An external protective interface is provided for intravenous infusion lines, drive lines, vacuum lines, and monitoring lines for percutaneous access. The interface acts as an airtight seal in concert with a vacuum line to promote accelerated tissue healing to reduce and prevent infection at insertion sites for infusion lines, drive lines, and medical devices. The interface provides additional mechanical stability to an implanted tube or PAD or so as to speed healing around a semi-permanent implanted tube or PAD, as well as connection points for vacuum lines and at least one drive line for the insertion of medical devices. The dense fibroblast ingrowth encouraged by the interface acts to strengthen barriers to infection at the insertion site.

The present invention relates to novel tools and systems that provide a precision platform for professional health-related (PHR) communication where clinical relevance is standardized for the achievement of clinical precision. In particular, the present invention provides methods, tools, and systems using precision architecture control structure (PACS) comprising professional health-related (PHR) structured dialogs suitable for precise clinical diagnosis, in combination with encrypted transmission which is capable of HIPAA compliant communication of a healthcare information system with a credentialed user. The increased clinical precision of these tools, systems, and related methods affords greater efficiency in clinical treatment that is translated into increased safety in patient care, which extends far beyond simple communication of clinically relevant information.

An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. A navigation system is provided to control the at least two actuators. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of &#xb1;1.0 mm and &#xb1;1.0&#xb0;, or better in patient tissue.

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.

Vacuum assisted percutaneous appliance

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 advance 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. A process of operating a cardiac assist device includes cyclically inflating and deflating one or more inflatable cardiac pumping chambers with timing and parameters as to pressure, deflection, and speed of inflation to in crease patient cardiac output.

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.

Active hermeticity monitoring

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.

An inventive digestive tract barrier includes a material defining dimensions of a tube sized to deploy within the digestive tract of a subject. The material or stitches that make up the barrier disintegrate in a controlled manner. The disintegration precludes the need for a surgical procedure to retrieve the barrier and allows for increased nutritional absorption after behavior modification has occurred. Through the inclusion of opening or fenestrations in the barrier, bile flow and nutrition absorption are facilitated. Disintegration is facilitated by formation of the barrier from biodegradable material, stitching non-degradable swatches with disintegrating stitching, or the use of a MEMS cutter. A digestive barrier coated on either the interior or exterior of the tube facilitates management of conditions such as obesity, colitis, and Crohn's disease.

A navigation system is provided to control the at least two actuators. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of 1.0 mm and 1.0?, or better in patient tissue.

A cardiac assist device is provided that can be deployed in any region of the aorta by minimally invasive techniques by the way of an inventive fastener that affixes the device to the aorta wall at the site of an aortonomy. The devices and methods described herein allow for improved patient outcome.

Cardiac assist device, instruments, and methods

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.

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.
