项目摘要

Project Summary The overall goal of this SBIR proposal is to develop a novel vaginal stent for use in pediatric and adult populations. There are many girls and women born with congenital gynecologic abnormalities requiring surgical reconstruction of their vaginal cavities. There are also women who have very shortened or scarred vaginas after pelvic surgery or radiation treatment for cancer. Vaginal stents can be used after neo-vagina creation to prevent scarring and re-stenosis. There are no currently available vaginal stents that meet the anatomic needs of pediatric and adolescent girls or women who are post treatment for gynecologic cancers. As such, there is a high rate of post-surgical complications such as vaginal tissue scaring and vaginal stenosis. We propose to create new vaginal stents with improved fit, ease of use, unique deployment and retrieval mechanisms, and enhanced comfort for a pediatric population and for those women with shortened vaginas. BioTex has entered into an option agreement with collaborating physicians at Texas Children’s Hospital (Baylor College of Medicine) to create the newly designed stent based on pending patents filed by our clinical collaborators. The objectives of our Phase I proposal is to build fully functional prototypes, conduct benchtop testing, and perform in vivo studies in porcine vaginal tracts to demonstrate performance of the stents. We believe this new vaginal stent will reduce post-surgical morbidity, early discontinuation of stent use postoperatively, reduce health care costs, and improve clinical outcomes for girls and women across North America.

项目摘要该SBIR提案的总体目标是开发一种新型的阴道支架，用于小儿和成人人群。有许多女孩和妇女出生的先天性妇科异常需要其阴道咖啡馆的手术重建。还有一些妇女缩短或疤痕骨盆手术或癌症辐射治疗后的阴道。在新维吉纳（Neo-Vagina）之后可以使用阴道支架创建以防止疤痕和重新发生。当前没有可用的阴道支架可以符合小儿和青少年女孩或妇科癌症治疗后的儿童和青少年的解剖需求。作为这样的术后并发症发生率很高，例如阴道组织恐惧和阴道狭窄。我们建议以提高适合度，易用性，独特的部署和检索来创建新的阴道支架机制，以及对小儿人群以及那些阴道缩短的妇女的舒适感。 Biotex已与德克萨斯儿童医院的合作医生签订了期权协议（贝勒医学院），根据我们的临床提交的未决专利，创建新设计的支架合作者。我们阶段提案的目标是建立功能齐全的原型，进行台式测试并在猪阴道束中进行体内研究，以证明支架的性能。我们相信这种新的阴道支架将降低手术后发病率，早期停移使用术后，降低医疗保健成本，改善北部的女孩和妇女的临床结果美国。
