A tissue detection system includes a probe having a body and an emission optical fiber extending from an input end through the probe body to an output end at a distal end portion of the probe body. The emission optical fiber defines a Numerical Aperture (NA). The tissue detection system further includes an emitter configured to output electromagnetic radiation and an optical coupler optically coupling the emitter with the input end of the emission optical fiber such that, in response to receiving the output from the emitter, electromagnetic radiation is input to the input end of the emission optical fiber. The optical coupler modifies the electromagnetic radiation such that the electromagnetic radiation input to the input end of the emission optical fiber defines an NA about equal to or less than the NA of the emission optical fiber.

A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

A device for performing minimally invasive repair of mitral valve leaflets in a beating heart through the delivery and implantation of artificial chordae tendineae includes a handle for positioning the device into a chest cavity of the patient, a capture assembly adapted to capture a valve leaflet between distal an proximal tip portions, a needle adapted to penetrate the valve leaflet, and a capture confirmation system for verifying capture of the valve leaflet between the distal and proximal tip potions.

Devices, systems, and methods perform optical-scanning operations to acquire fluorescence data values corresponding to fluorescence data collected from inside a bodily lumen. A processor receives the fluorescence data; calculates a threshold background fluorescence value based on a central tendency of at least part of the fluorescence data values; discards fluorescence data values that are lower than the threshold background fluorescence value, thereby creating corrected fluorescence data values; and generates an image of the bodily lumen based on the corrected fluorescence data values.

Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.

A surgical drain for monitoring an internal site in a patient. The surgical drain can include an outer flexible tube, a first tube, and a second tube. The outer flexible tube can include a plurality of ports extending from a proximal end to a distal patient end. The first tube can be inserted within the first port, having at least one lumen side extending therethrough in fluid communication with a collection device. The first tube is configured to drain fluid from an internal site in the patient to the collection device. The second tube can extend through a second port having a camera at the distal patient end of the second tube.

A system for using robotic telesurgery to implant a smart implant is disclosed. The system comprises a remote doctor module communicatively coupled with an operating room module over a cloud network. The operating room module comprises a robotic arm, a processor, and communication interface which communicates with the smart implant during the surgical procedure. The Operating Room Module testing the smart implant prior to implantation surgery; correlating data collected during the implantation surgery against past data from previous surgeries; determining whether the plurality of sensors is working properly; and transferring communication with the smart implant to a user device receive and monitor data from the plurality of sensors integrated into the smart implant to determine the smart implant is operating according as expected and to monitor the patient's condition.

Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.

A robotic system includes a manipulator assembly including at least one actuator, a control system including at least one processor configured to control the manipulator assembly, an elongate flexible catheter configured to be manipulated by the at least one actuator, and a support structure mounted on a proximal portion of the elongate flexible catheter. The support structure includes a first alignment feature and a second alignment feature. The first alignment feature is configured to mate with a first sensor such that the first sensor is maintained parallel to a longitudinal axis of the support structure. The second alignment feature is configured to mate with a second sensor such that the second sensor is maintained parallel to the longitudinal axis of the support structure and such that the second sensor is fixed relative to the first sensor in at least one degree of freedom.

A catheter system comprises an elongate catheter body including a distal end, a cannulation lumen extending through the catheter body and terminating at the distal end of the catheter body, and a steering element extending through the catheter body for steering the distal end. The catheter system also comprises an imaging element secured to a distal end portion of the catheter body and configured to obtain optical images of an area located distally of the distal end of the catheter body. The catheter body includes a ridge extending axially along an outer surface of the distal end portion, wherein a width of the ridge measured about a circumference of the catheter body is less than a length of the ridge measured along the longitudinal axis, and the imaging element is radially aligned with the ridge with at least a portion of the imaging element disposed within the ridge.
