| 摘要 | A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison. | ||

| 主权项 | 1. A medical balloon formed by radial expansion of an assembled tubular parison, the balloon comprising a body, waist and cone portions, the assembled tubular parison comprising: a first tube of orientable polymer material, a second tube formed of orientable polymer material disposed around the first tube, the first tube, or the second tube, or both, having been longitudinally pre-stretched after formation thereof but before assembly of the parison, and an adhesive layer disposed between the first and second tubes and contacting the first and second tubes. | ||
