Patent number: 8864761Abstract: A system for determining proximity of a surgical device relative to an anatomical structure includes at least one surgical device having a sensor assembly operably coupled to a processing unit. The sensor assembly is configured to transmit at least one electrical signal through the target anatomical structure to elicit a measurable response from the target anatomical structure. The processing unit is configured to calculate a signature property value of the target anatomical structure based on the measurable response and to determine proximity of the at least one surgical device relative to the target anatomical structure based on a comparison between the signature property value and at least one other signature property. An indicator is operably coupled to the processing unit and is configured to alert a user of the identified target anatomical structure based on the determined proximity.Type: GrantFiled: March 10, 2010Date of Patent: October 21, 2014Assignee: Covidien LPInventors: Kristin D. Johnson, Christopher A. Valentine, Scott F. Alexander, Ronald J. Podhajsky

Patent number: 8834462Abstract: A medical device for treating and analyzing tissue is disclosed. The device includes a plasma applicator having a housing. The housing includes a substantially tubular shape and defining a lumen therethrough. The lumen is in fluid communication with an ionizable media source configured to supply ionizable media thereto. The applicator also includes one or more electrodes coupled to the housing. The electrodes are adapted to couple to a power source configured to that energizes electrodes to ignite the ionizable media to form a plasma plume for treating tissue. The device also includes an effluent-collection attachment coupled to the plasma applicator, the effluent-collection attachment configured to collect at least a portion of a plasma effluent.Type: GrantFiled: June 1, 2010Date of Patent: September 16, 2014Assignee: Covidien LPInventors: Kristin D. Johnson, Kyle R. Rick, Christopher A. Valentine, Mika N. Sinanan

Publication number: 20120253339Abstract: A radio frequency-based surgical implant fixation apparatus is provided and includes a housing and a shaft that is operably coupled to housing. A longitudinal axis is defined through the shaft. The housing is adapted to connect to a source of electrosurgical energy. An approximator assembly has an elongated rod that is coaxially coupled to the shaft and is configured to reciprocate therethrough from an extended position to a retracted position. A plurality of delivery arms is operably coupled to a distal end of the elongated rod. The delivery arms are configured to releasably receive a portion of a surgical implant and selectively connect to the energy source to transmit electrosurgical energy to the surgical implant to fuse the surgical implant to tissue upon actuation thereof.Type: ApplicationFiled: February 7, 2012Publication date: October 4, 2012Inventors: Kyle Rick, Christopher A.
