Patent number: 9393357Abstract: An extracorporeal blood perfusion system includes a disposable assembly and a control unit having a control interface region. The interface region includes pump assemblies for selective pumping of venous blood, arterial blood, cardioplegia solution, suctioned blood and blood removed from the left ventricle. Valve assemblies control the flow of fluids through the assembly and to/from the patient and sensors monitor various fluid parameters including temperature and pressure within the various fluid circuits. The user interface is a functional screen interface for effecting the operation of the control unit and valve assemblies. The screen interface may be a touch screen having objects that corresponds to the component interface region. The display may be selectively controlled to provide graphic depictions of disposable assembly components with corresponding narrative instructions.Type: GrantFiled: December 13, 2013Date of Patent: July 19, 2016Assignee: Sorin Group USA, Inc.Inventors: Bruce S.

Patent number: 9339599Abstract: 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.Type: GrantFiled: December 20, 2010Date of Patent: May 17, 2016Assignee: Sorin Group USA, Inc.Inventors: Tamer Ibrahim, Jeffrey P.

Patent number: 9149207Abstract: 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.Type: GrantFiled: October 16, 2013Date of Patent: October 6, 2015Assignees: Sorin Group USA, Inc., The Trustees of the University of PennsylvaniaInventors: Joseph A. Sauter, W. Clark Hargrove, III

Publication number: 20120215202Abstract: An extracorporeal circulation catheter has three independent channels and an expandable balloon at one end of the catheter. The first channel 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. The second channel is integrated into the wall of the first channel and is suitable for delivering a fluid (e.g., for cardioplegia) to the heart. A third channel is integrated into the wall of the first channel and is 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. The first channel accounts for at least about 70% of the total channel volume.Type: ApplicationFiled: February 27, 2012Publication date: August 23, 2012Applicant: Sorin Group USA, Inc.Inventors: Arthur A.

Patent number: 8123737Abstract: 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.Type: GrantFiled: November 23, 2004Date of Patent: February 28, 2012Assignee: Sorin Group USA, Inc.Inventors: Arthur A.
