摘要： A dual braided catheter shaft includes a flat wire forming the inner braid, thereby potentially allowing for reduced radial thickness of the shaft. In one embodiment, the shaft (100) includes an inner polymer jacket (104), an inner braid (106) formed on the inner jacket (104), an intermediate jacket (108) formed over the inner braid (106), an outer braid (110) formed on the intermediate jacket (108) and an outer jacket (112) formed on the outer braid (110). A preferred construction process involves extruding polymer material directly onto each of the inner and outer braids (106 and 110) so that little or no air gaps remain between the polymer material and the braids (106 and 110). The braiding parameters of the inner and outer braids (106 and 110) can be varied along the length of the catheter to provide varying mechanical properties.

摘要： The present invention is a catheter actuation handle (14) for deflecting a distal end (18) of a tubular catheter body (12), the handle including an auto-locking mechanism, (54). The handle comprises upper and lower grip portions (24a, 24b), an actuator (20), and an auto-locking mechanism, (54). The auto-locking mechanism (54) is adapted to hold a deflected distal end (18) of the catheter (10) in place without input from the operator. When the distal end (18) of the catheter (10) is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator (20). The auto-locking mechanism (54) acts by providing a second force that resists this force from the distal end (18) and holds the distal end (18) in place. As a result, the operator does not need to maintain contact with the buttons (22a, 22b) to maintain the distal end (18) in a set position.
摘要翻译：本发明是用于偏转管状导管主体（12）的远端（18）的导管致动手柄（14），该手柄包括自动锁定机构（54）。手柄包括上和下抓握部分（24a，24b），致动器（20）和自动锁定机构（54）。自动锁定机构（54）适于将导管（10）的偏转的远端（18）保持在适当的位置，而没有来自操作者的输入。当导管（10）的远端（18）从其零位偏转时，通常将寻求返回其零位置，并且因此对致动器（20）施加力。自动锁定机构（54）通过提供抵抗来自远端（18）的该力并将远端（18）保持在适当位置的第二力来起作用。结果，操作者不需要保持与按钮（22a，22b）的接触，以将远端（18）保持在设定位置。

摘要： A catheter assembly (100) includes an inner liner (10) made of flexible material and an outer layer (60) having a steering mechanism. The steering mechanism includes at least one flat wire and a corresponding lumen (42) 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 (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 catheter, may also be provided in the outer layer. The overall cross-section of the catheter assembly is preferably substantially circular. A catheter shaft (100) may include a plurality of segments (61, 62) 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 instant invention relates to transseptal access systems and methods for accessing the left atrium (52) from the right atrium (48) by crossing the interatrial septum (50). In particular, the instant invention is directed toward medical devices used with catheter assemblies in cardiology procedures that require transseptal puncture(s). The puncture assemblies (e.g., 10) have a moveable puncture device (e.g., 14) within a dilator (e.g., 16). The puncture device is biased in a retracted position. The position of the puncture assembly is precisely locatable. The puncture assembly is preferably flexible along the majority of the length of its and, therefore, can be used with any catheter assembly of any predetermined shape. The puncture device is adjustable from a position within the dilator to a position extending beyond the end of the dilator when necessary for use in transseptal procedures.

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.

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).
