Shape-sensing systems and methods for catheters. The shape-sensing system can include a catheter, an optical interrogator, a console, and a display screen. The catheter can include an integrated optical-fiber stylet having fiber Bragg grating ('FBG') sensors along at least a distal-end portion thereof. The optical interrogator can be configured to send input optical signals into the optical-fiber stylet and receive FBG sensor-reflected optical signals therefrom. The console can be configured to convert the reflected optical signals into plottable data for displaying plots thereof on the display screen. The plots can include a plot of curvature vs. time for each FBG sensor of a selection of the FBG sensors in the distal-end portion of the optical-fiber stylet for identifying a distinctive change in strain of the optical-fiber stylet as a tip of the catheter is advanced into a superior vena cava of a patient.

Shape-sensing systems and methods for medical devices

A tether connector configured to form an electrical connection with a sensor connector through a sterile barrier disposed over the sensor connector. The tether connector can include a housing, an electrical lead extending from the housing, and a first piercing element in the housing orthogonally connected to the electrical lead, the first piercing element configured to pierce the sterile barrier to form the electrical connection with the sensor connector.

Connection systems and methods thereof for establishing an electrical connection through a drape

A connection system includes a first connector and a second connector configured for establishing one or more electrical connections through a drape. The first connector can include an alignment protrusion and a first piercing element having one or more electrical contacts configured to pierce the drape. The second connector can include an alignment notch, a channel, and a first receptacle configured to receive the first piercing element when inserted therein. The alignment notch can be configured to accept the alignment protrusion when the first connector is aligned with the second connector then disposed over the second connector. The channel can be configured to allow the alignment protrusion to slide along a length of the second connector. The first receptacle can have one or more electrical contacts configured to form at least a first electrical connection of the one or more electrical connections with the first connector.

Shape-sensing systems and methods for medical devices. The shape-sensing system can include a medical device, an optical interrogator, a console, and a display screen. The medical device can include an integrated optical-fiber stylet having fiber Bragg grating ('FBG') sensors along at least a distal-end portion thereof. The optical interrogator can be configured to send input optical signals into the optical-fiber stylet and receive FBG sensor-reflected optical signals therefrom. The console can be configured to convert the reflected optical signals with the aid of filtering algorithms of some optical signal-converter algorithms into plottable data for displaying plots thereof on the display screen. The plots can include a plot of curvature vs. time for each FBG sensor of a selection of the FBG sensors for identifying a distinctive change in strain of the optical-fiber stylet as a tip of the medical device is advanced into a superior vena cava of a patient.

Shape-sensing systems with filters and methods thereof

Connection systems and methods for establishing optical and electrical connections through a drape are disclosed. A connection system can include a plug and a receptacle, the plug being configured to insert into the receptacle with the drape therebetween. The plug can include an optical terminal extending from a plug housing and an electrical terminal extending from the plug housing. The electrical terminal can be configured as a piercing element for piercing the drape. The receptacle can include an optical receiver within a receptacle housing and an electrical receiver within the receptacle housing. The optical receiver can be configured to form the optical connection with the optical terminal, and the electrical receiver can be configured to form the electrical connection with the electrical terminal when the plug is inserted into the receptacle with the drape therebetween.

Optical-fiber connector modules are disclosed. In one example, an optical-fiber connector module can include a receptacle disposed in a housing, a cable extending from the housing, and an optical fiber within at least the cable. The receptacle can be configured to accept insertion of a first plug for establishing a first optical connection between the optical-fiber connector module and an optical-fiber stylet of a medical device. The cable can include a second plug for establishing a second optical connection between the optical-fiber connector module and an optical interrogator. The optical fiber extends from the receptacle through the cable to the second plug. The optical fiber can be configured to convey input optical signals from the optical interrogator to the optical-fiber stylet and reflected optical signals from the optical-fiber stylet to the optical interrogator. Shape-sensing systems including the optical-fiber connector modules and methods of the foregoing are also disclosed.

Optical-fiber connector modules including shape-sensing systems and methods thereof

A tracking system configured to track the movement of the medical device. The medical device can include a proximal portion that has a magnetic element attached thereto. The system can include a console with a display, and a TLS sensor. The TLS sensor can be disposed on a surface of the patient and can include an LED array. The LED array can indicate a proximity of the medical device to the TLS sensor. The LED array can provide different colors and/or project images to display information regarding the location, orientation, distance, or depth of the medical device. The display can be disposed on an upper surface of the TLS sensor and can be configured to show an image of the medical device disposed therebelow, along with additional information and imagery, thus providing a standalone unit.

Connection systems are disclosed for establishing one or more electrical connections through a drape. An example connection system includes a first connector and a second connector configured to connect to each other. The first connector includes a first-connector housing, an electrical lead extending from the first-connector housing, and at least a first piercing element within the first-connector housing configured to pierce the drape. The first piercing element is orthogonally connected to the electrical lead. The second connector includes a second-connector housing and at least a first receptacle within the second-connector housing. The first receptacle is configured to form at least a first electrical connection of the one or more electrical connections with the first piercing element when the first connector is disposed over the second connector with the drape therebetween. Methods are also disclosed herein for establishing one or more electrical connections through a drape with the connection systems.

Connection systems and methods thereof facilitate establishing electrical connections through a barrier such as a drape without compromising a sterile field established by the barrier. A connection system can include two connectors. A first connector can include a first-connector housing defining a cavity, a slideable end piece coupled to a distal-end portion of the first-connector housing, and at least a first piercing element connected to a first electrical lead. The first piercing element can be configured to enter the cavity and pierce a barrier disposed in the cavity when the slideable end piece is advanced toward a proximal-end portion of the first-connector housing. A second connector can include at least a first receptacle within a second-connector housing connected to a second electrical lead. The first receptacle can be configured to form at least a first electrical connection with the first piercing element after the first piercing element pierces the barrier.
