Publication number: 20120116367Abstract: A surgical instrument includes a handle assembly having a lower portion with a hingedly attached end piece. When open, the end piece allows for receipt of a data card in a lower portion aperture. When closed, the end piece covers the aperture. In another version, the aperture is configured to receive a data card and battery pack assembly. Information is readable from and to the data card to measure a number of minutes the instrument was used during a procedure. Such information is communicated via wired or wireless communication to another device to determine a payment for the number of minutes used. Minutes are buyable from the device and writable onto the data card prior to insertion of the card into the instrument. In another version, a testing sequence is used in saline or via a tissue proxy to test the functionality of an instrument prior to a procedure.Type: ApplicationFiled: October 19, 2011Publication date: May 10, 2012Inventors: Kevin L. Houser, Foster B. Stulen, Timothy G. Dietz, John W. Willis, Donna L. Korvick, Ashvani K. Madan, Aron O. Zingman

Publication number: 20120116263Abstract: A surgical instrument is separable into a transducer unit and a lower body portion. The lower body portion includes a waveguide and a casing. The transducer unit includes a transducer and a geared mechanism operable to couple the transducer to the waveguide. In some versions the geared mechanism includes bevel gears coupled to a rack and pinion such that linear motion may be used to rotatably couple a transducer to a waveguide. The rack gear may further include a handle extending out of the transducer unit casing to be actuatable by a user. The rack gear may also be flexible or rigid. In other versions, the bevel gears may be coupled to a threaded shaft that is operable to translate the transducer into the waveguide to form an interference fit. The transducer unit may also include a slide lock mechanism to couple to the casing of the lower body portion.Type: ApplicationFiled: October 17, 2011Publication date: May 10, 2012Inventors: Kevin L.

Publication number: 20120022525Abstract: In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise a pair of jaws, a closure beam, and a cutting member. The closure beam and the cutting member may be releasably coupled together by an interlocking member such that movement of the cutting member may cause the closure beam to also move relative to the jaws and cause the jaws to close and grip tissue, for example. The interlocking member may then unlock, allowing the cutting member to move through the gripped tissue and relative to the closure beam. Additionally, the cutting member and closure beam may be operated by a single trigger, which may be configured to provide haptic feedback to a user at various stages. Further, the jaws may be electrically energized to deliver energy and/or seal the gripped tissue.Type: ApplicationFiled: July 22, 2010Publication date: January 26, 2012Applicant: Ethicon Endo-Surgery, Inc.Inventors: Timothy G.

Publication number: 20110196404Abstract: In various embodiments, a surgical instrument for operation in an aqueous environment is provided. In at least one embodiment, the surgical instrument may include a hollow sheath and a blade disposed at least partially within the sheath. Coupled to the blade may be at least one ultrasonic transducer, which, in turn, may be coupled to a drive system. The drive system may be configured to deliver gross axial motions to the blade such that the blade translates with respect to the hollow sheath when the drive system is activated. Accordingly, tissue may be cut by the blade with gross axial movement of the blade and/or ultrasonic vibrational motion provided by the ultrasonic transducer(s). In alternative embodiments, the blade may be rotated axially instead of translated with respect to the hollow sheath.Type: ApplicationFiled: February 11, 2010Publication date: August 11, 2011Applicant: Ethicon Endo-Surgery, Inc.Inventors: Timothy G.

Publication number: 20110152901Abstract: A system includes an adjustable gastric band coupled with an injection port. The port includes sensors, a plate beneath a septum, and a vibration generator in communication with the sensors. A first sensor detects palpation through a patient's skin when the injection port is implanted in the patient. The vibration generator provides a vibratory response to detected palpation, thereby providing haptic feedback to a physician who is attempting to locate the injection port by palpating the patient. A second sensor detects a needle striking the plate, and the vibration generator provides a vibratory response to a detected needle strike. The vibration generator thereby provides haptic feedback to a physician to confirm that the needle has been successfully inserted through the septum. A pressure sensor may be used to provide vibratory feedback to the patient to indicate that an adjustment to the band is needed.Type: ApplicationFiled: December 17, 2009Publication date: June 23, 2011Inventors: Scott A. Woodruff, Amy L. Marcotte, Timothy G. Dietz

Patent number: 7959555Abstract: Various methods and devices for deploying a sub-pericardial sack about at least a portion of a heart to alleviate congestive heart failure. A medical device housing the sub-pericardial sack is inserted into the pericardial sack. An inverted umbrella framework is deployed through the medical device and into the pericardial sack to position the sub-pericardial sack adjacent the heart. The umbrella framework is then retracted through the medical device once the cardiac assist device is placed adjacent the heart. A steerable catheter can instead be deployed through the pericardial sack to deploy and position a cardiac assist device, such as a mesh, around the heart. The steerable catheter is covered by a sheath housing the cardiac assist device. Once the sheath is pulled back, the cardiac assist device is deployed and secured adjacent the heart. Filaments or tensions wires are used to tighten the mesh around the heart.Type: GrantFiled: October 13, 2009Date of Patent: June 14, 2011Assignee: Ethicon, Inc.Inventors: Timothy G. Dietz, Eugene L.
