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).
摘要翻译：公开了一种用于导管或护套的主体（2）。主体（2）包括从主体（2）的近端（6）部分到主体（2）的远端部分（4）纵向形成的条带（8,10）。条带由不同的材料形成。条带可以具有不同的放射性，或者可以是可分离的/可剥离的。可分离/可剥离的主体包括沿其相应长度纵向延伸的剥离机构。剥离机构可以通过在第一和第二纵向延伸的聚合物材料条之间的纵向延伸的界面结合区形成。应力集中区域沿着界面粘合区域延伸。应力集中有助于主体（2）沿其剥离机构的分裂。第一条带（8）的聚合物材料可以具有比第二条带（10）的聚合物材料更大量的不透射线填料。每个条形成主体（2）的外周表面的至少一部分。

摘要： The present invention is a splitable/peelable reinforced flexible tubular body (10) for a catheter or sheath (12). The body (10) comprises a proximal end (14), a distal end (16), a wall structure (18), and a lumen (20) defined by the wall structure (18). The wall structure (18) extends between the ends and includes a reinforcement layer (22) within the wall structure (18) and a separation line (26) extending longitudinally along the wall structure (18) . The separation line (26) is adapted to facilitate the splitting/peeling of the wall structure (18) to allow a medical device such as a pacemaker lead to be removed from within the tubular body (10).

摘要： An ablation catheter (10) is provided for ablating internal tissue of a patient. The catheter includes a distal end that is adapted to be inserted into a body cavity relative to a desired location therein (e.g., within the heart). An ablation electrode (22) is connected relative to the distal end of the catheter (10) for providing ablation energy to patient tissue. A heat sink (40) is provided that is in thermal contact with the ablation electrode (22). The heat sink (40), in addition to being in thermal contact with the ablation electrode (22), is electrically isolated from the ablation electrode (22). This allows the heat sink (40) to conduct heat away from the ablation electrode (22) without dissipating electrical energy from the electrode (22). In this regard, the heat sink (40) may prevent build-up of excess heat within the electrode (22) that may result in blood coagulation and/or tissue charring.
摘要翻译：提供消融导管（10），用于烧蚀患者的内部组织。该导管包括适于相对于其中的期望位置（例如，在心脏内）插入体腔中的远端。消融电极（22）相对于导管（10）的远端连接，用于向患者组织提供消融能量。提供与消融电极（22）热接触的散热器（40）。除了与消融电极（22）热接触之外，散热器（40）与消融电极（22）电隔离。这允许散热器（40）将热量从消融电极（22）导出，而不会从电极（22）中消散电能。在这方面，散热器（40）可防止可能导致血液凝固和/或组织烧焦的电极（22）内的过多热量的累积。
