Abstract

In order to destroy vascular deformations in the human body, a clamp is provided which is made from titanium. The clamp is expanded in the relieved state and is transferable into the clamping position by a clamping ring, which is displaceable along the clamp in the attached state. The clamp is introduced into the body by a probe, which has a tubular casing and a positioning bar guided therein. The clamp is transferred into the region of the deformation and applied at the application location as a result of the clamping ring being transferred into the clamping position. The transfer is caused by a relative movement between tubular casing and positioning bar. The probe is then released from the positioned clamp.

Claims

1. Apparatus for treating vascular deformations, comprising:

a clamp for closing a deformation;

expanded arms on said clamp for attaching said clamp to said deformation, said clamp being formed of material compatible with the deformation;

a positioning tool with a handle and an adjusting member;

a tubular probe displaceable in said handle in an axial direction by said adjusting member;

a positioning bar mounted in said handle and extending through said tubular probe and terminating in a gripper attachable to said clamp;

said gripper having claws expandable out of engagement with said tubular probe when placed outside said tubular probe and displaced towards one another when said tubular probe is advanced and surrounds the claws for being enclosed by said tubular probe and being effective on said clamp;

said clamp being of titanium, said arms being formed by two semicircular profiled bars expanded when in a relieved state;

a base with corners on a periphery protruding laterally from the clamp, said semicircular profiled bars conveying together at a bottom end of said base, said semicircular profiled bars having a curved portion;

a clamping ring enclosing said bars and being displaceable in a longitudinal direction of said clamp through said curved portion of said bars;

said positioning bar being secured relative to said handle in an axial direction and extending through said tubular probe, said tubular probe being displaceable in said handle in an axial direction relative to said handle and being resistant to bending, said claws surrounding only said base and said corners of said base, said base limiting movement of said clamping ring in a backward direction, said claws engaging said base with the corners protruding from the clamp to hold the clamp during advancement of said tubular probe.

2. Apparatus as defined in claim 1, wherein said handle comprises a pistol body having a grip, said adjusting member for said tubular probe comprising a trigger guard.

3. Apparatus as defined in claim 2, wherein said tubular probe has an annular shoulder enclosed by a bifurcated end of said trigger guard.

4. Apparatus as defined in claim 1, wherein said tubular probe and said positioning bar are jointly securably mounted relative to said handle for being rotatable about a longitudinal axis of said probe.

5. Apparatus as defined in claim 1, wherein said handle has a securable hand grip displaceable in said longitudinal direction relative to bearing shells enclosing said tubular probe;

and fastening means for bringing together said bearing shells.

6. Apparatus for treating vascular deformations, comprising:

a clamp for closing a deformation;

expanded arms on said clamp for attaching said clamp to said deformation, said clamp being formed of material compatible with the deformation;

a positioning tool with a handle and an adjusting member;

a tubular probe displaceable in said handle in an axial direction by said adjusting member;

a positioning bar mounted in said handle and extending through said tubular probe and terminating in a gripper attachable to said clamp;

said gripper having claws expandable out of engagement with said tubular probe when placed outside said tubular probe and displaced towards one another when said tubular probe is advanced and surrounds the claws for being enclosed by said tubular probe and being effective on said clamp;

said clamp being of titanium, said arms being formed by two semicircular profiled bars expanded when in a relieved state;

a base with corners on a periphery protruding from the clamp, said semicircular profiled bars conveying together at a bottom end of said base, said semicircular profiled bars having a curved portion;

a clamping ring enclosing said bars and being displaceable in a longitudinal direction of said clamp through said curved portion of said bars;

said positioning bar being secured relative to said handle in an axial direction and extending through said tubular probe, said tubular probe being displaceable in said handle in an axial direction relative to said handle and being resistant to bending, said tubular probe having an end face with receiving means;

a mandrel for traversing said clamping ring and received in said receiving means;

said mandrel protruding at two ends beyond said semicircular profiled bars;

said receiving means comprising a bayonet-type securing means;

said tube being mounted in said handle for being rotatable about a longitudinal axis of said tube.

7. Apparatus as defined in claim 6, wherein said handle has a recess exposing said tubular probe, said adjusting member being associated with said tubular probe in a region of said recess for rotating said tubular probe relative to said positioning bar.

8. Apparatus as defined in claim 7, wherein said adjusting member comprises a knurled ring associated with said tubular probe.

9. Apparatus for treating vascular deformations, comprising:

a clamp for closing a deformation;

expanded arms on said clamp for attaching said clamp to said deformation, said clamp being formed of material compatible with the deformation;

a positioning tool with a handle and an adjusting member;

a tubular probe displaceable in said handle in an axial direction by said adjusting member;

a positioning bar mounted in said handle and extending through said tubular probe and terminating in a gripper attachable to said clamp;
