Abstract

An assembly includes an introducing assembly having an elongate tubular sheath which has an external diameter. The sheath, which extends from a distal end to a proximal end, has a bore including an internal diameter sized to receive a dilator therethrough. The sheath includes a movable suture sleeve thereon. A method includes inserting an introducing assembly into a living body, and sliding a protector over a portion of the instrument and into a costoclavicular space.

Claims

1. An introducing assembly comprising:

an elongate tubular sheath having an external diameter, the sheath having a bore including an internal diameter sized to receive a dilator therethrough;

the sheath extending from a distal end to a proximal end;

a protector that includes a bore, the sheath positioned within the bore such that the sheath is slidably disposed over the external diameter of at least a portion of the elongate sheath, and

wherein the protector includes a longitudinal slot that decreases in size as the protector is compressed.

2. The introducing assembly as recited in claim 1, wherein the dilator is disposed through the sheath.

3. The introducing assembly as recited in claim 1, wherein the sheath is separable without disruption to an instrument disposed therethrough.

4. The introducing assembly as recited in claim 3, wherein the sheath includes at least one line of weakness therein.

5. The introducing assembly as recited in claim 1, wherein the protector is a flexible protector.

6. The introducing assembly as recited in claim 1, wherein the protector extends from a first end to a second end, and at least the first end is tapered.

7. The introducing assembly as recited in claim 6, wherein the second end is tapered.

8. The introducing assembly as recited in claim 1, wherein the protector includes one or more grooves thereon.

9. The introducing assembly as recited in claim 1, wherein the longitudinal slot in the protector decreases in size to reduce the outer circumference of the protector.

10. The introducing assembly as recited in claim 1, wherein the protector has a length of about ½

inch to 1 inch.

11. The introducing assembly as recited in claim 1, wherein the protector has a length of about 1 inch.

12. An introducing assembly comprising:

an elongate tubular sheath having an external diameter, the sheath having a bore including an internal diameter sized to receive a dilator therethrough;

the sheath extending from a distal end to a proximal end; and

a protector that includes a bore, the sheath positioned within the bore such that the sheath is slidably disposed over the external diameter of at least a portion of the elongate sheath, the protector having a longitudinal slot therein that decreases in size to reduce the outer circumference of the protector.

13. The introducing assembly as recited in claim 12, wherein the protector extends from a first end to a second, and the slot extends from the first end to the second end.

14. The introducing assembly as recited in claim 13, wherein the protector extends from a first end to a second end, at least one of the first and second ends having a beveled edge.

15. A method comprising:

inserting an introducing assembly into a living body, the introducing assembly including an elongate tubular sheath having an external diameter, the sheath having a bore including an internal diameter sized to receive a dilator therethrough;

the sheath extending from a distal end to a proximal end;

a protector with a longitudinal slot, the protector including a bore, the sheath positioned within the bore such that the sheath is slidably received over the external diameter of the sheath; and

the dilator removably disposed through the sheath;

inserting the sheath and dilator into a vein or artery;

removing the dilator from the sheath;

disposing an instrument through the sheath and into the vein or artery; and

sliding the protector over a portion of the instrument into the living body such that the protector is compressed by the living body and the longitudinal slot in the protector decreases in size.

16. The method as recited in claim 15, further comprising securing the protector to the living body.

17. The method as recited in claim 15, further comprising separating and removing the sheath without damage to the instrument.

18. The method as recited in claim 15, further comprising moving the protector to a position in a costoclavicular space.

19. The method as recited in claim 15, wherein sliding the protector over the instrument includes peeling and removing the sheath while pushing the protector over the instrument.

20. A method comprising:

inserting an introducing assembly into a living body, the introducing assembly including an elongate tubular sheath heaving an external diameter, the sheath having a bore including an internal diameter sized to receive a dilator therethrough;

the sheath extending from a distal end to a proximal end; and

the dilator removably disposed through the sheath;

inserting the dilator into a vein or artery of the living body;

removing the dilator from the sheath;

disposing an instrument through the sheath and into the vein or artery; and

sliding a protector that includes a bore over a portion of the instrument and into a costoclavicular space such that the costoclavicular space compresses the protector and decreases the size of a longitudinal slot in the protector.

21. The method as recited in claim 20, further comprising slidably disposing the protector over the sheath.

22. The method as recited in claim 20, further comprising slidably disposing the protector over the instrument prior to disposing the instrument through the sheath.

23. The method as recited in claim 20, further comprising securing the protector within the costoclavicular space.
