摘要:
A catheter and catheter system for eccentric remodeling and/or removal of atherosclerotic material of a blood vessel of a patient include an elongate flexible catheter body with a radially expandable structure. A plurality of electrodes or other electrosurgical energy delivery surfaces can radially engage atherosclerotic material when the structure expands. An atherosclerotic material detector near the distal end of the catheter body may measure circumferential atherosclerotic material distribution, and a power source selectively energizes the electrodes to eccentrically remodel the measured atherosclerotic material.
摘要:
Devices, systems, and methods for treating atherosclerotic lesions and other disease states, particularly for treatment of vulnerable plaques, can incorporate optical coherence tomography or other imaging techniques which allow a structure and location of an eccentric plaque to be characterized. Remodeling and/or ablative laser energy can then be selectively and automatically directed to the appropriate plaque structures, often without imposing mechanical trauma to the entire circumference of the lumen wall.
摘要:
A catheter and catheter system can use energy tailored for remodeling and/or removal of target material along a body lumen, often of atherosclerotic material of a blood vessel of a patient. An elongate flexible catheter body with a radially expandable structure may have a plurality of electrodes or other electrosurgical energy delivery surfaces to radially engage atherosclerotic material when the structure expands. An atherosclerotic material detector system may measure and/or characterize the atherosclerotic material and its location, optionally using impedance monitoring.
摘要:
The invention provides apparatus and methods for cleaning an ear canal. The ear cleaning apparatus includes an elongated support member having an outer surface and first and second ends, and a bristle member that is attached to one end of the support member. The bristle member includes a plurality of flexible elongated members that are configured to contact a surface of an ear canal when the support member/bristle member assembly is inserted into the ear canal.
摘要:
A securing mechanism comprising a plurality of outwardly projecting members having a plurality of contact points that are configured to contact a surface of an opening when disposed on a space access device that is inserted in the opening, the securing mechanism being configured to apply a pressure to a contact surface within the opening less than approximately 10000 kPa.
摘要:
An apparatus for insertion, positioning and removal of an in-ear-canal hearing aid, comprising a resilient handle, an elongated support member configured to fit into an ear canal, the support member having a first end that is configured to engage the handle and a second end that includes hearing aid engagement means configured to removably engage an in-ear-canal hearing aid, and an ear canal ingression stop that is configured to limit travel of the support member and, thereby, the in-ear-canal hearing aid when engaged thereto in the ear canal.
摘要:
The present invention encompasses a heat exchange catheter for indirect cooling of internal organs, particularly the heart. The heat exchange catheter is inserted into the esophagus and a cooled fluid is circulated within the catheter, cooling the esophagus, and by conduction, the heart. The heat exchange catheter or the invention may be rapidly deployed in the field and is particularly useful for preventing and reducing tissue damage caused by ischemia.
摘要:
Apparatus, systems and methods for reducing feedback in a hearing aid that includes a transducer configured to detect sound, a sound processor configured to process signals from the transducer, a receiver configured to receive signals outputted from the sound processor, and an acoustic feedback reduction system. The acoustic feedback reduction system is configured to provide signals to the sound processor to produce a null targeting signal steerable toward a source of feedback.
摘要:
An apparatus for insertion, positioning and removal of an in-ear-canal hearing aid, comprising a resilient handle, an elongated support member configured to fit into an ear canal, the support member having a first end that is configured to engage the handle and a second end that includes magnetic engagement means configured to removably engage an in-ear-canal hearing aid, and an ear canal ingression stop that is configured to limit travel of the support member and, thereby, the in-ear-canal hearing aid when engaged thereto in the ear canal.
