    摘要: A self-dilating cannula for introduction into a patient's vasculature includes an elongate body and an atraumatic tip. The elongate body has a proximal end, a distal end, and a fluid-flow lumen extending therebetween. The atraumatic tip is positioned at the elongate body's distal end and has a blunted end and a conical shape. The atraumatic tip includes a plurality of fluid-flow openings proximal to the blunted nose that are configured to disperse fluid from the fluid-flow lumen in a plurality of directions with respect to the atraumatic tip. The atraumatic tip also includes an opening in the blunted nose that is sized to a guidewire.

    摘要: This invention is a single, multichannel catheter useful for extracorporeal circulation of blood to a patient undergoing cardiovascular treatments or surgery. The catheter has three independent channels and an expandable balloon at one end of the catheter. The first channel (34) is the largest and is of a size that allows for delivery of blood to a patient in an amount sufficient to maintain the patient's metabolism and perfusion throughout the treatment or surgery. A second channel (36), smaller than the first, is integrated into the wall of the first channel, and is suitable for delivering a biologically active fluid (e.g., for cardioplegia) to the heart and/or venting the left heart. A third channel (38), also smaller than the first, is integrated into the wall of the first channel, and suitable for delivering a fluid to the balloon for its expansion when positioned in the ascending aorta to occlude the flow of blood to the heart. It is important that the first channel accounts for at least about 70% of the total channel volume. The catheter provides an improved means of performing cardiovascular surgery on a patient using a cardiopulmonary machine for extracorporeal circulation of blood. The catheter is particularly useful for cardiac surgery. The multichannel catheter is best prepared using an extrusion molding technique.

    摘要: A sizing plate for sizing a native valve annulus in a patient's heart for either valve replacement or repair during a minimally invasive surgical procedure is shown and described. The sizing plate is generally shaped such that it corresponds to the shape of the native valve annulus. Additionally, a thickness of the sizing plate is such that it can be inserted through a space between the ribs of the patient during the procedure. The sizing plate includes two keyways extending though the plate separated by a bridge. The keyways are sized and shaped such that they are adapted to be engaged by a minimally invasive surgical tool such as a laparoscopic grasper. The keyways in conjunction with the bridge facilitate manipulation of the sizing plate by the grasper from an external location.

    摘要: A centrifuge apparatus for processing blood comprising a bottom spring-loaded support plate; a top support plate; an axial inlet/outlet for blood to be processed and processed components of the blood, the axial inlet/outlet being attached to the top support plate by a rotating seal assembly; a variable volume separation chamber mounted between the bottom support plate and the top support plate, the variable volume separation chamber being fluidly connected to the axial inlet/outlet; a pump fluidly connected to the axial inlet/outlet; and a rotary drive unit attached to the bottom support plate. The top support plate is fixed vertically and the bottom spring-loaded support plate is mounted on springs that maintain pressure on the variable volume separation chamber and allow the bottom support plate to move vertically.
