摘要： A body (2) for a catheter or sheath is disclosed. The body (2) includes strips (8, 10) formed longitudinally from the proximal (6) portion of the body (2) to the distal (4) portion of the body (2). The strips are formed of different materials. The strips can have different radiopacities, or can be splittable/peelable. The splittable/peelable body comprises a peel mechanism longitudinally extending along its respective length. The peel mechanism can be formed by longitudinally extending regions of interfacial bonding between first and second longitudinally extending strips of polymer material. A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the body (2) along its peel mechanism. The polymer material of the first strip (8) can have a greater amount of radiopaque filler than the polymer material of the second strip (10). Each strip forms at least a portion of an outer circumferential surface of the body (2).

摘要： A catheter assembly includes an inner liner made of flexible material and an outer layer having a steering mechanism. The steering mechanism includes at least one flat wire and a corresponding lumen through which the flat wire may travel. The steering mechanism may also include at least one pull ring to which the flat wires are attached. A layer of heat shrink material may encompass the outer layer. A braided wire assembly, which may have a braid density that varies along the length of the catheter, may also be provided in the outer layer. The overall cross-section of the catheter assembly is preferably substantially circular. A catheter shaft may include a plurality of segments of differing hardness characteristics. The outer layer typically comprises a melt processing polymer such that the catheter assembly may be laminated using heat.

摘要： The present invention is a handle for controlling the deflection of a distal end of a catheter body. The handle comprises a slide base, an adjustment knob, a first slide and a second slide. The slide base includes a first end, a second end, and a slide compartment longitudinally extending through at least a portion of the slide base. The adjustment knob is rotateably connected to the first end of the slide base and includes a hole extending through the knob, wherein at least a portion of an inner diameter of the hole includes an internal right thread and an internal left thread. The internal threads of the knob engage the threads of the slides. Consequently, in operation, rotation of the adjustment knob causes the slides to displace in opposite directions within the slide compartment and the distal end of the catheter body to deflect accordingly.

摘要： A catheter assembly (100) includes an inner liner (10) made of flexible m aterial and an outer layer (60) having a steering mechanism. The steering me chanism includes at least one flat wire and a corresponding lumen (42) throu gh which the flat wire may travel. The steering mechanism may also include a t least one pull ring to which the flat wires are attached. A layer of heat shrink (70) material may encompass the outer layer. A braided wire assembly (50), which may have a braid density that varies along the length of the cat heter, may also be provided in the outer layer. The overall cross-section of the catheter assembly is preferably substantially circular. A catheter shaf t (100) may include a plurality of segments (61, 62) of differing hardness c haracteristics. The outer layer typically comprises a melt processing polyme r such that the catheter assembly may be laminated using heat.

摘要： A splittable/peelable tubular body (2) of a catheter or sheath wherein the tubular body (2) has a splittable/peelable atraumatic tip (14) is disclosed. The atraumatic tip (4) is generally softer than the tubular body (2). The tubular body (2) and atraumatic tip (4) each comprise a peel mechanism longitudinally extending along their respective lengths. The peel mechanisms are formed by longitudinally extending regions of interfacial bonding (11) between first and second longitudinally extending strips (8, 10) of polymer material. Each strip (8, 10) forms at least a portion of an outer circumferential surface of the tubular body (2) and atraumatic tip (4). A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the tubular body (2) and atraumatic tip (4) along their respective peel mechanisms.
