Abstract
Abstract The invention relates to a procedure as well as a device for introducing an endoprosthesis into the distal end of a catheter by means of which the endoprosthesis is introduced into a vessel for implantation therein and is released to undergo self expansion by moving the tip of a catheter axially relative to the distal end of an outer catheter. An embodiment of the proposed device comprises a hollow cylindrical housing designed to receive the endoprosthesis, a piston axially displaceable therein which can be brought into engagement with the endoprosthesis, and a nose section arranged at one end of the housing, said nose section being provided with a recess tapering in the direction of an opening, and by means of said recess the endoprosthesis supplied by the piston may be introduced, with compressed diameter and in elongated form, into the distal end of the catheter replaceably arranged on the nose section.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
58 words
A device for introducing a tubular, self-expanding endoprosthesis into a catheter shaft, the device comprising: a housing for receiving the endoprosthesis; a piston unit having an axis coaxially aligned with an axis of the catheter shaft for axially displacing the endoprosthesis relative to the shaft; and a tapering outlet opening in the housing for radially compressing the endoprosthesis.
Claim 2
Independent Claim
58 words
A device for introducing a tubular, self-expanding endoprosthesis into a catheter shaft, the device comprising: a housing for receiving the endoprosthesis; a piston unit having an axis coaxially aligned with an axis of the catheter shaft for axially displacing the endoprosthesis relative to the shaft; and a tapering outlet opening in the housing for radially compressing the endoprosthesis.
Claim 3
Dependent Claim
42 words
The device of claim 1 wherein the housing further comprises a hollow cylinder having an axis, said piston unit within the cylinder and displaceable along the axis of the cylinder, and an outlet opening arranged coaxially to the axis of the cylinder.
Claim 4
Dependent Claim
16 words
The device of claim 1 wherein the outlet opening has the form of a truncated cone.
Claim 5
Dependent Claim
13 words
The device of claim 3 wherein the truncated cone possesses an oblique angle.
Claim 6
Dependent Claim
19 words
The device of claim 1 wherein the outlet opening has the form of a series of adjacent truncated cones.
Claim 7
Dependent Claim
16 words
The device of claim 1 wherein the outlet opening has the form of a hyperboloidal section.
Claim 8
Dependent Claim
19 words
The device of claim 1 wherein the outlet opening is arranged in a replaceable nose section of the housing.
Claim 9
Dependent Claim
23 words
The device of claim 7 wherein the nose section of the housing is replaceable by virtue of being provided with a threaded connection.
Claim 10
Dependent Claim
11 words
The device of claim 7 wherein the nose section is divisible.
Claim 11
Dependent Claim
30 words
The device of claim 9 wherein the nose section possesses two parts connected by a joint, said parts being pivotable between an open, replacement position and a closed, locking position.
Claim 12
Dependent Claim
20 words
The device of claim 10 wherein the parts are lockable in the closed position to fasten them on the housing.
Claim 13
Dependent Claim
18 words
The device of claim 1 wherein the piston unit is annular in shape and has an axial recess.
Claim 14
Dependent Claim
27 words
The device of claim 1 wherein the housing possesses a connecting opening, arranged coaxially to the outlet opening, for receiving an end section of the catheter shaft.
Claim 15
Dependent Claim
15 words
The device of claim 13 wherein the outlet opening possesses several sections with stepped diameters.
Claim 16
Dependent Claim
16 words
The device of claim 1 wherein the housing is made at least partially of transparent material.
Claim 17
Dependent Claim
27 words
The device of claim 1 wherein the housing may be opened laterally in relation to the direction of movement of the piston unit to receive the endoprosthesis.
Claim 18
Dependent Claim
21 words
The device of claim 1 wherein the piston unit may be removed from the housing in order to receive the endoprosthesis.
