Title: Rf ablation apparatus and method having electrode/tissue contact assessment scheme and electrocardiogram filtering
Inventor: CASTELLANO THOMAS M
IPC: A61B5/296
Filed: 2000-06-15
Abstract: A method of assessing the adequacy of contact between an ablation electrode and biological tissue within a biological organ having biological fluid therein includes the steps of positioning the ablation electrode proximal th e biological tissue; positioning a reference electrode a distance from the ablation electrode; measuring the impedance between the ablation electrode a nd the reference electrode at a first frequency and measuring the impedance between the ablation electrode and the reference electrode at a second frequency. The percentage difference between the first-frequency impedance a nd the second-frequency impedance provides an indication of the state of electrode/tissue contact. In general, a percentage difference of at least approximately 10 % serves as an indication of substantially complete electrode/tissue contact. A percentage difference in the approximate range between 5 % and 10 % serves as an indication of partial electrode/tissue contact. A percentage difference less than approximately 5 % serves as an indication of no electrode/tissue contact. Ratiometric measurements may also  be used to assess the state of electrode/tissue contact.

Title: Methods and apparatus for measuring valve annuluses during heart valve-replacement surgery
Inventor: RHEE RICHARD
IPC: A61B5/107
Filed: 2000-09-13
Abstract: A sizer measures a valve annulus to determine a size of an artificial heart valve to be sewn in the valve annulus during heart-valve replacement surgery. The sizer includes a support member and a resilient member. The support member has a size corresponding to the size of one of a plurality of artificial heart valves. The resilient member is disposed about the support member and has a resiliency substantially equal to the resiliency of a sewing ring of the artificial heart valve. Accordingly, when a surgeon inserts the sizer into a valve annulus, the resilient member conforms to the shape of the valve annulus much like the sewing ring will conform when positioned in the annulus and sewn in place. The surgeon is therefore able to determine more accurately the size of the annulus and, thereafter, to select a properly sized artificial valve.

Title: Cover for electromagnetic treatment applicator
Inventor: GEORGE FRANK R
IPC: H05K9/00
Filed: 2000-09-14
Abstract: A disposable cover for electromagnetic treatment applicators prevents undesired exposure to potentially harmful radiation. The cover is a pouch-li ke structure having a back surface (which faces opposite, or away from, the treatment area) constructed from shielding material, such as metallized polyethylene. At least a portion of the cover which faces the treatment area  is constructed solely from non-shielding material. Securing means, such as adhesive strips, ZIP-LOCK.RTM., or other interlocking edges, secure the applicator inside the cover and close off any leaks. The electromagnetic properties of the cover are integrated into the circuitry for the treatment applicator, such that the applicator is not functional in the absence of the  cover. In use, an electromagnetic treatment applicator is inserted into the cover and positioned over the area to be treated, with the non-shielding, or  "window", portion of the cover overlying the treatment area. Once assembled,  the applicator/cover combination forms a closely matched and tuned network f or effecting a highly efficient RF output. When activated, the generated electromagnetic energy only exits the cover through the opening or "window",  thereby preventing exposure of the patient or caregiver to potentially harmf ul radiation.
