Abstract: A slitter for slitting a guide catheter has a handle and a blade assembly coupled to the handle. The blade assembly includes a shroud for receiving an elongated body of a medical device and a slitting blade having an exposed cutting edge to slit the guide catheter. The blade assembly includes a user-deflectable portion coupled to the shroud for causing the shroud to flex in response to deflection of the user-deflectable portion. The handle and the blade assembly may be assembled from piece parts in a manufacturing method.

Abstract: A catheter has a shaft that defines a delivery lumen, for example, to deliver an elongate medical device therethrough; a proximal section of the catheter includes a seal zone portion, a handle portion and a proximal port portion. A relatively thin wall section of the proximal port portion extends between the seal zone portion and a proximal edge that defines part of a perimeter of a proximal opening of the delivery lumen. The handle portion projects laterally from the seal zone portion, generally opposite the relatively thin wall section. An inflation subassembly of the catheter includes a compliant sleeve member and an inflation lumen extending from the sleeve member, proximally along the shaft, and into a connector port formed in the handle portion. The inflation lumen may be formed by fusing a section of a tube to the shaft and molding the handle portion around another section of the tube.

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。
