Abstract: An inflow cannula assembly intended for connecting a ventricular assist device (VAD) to a heart chamber without suturing anastomosis is provided. The inflow cannula assembly includes a deformable flow cannula with funnel-shaped bellmouth intake at a first end and a second end interfaced to the inlet of a VAD with minimal interface discontinuity; also includes is a pair of male and female fasteners that can be screw locked to fix and seal the cannula bellmouth against the endocardium for hemostasis purpose; as well as a VAD coupler and a VAD inlet adapter that enable a quick connection of the cannula with the VAD.

Abstract: A surgical suture holder is adapted to be disposed on an opening of a tubular snaring object, is adapted for holding at least one surgical suture, extends along a holder axis, and includes an insertion section and a holding section. The insertion section is adapted to be inserted into the opening of the tubular snaring object and being tapered toward the tubular snaring object. The holding section has a holding board that has a periphery surrounding the holder axis, and at least one holding slot that is recessed from the periphery of the holding board, that extends through the holding board in an extending direction of the holder axis, and that is adapted for the at least one surgical suture to fit thereinto so that the holding slot holds the at least one surgical suture.

Abstract: An implantable circulatory support system, configured to connect a ventricular chamber of a heart, including a valveless displacement blood pump, a deformable polymeric flow cannula, a pair of male and female fasteners, a coupler, a driveline assembly, and a co-pulsatile driver. Forward and backward flow communication between the blood pump and the heart chamber is accomplished using the present flow cannula invention which is anastomosed to the heart chamber in a sutureless manner. When providing circulatory support, the co-pulsatile driver ejects blood out of the blood pump during systolic ventricular contraction and fills the blood pump with blood during diastolic ventricular relaxation.
