摘要： Catheters having an overmolded hub are disclosed. The overmolded catheter hubs may include one or more access hubs that are overmolded with an overmold material. The catheter hub may also be formed as a single piece from the overmold material. The overmolded construction can result in a stronger bond between the catheter body and the hub and can provide for access hubs having sufficient clarity for the observation of air bubbles in a contained fluid. The disclosed catheter hubs may also demonstrate improved balloon deflation rates when utilized with a catheter body having a distal balloon.
摘要翻译：公开了具有包覆成型毂的导管。包覆成型的导管套管可以包括一个或多个通过包覆成型材料包覆成型的接入轮毂。导管座也可以从包覆成型材料形成为单件。包覆成型的结构可以导致导管主体和轮毂之间的更牢固的结合，并且可以提供具有足够透明度的接近轮毂，用于观察容纳流体中的气泡。当与具有远端气囊的导管主体一起使用时，所公开的导管套还可以显示改进的气囊放气速率。

摘要： A disposable access sheath having a deflectable tip is provided. The access sheath is very flexible and allows a physician or other medical professional to provide diagnostic or therapeutic services to a remote body cavity. The access sheath has a deflectable tip that is able to bend at least 90° or 180° or more. This flexibility allows the physician or medical professional to make a very tight turn to visualize or treat the body cavity being treated. The access sheath may include a visualization system, a working channel, an irrigation channel, or other desirable features. The access sheath may include an interface at the proximal end of the working channel for insertion of an instrument for diagnosis or treatment of a human or mammalian patient.
摘要翻译：提供具有可偏转尖端的一次性进入护套。进入护套非常灵活，允许医师或其他医疗专业人员向远程体腔提供诊断或治疗服务。进入护套具有能够弯曲至少90°或180°或更大的可偏转尖端。这种灵活性允许医师或医疗专业人员进行非常紧的转弯，以可视化或治疗正在治疗的体腔。进入护套可以包括可视化系统，工作通道，灌溉通道或其它期望的特征。进入护套可以包括在工作通道的近端处的接口，用于插入用于诊断或治疗人或哺乳动物患者的器械。

摘要： A large diameter, flexible, kink-resistant and rotatable introducer sheath (10) for percutaneous delivery of a contained and implantable medical device in the vasculature of a patient. The introducer sheath includes a reinforcement such as a flat wire coil (23) fitted about an inner, lubricous material such as polytetrafluoroethylene tube (22). A wire braid (25) is placed around the coil to give good transfer of rotational forces. An outer tube (27) of a heat formable polyamide material is heat formed and compressed through the spaces between the wires of the braid and turns of the wire coil to mechanically connect the outer tube to the roughened outer surface of the inner tube. The durometer of the outer tube can be varied to effect the flexibility of the sheath. A radiopaque marker (42) is positioned at the distal end of the coil and around the inner tube for radiographic visualization.

摘要： A medical device (110) including a catheter shaft (111) and a unitarily and continuously formed portion (108) having a varying durometer, and optionally including an expandable balloon (18, 118). One or both of the unitarily and continuously formed portion (108) and the balloon (18, 118) are made from an irradiation cross-linked or cross-linkable mixture of a polyamide elastomer and at least one additional cross-linking reactant. The polyamide elastomer can be a polyester amide, a polyether ester amide or a polyether amide, and is preferably a nylon block copolymer. The aromatic molecule can be 1,3,5 triethyl benzene; 1,2,4 triethyl benzene; and 1,3,5 triisopropyl benzene. The cross-linking reactant can be: (a) a difunctional material, (b) a trifunctional material, (c) a tetrafunctional material, or (d) an aromatic molecule containing at least two ring substituents, each of the ring substituents having labile hydrogens at a benzylic site therein. The cross-linking reactant can also be diallyl phthalate or meta-phenylene dimaleimide.
