    摘要： An enhanced catheter introducer and method for making the same are disclosed. The catheter introducer may have a splittable sleeve assembly configured to be inserted into a blood vessel with a cannula. The cannula may then be removed, and a catheter may be inserted into the sleeve assembly. The sleeve assembly may be removed from the catheter by pulling handles of the sleeve assembly in different directions to split the sleeve assembly into two pieces. The sleeve assembly may have failure zones that enable the sleeve assembly to be easily split; the failure zones may take the form of thinned regions running along the length of the sleeve assembly. The sleeve assembly may be injection molded with a single step by injecting flows of molten plastic into a cavity of a mold such that the flows converge into an even distribution about the circumference of the sleeve. The mold may have a core pin designed to fit into the cavity. Through the use of the even distribution of flows, the core pin may seat within the cavity in an untensioned manner.

    摘要翻译： 公开了一种增强导管引导器及其制造方法。 导管导引器可以具有被配置成用插管插入血管的可分开的套筒组件。 然后可以移除套管，并且可以将导管插入套筒组件中。 可以通过沿着不同方向拉动套筒组件的手柄将套筒组件从导管中移除，以将套筒组件分成两部分。 套筒组件可以具有使得套筒组件容易分裂的失效区域; 故障区域可以采取沿套筒组件的长度延伸的变薄区域的形式。 套筒组件可以通过将熔融塑料流注入模具的空腔中，通过单个步骤注塑成型，使得流动汇集成围绕套筒圆周的均匀分布。 模具可以具有设计成适合于空腔的芯销。 通过使用均匀的流动分布，芯销可以以未张紧的方式安置在空腔内。

    摘要： A delivery wire assembly for delivery of an occlusive device to a location in a patient's vasculature includes a delivery wire conduit having a proximal tubular portion coupled to a distal coil portion, the respective tubular and coil portions defining a conduit lumen. A core wire is disposed in the conduit lumen and having a distal end coupled to an occlusive device, wherein an elongate electrical contact body at least partially seated in the conduit lumen and coupled to a proximal end of the core wire, the electrical contact body and the proximal tubular portion forming a junction. A coil collar is disposed around the electrical contact body near the junction

    摘要： An occlusive coil delivery system includes a delivery wire having a distal end coupled to an occlusive device via an electrolytically severable junction, and an electrical contact secured to a proximal end of the delivery wire, which has a non-linear configuration so as to strengthen a mechanical connection with the electrical contact and/or increase electrical conductivity with the electrical contact over a linear configuration. The configuration may be, by way of non-limiting examples, a “U” shape, a spiral, a knot, or a twisted wire. The electrical contact is a conductive material that substantially envelopes the proximal end configuration of the delivery wire.
