A prolapse prevention device formed by a continuous wire-like structure having a first end and a second end disconnected from each other. The continuous wire-like structure is substantially straight in a delivery configuration. The prolapse prevention device in a deployed configuration includes a centering ring of the continuous wire-like structure configured to seat adjacent to and upstream of an annulus of a heart valve in situ, a vertical support of the continuous wire-like structure which extends from the centering ring and includes an apex configured to seat against a roof of an atrium in situ, and a leaflet backstop of the continuous wire-like structure extending radially inward from the centering ring and configured to contact at least at least a first leaflet of the heart valve in situ to exert a pressure in a downstream direction on the first leaflet to prevent the first leaflet from prolapsing into the atrium.

Prolapse prevention device and methods of use thereof

A system for performing a surgical procedure includes a controller including a memory and a processor, the memory storing instructions, which when executed by the processor cause the processor to receive an image captured by a camera, generate a segmented image by applying a first threshold value to the image captured by the camera, identify a lumen within the segmented image, determine a centroid of the lumen within the segmented image, and align a portion of a surgical device operably coupled to the controller with the centroid of the lumen.

Autonomous endobronchial access with an EM guided catheter

A disposable cleaning unit is described herein including an inner receptacle and an outer receptacle.

Disposable cleaning units for a reusable medical device

A method and system of detecting a position and orientation of the catheter in five degrees of freedom (5DOF) in a first position and in a second position and calculating a sixth degree of freedom of the catheter based on a difference in the detected 5DOF position and orientation of the catheter in the first position and the detected 5DOF position and orientation in the second position.

Six degrees of freedom from a single inductive pickup coil sensor

A system and method for a catheter in a luminal network including capturing images via an optical sensor, comparing the captured images to pre-operative images, identifying fiducials in the captured images that correspond to fiducials in the pre-operative images; and depicting the position of the catheter in a three-dimensional (3D) model or two-dimensional (2D) images derived from the pre-operative images.

Surgical tool navigation using sensor fusion

A flexible catheter includes an elongated body, a first monolithic wire, and a second monolithic wire. The first monolithic wire forms a first sensor that is disposed in the distal end portion of the elongated body. The first sensor is configured to detect the position of a distal end of the elongated body within anatomy of a patient. The second monolithic wire forms a second sensor that is disposed in the distal end portion of the elongated body a known distance from the first sensor. The first and second sensors are configured to determine the position of the distal end portion within six degrees-of-freedom. A method of manufacturing the flexible catheter is also provided.

Method of manufacturing an elongated catheter having multiple sensors for three-dimensional location of the catheter

A prolapse prevention device formed by a continuous wire-like structure having a first end and a second end disconnected from each other. The continuous wire-like structure of the prolapse prevention device is substantially straight in a delivery configuration. The prolapse prevention device in a deployed configuration includes a centering ring of the continuous wire-like structure configured to seat adjacent to and upstream of an annulus of a heart valve in situ, a vertical support of the continuous wire-like structure which extends from the centering ring and includes an apex configured to seat against a roof of an atrium in situ, and a leaflet backstop of the continuous wire-like structure extending radially inward from the centering ring and configured to contact at least at least a first leaflet of the heart valve in situ to exert a pressure in a downstream direction on the first leaflet to prevent the first leaflet from prolapsing into the atrium.

A method of manufacturing a flexible catheter with a locatable sensor includes non-rotatably coupling a spool with a wire to a first portion of a spool carrier, non-rotatably coupling the spool carrier to a catheter body, and rotating the spool carrier with the catheter body, thereby wrapping a portion of the wire about a distal end portion of the catheter body to form a wrapping layer.

Methods of manufacturing a catheter having a sensor

A method of manufacturing a flexible catheter with a locatable sensor includes simultaneously rotating first and second spools about a common axis, whereby first and second leads of a wire twist together to form a twisted pair of the wire, and rotating a catheter body about a longitudinal axis defined by the catheter body, whereby the twisted pair of the wire wraps about a proximal end portion of the catheter body.

An additive manufacturing system includes a gantry configured to move in a build plane. A platen is configured to support a part being built in a layer by layer process and wherein the platen is configured to move in a direction substantially normal to the build plane. A head carriage is carried by the gantry wherein the head carriage includes ferromagnetic material. The system includes at least one print head where the print head includes a housing and one or more magnets attached to the housing wherein the at least one print head is configured to be coupled to the head carriage through a magnetic coupling between the one or more magnets and the ferromagnetic material such that the print head is configured to move rotationally relative to the head carriage.
