An injection device made up from a housing, a dose setting and injection mechanism, a dose setting member and an injection button is described. The dose setting and injection mechanism is made as a preassembled unit insertable into the housing. Both the dose setting member and the injection button is thereafter connected to the preassembled dose setting and injection mechanism inside the boundaries of the housing, while being accessible for a user from outside the housing. The same preassembled dose setting and injection mechanism can fit into a large variety of different houses making production of different variants of an injection device somewhat easier.

The method of claim 1, wherein each of said diagnostic or therapeutic devices comprises an inflatable balloon. 4. The method of claim 2, wherein the slit extends from a location not more than about 10 cm from the proximal end of the catheter body to a location at least about 10 cm proximal of the distal end of the catheter body. 5. The method of claim 2, wherein the slit extends to a location not more than about 30 cm from the proximal end of the catheter body to a location about 15 cm to about 40 cm proximal of the distal end of the catheter body. 6. A method of exchanging catheters within a patient's vascular system, comprising the steps of: a. providing a first catheter within the patient's vascular system, the first catheter comprising: i. an elongated catheter body having proximal and distal ends, ii. a guidewire-receiving inner lumen extending within the catheter body from a location not more than about 30 cm from the proximal end of the catheter body to a location at or near the distal end of the catheter body, iii. a slit in a wall of the catheter body defining at least in part the guidewire receiving inner lumen, the slit extending from a location not more than about 30 cm from the proximal end of the catheter body to a location at least about 10 cm proximal of the distal end of the ca
