  • Publication number: 20190167965
    Abstract: A device for reducing agent penetration at an insertion site is provided that has a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit. The device is stabilized by fibroblast in-growth and inhibits bacterial colonization. A device is also provided that has a conduit having a bore and an outer conduit surface. The outer conduit surface is optionally nanotextured to promote fibroblast adhesion and limit bacterial residency. A sleeve is provided in fluid communication with the bore of the conduit, and is formed from materials characterized by a pore matrix through which vacuum or hydrodynamic draw is achieved in a process to promote stabilization and reducing bacterial colonization by draw fluid from an area around the surrounding the site of the device. The sleeve optionally has a distal nanotextured surface.

  • Publication number: 20180207335
    Abstract: 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.

  • Publication number: 20170189663
    Abstract: A luminal access device is provided that includes a luminal graft attached to a patient lumen. A percutaneous access device (PAD) is coupled to the luminal graft and adapted to stabilize a conduit in fluid communication with the luminal graft and an external medical device. A portion of said PAD adapted to be external to the patient and seal around said conduit. Infectious agent penetration at an insertion site of the PAD is reduced by providing a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit to create a fluid draw from the subject tissue through the inner sleeve to the conduit. The conduit is readily formed to have a bore and an outer conduit surface, the outer conduit surface being optionally nanotextured. The conduit bore is adapted to accommodate a medical appliance.

  • Patent number: 9694122
    Abstract: 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.

  • Publication number: 20170172488
    Abstract: 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.

  • Patent number: 9498647
    Abstract: 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.

  • Patent number: 8877499
    Abstract: A biocompatible implantable bone anchor is provided that has a threaded first portion that engages and anchors into a bone. The implant also has a neck region extending from the first portion adapted to promote autologous cell growth thereon at an interface of the bone and one or more epidermal or gum layers, the neck region having a plurality of channels extending about the neck region. The neck region is configured to mechanically engage at least one of an abutment, dental restoration, or osseous device attachment. An in situ bone anchor cell growth assembly includes the bone anchor and a manifold encompassing the neck portion so as to form a seal therebetween and a route of fluid communication between a manifold inlet and at least one of said plurality of channels. A process for growing autologous cells on a neck region of a bone anchor is provided.

  • Patent number: 8578519
    Abstract: A protective barrier, such as a medical examination glove is provided that includes a bracelet defining a plane with a cylinder attached to the bracelet at a first end. The cylinder is compressed into a compressed conformation in the plane without rolling about the bracelet. When the barrier is a glove, three fenestrated caps are provided, each such cap attached to the cylinder at different locations along the length of the cylinder when said first cylinder is in an extended conformation. Multiple finger cylinders are each attached to the cylinder at a location of a fenestrated cap, the finger cylinders each having an end cap. The first cylinder and the finger cylinders each compressed into a compressed conformation in the plane such that each of the caps forms a portion of the surface of the plane.
