Abstract: A system for treating a vascular condition, including an inflation adaptor having a housing, a clamping device positioned within the housing, and a medial v-groove alignment block. The clamping device includes a jaw and an anvil. An extended portion of a valve stem and a hollow guidewire are received in the medial v-groove alignment block. The extended valve stem and hollow guidewire are engaged by the clamping device to allow the extended valve stem and the hollow guidewire to be axially translated relative to each other to control a flow of an inflation fluid through the hollow guidewire when the clamping device is in a clamped position. A method of operation is also disclosed.

Abstract: A system for treating a vascular condition, including a hollow guidewire having a central lumen, a core wire received in the central lumen of the hollow guidewire and partially extended from a proximal end of the hollow guidewire, an inflatable balloon attached proximate a distal end of the hollow guidewire, a detachable inflation adaptor, and a clamping device. The inflation adaptor includes an axial insertion block having a funnel-shaped receiver to guide the extended core wire into the axial insertion block. The clamping device is axially aligned with the receiver. The extended core wire and the hollow guidewire are translated relative to each other to control a flow of inflation fluid into the inflatable balloon while the clamping device is in a clamped position. An inflation adaptor and a method of operation are also disclosed.

Abstract: The proposed meniscus suturing machine provides quick, strong, reliable sutures to torn medial menisci. An electronically controlled pneumatic system powers the suturing process. The meniscus suturing machine utilizes the chain stitch, a common sewing stitch, and applies it to the repair of torn menisci using only a single thread. The designed device is simple to use, with an on/off switch and fire button. While the device is simple, it has internal fault protection devices such as an automatic emergency shutoff and suture recovery loop. The device also comes apart easily, with a disposable needle-thread system. An autoclave sterilizes the remaining portion of the device. The initial application of the design is to suture medial menisci, but modifications will allow the suturing device to accommodate other areas too, such as the lateral meniscus. The benefits of the suturing device include a reduction in operating time and complexity of meniscus repairs.

Abstract: A rotary valve for a balloon catheter, including a hollow guidewire with a central lumen and a portion of a rotary shaft disposed within a guidewire proximal end. Rotating the rotary shaft of the rotary valve controls flow of an inflation fluid into and through the guidewire central lumen.
