    摘要: A low profile inflation valve located inside a balloon catheter that enables a user to inflate the balloon and exchange other medical apparatus over the catheter while the balloon remains inflated.The low profile inflation valve of the present invention includes a first tube having a lumen and at least one region of decreased inner diameter, and a structure movably located inside the lumen of said first tube, wherein said region of decreased inner diameter of said first tube forms a seal with a portion of said structure. The present invention further includes a method of making a low profile inflation valve using a first and second tube comprising the steps of creating an aperture in at least one side of a second tube, placing the second tube inside a first tube, the first tube being made of thermoplastic material, applying heat to a localized area of the first tube, and compressing the first tube to form a region of reduced internal diameter, the reduced diameter forming a seal with the outside diameter of the second tube.

    摘要: A guide wire for magnetically navigating a medical device through in a subject's body comprising an elongate wire having a proximal and distal end, a portion adjacent the distal end that is more flexible than the more proximal portions of the elongate wire, and a first magnetically responsive element on the distal end of the elongate wire. The guide wire further comprises one or more magnetically responsive elements spaced apart from the first magnetically responsive element and disposed on the more flexible portion of the elongate wire. The guide wire provides for bending or deflecting the distal end of the stent, to provide easier navigation of the distal end of the guide wire and the stent through the vasculature of a subject body.

    摘要: A balloon catheter which has an elongate shaft with an inflatable balloon connected to its distal end and a manifold connected to its proximal end. The manifold may be fixedly or removably attached to the shaft and includes a barrel with a plunger movably disposed inside it. The barrel has an internal volume of less than 5 cc and an internal diameter of less than 0.25 inches. A pressure transducer may be mounted to the manifold to permit measurement via a sensor tube. A pressure source for a balloon catheter including a barrel with a plunger inside it. The barrel is in fluid communication with the inflation lumen of the catheter and has an internal volume less than 5 cc and an internal diameter of less than 0.25 inches. A pressure sensor may be connected to the barrel with a sensor tube defining a fluid path from the interior of the barrel to the pressure sensor. A lock mechanism may be connected to the barrel to control longitudinal movement of the plunger. Pressure sources for balloon catheters with an adjusted P/&Dgr;V of 4000 atm/cu.in. or more and preferably 6000 atm/cu.in. or more over a pressure range of 5 to 15 atm. Connection tubes for connecting a pressure source to a balloon catheter with an adjusted P/&Dgr;V of 6000 atm/cu.in. or more (or an adjusted P/&Dgr;V by unit length of 90×103 atm/sq.in. or more) and preferably 8000 atm/cu.in. or more (or an adjusted P/&Dgr;V by unit length of 110×103 atm/sq.in. or more) over a pressure range of 5 to 15 atm.
