Implantable in vivo sensors used to monitor physical, chemical or electrical parameters within a body. The in vivo sensors are integral with an implantable medical device and are responsive to externally or internally applied energy. Upon application of energy, the sensors undergo a phase change in at least part of the material of the device which is then detected external to the body by conventional techniques such as radiography, ultrasound imaging, magnetic resonance imaging, radio frequency imaging or the like. The in vivo sensors of the present invention may be employed to provide volumetric measurements, flow rate measurements, pressure measurements, electrical measurements, biochemical measurements, temperature, measurements, or measure the degree and type of deposits within the lumen of an endoluminal implant, such as a stent or other type of endoluminal conduit. The in vivo sensors may also be used therapeutically to modulate mechanical and/or physical properties of the endoluminal implant in response to the sensed or monitored parameter.

Disclosed herein a liposuction cannula that comprises a tube with a front end at which there is provided at least one suction opening, and with a back end intended to be connected to a source of vacuum; in the tube there being defined at least one longitudinal flow conduit for the aspirated material; and an imaging apparatus capable of supplying first signals or data allowing the generation of a visual representation of the environment in close proximity to the front end of the tube of the cannula down to a first depth or distance, and second signals or data allowing the generation of a visual representation of the environment around the front end of the tube of the cannula down to a second depth or distance, greater than the said first depth or distance.

Method and system for providing continuous calibration of analyte sensors includes calibrating a first sensor, receiving data associated with detected analyte levels from the first sensor, and calibrating a second sensor based on a predetermined scaling factor and data associated with detected analyte levels from the first sensor, is disclosed.

Detection systems and methods configured to scan and interpret a suspected infection at in vivo biological target site, comprising emitting excitation light selected to elicit fluorescent light from a suspected infection at the target site; sensing fluorescent light emanating from the target site elicited by such excitation light; sensing heat levels above ambient body temperature emanating from the target site; and then based at least in part on the sensed fluorescent light and the heat levels, determining a probability whether the target site comprises an infection.

A device for retarding birth including an upper ring for surrounding a cervix, an anchoring component for anchoring the device, and an elastic component for attaching the upper ring to the anchoring component, wherein the elastic component pushes the upper ring and the anchoring component apart. A device for retarding birth including a sleeve for surrounding a cervix along a greater portion of a length of the cervix, a support strip on the sleeve directed along an axis of the sleeve, and a ring at least partially around the sleeve, in which when a top of the sleeve is pushed to expand radially, the support strip pivots on the ring, such that an end of the support strip near the top of the sleeve moves radially outward, and an end of the support strip near the bottom of the sleeve moves radially inward. Related apparatus and methods are also described.

A method of monitoring cardiac dysfunction, such as pericardial effusion, is disclosed. The method uses an indwelling probe inserted within a coronary sinus or a chamber or vessel of the heart, the probe having motion sensing means configured to sense motion of the probe based on movement of the wall of the coronary sinus or other chamber or vessel. Data is obtained from the motion sensing means and processed to monitor for cardiac dysfunction. The monitoring can be in real-time and can utilise one or more three-axis accelerometers. In some embodiments, two or more three-axis accelerometers are spaced longitudinally along an elongate body of the probe, which can increase accuracy and reliability of monitoring.

A secondary battery includes a substrate defining first and second through holes; a battery cell on the substrate and including a positive electrode, a separator and a negative electrode; an adhesive layer on the substrate and together with the substrate and the battery cell, removably attachable to an object outside of the secondary battery; a first electrode terminal including a first end electrically connected to the positive electrode and a second end which is opposite to the first end electrically connected to the positive electrode and exposed to the outside of the secondary battery at the first through hole; and a second electrode terminal including a first end electrically connected to the negative electrode and a second end which is opposite to the first end connected to the negative electrode and exposed to the outside of the secondary battery at the second through hole.

Methods, sensors, and systems that prevent or reduce data loss when more than one external sensor transceiver is used with a sensor. A sensor may receive a transceiver identification (ID) of an external transceiver conveyed from the external transceiver and determine whether the received transceiver ID is a new transceiver ID. If sensor determines the received transceiver ID to be a new transceiver ID, the sensor may store the received transceiver ID in a nonvolatile storage medium of the sensor and convey, using the sensor, measurement information stored in the nonvolatile storage medium to the external transceiver.

Methods for fabricating implantable cuff electrodes for contacting or at least partially surrounding internal body tissue such as, e.g., nerves, smooth muscles, striated muscles, arteries, veins, ligamental tissues, connective tissues, cartilage tissues, bones, or other similar body tissues, structures and organs are disclosed. An example method includes preparing a substrate including an implantable cuff electrode shape, applying a mold material to the substrate, curing the mold material to form a mold, releasing the mold from the substrate, inserting at least one conductor into the mold that penetrates through the channel of the mold, pressing a formable material into the channel of the mold to form a body of an implantable cuff electrode about the at least one conductor, curing the body of the implantable cuff electrode, and releasing the body of the implantable cuff electrode from the mold.

An example implantable connector for connecting an electronics package and a neural interface is made by way of a set of compressible contacts (e.g., springs) that physical contact a set of corresponding exposed bond pads. The compressible contacts are held in compression with the exposed bond pads using a mechanical coupler. The compressible contacts are physically separated and electrically isolated from each other by way of a compressible gasket. The compressible gasket is also held in compression using the mechanical coupler.
