Medical Component Insertion Device Including a Retractable Needle |
摘要 |
An insertion device for use in assisting with the placement of a medical device within the body of a patient is disclosed. For example, the insertion device can be employed to assist with the placement of an introducer, which provides a conduit for insertion of a catheter into the body. In one embodiment, the insertion device comprises a needle that is removably disposed within a bore defined by the medical device, and a needle retraction assembly. The needle retraction assembly can position the needle in any one of a first position wherein a distal tip of the needle is disposed a predetermined distance distal to a distal end of the medical device, a second position wherein the needle distal tip is disposed distal but proximate to the distal end of the medical device, and a third position wherein the needle distal tip is retracted within the medical device bore.
