Abstract: The invention provides a method of monitoring platelet function in a mammal by passing blood removed from the body of the mammal through a passageway to contact an obstruction or irregularity in the passageway to generate a platelet mass in the passageway, and monitoring the flow or composition of the blood in the passageway to detect the platelet mass. The flow and composition change in response to the formation of a platelet mass in the passageway. Devices, articles, and kits for performing the methods are also disclosed.
Abstract: An autotransfusion device having: a first line and a first pump, the first line being connected to the inlet of a blood centrifugation cell, and branches of the first line being (i) connected to a red blood cell container, (ii) provided with a coupling, and (iii) being suitable to be connected to the patient; a second line connected to the outlet of a blood centrifugation cell and two branches of the second line being provided with two couplings; and a third line and a second pump, the third line being connected to the first line in an intermediate position between the first pump and the blood centrifugation cell, and branches of the third line (i) being connected to a physiological solution container and (ii) being provided with a coupling.
Abstract: An exercise device and method of use thereof, including an exercise platform and an incline base that can be used together or separately. The exercise device can be used for aerobics, strength-training and yoga or a combination thereof. The exercise platform can be rectilinear U-shaped and can include pull rings and exercise tubes connected thereto and the incline base can be adjustable from a horizontal position to variable degrees of incline.
Abstract: A device for treating blood in an extracorporeal blood circuit, the device including a centrifugal pump provided with a transparent enclosure that is connected, by means of an inlet duct, to the outlet of a venous reservoir, the venous reservoir having an inlet that is connected to receive blood from a patient. The transparent enclosure of the pump is connected monolithically to the base of a structure that comprises a heat exchanger and an oxygenator. The structure also supports monolithically, at the peripheral region, an arterial filter that receives the blood in output from the oxygenator and is provided with a connector for coupling to an arterial line for return of the blood to the patient.

Abstract: A retaining wall block (1) has parallel top and bottom faces (2, 3), a front face (4), a rear face (5), first and second side wall faces (6, 7) and a vertical plane of symmetry (S) extending between the front and rear faces (4, 5). The block (1) is formed as a body portion (8) including the front face (4), a head portion (9) including the rear face (5) and a neck portion (10) connecting the body portion (8) and the head portion (9). The body, head and neck portions (8, 9, 10) each extend between the top and bottom faces (2, 3) and between the first and second side wall faces (6, 7). An opening (13)? extends through the neck portion (10) from the top face (2) to the bottom face (3), dividing the neck portion (10) into first and second neck wall members (14, 15) extending rearwardly from the body portion (8) to the head portion (9).

Abstract: The present invention provides for a local drug delivery mechanism for use with a protection device. An infusing device is used to charge the drug into the catheter lumen toward a distal portion of the lumen having a plurality of drug delivery exit ports. The drug exits the ports into the patient's vascular system and is able to flow toward a filter maintaining the patency of the filter.

Abstract: A method of coating a pre-formed trainable material, such as nitinol wire, with a heat resistant substance, heat treating, and cooling to form a desired shape. The substance can be removed by various methods after heat treatment, depending upon the composition of the substance. The method includes forming a trainable material around a mold that dissolves, vaporizes, or can otherwise be removed. The method is useful for forming complicated shapes that would be expensive or impossible to form by conventional methods.

Abstract: Therapeutic devices that provide support or pressure to tissue. Devices contain a material that is capable of being contracted from its relaxed state to an evacuated state. The material applies pressure to the tissue of a patient when the material is in its relaxed state. Reduction of pressure by application of a vacuum results in a contracted state of the device, so that the device can be applied or delivered to a patient. Release of vacuum results in a return to the relaxed state, thus providing a maximum desirable pressure to tissue and avoiding the possibility of over-pressure which can result in tissue damage or necrosis.
Abstract: A distal protection device for use in a body lumen. The device includes a functional element which may be a filter or an occlusive element. The device includes means for controlling the movement and placement of the functional element along a guidewire. Motion of the guidewire can be independent of the motion of the functional element.
