A fabric, in the form of a woven or knitted fabric or garment, including a flexible information infrastructure integrated within the fabric for collecting, processing, transmitting and receiving information concerning-but not limited to-a wearer of the fabric. The fabric allows a new way to customize information processing devices to "fit" the wearer by selecting and plugging in (or removing) chips/sensors from the fabric thus creating a wearable, mobile information infrastructure that can operate in a stand-alone or networked mode. The fabric can be provided with sensors for monitoring physical aspects of the wearer, for example body vital signs, such as heart rate, EKG, pulse, respiration rate, temperature, voice, and allergic reaction, as well as penetration of the fabric. The fabric consists of a base fabric ("comfort component"), and an information infrastructure component which can consist of a penetration detection component, or an electrical conductive component, or both. The preferred penetration detection component is a sheathed optical fiber. The information infrastructure component can include, in addition to an electrically conductive textile yarn, a sensor or a connector for a sensor. A process is provided for making an electrical interconnection between intersecting electrically conductive yarns. Furthermore, a process is established for sheathing the plastic optical fiber and protecting it.

A braided self-expandable stent-graft-membrane made of elongated members forming a generally tubular body. A membrane layer and graft layer are disposed on a endoprosthesis such as a stent. The membrane layer is substantially impermeable to fluids. The outermost layer is biocompatible with the body tissue. The innermost layer is biocompatible with the fluid in the passage. An embodiment includes a graft layer disposed on the inside of a stent and a membrane layer disposed on the outside of the stent. The innermost layer is biocompatible with the fluid in the passage. The stent-graft-membrane is used at a treatment site in a body vessel or organ where it is desirous to exclude a first fluid located outside the endoprosthesis from reaching a second fluid located in the lumen. The membrane may be made of silicone or polycarbonate urethane. The graft may be braided, woven, spun or spray-cast PET, PCU, or PU fibers. The layers may include ePTFE or PTFE.

The present invention comprises a fabric-based sensor for monitoring vital signs or other electrical impulses of a subject. The sensor is woven or knitted from conductive fibers and, when in contact with the body, receives signals from the wearer and transmits them to a processing or monitoring device through a data-output terminal. The sensor may be integrated into the fabric of a garment or used independently as a conductive patch. Additionally, the sensor may provide bi-directional communication by both monitoring electrical impulses and sending them.

A wearable system or garment comprises at least three conductive electrodes that may, for example, be made of stretch-recovery electrically conductive yarns integrated with non-conductive stretch-recovery yarns that make up the remaining portion of the wearable system or garment. The wearable or garment further comprises means for using three electrodes to monitor at least one physiological or biophysical event or characteristic of the wearer. One electrode is specifically used to feed back an inverted noise signal to the wearer to destructively interfere with the wearer generated noise. Specifically, the wearer's heart rate, ECG and associated electrical characteristics may be monitored in high resolution under dry electrode conditions.

A circular knit tubing adapted for making a wearable article has a first knitted single layer tubular portion and a second knitted single layer tubular portion separated by a junction portion. The second tubular portion is folded over the first tubular portion at a fold line in the junction portion. The first and second tubular portions are then joined together, whereby the junction portion forms a band or welt. After the band is formed, the second tubular portion is folded back to cover the band. The wearable article may be a shirt having single layer top and bottom portions with a central double welt portion for physical contact around the wearer's chest or torso. The junction portion forming the band or welt preferably is integrally knitted with the first and second tubular portions. The band or welt defines a central opening to receive an electronic or electrical device or other component.

Textile-based electrodes include a fabric portion having stretch-recovery non-conductive yarns and an electrically conductive region having stretch-recovery electrically conductive yarn filaments. The electrodes can further include float yarns and can be configured in a textured or ribbed construction. When incorporated into a garment, the electrodes can be used to monitor biophysical characteristics, such as the garment wearer's heart rate.

The flexion area is an area where the tensile member is absent, and the flexion area may have the configuration of a space, aperture, or indentation, for example.

A blood flow diverter device for treatment of intracranial aneurysms, including a porous tubular member having a central portion and two ends. The member is of sufficient flexibility and body compatibility to be placed in proximity within an intracranial aneurysm. The central portion of the tubular member has a sufficiently decreased porosity to block blood flow from entering through the aneurysm. This is done by one of three methods: (1) the central portion of the member can be compressed to decrease porosity and heat set to hold the compression; (2) the angle of the fibers can be altered if the tubular member is made from a braided fibers; or (3) a monomeric coating can be formed on the central portion in an amount sufficient to decrease the porosity of the central portion upon polymerization of the monomeric coating. In the third embodiment a polymerization initiator is provided for polymerizing the monomeric coating upon command to cause the decreased porosity to block the blood flow. The device is heat set after compression to permit insertion and expansion in the patient. The tubular member has sufficient porosity at the two ends to keep open small perforator arteries proximate to the intracranial aneurysm.

Balloon catheter covers are elastic fabric structures of interconnected yarns, the structure having a high degree of stretch and recovery in the circumferential direction with little change in dimension in the longitudinal direction during multiple pressurization cycles over full range of inflation and deflation of the balloon catheter. The covers have longitudinal yarns positioned at about zero degrees to the balloon axis and reversibly-stretchable, circumferential yarns positioned at a high angle Ø to the axis. A method for making the balloon catheter covers allowing nearly orthogonal placement of circumferential and longitudinal yarns involves triaxial braiding a minimum number of elastomeric braid yarns with multiple axial yarns to provide maximum convergence angle (approaching 90 degrees).
