摘要： Catheters for ablation and removal of occlusions from blood vessels are provided. Laser cutting systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Catheters include expandable distal ends to facilitate, in some cases, relatively high bodily material removal rates compared to other devices.

摘要： A laser ablation catheter includes a distal tip, and the distal tip includes a body that defines a longitudinal axis. A first orientation indicator is formed on the body, and a second orientation indicator is formed on the body. The second orientation indicator is disposed relative to the first orientation indicator such that when the distal tip is viewed in a first side view, the second orientation indicator and the first orientation indicator overlap and visually contrast with the body. A third orientation indicator is formed on the body, and the third orientation indicator disposed relative to the second orientation indicator such that when the distal tip is viewed in a second side view, the third orientation indicator and the second orientation indicator overlap and visually contrast with the body. The second side view and the first side view are substantially 90 degrees apart about the longitudinal axis.

摘要： A laser ablation catheter includes a distal tip, and the distal tip includes a body that defines a longitudinal axis. A first orientation indicator is formed on the body, and the first orientation indicator has an alphanumeric shape. A second orientation indicator is formed on the body. The second orientation indicator is disposed relative to the first orientation indicator such that when the distal tip is viewed in a first side view, the second orientation indicator and the first orientation indicator overlap, appear as the alphanumeric shape, and visually contrast with the body. The second orientation indicator is configured such that when the distal tip is viewed in a second side view, the second orientation indicator appears as the alphanumeric shape and visually contrasts with the body, the second side view and the first side view being substantially 90 degrees apart about the longitudinal axis.

摘要： A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the surface of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with an amphiphilic polymer coating comprising a therapeutic agent and an amphiphilic polymer or co-polymer. The medical disposable device is inserted into a body lumen, and expanded to contact the amphiphilic polymer coating against the body lumen. The total solubility of the polymer or co-polymer in vivo prevents any embolic hazard associated with the amphiphilic polymer coating.

摘要： The present disclosure relates to a system and method for coordinated laser delivery and imaging during an interventional procedure. A method may include activating an imaging source to provide a pulsed imaging signal and activating a laser source to provide a pulsed laser signal while the imaging source remains activated. The method may include coordinating the pulsed laser signal and the pulsed imaging signal to output each pulse of the pulsed laser signal and each pulse of the pulsed imaging signal in non-overlapping time windows. A system may include a controller in communication with the laser source and the imaging source for coordinating the output of the laser signal and the imaging signal.

摘要： A system can include a microprocessor executable controller configured, based on one or more of total fiber active area of a laser catheter, imaging information regarding the target and/or non-target endovascular structure(s), target endovascular structure characterization information, current location and/or orientation of a distal tip of the laser catheter, and area of contact of the distal tip with the target and/or non-target endovascular structure to select at least one of a fiber active area for each optical channel, a number of optical channels, a configuration of fibers in an optical channel, an optical channel to be irradiated, and an ordering of optical channel irradiation.

摘要： This disclosure discusses various methods and devices for providing multiple types of indicators to be used with a sheath set. One type of indicator indicates the linear position and alignment of each of the sheaths within the sheath set, and another type of indicator indicates the rotational position and alignment of the sheaths. Both types of indicators may be included on the ends of the sheath set proximal to the user outside the patient's vasculature, thereby informing the user of the sheath set of the linear and rotational position and alignment of the ends of the inner and outer sheaths within the vasculature.

摘要： A device for extending a lead according to some embodiments includes a body, a tubular member coupled to the body, the tubular member comprising an outer surface, wherein the outer surface is sized to insert into an inner lumen of a lead, the tubular member is movable between a first configuration in which the tubular member slides into the lead, and a second configuration in which at least a portion of the tubular member expands to engage an inner surface of the lead; and, an actuation mechanism operatively coupled to the tubular member, the actuation mechanism configured to move the tubular member between the first configuration and second configuration.

摘要： A method for detaching an object from a patient includes providing a tool having a sheath, and a separating assembly operably coupled to a distal end of the sheath. The separating assembly includes a separator moveably coupled to a tip via a threadable connection. The separating assembly is placed near patient tissue that is attached to the object, the sheath is rotated to move the separator distal to the tip, and the separator is applied to the patient tissue that is attached to the object, so as to separate the tissue. A separating system includes a sheath, and a separator threadably coupled with a distal end of the sheath. The separator is adapted to switch between a first configuration where a separating mechanism is deployed, and a second configuration where the separating mechanism is undeployed.

摘要： Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting device is configured to engage patient formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting device is caused to move further into the engaged tissue and slit the tissue past the point of engagement. The slitting device causes the tissue to separate along an axial direction of the length of the formed tissue and releases at least some of the force containing the object. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.
