    Abstract: A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.

    Abstract: Balloon catheter comprises an elongate catheter shaft having a proximal section, a distal section, and an inflation lumen, and a multilayer balloon on the distal section of the shaft. The multilayer balloon comprises at least a first layer and a second layer having a combined wall thickness and an outer-most layer. The first layer is made of a first polymer material having a first maximum blow-up-ratio. The second layer is made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio and the second layer is an inner layer relative to the first layer. The at least first and second layers define a compliance less than that of a single layer balloon made of the first polymer material with a wall thickness equal to the combined wall thickness. The outer-most layer is made of a third polymer material.

    Abstract: An elongated guidewire for use in angioplasty and related procedures. The guidewire includes a proximal section and a distal section. The proximal section has a plurality of round cross-section segments alternating with a plurality of non-round cross-section segments. The non-round cross-section segments can include a square, rectangle, pentagon, triangle, octagon and polygon.

    Abstract: A shaping tool is used to form a bend in the distal end of a guidewire. The guidewire distal end is inserted through a channel and into a cavity of the shaping tool. Using hand pressure, a first member is moved axially relative to a second member of the shaping tool, thereby moving the cavity relative to the channel and imparting a bend in the distal end of the guidewire.

    Abstract: Multilayer balloon for a catheter includes at least a first layer, a second layer, and a third layer having a combined wall thickness. The first layer is made of a first polymer material having a first maximum blow-up-ratio. The second layer made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio, and the second layer is an inner layer relative to the first layer. The third layer is made of a third polymer material having a third maximum blow-up-ratio greater than the second maximum blow-up-ratio, and the third layer is an inner layer relative to the second layer. The at least first, second, and third layers define a compliance less than that of a single layer balloon made of the first polymer material with a wall thickness equal to the combined wall thickness. Method of making of multilayer balloon is also provided.
