Abstract:
A catheter (32) is disclosed that comprises an expansion element (34b) comprising a plurality of electrodes (36 1-N). The expansion element is configured to expand within a heart chamber so that at least a portion of the plurality of electrodes contact a wall of the chamber and a plurality of electrograms can be determined at substantially the same time in response to an electrical perturbation. The catheter may comprise pacing electrodes (82 1-M) to provide the perturbation. An activation map of the chamber can be determined based on the plurality of electrograms. Based on the activation map, a location and a shape of a mechanism of action of an arrhythmia can be determined and a treatment plan can be developed. For example, the treatment plan can include guiding an ablation of the mechanism of action.
Abstract:
A system for delivery of radiation to a target portion of a native tissue is provided. The system includes a catheter having a main catheter body. The main catheter body includes an outer catheter surface and an inner catheter surface that defines a longitudinally oriented lumen. The lumen extends between longitudinally spaced proximal and distal catheter face surfaces extending laterally between the inner and outer catheter surfaces. A sheath covers at least a portion of the outer catheter surface. The sheath includes a tapered portion protruding substantially longitudinally distally from a portion of the distal catheter face surface. A plurality of tubes extends through the lumen towards the distal catheter face surface. Each tube of the plurality of tubes is configured to selectively guide exposure of a radiation source to the target portion of the native tissue.
Abstract:
The smart HVAC manifold system for servicing air conditioning systems is designed to dynamically manage the data acquisition process and to measure and calculate the performance indicators and output as the load conditions and or equipment operation change taking into account variables in the installation that can impact performance. Both visually and by a very specific data set the performance of the equipment and the installation can quickly be assessed and specific problems identified along with suggestions of typical faults or problems that may need addressed by the technician.
Abstract:
One aspect of the present disclosure relates to a treatment probe comprising an elongated body member and a needle portion. The elongated body member can have a proximal end portion and a distal end portion. The needle portion can be connected to the distal end portion. The needle portion can include at least one electrode and at least one fluid port. The at least one electrode and the at least one fluid port can be configured to deliver electrical energy and a tumescent fluid, respectively, so that superficial tissue planes overlying a target nerve are protected from inadvertent heat damage as a result of application of electrical energy to a target nerve.
Abstract:
One aspect of the present disclosure is a smart patient monitoring system. A sensor is coupled to a patient and configured to detect biometric data associated with the patient. A mobile computing device includes a memory that stores computer-executable instructions and a processor executes the computer-executable instructions. The mobile computing device receives the biometric data from the sensor; processes the biometric data to monitor a health status of the patient; and provides therapeutic feedback related to the health status.
Abstract:
An apparatus for targeting a desired target site on a body tissue comprising a wall of a first body cavity of a patient includes a target catheter. The framing member, when deployed into an expanded condition, has a framing member body which includes a three-dimensionally bulbous portion defining a maximum body footprint in a lateral dimension and has longitudinally spaced proximal and distal body ends which are both longitudinally spaced from the maximum body footprint. The proximal body end is attached to the target catheter. A protrusion has a diameter which is smaller than the maximum body footprint diameter. At least one target point is carried by the framing member and is adapted for placement adjacent the desired target site. At least one target pathway is attached to at least one target point. At least a portion of the target pathway is substantially spaced apart from the framing member body.
Abstract:
One aspect of the present disclosure relates to a reversible airway device that includes a tubular guide, a laryngeal mask, an endotracheal tube, and a sealing mechanism. The tubular guide can have a distal end portion, a proximal end portion, and a first passageway extending between the distal and proximal end portions. The laryngeal mask can be attached to the distal end portion of the tubular guide. The laryngeal mask can include an opening in fluid communication with the first passageway. The endotracheal tube can be slidably disposed within the first passageway and have a second passageway that is concentric with the first passageway. The sealing mechanism can be disposed within the first passageway and be configured to occlude the flow of a gas through the first passageway.
Abstract:
A closed-loop therapy delivery system for modulating uterine function in a mammal can include: at least one electrode configured to deliver an electric current to a spinal cord target associated with uterine function; a power source in electrical communication with the at least one electrode; at least one sensor in electrical communication with the at least one electrode; and a controller in electrical communication with each of the at least one electrode and the at least one sensor. The controller can be configured to automatically coordinate operation of the power source. The controller can be configured to direct delivery of the electric current to the at least one electrode to deliver a therapy signal to the spinal cord target in an amount and for a time sufficient to effect a change in sympathetic and/or parasympathetic activity in the mammal and thereby modulate uterine function.
Abstract:
A method of providing a soft-tissue transplant to a receiving bone includes providing a transplant graft, comprising an elongated soft tissue, having first and second soft tissue ends longitudinally separated by a soft tissue body, and a bone block directly connected with the first soft tissue end. The bone block and soft tissue have been integrally formed as a unitary whole. An anchor cavity is machined in the receiving bone. The anchor cavity is shaped to substantially accept the bone block in a mating relationship. A majority of a volume of the bone block is placed in the anchor cavity. The bone block is fastened within the anchor cavity.
Abstract:
Systems and methods are provided for generating a model relating parameters generated via a first molecular imaging modality to parameters generated via a second molecular imaging modality. First and second feature extractors extract, from images of a region of interest obtained via respective first and second molecular imaging modalities, respective sets of parameters for respective first and second sets of locations. A mapping component associates respective locations of the first and second sets of locations according to their spatial relationship within the region of interest to produce a training set. Each example in the training set comprises a set of parameters associated with a location in the first set of locations and a set of parameters associated with a location in the second set. A modeling component generates a predictive model relating the parameters associated with the first modality with at least one parameter associated with the second modality.
