    摘要: An example system for sensing catheter contact is disclosed. The system includes an elongate tubular member, a tip member and a flexible support structure including a support member. A proximal portion of the support structure may be coupled to the distal end of the tubular member while a distal portion may be coupled to the proximal end of the tip member. The system may also include an electroactive polymer member disposed along the support member, wherein displacement of the support member activates the electroactive polymer member such that an electrical response is output from the electroactive polymer member. A processor, electrically coupled to the electroactive polymer member, may be configured to evaluate the electrical response from the electroactive polymer member to determine a contact force of the tip member with tissue.

    摘要: This disclosure describes an implantable medical electrical lead and an ICD system utilizing the lead. The lead includes a lead body defining a proximal end and a distal portion, wherein at least a part of the distal portion of the lead body defines an undulating configuration. The lead includes a defibrillation electrode that includes a plurality of defibrillation electrode segments disposed along the undulating configuration spaced apart from one another by a distance. The lead also includes at least one electrode disposed between adjacent sections of the plurality of defibrillation sections. The at least one electrode is configured to deliver a pacing pulse to the heart and/or sense cardiac electrical activity of the heart.

    摘要: In some embodiments, a plurality of transducers of a transducer-based device may be selected for activation. A first pair of subsets of the selected transducers may be identified for initial activation, each subset of the first pair being activated with a different phase angle range than the other. No transducer in one subset is sufficiently close to a transducer in the other subset to cause a confluence of ablated tissue regions therebetween. The first pair of subsets may be activated simultaneously or concurrently. Upon activation or a conclusion thereof of the pair of subsets of the selected transducers, one or more subsequent pairs of subsets of the selected transducers may be activated iteratively on a pair-by-pair basis, until all of the selected transducers have achieved desired activation results, according to some embodiments. Each subsequent pair may include the same or similar characteristics as the first pair.
