Abstract
Tool and method for turning or steering an angioplasty guide wire as it is inserted into the body of a patient. The tool has a body of resilient material with a slit in which the guide wire is received. The slit opens through the side of the body, and the tool can be attached to the wire from the side. An outer sleeve encircles the resilient body, with a slot through which the wire is inserted and removed, and the resilient body is compressed by the sleeve to hold the slit closed and grip the wire tightly. The wire is turned or steered by gripping the outer sleeve and rotating the tool about its axis.
Claims8
In a tool for turning an angioplasty guide wire to steer the wire as it is inserted into a patient:
- a body of resilient material having a longitudinally extending slit opening laterally through one side thereof for receiving and gripping the wire, and a relatively rigid sleeve encircling body and compressing the resilient material to hold the slit closed tightly about the wire, said sleeve having a longitudinally extending slit through which the wire can pass and an outer surface adapted to be gripped by a person using the tool to rotate the guide wire.
In a tool for turning an angioplasty guide wire to steer the wire as it is inserted into a patient:
- an axially elongated generally cylindrical body of resilient material having a radial slit through one side thereof for receiving and gripping the guide wire, and a relatively rigid outer sleeve which compresses the resilient body and holds the slit closed tightly, said sleeve being adapted to be gripped by a person using the tool to rotate the guide wire, said sleeve having a longitudinally extending slot aligned with the slit in the resilient body through which the guide wire can pass as the tool is attached to the guide wire from the side.
In a method of steering an angioplasty guide wire with a tool having a body of resilient material with a longitudinally extending slit opening through one side thereof and a relatively rigid sleeve encircling the resilient body and compressing the resilient material to hold the slid closed, the steps of:
- attaching the tool to the guide wire by pressing the wire into the closed slit so that the wire is gripped and held securely by the resilient material, and turning the sleeve to turn the guide wire.
