Publication number: 20180207335Abstract: A cardiac pump and an assist system is provided that increases blood ejection from a compromised heart. An implantable cardiac pump acting as an assist device provided includes an attachment system and locating features that enable a minimally invasive procedure to implant and deploy one or more aortic blood pumps in a patient. The insertable cardiac pump is replaceable without resort to a conventional open surgical procedure. Monitoring of cardiac pump operation allows for replacement in advane of chamber failure. The dynamics of blood-contacting interface of the cardiac assist device mimic the dynamics of the blood-contacting interface of a naturally occurring left ventricle, thereby minimizing flow-related device-associated pathologic disturbances of intravascular clotting mechanisms.Type: ApplicationFiled: July 22, 2016Publication date: July 26, 2018Inventor: Allen B.

Patent number: 9694122Abstract: An implantable aortic blood pump includes a rigid body having wall extending along a long axis and defining an inflation port portion with an inflation aperture therethrough. The aperture is fluid communication with an inner surface of the body and on a fluid supply, the body is preferably independent of an external brace or an external stiffener, yet still has a cantilevered deformation of less than 8 millimeters in response to a 200 gram weight suspended from a front body edge. A deflecting structure of a membrane deflects in response to fluid pressure so as to pump blood when the pump is secured to a subject aorta.Type: GrantFiled: May 13, 2014Date of Patent: July 4, 2017Assignee: L-VAD Technology, Inc.Inventors: Robert M Smith, Adrian Kantrowitz, Valluvan Jeevanandam, Allen B.

Publication number: 20170172488Abstract: A system for measuring and monitoring wound hermaticity of a patient is provided that includes one or more sensors for measuring parameters that correlate to a degree of wound hermaticity, where the one or more sensors are incorporated into the design of a percutaneous skin access device (PAD), a bone anchor, a wound dressing, or a bandage. The degree of wound hermaticity is related to impedance measurements performed on the patient's skin, via measurements of humidity in a vacuum line to the PAD or the bone anchor, or via measurements of local tissue oxygenation in the immediate vicinity of the PAD or the bone anchor interface with the patient's skin. The hermaticity measurement parameters are communicated by wired or wireless connection to a computing or a communication device for immediate or remote monitoring.Type: ApplicationFiled: March 12, 2015Publication date: June 22, 2017Inventors: Allen B.

Patent number: 9498647Abstract: A system is provided for subject movement compensation during a medical procedure. The system uses passive radiofrequency identification tags associated with a subject, and at least one active RFID reader is positioned to interrogate the position of at least three such passive radiofrequency identification tags so as to triangulate the geometric position of a subject body tissue. The reader generates an output signal corresponding to a distance between said reader and a tag. A microprocessor calculates a displacement of a tag relative to the reader from said output signal to yield a value corresponding to subject movement. A medical device operates in synchronicity with the calculation corresponding to subject movement to compensate for subject movement during a treatment process in essentially real time. A process for subject movement compensation during a medical procedure is also provided.Type: GrantFiled: September 25, 2006Date of Patent: November 22, 2016Inventors: Allen B. Kantrowitz, In K. Mun
