Patent number: 9387284Abstract: A system for assisting blood flow in a patient includes an implantable pump system for assisting in blood flow from the heart and an implantable control system for communicative connection with the implantable pump system. The control system includes a pacemaker system that is operative to control heart rate and the pump system interdependently to achieve a determined level of blood flow assist. The control system is adapted to increase the heart rate of the patient to above a normal heart rate for the patient under the present conditions of the patient via the pacemaker while controlling the pump system to achieve the determined level of blood flow assist based upon the increased heart rate and a level of assist provided by the pump system.Type: GrantFiled: October 21, 2014Date of Patent: July 12, 2016Assignee: VASCOR, INCInventors: Marlin Stephen Heilman, Douglas J. Koebler, Charles Robert Kohler, Jon David Wagner, David M. Reilly

Patent number: 8876686Abstract: In one aspect, an implantable pump system for assisting blood flow in a patient includes a blood flow path comprising a flexible conduit, at least one valve in fluid connection with the flexible conduit, a drive system in operative connection with the valve to move the valve in a reciprocating manner, an implantable control system and at least one sensor in communicative connection with the control system. The sensor is adapted to measure at least one property of blood. The control system is adapted to control movement of the valve on the basis of data regarding position of the valve with respect to time or a derivative thereof (that is, position, velocity, acceleration or a derivative thereof) in combination with data of the measured at least one property of blood from the sensor.Type: GrantFiled: February 9, 2012Date of Patent: November 4, 2014Assignee: Vascor, IncInventors: Marlin Stephen Heilman, Douglas J. Koebler, Charles Robert Kohler, Jon David Wagner, David M. Reilly

Publication number: 20130041460Abstract: An implantable pump system for assisting blood flow includes a conduit adapted to be placed in fluid connection with a blood vessel and at least one movable valve in fluid connection with the conduit. The valve includes at least one closure member in operative connection with an opening therein. The pump system further includes and an activating system adapted to actively move the closure member toward at least one of a closed position or an open position and a drive system to move the valve. The closure member can, for example, be biased toward an open position.Type: ApplicationFiled: February 9, 2012Publication date: February 14, 2013Inventors: MARLIN STEPHEN HEILMAN, DOUGLAS J.

Publication number: 20130041203Abstract: An implantable pump system for assisting blood flow includes a flexible conduit, at least one movable valve in fluid connection with the flexible conduit, a drive system comprising a rotary motor and a speed reducer operatively connected to the rotary motor; and a converter operatively connected to the drive system and operatively connected to the valve to drive the valve in a reciprocating linear manner. In a number of embodiments, the speed reducer includes a spur gear driving a ring gear, wherein the converter is operatively connected to the speed reducer.Type: ApplicationFiled: February 9, 2012Publication date: February 14, 2013Inventors: MARLIN STEPHEN HEILMAN, DOUGLAS J.

Patent number: 7588530Abstract: A pump includes a flexible conduit, at least one valve attached to the flexible conduit about the perimeter of the valve; and a drive mechanism to move the valve to pump blood within the conduit. The drive mechanism can, for example, be adapted to complete a single stroke during each heart ventricle contraction and/or to complete multiple strokes (that is, oscillate) during a single contraction. The moveable valve includes a plurality of openings. Each of the plurality of openings has a closure mechanism in operative connection therewith which is operable to at least partially close the opening to which it is operatively connected when the moveable valve is moved forward and to open the opening to which it is operatively connected when the valve is moved rearward. In one embodiment, each closure mechanism includes a flap of resilient material.Type: GrantFiled: July 19, 2005Date of Patent: September 15, 2009Inventors: Marlin Stephen Heilman, Douglas J. Koebler, Daniel R. Moore, Edward K. Prem

Patent number: 7258679Abstract: An inflow conduit of a ventricular assist device configured to prevent formation of recirculation and stagnation zones as well as collapse due to external forces or pump induced suction can be rigid and have a funnel like shape with an elbow to accommodate a patient anatomy. Stiffening elements and pressure sensing devices can also be provided associated with the inflow conduit.Type: GrantFiled: August 7, 2003Date of Patent: August 21, 2007Assignee: Vascor, Inc.Inventors: Daniel Richard Moore, Christopher David Capone, Marlin Stephen Heilman, Steve Andrew Kolenik, Carl Michael Parisi, Edward Karl Prem, Richard Andrew Sofranko

Patent number: 6942672Abstract: An apparatus and method for safely attaching a conduit to the heart, such as a conduit for connection to an implantable blood pump, or to a blood vessel, as in a heart bypass graft, without the need for a cardiopulmonary bypass. The apparatus can include an enclosure attachable to the heart and having sealed within the enclosure at least part of a coring tool and one end of the conduit which will be attached to the heart. A heart attachment member can be affixed to the enclosure for facilitating attachment of the apparatus to the heart and the coring tool can have a cutting member and a member for holding the tissue to be cut from the heart. All air can be evacuated from the enclosure prior to cutting tissue from the heart and attachment of the conduit.Type: GrantFiled: October 23, 2001Date of Patent: September 13, 2005Assignee: Vascor, Inc.Inventors: Marlin Stephen Heilman, Richard Andrew Sofranko, Carl Michael Parisi

Patent number: 6066085Abstract: A blood pump apparatus can include a pump housing having a drive chamber containing a drive mechanism. A cupped member can be connected to the housing and the drive mechanism can include a motor for rotating an eccentric shaft. A pumping arm can be provided having one end riding on the eccentric shaft, an intermediate portion pivotably attached to the housing and another end connected to a movable plate. A roller bearing can be mounted on the eccentric shaft on which the arm can ride. A compressible blood chamber having an inlet and an outlet connected can be provided sandwiched between the cupped portion and the movable plate. The motor thus rotates the cam causing the pumping arm to pivot which cycles the movable plate against the blood chamber to pump blood. The movable plate can be implanted adjacent a lung such that the lung moves with the plate as blood is pumped and thereby functions as a compliance chamber. A speed reducer can be provided between the motor and the eccentric shaft.Type: GrantFiled: July 22, 1999Date of Patent: May 23, 2000Assignee: Vascor, Inc.Inventors: Marlin Stephen Heilman, Christopher David Capone, Edward Karl Prem, Richard Andrew Zehel Sofranko, Carl Michael Parisi, Steve Andrew Kolenik, Daniel Richard Moore
