A medical instrument assembly including a handle assembly having a first handle portion and a second handle portion proximate the second end, wherein the second handle portion is slidably engaged with the first handle portion. A first localization element is attached to the first handle portion and a second localization element is attached to the second handle portion. A medical instrument is mechanically coupled to the second handle portion and a translation of the second handle portion with respect to the first handle portion causes a coincident and coextensive translation of the medical instrument. The amount of translation of the medical instrument is adapted to be determined by calculating the distance between the first localization element and the second localization element. The first and second localization elements may be electromagnetic sensors which positions may be determined by a navigation system.

Adjustable length medical instrument assembly with localization elements for tracking medical instrument extension

A medical device and its method of use includes a catheter, at least two electromagnetic sensing coils located within the distal tip of the catheter, and a multi-element planar ultrasound transducer array located within the distal tip of the catheter and configured to transmit and receive ultrasonic energy. The device also includes an imaging system coupled to the ultrasound transducer and is used for creating an image of tissue in a first target plane that extends orthogonally from the catheter body. The medical device also includes a backscatter evaluation system for use in receiving and evaluating the acoustic spectral characteristics of tissues within a second target area within the first target plane.

Endobronchial catheter system and method for rapid diagnosis of lung disease

A marking assembly includes a hollow cannula having a wall extending from a proximal end to a distal end. The wall defines a lumen of the cannula. The wall includes at least one opening at a distal portion of the cannula. A stylet is configured to be received in the lumen of the cannula. The stylet has a wall extending from a proximal end to a distal end. When the stylet is received in the lumen of the cannula, a circumferential space is defined between the wall of the stylet and the wall of the cannula such that fluid entering the circumferential space will exit the cannula through the at least one opening of the cannula.

Localization needle

A controller for use with a hollow endoscopic needle for collecting tissue, cell and/or fluid specimens from a patient that includes an outer body enclosing a slidably retaining a spring loaded plunger, a click and release plunger holder, a vacuum port, and a hollow needle attached to the plunger that is slidably retained in an outer tube or sheath. The controller permits a surgeon to positively control the needle and penetrate tissue, to pulse the needle, and to quickly and positively return the plunger and its needle back to its original un-pushed position. A vacuum or fluid pathway is defined between proximal and distal seals and along the needle's exterior and the interior of the outer tube or sheath and leads to a distal end of the hollow needle. A stylet can be slidably retained within the hollow needle, and can include a sensor to permit navigation.

Click and release endobronchial specimen collection histology needle

A method includes receiving during a first time interval associated with a path of motion of a dynamic body, image data associated with a plurality of images of the dynamic body. The plurality of images include an indication of a position of a first marker coupled to a garment at a first location, and a position of a second marker coupled to the garment at a second location. The garment is coupled to the dynamic body. During a second time interval, an image from the plurality of images is automatically identified that includes a position of the first marker that is substantially the same as a position of a first localization element relative to the dynamic body and a position of the second marker that is substantially the same as a position of the second localization element relative to the dynamic body.

Apparatus and method for image guided accuracy verification

A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric, perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

Systems, instruments, and methods for four dimensional soft tissue navigation

Apparatus and method for automatic image guided accuracy verification

An apparatus is provided for combined ergonomic support and situational sensory augmentation interface during an interactive session within a virtual environment generated by a computer system. The apparatus comprises a resilient body defining a mid portion extending laterally between a pair of side portions projecting transversely outward therefrom to terminate at respective free ends. The mid portion extends across a lap of a user. The mid and side portions collectively define an upper surface for hand and forearm support for the user and an inner side surface contoured about a cradle space for receiving a torso of the user in cradling manner. At least one actuator disposed on the resilient body is selectively driven in cooperation with the interactive session to generate tactile feedback to the user through at least one of the upper and inner side surfaces of the resilient body.

Ergonomic support apparatus having situational sensory augmentation

Generally, systems, methods, and apparatus related to the use of a dynamic imaging modality in an image guided intervention are disclosed herein. More specifically, the use of such modalities in sealing a bodily opening, such as those that may be formed during an invasive medical procedure are disclosed herein. In some embodiments, a method includes viewing a representation of an instrument within a body of a patient, adjusting a position of the instrument based on the viewing such that a portion of the instrument is at a location within the body of the patient, and delivering a sealant via the instrument to the location within the body of the patient. The sealant is configured to seal an opening in the body part.
