## Abstract

A compression torque device comprises a housing, an actuator, a flexible clamping member and a linear lumen. The housing comprises a body, a handle, a leading portion and an actuator opening. The actuator is operably coupled to the housing at the actuator opening. The linear lumen passes through the housing and is contiguous with the actuator opening. The actuator pivots between a first position and a second position, such that the flexible clamping member extends into the lumen when the actuator is in the first position and does not extend into the lumen when the actuator is in the second position. The actuator and the flexible clamping member may be monolithic. A kit for catheter-based intervention comprises a compression torque device and an adaptor.

## Claims

### Claim 1

A compression torque device, consisting of:
a housing, comprising
a body,
a handle,
a leading portion, and
an actuator opening, in the body,
a first opening on the leading portion,
a second opening on the handle,
an actuator, operably coupled to the housing at the actuator opening,
a flexible clamping member,
optionally, an introducer, coupled to the housing, and
a linear lumen, passing through the housing and contiguous with the actuator opening,
wherein the actuator and the flexible clamping member are monolithic and formed of the same material,
the housing is monolithic, and
the actuator pivots between a first position and a second position about a hinge point between ends of the actuator, such that the flexible clamping member extends further into the lumen when the actuator is in the first position and extends less into the lumen when the actuator is in the second position.

### Claim 2 (depends on 1)

The compression torque device of claim 1, wherein the lumen is tapered.

### Claim 3 (depends on 1)

The compression torque device of claim 1, wherein the housing comprises a latch and the actuator comprises a tab,
wherein the tab passes under the latch when the actuator is in the first position, and
the latch prevents unintentional movement of the actuator when the actuator is in the first position, wherein the leading portion of the hosing comprises a fitting.

### Claim 4 (depends on 1)

The compression torque device of claim 1, wherein the compression torque device does not comprise metal.

### Claim 5 (depends on 1)

The compression torque device of claim 1, produced by injection molding.

### Claim 6 (depends on 1)

A kit for catheter-based intervention, comprising:
the compression torque device of claim 1,
optionally, an introducer, and
an adaptor.

### Claim 7 (depends on 1)

The compression torque device of claim 1, wherein the housing is monolithic,
the handle is textured,
the leading portion of the housing comprises a Luer fitting, and
the housing comprises a latch and the actuator comprises a tab,
wherein the tab passes under the latch when the actuator is in the first position, and
the latch prevents unintentional movement of the actuator when the actuator is in the first position.

### Claim 8 (depends on 1)

The compression torque device of claim 1, wherein the introducer is removably coupled to the housing.

### Claim 9 (depends on 1)

The compression torque device of claim 1, wherein the introducer and the housing are monolithic.

### Claim 10 (depends on 1)

The compression torque device of claim 1, wherein the introducer is radiopaque.

### Claim 11 (depends on 1)

The compression torque device of claim 1, wherein the handle is textured.

### Claim 12 (depends on 1)

The compression torque device of claim 1, wherein the handle comprises finger grips.

### Claim 13 (depends on 6)

The kit of claim 6, wherein the compression torque device and the adaptor are sterile.
