Abstract
A torque device can provide more control of the guidewire with less user effort. The torque device may include a first member, a second member, and a connecting member that couples the first member and the second member; and a locking member slidably coupled to the first member and/or the second member. The locking member may be configured to move along at least a portion of a side of the first member and the second member between one or more positions corresponding to operation states. The operation states may include a closed state in which the side of the first member and of the second member are fixedly secured with respect to the locking member, and one or more open states in which at least a portion of the side of first member and at least a portion of the side of the second member are separated.
Core Innovation
The invention relates to a guide-wire torque device that provides a body including a first end, a second end, and a length therebetween, and that includes a first member, a second member, and a connecting member that couples the first member and the second member. The first member and the second member are configured to move with respect to the connecting member so that the first member and the second member face each other. An interior channel disposed along the length is configured to receive a guidewire, and one or more guiding members are disposed on the first member and/or the second member bordering the interior channel and are configured to guide the guidewire into the interior channel.
The torque device further includes a locking member slidably coupled to the first member and/or the second member. The locking member is configured to move along at least a portion of the second side of the first member and the second member between one or more positions corresponding to one or more operation states, including a closed state in which the second side of the first member and the second side of the second member are fixedly secured with respect to the locking member, and one or more open states in which at least a portion of the second side of the first member and at least a portion of the second side of the second member are separated.
In certain configurations, the locking member has a first position corresponding to the closed state and open states including a first open state and a second open state. The first member includes a tip portion and a body portion, and the second member includes a tip portion, a first body portion, and a second body portion, with the first body portion between the tip portion and the second body portion. The positions correspond to separation along the second side and, for at least one open state, abutment of portions of the first and second body portions as the locking member moves into the corresponding position.
Claims Coverage
The document contains three independent claims. Across these claims, the inventive content is centered on a guidewire-receiving torque device with movable first and second members coupled by a connecting member, an interior channel bordered by guiding members, and a slidably movable locking member that creates closed and open operation states by securing or separating member portions, with additional structure defining multiple locking positions and stopping-member adjacency.
Guidewire-receiving torque device with interior channel and guiding members
A body includes a first member and a second member coupled by a connecting member, where the first member and the second member face each other, an interior channel disposed along the length is configured to receive a guidewire, and one or more guiding members are disposed on the first member and/or the second member bordering the interior channel, the one or more guiding members being configured to guide the guidewire into the interior channel.
Slidably coupled locking member defining closed and open operation states
A locking member slidably coupled to the first member and/or the second member is configured to move along at least a portion of the second side of the first member and the second side of the second member between one or more positions corresponding to one or more operation states, including a closed state in which the second side of the first member and the second side of the second member are fixedly secured with respect to the locking member, and one or more open states in which at least a portion of the second side of the first member and at least a portion of the second side of the second member are separated.
Tip and body portion configuration with position-dependent member separation and abutment
The first member includes a tip portion and a body portion; the second member includes a tip portion, a first body portion and a second body portion, the first body portion being between the tip portion of the second member and the second body portion; and the one or more positions includes a first position, a second position and a third position, where the first position corresponds to the closed state, the second position corresponds to the first open state in which the first body portion of the second member and the body portion of the first member are separated along the second side and the second body portion of the second member and the body portion of the first member are separated along the second side, and the third position corresponds to the second open state in which the first body portion of the second member and the body portion of the first member are separated along the second side and the second body portion of the second member and the body portion of the first member abut each other.
Discrete stopping-member positions for locking member adjacency
The one or more positions includes a first position and a second position; the body includes a plurality of stopping members disposed along the second side of the first member and/or the second member, the plurality of stopping members includes a first stopping member and a second stopping member; the locking member is configured to slidably move between the first stopping member and the second stopping member; the first position corresponds to when the locking member is adjacent to the first stopping member; and the second position corresponds to when the locking member is adjacent to the second stopping member.
Across the independent claims, the core claim coverage is a guidewire torque device in which movable first and second members define an interior channel bordered by guiding members, and a locking member slidably moves between closed and open operation states to secure or separate member portions. Additional independent-claim refinements define member-tip and body portion relationships that vary by locking position, and define discrete positions tied to adjacency of the locking member to stopping members disposed along the second side.
