Claims (8)
- 유연성을 가진 코일 본체와, 그 코일 본체에서의 내주면 및 외주면의 한쪽 또는 양쪽에 마련된, 흡수(吸水)하여 팽윤함에 의해 그 코일 본체의 신장을 억제하는, 수팽윤성(水膨潤性)을 가진 고분자 재료로 되는 신장 억제 부재로 되는 것을 특징으로 하는 색전 형성용 체내 유치 코일.
- 제1항에 있어서, 신장 억제 부재를 구성하는 수팽윤성을 가진 고분자 재료가 폴리비닐알콜계의 중합체로 구성되어 있는 색전 형성용 체내 유치 코일.
- 제1항 또는 제2항에 있어서, 코일 본체를 구성하는 선재(線材)의 직경이 10∼120㎛, 코일 본체의 코일 지름이 100∼500㎛, 코일길이가 2∼500mm, 단위 길이(1mm)당 권횟수가 1∼100인 색전 형성용 체내 유치 코일.
- 제1항 또는 제2항에 있어서, 로드(rod)상(狀) 또는 통상(筒狀)의 신장 억제 부재가 코일 본체의 코일 축방향으로 뻗도록 그 코일 본체의 내부에 삽입되어 마련되어 있는 색전 형성용 체내 유치 코일.
- 제4항에 있어서, 신장 억제 부재의 직경은 건조 상태에서 코일 본체의 코일 내경에 대해서 1∼50% 정도 작은 것인 색전 형성용 체내 유치 코일.
- 제1항 또는 제2항에 있어서, 원통상 또는 튜브상으로 형성되는 신장 억제 부재가 코일 본체의 외주면을, 코일 축방향의 전역에 걸쳐서 피복하는 상태로 마련되어 있는 색전 형성용 체내 유치 코일.
- 제6항에 있어서, 건조 상태에서, 신장 억제 부재의 두께는 0.01∼0.10mm, 코일 본체의 외주면과 신장 억제 부재의 내주면 사이의 클리어런스는 0∼100㎛인 색전 형성용 체내 유치 코일.
- 제1항 또는 제2항에 있어서, 로드상 또는 통상의 신장 억제 부재가 코일 본체의 코일 축방향으로 뻗도록 그 코일 본체의 내부에 삽입되어 마련되어 있는 동시에, 원통상 또는 튜브상으로 형성되는 신장 억제 부재가 코일 본체의 외주면을, 코일 축방향의 전역에 걸쳐서 피복하는 상태로 마련되어 있는 색전 형성용 체내 유치 코일.
