Thrombus detection device and method

A thrombus detection device comprising an elongate tube having at least one opening at a distal end of the elongate tube. A coupling is attached or formed at the proximal end of the elongate tube. The detection of the presence of a thrombus is performed by using a syringe to withdraw blood through the at least one thrombus detection opening at the distal end of the elongate tube. If little or no blood is withdrawn, or if the withdrawal of blood is more difficult than expected, the presence of a thrombus obstructing the openings is indicated.

Bone delivery apparatus and methods

Apparatus for delivery of bone includes a syringe body and a plunger. The syringe body includes a tip at a bottom thereof, a funnel-shaped top at the top thereof, and a tubular section having a generally cylindrical interior wall defining a passageway extending from the funnel-shaped top to the tip. The plunger includes an elongate piston, a press head, and a handle. The piston extends between the press head at a lower end of the plunger, and the handle at an upper end of the plunger. The plunger is removably received within the passageway, with an extent of the plunger extending out of the funnel-shaped top away from the syringe body. The syringe body may be loaded with one or more bone pellets or cartridges containing bone.

Tourniquet assemblies and systems, and methods for controlling tourniquets

A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.
