摘要： A catheter shaft and methods for making and using the same. The catheter shaft may include a core portion, a cap portion, and one or more lumens. The cap portion may be disposed on or over a section of the core portion and define a region with a different exterior or interior surface characteristic. For example, the cap portion may define a lubricious region along the catheter shaft. Manufacturing the catheter shaft may include a modified co-extrusion process that incorporates a flow valve on at least one of the material supply lines so that the supply line can be regulated by a user.

摘要： A feedblock for supplying a multi-layer stream of polymeric material to an extrusion die is provided wherein the dimension of at least some of the layers of the multi-layer stream can be precisely adjusted and/or controlled. The feedblock includes a primary flow path which is used to create a first layer and two secondary flow paths which are used to create a set of second and third layers. The secondary flow paths are positioned relative to the primary flow path such that the second and third layers are deposited on opposing sides of the primary layer in a sandwich-like configuration. Each of the secondary flow paths include a contoured slot through which a secondary fluid stream of polymeric material is deposited onto a primary stream of polymeric fluid flowing in the primary flow path. The contoured slot is geometrically shaped such that adjusting the position of the contoured slot alters the shape of the secondary fluid stream as it is deposited onto the primary flow path. A set of heaters disposed within the feedblock are positioned on either side of the combined primary and secondary flow paths adjacent to the exit port of the feedblock and are used to heat the secondary streams thereby altering the flow characteristics of the streams which, in turn, causes a corresponding change in the dimensions and profiles of the secondary fluid streams.

摘要： A flow control valve such as a melt flow control valve includes a cock plug body (2) rotatably arranged in a housing (3) having a single melt inlet port (1) extending axially relative to the rotatable cock plug body (2), and at least two melt outlet ports (4, 5) extending radially relative to the cock plug body (2). The cock plug body has a flow passage including an axially extending inflow portion (15) and at least one radially extending outflow portion (16) to selectively communicate the inlet port (1) with a selected one of the outlet ports (4, 5). The cock plug body (2) further has at least one pre-flooding passage (20) extending from the main flow channel to an opening radially displaced from the outflow portion (16), so that a pre-flooding partial flow of melt can flow from the flow channel into the next outlet port, when the cock plug body begins to be rotationally switched from one to the next outlet port.
