Methods and devices relating to surgical guidewire devices

A guidewire device adapted to be secured to and released from a guidewire, the device comprising:

• a first body having a substantially half-cylindrical shape and defining a first groove extending laterally therein, the first groove being padded to form a first padded half-cylindrical groove, wherein the first groove is on an inner surface of the first body and has a substantially half-cylindrical shape extending laterally in the first body;
• a second body having a substantially half-cylindrical shape and defining a second groove extending laterally therein, the second groove being padded to form a second padded half-cylindrical groove;
• a friction coupling that mechanically couples the first body to the second body, the friction coupling including:
• a protrusion located on a first edge of the first body facing a complementary second edge of the second body;
• a receiving end on the second edge comprising a tensioned pin and spring system, the receiving end being positioned across from the protrusion and shaped to receive the protrusion into a locking arrangement;
• a button located on a first side face of the first body, comprising a rod that extends through the first body on an axis that is parallel to the tensioned pin and spring system of the receiving end and may be coupled with the tensioned pin and spring system such that when the button is compressed, the tensioned pin and spring system releases the protrusion from the receiving end;
• wherein the first body is coupled, by a hinge, to the second body latitudinally around a rotational axis that is parallel to the guidewire's axis, such that the first body and the second body are configured to rotate around the rotational axis with respect to each other from an open configuration to a closed configuration, wherein the first body and the second body are configured to be brought and held into contact with one another by the friction coupling when rotated into the closed configuration so as to lock together and remain in place relative to the guidewire when in the closed configuration;
• and
• wherein the first body and second body, when rotated into the closed configuration, are configured to come into contact with one another and be fixed together relative to the guidewire via locking engagement of the protrusion with the receiving end and the tensioned pin and spring system, wherein, when locked together in the closed configuration, the first padded half-cylindrical groove and the second padded half-cylindrical groove form a general circle around an outer surface of the guidewire, so as to contact the guidewire and securely hold the guidewire within the guidewire device and enable a user to apply torque when the device is in the closed configuration and the notched end is coupled to the tensioned pin and spring system.

A guidewire device comprising:

• a substantially circular body having a first body hingedly coupled to a second body, wherein in a closed position a first surface of the first body directly contacts a first surface of the second body and in an open position the first surface of the first body is spaced apart from the first surface of the second body;
• wherein a first plate is fixed to the first body and wherein a second plate is fixed to the second body;
• and
• a clip comprised of a set of wings integrally coupled together by a bridge portion to form a substantially triangularly-shaped spring clamp that biases end portions of the set of wings towards each other into a closed position;
• wherein the set of wings is coupled to an inner surface of the first body and the second body having first ends that engage the first and second plates, respectively, and a set of jaws held together by the substantially triangularly-shaped spring clamp;
• wherein the clip is disposed, in entirety, radially within the substantially circular body, wherein the set of jaws of the clip are configured to compress the first and second plates around a guidewire and thereby frictionally secure the guidewire device in place on the guidewire as a result of compressive force of the substantially triangularly-shaped spring clamp;
• wherein the guidewire device is configured to hold the guidewire in position between either:
• (1) an inner surface of the first plate at a distal end of the first plate abutting the bridge portion of the clip, an inner surface of the second plate at a distal end of the second plate, and the bridge portion of the substantially triangularly-shaped spring clamp of the clip;
• or
• (2) opposing inner surfaces of the first plate and the second plate.
