    摘要： An integrated inflation/deflation device provides easy, precise delivery of a small amount of fluid for proper inflation of a low volume surgical balloon and similarly provides easy and fast deflation of the balloon. A preferred embodiment includes a low volume syringe and large syringe mounted together within a housing. A port in the low volume syringe is in communication with the large syringe barrel. The low volume syringe plunger is controlled by a knob disposed on the housing. The large syringe is used to prime the surgical balloon system, including a catheter, and the low volume syringe delivers a precise, predetermined volume of fluid to inflate the balloon. The low volume syringe is also used to deflate the balloon. Preferably, indicia on the housing adjacent the knob direct the required rotation of the knob to deliver the correct volume of fluid to be injected to match a balloon of a given size and shape so that the balloon is properly inflated.

    摘要： Disclosed herein is an improved core wire for use in a medical catheter. In one aspect, a tapering core wire is incorporated into the distal end of a catheter. The catheter has a tubular body. Both ends of an inflatable balloon are mounted to the tubular body. The core wire extends from the distal end of the tubular body. In one embodiment, substantially all of the taper of the core wire occurs in the extending portion of the core wire over a length of at least 15 mm but no more than 60 mm. In another aspect, a core wire with a shapeable tip and method of manufacturing the same are provided. A core wire previously made superelastic is subject to additional processing to remove its superelasticity thereby allowing the material to be shapeable to aid in advancing the core wire through a blood vessel or other body cavities. In another aspect of the present invention, a method is provided for securing the core wire to the distal end of an elongated catheter tubular body. The tubular body is mechanically crimped onto the core wire to secure the core wire in place. This crimping method has been found to increase the strength of the bond between the core wire and the catheter tube so that greater pull force is required to break the core wire off from the catheter.

    摘要： A stent positioning apparatus and method are provided for the attachment of a stent to a balloon to be used in the treatment of stenosis, such as coronary angioplasty. In one preferred embodiment, a first generally cylindrical member has a radially deformable wall defining a channel within which the stent and balloon assembly are inserted. A second generally cylindrical member has an opening sufficient to receive the first member with the assembly therein. The second member is then slid longitudinally over the deformable wall of the first member causing nonuniform depressions to be formed in the inner diameter of the stent, thus crimping the stent onto the balloon. Thus, the stent is attached to the balloon without damage and without risk of the stent falling off the balloon prematurely.
