Abstract: A catheter proximal section is preferably formed from a relatively soft part and a relatively rigid part, and includes a proximal terminal end that defines a perimeter of an opening into a lumen of the catheter. The proximal section may further include a feature for interlocking engagement with an accessory tool. An inner surface of each of the relatively soft and rigid parts may be located opposite one another, on either side of the catheter lumen. The relatively soft and rigid parts may be included in a sealing assembly that further includes an attachment feature for removable connection of the assembly to the proximal section catheter.

Abstract: A syringe adapter tool facilitates inline connection of a syringe with a catheter lumen, as well as torque transfer between the syringe and catheter. The adapter tool may further facilitate passage of an instrument through a seal zone portion of the catheter lumen, which seal zone portion is located in a proximal section of the catheter.

Abstract: A proximal terminal end of a proximal section of a catheter, preferably tapered, defines a perimeter of an opening into a lumen of the catheter and includes an exposed sealing area. A sealing assembly, that may be removed from the catheter, includes a relatively soft part and a relatively rigid part, wherein the exposed sealing area is formed by the soft part, and the relatively rigid part may include an attachment feature for removable connection of the assembly to the catheter. The lumen of the catheter, within the proximal section, may include a seal zone portion, which preferably includes a slit segment intersecting a funnel-like segment of a bore. The catheter proximal section may further include a feature for interlocking engagement with an accessory tool.

Abstract translation: 导管的近端部分的近端终端优选为锥形，限定了进入导管内腔的开口的周边，并且包括暴露的密封区域。 可以从导管移除的密封组件包括相对柔软的部分和相对刚性的部分，其中暴露的密封区域由柔软部分形成，并且相对刚性的部分可以包括用于可拆卸地连接 组装到导管。 在近端部分内，导管的内腔可以包括密封区段，其优选地包括与孔的漏斗状区段相交的狭缝段。 导管近端部分还可以包括用于与附件工具互锁接合的特征。
