Abstract
An elongate shaft management device has an upper plate and a lower plate. The lower plate has at least one groove that is sized to receive the elongate shaft. The at least one groove in the lower plate cooperates with the upper plate to capture the elongate shaft and prevent movement of the elongate shaft. The upper plate is releasably coupled to the lower plate to provide access to the elongate shaft and allow it to be manipulated.
Core Innovation
The invention relates to a guidewire or catheter shaft management device comprising an upper plate and a lower plate, each having at least one groove disposed therein. The upper plate comprises at least one upper groove sized to receive a guidewire or catheter shaft, and the lower plate comprises at least one lower groove sized to receive the guidewire or catheter. When the upper plate and lower plate cooperate, the upper and lower grooves form a channel configured to hold the guidewire or catheter shaft.
The upper plate is detachably coupled to the lower plate, and the guidewire or catheter is capturable between the upper plate and the lower plate. The upper and lower plates have alignment pins and apertures, with each alignment pin received in a corresponding aperture when the upper plate is coupled to the lower plate. The upper plate and the lower plate are configured such that the upper plate can be completely detached from the lower plate to allow access to a guidewire or catheter shaft received in the channel.
In a described configuration, the at least one lower groove comprises a first lower groove and a second lower groove disposed in the lower plate, extending from a first edge of the lower plate to a second edge opposite the first edge. Adjacent the first edge, the first and second lower grooves are substantially parallel with one another, and adjacent the second edge, the first and second lower grooves flare away from one another in respective curved arcs that diverge away from one another.
The described management includes disposing the guidewire or catheter shaft in the at least one lower groove in the lower plate and apposing the upper plate against the lower plate to capture and constrain movement of the guidewire or catheter shaft therebetween.
Claims Coverage
The document includes two independent claims: a device claim and a method claim. Across these, the core inventive content includes five inventive features involving a detachably coupled upper plate and lower plate, aligned grooves forming a channel, registration features, complete detachment for access, and a specific lower groove geometry.
Detachably coupled upper and lower plates forming a channel
An upper plate comprising at least one upper groove sized to receive a guidewire or catheter shaft; a lower plate comprising at least one lower groove sized to receive the guidewire or catheter; wherein the upper plate is detachably coupled to the lower plate and the guidewire or catheter is capturable between the upper plate and the lower plate, and the at least one lower groove cooperates with the at least one upper groove to form a channel configured to hold the guidewire or catheter shaft.
Alignment pins and apertures for registration when plates are coupled
The upper and lower plates have alignment pins and apertures, with each alignment pin received in a corresponding aperture when the upper plate is coupled to the lower plate.
Complete detachment for access to a shaft in the channel
The upper plate and the lower plate are configured such that the upper plate can be completely detached from the lower plate to allow access to a guidewire or catheter shaft received in the channel.
Parallel-to-flared curved arc groove geometry in the lower plate
The at least one lower groove comprises a first lower groove and a second lower groove disposed in the lower plate, extending from a first edge of the lower plate to a second edge opposite the first edge, with the first and second lower grooves substantially parallel adjacent the first edge and flaring away from one another in respective curved arcs adjacent the second edge.
Apposing the upper plate to capture and constrain movement
A method of providing the guidewire or catheter shaft management device, disposing the guidewire or catheter shaft in the at least one lower groove in the lower plate, and apposing the upper plate against the lower plate to capture and constrain movement of the guidewire or catheter shaft therebetween.
The independent claims are directed to a management device and method in which a guidewire or catheter shaft is captured between an upper plate and a lower plate that are detachably coupled. Grooves in the upper and lower plates cooperate to form a channel, alignment pins and apertures register the coupled plates, the upper plate can be completely detached for access, and the lower groove geometry is described as substantially parallel near one edge and flaring in diverging curved arcs near the opposite edge.
Stated Advantages
Holds the guidewire or catheter shaft in a channel configured to hold the shaft.
Captures and constrains movement of the guidewire or catheter shaft when the upper plate is apposed against the lower plate.
Allows access by completely detaching the upper plate from the lower plate to allow access to a guidewire or catheter shaft received in the channel.
Documented Applications
Managing a guidewire or catheter shaft using a guidewire or catheter shaft management device.
