A method of forming an implant in the tissue can include: providing an injectable composition having a neat liquid carrier, wherein the neat liquid carrier is substantially liquid at room temperature and/or about body temperature; and injecting the neat liquid solution into the tissue at the rate of 10-12000 injections per minute and/or at an amount of 1.0E-02 ml to 1.0E-16 ml per needle per injection. The neat liquid carrier can be polymeric or non-polymeric. The neat liquid carrier can be biodegradable. The neat liquid carrier can include a viscosity-modifying agent. The injecting can form an implant with area greater than or equal to 5 mm2. The neat liquid carrier can be injected at a depth of 10 microns to 5 mm. The neat liquid solution can include a drug or other agent.
在组织中形成植入物的方法可以包括:提供具有纯液体载体的可注射组合物,其中纯液体载体在室温和/或大约体温下基本上是液体;以每分钟 10-12000 次注射的速度和/或每针每次注射 1.0E-02 ml 至 1.0E-16 ml 的量将纯液体溶液注射到组织中。纯液体载体可以是聚合物或非聚合物。纯液体载体可以是可
生物降解的。纯液体载体可以包括粘度调节剂。注射可形成面积大于或等于 5 平方毫米的植入物。纯液体载体的注射深度为 10 微米至 5 毫米。纯液体溶液可包括药物或其他制剂。
