摘要： The invention relates to a catheter introducer comprising: a tube-like introducer sheath; an introducer hub having a distal section and a proximal section, wherein the distal section is joined to the proximal end of the introducer sheath and the proximal section defines a chamber; a needle extending through the introducer hub and the introducer sheath and having opposite proximal and distal ends, the distal end forming a needle tip; a needle hub attached to the proximal end of the needle; a needle safety device slidably arranged on the needle, wherein the needle safety device is retained in the chamber of the introducer hub when the needle extends through the introducer hub and the introducer sheath, and removable from the introducer hub once the needle tip is received in the needle safety device upon withdrawal of the needle from the introducer sheath.

摘要： A catheter (2) is used in medical applications, for example for the retrieval of a sample from a patient or the insertion or retrieval of medical devices such as filters, stents (3) to and from the patient. The catheter (2) includes an expandable tip (6) at a leading portion of a catheter tube portion (5). This expandable tip (6) can retrieve or deliver samples, medical devices, etc. (3), which are slightly larger than the dimensions of a main catheter tube (5) inserted into the patient. The expandable tip (6) can also include extension members (10) which provide axial support to the expandable tip (6) but which still allow expansion in the radial direction.
