Publication number: 20120010613Abstract: A method and apparatus include determining a value of a parameter associated with operation of an electrosurgical probe having a particular probe design, and determining whether the value of the parameter is within a range of values that has been predetermined for the particular probe design to indicate that the probe is treating tissue in a desired manner. Power is delivered to the probe according to an algorithm based upon a determination that the value of the parameter is outside the range of values The algorithm delivers power in a pulsed profile including portions of low power and portions of high power. In one embodiment, the tissue treatment is ablation, the parameter is impedance, and the method limits tissue necrosis to less than 200 microns. In another embodiment, the tissue treatment is shrinkage, the parameter is temperature, and the method limits power delivery when the probe is not shrinking tissue.Type: ApplicationFiled: September 23, 2011Publication date: January 12, 2012Applicant: SMITH & NEPHEW, INC.Inventors: Douglas M. Lorang, Mathew E. Mitchell, Karen Drucker, Kobi Iki

Publication number: 20110230879Abstract: An electrosurgical instrument for ablating cartilage while limiting collateral damage includes a non-conducting head with a small electrically conductive surface. The head of the instrument is coupled to a shaft by a flexible portion. The flexible portion biases the electrically conductive surface towards a tissue surface. The head is pivotably coupled to the shaft such that the electrically conductive surface is oriented substantially parallel to the tissue surface as the head slides across the tissue surface. A method of performing electrosurgery includes positioning the electrically conductive surface adjacent to the tissue surface, and sliding the shaft across the tissue surface with the head pivoting such that the electrically conductive surface is oriented substantially parallel to the tissue surface.Type: ApplicationFiled: May 27, 2011Publication date: September 22, 2011Applicant: SMITH & NEPHEW, INC.Inventors: Kobi Iki, William M.

Publication number: 20090118777Abstract: Methods and devices providing for bilateral stimulation of left and right splanchnic nerves. Some embodiments of the method increase satiety, reduce appetite, affect gastric motility, and/or reduce food intake, resulting in weight loss. Some methods provided take advantage of anatomy, physiology, and natural body time periods to change stimulation locations and patterns to prevent the body from ignoring the administered stimulation signals in order to continue to induce weight loss over long time periods.Type: ApplicationFiled: August 2, 2008Publication date: May 7, 2009Inventors: Kobi IKI, John D.

Publication number: 20060246210Abstract: A stent, having openings, is mounted onto a mandrel. An agent-containing film is applied onto the stent and the two are pressed against one another so that at least a portion of the film is pressed at least partially into the openings. The film is adhered to the stent. Any excess film is removed to create a stent/film combination which is removed from the mandrel and enclosed within a sleeve of porous material to create a covered agent-eluting stent.Type: ApplicationFiled: April 29, 2005Publication date: November 2, 2006Applicant: VASCULAR ARCHITECTS INC., a Delaware CorporationInventors: Kobi Iki, Marshall Tsuruda, Teodoro Tecson, Angelica Alvarado, Jasbir Badesha

Patent number: 7063720Abstract: A covered stent includes a generally tubular stent body having inner and outer stent body surfaces. A sleeve of porous material encloses the stent body and has inner and outer portions opposed to the inner and outer stent body surfaces. A therapeutic agent is located along the stent body, the agent being diffusible through the material. A diffusion barrier is located between the inner material portion and the agent along the stent. The diffusion barrier prevents passage of at least a significant amount the agent through the inner portion of the sleeve of porous material. A diffusion restrictor is located between the outer portion of the sleeve of porous material and the agent along the stent. The diffusion restrictor permits passage of the agent through the inner material portion at a therapeutic level.Type: GrantFiled: September 14, 2004Date of Patent: June 20, 2006Assignee: The Wallace Enterprises, Inc.Inventors: Kobi Iki, Marshall Tsuruda

Patent number: 6757565Abstract: An electrosurgical instrument is provided, having a holding formation, an elongated probe, an electrode, and a conductor. The elongated probe is connected to and extends from the holding formation. The electrode is located on an end of the elongated probe opposing the holding formation, and has a leading edge and a face. The electrode is locatable so that the face is substantially in a horizontal plane and the leading edge is above the horizontal plane. The conductor extends along the elongated probe and has a portion connected to the electrode to provide RF power thereto. The electrode creates a temperature profile with a temperature adjacent to the leading edge being higher than a temperature adjacent to the face.Type: GrantFiled: February 8, 2002Date of Patent: June 29, 2004Assignee: Oratec Interventions, Inc.Inventors: Hugh R.
