摘要： A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. One method for curving a catheter tube of a catheter assembly includes constraining the catheter tube into a curved configuration using the tube constraint, heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature, and releasing the catheter tube from the tube constraint after the heating is complete.

摘要： A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. In one embodiment, therefore, a catheter assembly is disclosed, comprising an elongate catheter tube defining at least one lumen, and a tube constraint. The tube constraint is included with the catheter assembly and is configured to temporarily constrain the catheter tube in a curved configuration during a heating procedure of the catheter assembly so as to permanently form the catheter tube in the curved configuration after the heating procedure is complete and the catheter tube is released from the tube constraint.

摘要： An insertion device for inserting a catheter into a patient's body is disclosed. The insertion device combines needle insertion, guidewire advancement, catheter insertion, and needle shielding in a single device. In one embodiment, the insertion device comprises a housing including a hollow needle distally extending from the housing. At least a portion of the catheter is pre-disposed over the needle such that the catheter is disposed substantially external to the housing. A guidewire is included, as well as an advancement assembly that is configured to selectively advance the distal end of the guidewire out a distal opening of the needle in preparation for distal advancement of the catheter. The advancement assembly is further configured to enable distal catheter advancement before shielding the needle after use. The insertion device is configured to be grasped and used by a single hand of a user during advancement of the guidewire and the catheter.
摘要翻译： 公开了一种用于将导管插入患者体内的插入装置。 插入装置将针插入，导丝推进，导管插入和针屏蔽结合在一个装置中。 在一个实施例中，插入装置包括壳体，该壳体包括从壳体向远侧延伸的中空针头。 导管的至少一部分预先设置在针上，使得导管基本上设置在外壳的外部。 包括导丝，以及推进组件，其被配置为选择性地将导丝的远端推出针的远侧开口以准备导管的远端前进。 前进组件还被构造成在使用后屏蔽针之前能够使远端导管前进。 插入装置构造成在导丝和导管的推进期间被使用者的单手抓住并使用。

摘要： An insertion device for inserting a catheter into a patient's body is disclosed. In some embodiments, the insertion device combines needle insertion, guidewire advancement, catheter insertion, and needle shielding in a single device. In one embodiment, the insertion device comprises a housing including a hollow needle distally extending from the housing. At least a portion of the catheter is pre-disposed over the needle such that the catheter is disposed substantially external to the housing. A guidewire is included, as well as an advancement assembly that is configured to selectively advance the distal end of the guidewire out a distal opening of the needle in preparation for distal advancement of the catheter. The advancement assembly is further configured to enable distal catheter advancement before shielding the needle after use. The insertion device is configured to be grasped and used by a single hand of a user.
