Abstract:
One RFID equipped instrument includes an elongate body with a plurality of uniquely identified radio frequency identification chips spaced along the length of the elongate body. One system used for determining the position of an instrument includes an instrument; a plurality of radio frequency identification chips attached to the instrument; a reader connected to an antenna and adapted to communicate with each radio frequency identification chip using the antenna. One method for determining the position of an instrument using radio frequency identification chips includes providing a radio frequency identification chip reader and antenna; providing an instrument having a longitudinal axis and comprising a plurality of radio frequency identification chips placed along the longitudinal axis; moving the instrument relative to the antenna; and using information about a radio frequency identification chip detected by the antenna to determine the position of the instrument.
Abstract:
Waypoints for a steerable medical device are stored as the steerable medical device is moved within a patient. The stored waypoints are an ordered sequence of locations. The ordered sequence of locations defines a safe path within the patient for moving an articulatable portion of the steerable medical device. The articulatable portion of the steerable medical device is constrained to follow the safe path as the articulatable portion moves within the patient. For example, the articulatable portion of the steerable medical device is constrained to remain within a boundary region enclosing the safe path as the articulatable portion of the steerable medical device follows the safe path.
Abstract:
Apparatus and methods for endoscopic colectomy are described herein. A colectomy device having a first and a second tissue approximation device is mounted on a colonoscope separated from one another. During deployment of the colectomy device, a diseased portion of the colon is positioned inbetween the tissue approximation devices. The tissue approximation devices are radially expanded such that they contact and grasp the colon wall at two sites adjacent to the diseased portion of the colon. The diseased portion is separated from the omentum and is transected using a laparoscope or is drawn into the colonoscope for later removal. The tissue approximation devices are then urged towards one another over the colonoscope to approximate the two free edges of the colon into contact together where they are fastened to one another using the tissue approximation device as a surgical stapler to create an end-to-end anastomosis.
Abstract:
A system may comprise an instrument with an elongate body portion to be moved along a path, one or more datums, and a plurality of sense elements disposed at positions spaced along a length of the elongate body portion. Each sense element may sense or be sensed by one of the datums when in proximity to the datum. The system may also include a processor configured to compare signals transmitted from the datums or from the sense elements, including a first signal and a second signal, and identify, based on the comparison, a state of motion of the elongate body chosen from a state of motion in a forward direction (insertion) along a path and a state of motion in a rearward direction (withdrawal) along the path. The processor may identify the state of motion of the elongate body based on whether the first signal is lower than or higher than the second signal and whether the first and second signals are both increasing or decreasing.

Abstract:
A tunable ablation delivery device is disclosed. The tunable ablation delivery device includes a housing and a detection element on the housing for detecting a physiological indication. The tunable ablation delivery device further includes an ablation element disposed within the housing. An opening in the housing is positioned relative to the ablation element to facilitate a treatment using the ablation element modality.
Abstract:
A system for graphically visualizing an orientation of a steerable distal portion of an elongate instrument is disclosed. The system includes an instrument having an elongate body. The elongate body includes a proximal portion and a steerable distal portion. The system also includes at least one tensioning member attached to said steerable distal portion, wherein the actuation of said at least one tensioning member results in an approximate y-bend and an approximate x-bend of said steerable distal portion, and wherein said approximate y-bend and approximate x-bend define an approximate overall bend of said steerable distal portion. The system further includes a graphical user interface and an icon representing said approximate overall bend on said graphical user interface.

The tissue approximation devices are radially expanded such that they contact and grasp the colon wall at two sites adjacent to the diseased portion of the colon.

The tissue approximation devices are then urged towards one another over the colonoscope to approximate the two free edges of the colon into contact together where they are fastened to one another using the tissue approximation device as a surgical stapler to create an end-to-end anastomosis.
