    摘要: A co-axial filtering device for removing particles from arteries and veins comprises an outer catheter that can be inserted into a blood vessel and an inner catheter with a filter at its distal end. The filter is a radially expandable receptacle made of an elastic mesh structure of spring wires or plastic monofilaments. The filter expands into engagement with the walls of the blood vessel when it is pushed from the distal end of the outer catheter. A syringe is attached to the proximal end of the inner catheter and particles entrapped within the filter are aspirated through the inner catheter into the syringe. When filtering is no longer necessary, the filter can easily be removed by pulling the elastic material through the outer catheter.

    摘要: The present invention provides a method for creating a computer model of a patient specific joint for treatment planning. The method includes identifying a ligament of a joint of a patient under a load at a predefined position of the joint. The method further includes constructing, with the use of a computer, a computer model of the joint of the patient having: a first bone model, a second bone model, and a ligament model connecting the first and second bone models corresponding to the identified ligament, wherein the ligament model is constructed as at least one fiber based on a predefined slack length.

    摘要: A system for controllably turning over a patient in a bed includes a flexible body sling and a ratchet device. The flexible body sling includes a main torso portion that terminates in a first end and an opposing second end and is configured for placement under the patient between a head and a tailbone of the patient. The flexible sling has a first sling strap that is coupled to the first end and a second sling strap that is coupled to the second end. The ratchet device has a mount that includes a curved portion for placement over a side rail of the bed to detachably secure the ratchet device to the bed. The ratchet device has a rotatable spool with a slot for receiving one of the first sling strap and the second sling strap. The ratchet device has a pivotable handle for driving the rotatable spool.
