摘要： In at least one embodiment of the present invention, an introducer for use in inserting a medical device into a body vessel of a patient is provided. The introducer comprises a housing having a proximal opening, a distal opening and a chamber extending therebetween. A seal in diaphragm form is disposed in the chamber. The seal is formed of polymeric material having a first phase transition temperature higher than about body temperature and a second phase transition temperature that is less than the first phase transition temperature but is greater than about room temperature. The seal is in a first configuration and has an opening formed therethrough when at about room temperature for advancing the medical device through the seal. The seal self-configures to a second configuration when at a temperature of at least the second phase transition temperature for obstructing the body fluid from flowing through the opening of the seal.

摘要： In at least one embodiment of the present invention, a drainage catheter for draining part of patient's body is provided. The catheter comprises an elongated member having a proximal portion extending to a distal portion and a lumen formed therethrough for fluid communication with the patient's body. The distal portion is formed of a polymer material having a first phase transition temperature and a second phase transition temperature that is less than the first phase transition temperature but is greater than about body temperature. The distal portion has a first configuration when at about body temperature for at least one of moving and anchoring the distal portion within the patient's body. The distal portion self-configures to a second configuration when at a temperature of at least the second phase transition temperature for retrieval of the distal portion from the patient's body.
摘要翻译：在本发明的至少一个实施例中，提供了用于排出患者身体的部分的引流导管。导管包括细长构件，其具有延伸到远端部分的近端部分和穿过其形成的内腔，用于与患者身体流体连通。远侧部分由具有第一相转变温度和小于第一相变温度但大于约体温的第二相变温度的聚合物材料形成。当在大约体温时，远侧部分具有第一构造，用于将远端部分移动并锚定在患者身体内的至少一个。当处于至少第二相转变温度的温度下，远端部分自身构造成第二构型，用于从患者身体取回远侧部分。
