摘要： A medical balloon and a catheter utilizing the balloon and a mechanism to attach the medical balloon to the catheter tube, and method of making the balloon. The attachement mechanism forms a joint and comprises a plurality of co-extruded and coextensive layers of different polymeric materials, at least one of which is a base structural layer and the other of which is formed of polyethylene and copolymers thereof or of Selar. The base structural layer is thicker then the other layer. The attachment mechanism can be the balloon itself or it can be a sleeve, either of which is heat sealed to the catheter tube. In either case, the diameter of the catheter at the joint is substantially the same as the tube.
摘要翻译：使用气囊的医疗气囊和导管以及将医用气囊附接到导管的机构以及制造气囊的方法。附着机构形成接头并且包括多个不同聚合材料的共挤出和共同延伸的层，其中至少一个是基础结构层，另一个由聚乙烯及其共聚物或Selar形成。底层结构层比另一层厚。附接机构可以是球囊本身，也可以是套筒，其中任一个被热密封到导管管上。在任一情况下，接头处的导管的直径与管基本相同。

摘要： A method of forming a balloon for medical purposes including co-extruding in a tubular shape a base structural layer of polyamides, polycarbonates, polyesters and copolymers thereof and a heat sealable layer of polyethylene and copolymers thereof. The tubular member is then biaxially oriented by inflating the tube with a gas to a predetermined central diameter greater then the initial diameter of the tube and simultaneously heating the inflated tube to a temperature sufficient to biaxially orient the base structural layer. The member is then cooled the inflated tubular member and then elevated in temperature for a second time to the biaxially orienting temperature. The twice-heated tube is allowed to cool and the gas is withdrawn whereby the tubular member will assume a generally tubular shape and the main structural layer will remain biaxially orientated and the heat sealable layer will not be biaxially orientated.
摘要翻译：一种形成用于医疗目的的球囊的方法，包括以管状共挤出聚酰胺，聚碳酸酯，聚酯及其共聚物的基础结构层，以及可热封的聚乙烯层及其共聚物。然后通过将管子充气至预定的中心直径大于管的初始直径并同时将膨胀的管加热到足以使基部结构层双轴取向的温度，将管状构件双轴取向。然后将构件冷却膨胀的管状构件，然后将温度升高第二次以达到双轴取向温度。允许两次加热的管冷却并且气体被排出，由此管状构件将呈现大致管状形状，并且主结构层将保持双轴取向并且可热封层将不会双轴取向。

摘要： A sleeve for attaching a medical balloon to a catheter utilizing a balloon (8). The sleeve comprises a plurality of co-extruded and coextensive layers of different polymeric materials (20A, 20B) at least one of which is a base structural layer (20B) and the other of which (20A) is formed of polyethylene and copolymers thereof or of Selar. The base structural layer is thicker than the other layer. The diameter of the catheter at the joint (10, 11) is substantially the same as the tube.
