摘要: Parameters for cardiac ablation can be determined using a map of one or more biological properties of a tissue to be ablated, such as tissue thickness. The biological properties are used to compute a transmurality index map. In turn, the transmurality index map can be used to determine one or more of ablation energy level, ablation time, and ablation contact force to achieve a transmural lesion. Graphical representations of the biological property maps, the transmural index map, and/or the ablation parameters can be output, for example on geometric models of the heart and/or the ablation catheter.

摘要: An ultrapolar electrosurgery blade includes lop and bottom thin elongated conductive members in vertical, alignment and spaced apart, from one another along their lengths, a non-conductive coating covering both the top and bottom thin elongated conductive members and the space located between them to create opposing non-conductive sides of the blade with conductive cutting and ends and conductive non-cutting ends exposed, and both return and active contact layers located on each of the opposing non-conductive sides of the blade. An ultrapolar electrosurgery blade assembly having argon beam capability further includes a non-conductive tube member having a slot positioned over the top of the ultrapolar electrosurgery blade and a conductive hollow tubular member contained within at least a portion of the non-conductive tube member.

摘要: A catheter treatment apparatus comprises an elongate tubular member and an expandable support. The expandable support comprises a radioactive substance to treat cancerous tissue and is configured to expand from a narrow profile for insertion to a wide profile to engage and treat tissue remaining after resection. The expandable support can be sized to fit within a volume of removed tissue to place the radioactive substance in proximity to the capsule and remaining tissue, to spare the capsule and proximate nerves and vessels to treat tissue in proximity to the capsule. The elongate tubular member may comprise a channel such as a lumen to pass a bodily fluid such as urine when the expandable support engages the tissue to treat the patient for a plurality of days. The treatment apparatus can be used to resect and diagnose tissue concurrently. Based on the diagnosis, targeted segmental treatment may be given.

摘要: Systems and methods for treating a patient's mucus hypersecretion condition are disclosed herein. Certain implementations may involve a method for reducing mucus secretion in an upper airway of a patient to treat at least one of post nasal drip or chronic cough. The method may include advancing a treatment delivery portion of an energy-based treatment device into a nostril of the patient. The treatment delivery portion may contact mucosal tissue of the upper airway without piercing the mucosal tissue. The treatment delivery portion may deliver treatment to at least one tissue selected from the group of the mucosal tissue and another tissue underlying the mucosal tissue to modify a property of the at least one tissue and thus treat at least one of post nasal drip or chronic cough in the patient.

摘要: Systems and methods deploy a therapeutic or diagnostic element into contact with a body tissue region. The systems and methods can sense position of the therapeutic or diagnostic element relative to a targeted tissue region without direct or indirect visualization, by sensing fluid pressure in a fluid path having an outlet located at or near the therapeutic or diagnostic element. The systems and methods can also inflate the therapeutic or diagnostic element during use, while taking steps to avoid over-inflation and/or while dynamically monitoring the pressure conditions within the expanded element.

摘要: An instrument test arrangement is specified, which is preferably equipped for medical instruments for argon plasma coagulation. The instrument test arrangement comprises an electrode arrangement, comprising at least one test electrode. In a preferred embodiment, a test electrode is thereby connected to two neutral conductors of a neutral conductor cable or device, wherein the neutral conductors are insulated from one another, and wherein the first coupling impedance between the test electrode and the first neutral conductor and the second coupling impedance between the test electrode and the second neutral conductor are equal or at most slightly different, so that a split circuit, which is assigned to a neutral electrode arrangement, does not trigger due to the strike of a test spark or arc.
