Assemblies are provided for positioning within a lumen comprising a stent graft; and a sensor positioned on the stent graft. Within certain aspects the sensors are wireless sensors, and include for example one or more fluid pressure sensors, contact sensors, position sensors, pulse pressure sensors, blood volume sensors, blood flow sensors, chemistry sensors (e.g., for blood and/or other fluids), metabolic sensors (e.g., for blood and/or other fluids), mechanical stress sensors and/or temperature sensors.

Medical devices are provided, comprising a medical device and a sensor.

Some implementations of an endovascular device include a stent graft with an expandable tubular metallic frame and a covering material disposed on at least a portion of the metallic frame. The stent graft defines a lumen therethrough. In a particular embodiment, a first balloon is disposed around an outer periphery of the stent graft, a second balloon is disposed around the outer periphery of the stent graft and spaced apart from the first balloon, and a third balloon is disposed within the stent graft lumen between the first balloon and the second balloon. The third balloon can be inflated to fully or partially occlude the lumen. The first and second balloons can be individually inflated to fully or partially shunt blood flow from a blood vessel through the stent graft. In some embodiments, sensors and an automated control unit are included to automate the operations of the endovascular device.

Devices for measuring and communicating physiological data are described. An implanted biocompatible sensor may be utilized to wirelessly communicate with an external transceiver. The biocompatible sensor may include a tubular body, one or more biomedical sensing elements coupled with the tubular body, and a microprocessor in electronic communication with the one or more biomedical sensing elements. The biocompatible sensor may also include an antenna coupled with the tubular body. The transceiver may be in electronic communication with the microprocessor via the antenna and may be configured to power the microprocessor using inductive radio frequency energy.

A universal implantable integrated circuit medical device platform having integral and monolithic circuit traces. The platform allows for implanting into a mammalian body single and multi-functional interface devices for sensing, monitoring stimulating and/or modulating physiological conditions within the body. Microelectronic circuitry may be integrated onto the platform or may be joined as modular components to the platform.

Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal, for stimulating and/or sensing activity of media proximal to the device, wherein the media includes tissue and/or fluid.

A stent apparatus for use in surgical applications having a hollow tubular section with a proximal end and a distal end. Additionally, the stent apparatus can have at least one anchor point connected to the hollow tubular section. The hollow tubular section may also have a modifiable member, and a magnetic connection node. The stent may also be wrapped in a material that has magnetic properties. The delivery of the stent can include a stent delivery tool for inserting a stent into a vessel.

A stent apparatus for use in surgical applications having a hollow tubular section with a proximal end and a distal end. The stent apparatus may also have a plurality of radially extending anchoring points centrally located between the proximal and distal ends. The stent being compressible can also include a sheath that is of a material that can be pulled away to remove it from the stent and deploy the stent and the plurality of radially extending anchoring points.

A stent delivery apparatus and/or system including a hollow tubular body with a proximal opening at a proximal end of the hollow tubular body and a distal opening at a distal end of the hollow tubular body. The hollow tubular body can define the proximal opening and the distal opening. A support rod can be passed through the proximal opening and/or the distal opening. The support rod may have a tip, and tip can be olive shaped. A stent may be supported by and/or surround the support rod. The tip of the support rod may also engage with the stent during delivery.

A stent apparatus, system, and method that senses wall shear stress by measuring fluid flow at localized areas within the stent, that processes measured information through an integrated circuit, and selectively sends power to mechanically controllable stent surfaces which results in localized geometric changes. In various embodiments the stent apparatus, system, and method sends data to outside the body in real time.
