Abstract: A device for inferior retrieval of a vena cava filter includes an outer sheath with a first radial window closer to the distal end than the proximal end of the outer catheter; an inner sheath generally extending movably inside the lumen of the outer sheath and having a second radial window; and a snare tool having an elongated guide element extending through the inner sheath and a snare loop distally attached to the guide element. The snare loop is extendable outward through the two radial windows.

Abstract: A management system is used for management of patients on waiting lists in such fields as elective surgery, diagnostic services, clinic services and endoscopies. The system also administers administrative entities based on aggregate data provided by the system. The system has data entry, list management, audit and reporting functions. It acquires and creates its data. It calculates much data dynamically (in real time). For example, it stores data on when a patient entered onto a waiting list, and a patient's urgency score. Based on the urgency score, it calculates a target date for the patient. It dynamically (in real time) calculates the number of days a patient is from the target date, and ranks the patients accordingly. It filters a list of patients awaiting procedures according to various resource criteria. It provides for and manages referrals between systems, and lists, in different fields, and it allows calendar booking.
