Abstract: A hub assembly and methods of attaching the same to a catheter shaft. The hub assembly includes a strain relief coupled to a hub. The strain relief may be mechanically coupled to the hub. The hub assembly may be manufactured in a non-clean room environment, and subsequently connected to the catheter shaft in a clean room.

Abstract: Medical devices, for example, those that have balloons, and methods of making the devices are described. In some embodiments, a method includes providing a medical balloon having a first cone portion and a body portion, and removing material from an outer surface the body portion of the balloon such that the balloon includes a first region and a second region, the first region being recessed relative to the second region.

Abstract: A treated medical device is provided. This medical device may be a stent and may have been treated by placing it into a treatment chamber, creating a buffer zone of compressible fluid between the medical implant and the inside surface of the treatment chamber, and applying a treatment to the medical implant when the medical implant is at least partially positioned within the treatment chamber. When the treatment is applied to the medical implant this may include forcing therapeutic out of an injection nozzle and towards the medical device. In some instances the buffer zone of compressible fluid may cause the medical implant to rotate about a longitudinal axis in a first direction when the medical implant is at least partially positioned within the treatment chamber.

Abstract: Apparatus and method for treating medical implants are provided. The apparatus may include a vessel having a treatment chamber with an inside surface, an outside surface, an entrance, a plurality of fluid passages passing from the outside surface to the inside surface, and a compressible fluid supply line coupled to at least one of the fluid passages. In this embodiment, passages may be positioned and sized to create a buffer zone of compressible fluids between the inside surface of the treatment chamber and a medical implant placed therein. The method may include placing a first medical implant into a treatment chamber having inside surfaces, retarding the first medical implant from contacting the inside surfaces of the treatment chamber by injecting compressible fluid into the treatment chamber, injecting a therapeutic into the treatment chamber, and removing the first medical implant.

Abstract: A method of making a medical device includes positioning a tool within a lumen of an elongated workpiece and discharging electric current across a gap between the tool and the workpiece to remove a portion of the workpiece.

Abstract: The present invention is directed to distal tip designs for catheter, wherein distal tip material is positioned about an inner shaft. The distal tip material may also be used as a tie layer for thermally bonding two incompatible materials together, such as a waist portion of a balloon to the inner shaft.
