国際特許分類 (IPC) A61M 60/135 出願番号 93923927 出願人 JARVIK ROBERT K 発明者 JARVIK ROBERT K

A cannula pump (10) is provided which incorporates a miniature rotary pump into a cardiac cannula of essentially the same size as currently utilized with routine cardiopulmonary bypass. The pump may be inserted via a single small incision in the heart to obtain both inflow and outflow cannulation simultaneously, and provide sufficient flow to completely unload the ventricle during its use. Because application of the device is extraordinarily simplified, it is suitable for rapid emergency insertion in any setting where the chest can be safely opened, including emergency room and battlefield applications. A small electric motor (16), implanted within the heart, provides power to the impeller (36) via a small shaft (34) supported on blood immersed bearings (42). A disposable cannula pump utilized with a reusable motor provides an inexpensive device for routine surgical use.

国際特許分類 (IPC) A61M 60/863 出願番号 17695390 出願人 3R Life Sciences Corporation 発明者 Steven Shi Lap Tsui

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.

Apparatus is described including a blood pump (27) that includes an impeller (50) that has proximal and distal bushings (64, 58), and is configured to pump blood. A frame (34) is disposed around the impeller (50), a proximal bearing (116) is disposed proximally and a distal bearing (118) is disposed distally with respect to the impeller (50). An axial shaft (92) passes through the proximal and distal bearings (116, 118) and the proximal and distal bushings (64, 58). The axial shaft (92) is coupled to at least one of the proximal and distal bushings (64, 58) of the impeller (50), such that the at least one bushing is held in an axially-fixed position with respect to the axial shaft (92), and is not held in an axially-fixed position with respect to the proximal and distal bearings (116, 118). Other applications are also described.

A left ventricular assist device (20) is described including an impeller (50) configured to be placed inside a left ventricle of a subject and to pump blood from the left ventricle to an aorta of the subject, by rotating. A frame (34) is disposed around the impeller (50). A tube (24) is configured to traverse an aortic valve of the subject, such that a proximal portion of the tube is disposed within the subject's aorta and a distal portion of the tube is disposed within the subject's left ventricle. The distal portion of the tube (24) extends to a distal end of the frame (34) and defines one or more lateral blood inlet openings (108) that are configured to allow blood to flow from the subject's left ventricle into the tube (24). Other applications are also described.

Apparatus and methods are described including a blood pump (20) configured to be placed inside a body of subject, the blood pump including an impeller (50) that includes proximal and distal bushings (64, 58), and a frame (34) disposed around the impeller, the frame including proximal and distal bearings (116, 118). An axial shaft (92) passes through the proximal and distal bearings (116, 118) of the frame and the proximal and distal bushings (64, 58) of the impeller (50). The impeller (50) defines a radially-constrained configuration in which the impeller (50) is introduced into the subject's body and a non-radially-constrained configuration in which the impeller (50) is configured to pump blood within the subject's body. The impeller (50) changes from its radially-constrained configuration to its non-radially constrained configuration by the distal bushing (58) sliding over the axial shaft (92). Other applications are also described.

国際特許分類 (IPC) A61M 60/90 出願番号 18889744 出願人 MAGENTA MEDICAL LTD 発明者 Yosi TUVAL

Apparatus and methods are described including a blood pump that includes a pump-outlet tube shaped to define one or more blood-outlet openings and configured for insertion into a heart of a subject. An impeller is disposed within a distal portion of the pump-outlet tube and is configured to pump blood of the subject proximally through the pump-outlet tube, such that the blood exits the pump-outlet tube through the blood-outlet openings. A delivery tube extends, from outside a body of the subject, through the pump-outlet tube to the distal portion. A drive cable passes through the delivery tube and is configured to rotate the impeller. A proximal portion of the pump-outlet tube includes multiple strips adhered to the delivery tube. Other embodiments are also described.
