Abstract: An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a plurality of pinhole leaks or a slit leak of a mitral valve. A plurality of orifice locations of a leaking valve are identified and Doppler values obtained from a flow velocity field proximal each orifice. The Doppler values of each flow velocity field vectorially relating to the orifice location are processed to produce a measure of flow through the orifice. The flow measurements for a plurality of such orifices are summed to produce a quantified measure of regurgitant flow through a plurality of pinhole leaks or along a slit leak.

Abstract: An annuloplasty ring, configured for implantation in the annulus of a heart valve, comprising multiple segments each of which are geometrically shaped from a three dimensional perspective to conform to the anatomic shape of the valve annulus. In one embodiment, at least one of the multiple segments of the annuloplasty ring is configured to facilitate a reduction of tension on heart valve tissue and eliminate a substantial portion of potential pressure or force that may be applied to the atrio-ventricular node by the annuloplasty ring when inserted into a heart valve. In another embodiment, at least one of the multiple segments of the annuloplasty ring are configured to include an assembly that facilitates selective adjustment of a segment's respective length and/or shape. The adjustment of the length of one of the ring segment's results in an adjustment of at least one angle between at least one set of other ring segments, thereby causing an adjustment to the geometric characteristics of the ring.

Abstract: An apparatus (100) for and a method of delivering and implanting a surgical device on an anatomic structure is through minimally invasive procedures. The method is facilitated by an apparatus including a unitary tube (106) operatively connected to a deployment head (118) controlled by an apparatus controller. The deployment head is configured to deploy suture hooks or similar clips that connect an annuloplasty implant to heart tissue and secondary surgical devices to the annuloplasty implant. The apparatus is further configured to facilitate orientation adjustment or collapsing of the deployment head and surgical devices attached thereto in order to facilitate their passing through an incision smaller than generally required. After the deployment head passes through the incision its orientation is readjusted so that it may be positioned and the annuloplasty implant automatically sutured to a heart valve annulus by the apparatus suturing sub-assembly using the suture hooks.

Abstract: A device for use in combination with a fluid flow having a biologic component and subject to an adverse response to shear stress includes a surface in contact with the flow of the fluid. The surface has a longitudinal direction extending from a leading end toward a trailing end and aligned with a direction of the flow. The surface is susceptible to inducing boundary layer formation within the flow sufficient for a resulting shear stress to induce the response. The surface includes a surface feature sufficient to induce boundary layer tripping in the flow to retard growth of boundary layer formation along the length.

Abstract: A novel system and method for fluid management for accurate continuous venovenous hemofiltration (CWH) in extracorporeal membrane oxygenation (ECMO). The fluid management or CWH system is automated and configured for operation as a stand alone unit and can be easily integrated with an ECMO system. The fluid management system is capable of producing either perfect or negative fluid balance between ultrafiltrate removal and replacement fluid delivery. The fluid management system can achieve electrolyte replacement over a range of flow rates needed to care for patients ranging from neonates to adults. Finally, the novel fluid management system preserves patient safety, maintains sterility during operation, is easy to operate, and is compact enough to fit near a patient's bed.
