Abstract

Abstract The invention relates to a device for placing styptic material, in particular of fibrous or spongy form, on perforated blood vessels, in particular arteries. A tube arrangement is provided which consists at least of a plug holder (2) and a thin-walled sheath (1) connected therewith which serves to guide the styptic material onto a perforation of a blood vessel. The device also comprises a pusher (3) which is arranged to be longitudinally displaceable in the tube arrangement, and a tissue dilator (10) guided in the tube arrangement essentially free of play, the tissue dilator having an outer diameter greater than that of the perforation and a coaxial guide channel (11).

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 103 words
Device for placing styptic material, in particular of a fibrous or spongelike form, onto perforated blood vessels, in particular arteries, characterized by - a tube arrangement consisting at least of a plug holder (2) and a thin-walled sheath (1) connected therewith for guiding the styptic material to a perforation in a blood vessel, - a pusher (3) insertable into the tube arrangement to be displaceable in the longitudinal direction, and - a tissue dilator (10) guidable in the tube arrangement essentially without play, the tissue dilator (10) having an outer diameter greater than that of the perforation, and a coaxial guiding channel (11).
Claim 2
Dependent Claim 103 words
Device for placing styptic material, in particular of a fibrous or spongelike form, onto perforated blood vessels, in particular arteries, characterized by - a tube arrangement consisting at least of a plug holder (2) and a thin-walled sheath (1) connected therewith for guiding the styptic material to a perforation in a blood vessel, - a pusher (3) insertable into the tube arrangement to be displaceable in the longitudinal direction, and - a tissue dilator (10) guidable in the tube arrangement essentially without play, the tissue dilator (10) having an outer diameter greater than that of the perforation, and a coaxial guiding channel (11).
Claim 3
Dependent Claim 27 words
Device according to claim 1, characterized in that the plug holder (2) and the sheath (1) have an essentially similar inner diameter constant over their entire length.
Claim 4
Dependent Claim 23 words
Device according to claim 1 and 2, characterized in that the sheath (1) and the plug holder (2) are arranged coaxially in series.
Claim 5
Dependent Claim 31 words
Device according to claim 1 and 2, characterized in that the plug holder (2) is connected to the sheath (1) at an acute angle of approximately 5 to 45 ° .
Claim 6
Dependent Claim 45 words
Device according to claim 1, characterized in that the tube arrangement has a tube (13) serving as a thin-walled sheath and as a plug holder (2), a guide tube (12) for the tissue dilator (10) being connected to the tube (13) at an acute angle.
Claim 7
Dependent Claim 32 words
Device according to one of the preceding claims, characterized in that the sheath (1) is connected to the plug holder (2) by means of a screw fitting (4) or a plug connection.
Claim 8
Dependent Claim 21 words
