Abstract

An intravascular catheter apparatus (1) is described comprising a hub (2), means forming a first passageway (4), a canula (3), a puncturing means (9), a sealing means (8) and a means forming a second passageway (5) with said sealing means (8) extending a predetermined distance into said second passageway (5) for closing a hole (17) left in said sealing means (8) upon the withdrawal of said puncturing means (9) therefrom in response to a contact with a member (15) inserted in the second passageway (5).

Claims

1. A catheter comprising:

a hub;

means forming a first passageway in said hub;

a canula extending from said hub and communicating with said first passageway;

a puncturing means for inserting said canula in a body;

a sealing means in the first passageway for removably receiving said puncturing means, said sealing means including a solid member of resilient material and being of a size to permit the puncturing means to pierce and to extend through the solid member; and

means forming a second passageway in said hub adjacent to and communicating with said first passageway with said solid member partially extending into the second passageway and being located in a position to be contacted and compressed by a connector member inserted in said second passageway for compressing said sealing means to close a hole formed therethrough by said puncturing means after the withdrawal of said puncturing means from said solid member.

2. A catheter according to claim 1 wherein said first and said second passageways are generally cylindrically shaped and open to each other along substantially all of one side thereof for permitting the fabrication thereof using injection molding technique without a slide.

3. A catheter according to claim 1 wherein said first and said second passageways are generally cylindrically shaped, the axes of said first passageway and said canula are colinear, the axis of said second passageway is parallel to the axis of said first passageway;

and said first and said second passageways are in fluid communication with each other.

4. A catheter comprising:

a hub having a pair of side-by-side passageways;

a canula coupled to the hub and extending outwardly therefrom in fluid communication with said passageways;

a solid, resilient sealing member in a first of the passageways, said sealing member being of a size to permit a puncturing means to pierce and extend through the member when the puncturing means extends through the first passageway and the canula, said sealing member extending partially into the second passageway and being engageable by a connector member inserted into the second passageway to cause the sealing member to be compressed and to close a hole formed by the puncturing means extending through the sealing member after removal of the puncturing means therefrom.

5. A catheter as set forth in claim 4, wherein the first and second passageways have a common side boundary.

6. A catheter as set forth in claim 4, wherein the passageways are generally cylindrical, said sealing means comprising a generally cylindrical plug extending into the first passageway and having an outer peripheral portion extending into the second passageway.
