연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A connector connects a silicone or other radially expandable catheter to a catheter that does not expand radially. The catheter includes a hollow first connection part, a hollow second connecting part and a locking sleeve. The hollow second connecting part is threadably connected to the first connection part. The second part has a rib protruding from an external surface thereof. The rib has a recessed notch. A locking sleeve has a lip projecting radially inwardly therefrom at each end. The lip at the second end is fixedly received within the recessed notch. The lip at the first end is disposed about the external surface of the connection part. The locking sleeve is axially movable with respect to the first connection part. Axial movement of the locking sleeve in one direction is limited, thereby preventing disassembly of the first connecting part and the second connecting part.

The connector assembly according to claim 1, wherein said collet has an external beveled surface that mates with the beveled second shoulder of said first connection part.3. The connector assembly according to claim 1, wherein said spacer is disposed between said collet and said at least one o-ring.4. The connector assembly according to claim 1, wherein said externally projecting annular rib of said first connecting part is disposed at a predetermined distance from said second end.5. The connector assembly according to claim 1, wherein said internal surface of said first connection part further includes a third shoulder transitioning to a fourth further reduced diameter bore.6. The connector assembly according to claim 1, wherein a radial inner portion of said second shoulder of said first connection part includes said beveled portion.7. The connector assembly according to claim 6, wherein said collet has an external beveled surface that mates with the beveled second shoulder portion of said first connection part.8. The connector assembly according to claim 1, wherein said kink proof catheter includes a wire coil connected to an internal surface thereof.9. The connector assembly according to claim 8, wherein said wire is made of titanium.10. The connector assembly according to claim 9, wherein said wire has a diameter of about 0.005 inches.11. The connector assembly according to claim 1, wherein said collet includes a plurality of slots.12. The connector assembly according to claim 1, wherein said silicone catheter is disposed about said barb.13. A connector comprising:a hollow first connection part having a first end and a second end, said first end having a barb protruding from an external surface thereof for connecting to a silicon tube, said second end having an internal threaded surface, and an externally projecting annular rib, said internal surface extending from said second end to said first end with said internal threaded surface, a first bore, a first shoulder transitioning to a second reduced diameter bore, a second shoulder transitioning to a third further reduced diameter bore, said second shoulder having at least a portion thereof being beveled; a hollow second connecting part being threadably connected to said first connection part, said second connecting part having a first end and a second end, said first end having an external threaded surface that mates with the internal threaded surface of said first connection part, said second part having a rib protruding from an external surface thereof, said rib having a recessed notch; a locking sleeve having a first end and a second end, each of said ends having a lip projecting radially inwardly therefrom, said lip at said second end being fixedly received within said recessed notch, said lip at said first end being disposed about said external surface of said first connection part on a side of said externally projecting annular rib of said first connection part remote from said second end of said first connection part, said locking sleeve being axially movable with respect to said first connection part, said axial movement in one direction being limited by abutment of said externally projecting annular rib of said first connection part and said inwardly projecting lip on said first end of said locking sleeve, thereby preventing disassembly of said first connecting part and said second connecting part; a collet being disposed within said second bore of said first connection part for selectively fixedly engaging with the outer surface of a kink proof catheter; at least one o-ring being disposed within said first bore of said first connection part for selectively sealingly engaging with the outer surface of a kink proof catheter; and a spacer being disposed within said first bore of said first connection part. 14.
