return of the trigger from the second position to the first position. The catheter assembly includes an outer tubular member, an inner shaft member, and a pusher assembly.

Methods and systems for delivering an implant

A system for delivering an implant including a handle, a trigger, and an actuation assembly. The actuation assembly can be configured to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and to separately move the inner shaft member distally a distance (x) relative to the handle upon deployment of the trigger from a first position to a second position, and move the inner shaft member proximally a distance (y) relative to the handle with no displacement of the outer tubular member upon return of the trigger from the second position to the first position.

A system for delivering an implant including a handle, a trigger, and an actuation assembly. The actuation assembly can include a planet carrier, at least one planet gear operatively coupled to the planet carrier, a sun gear shaft operatively engaged with the planet gear, a ring gear operatively engaged with the planet gear, a first clutch driver, and a second clutch driver. The actuation assembly can be configured to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and to separately move the inner shaft member distally a distance (x) relative to the handle upon deployment of the trigger from a first position to a second position, and move the inner shaft member proximally a distance (y) relative to the handle with no displacement of the outer tubular member upon return of the trigger from the second position to the first position.

A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a heat nozzle configured for applying a uniform drying gas. A coating process using the dryer includes a closed-loop control for the gas between drying steps and an improved nozzle for producing more consistent spray patterns.

Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member. A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.
