DRUG DELIVERY AND CATHETER SYSTEMS, APPARATUS AND PROCESSES |
摘要 |
A class of customizable injection devices or delivery instrumentswhose basic form is a stiff tube with holes of user-selectable size at several user-selectable places is described. The use of this device includes a method of selection and construction of a particular device from such a class of devices for a particular treatment procedure using computer-assisted means. Thus, the user may make selections among available or creatable choices (such as selection of hole size, hole location, number of holes, etc.), and a method can be practiced for making such user-selection serve the goals of delivery of materials such as drugs, cells, or of devices sufficiently small and numerous to be delivered in fluid suspension. The tube should be relatively stiff in the sense that it deflects by no more than an amount between 0 DEG and 15 DEG under the stresses of insertion and placement at the end of a catheter.
