摘要： A catheter system (200) for treating a treatment site (106) within or adjacent to a vessel wall (108A) or a heart valve, includes a light source (224), a balloon (104), a light guide (222A) and an optical analyzer assembly (242). The light source (224) generates first light energy (224B). The balloon (104) is positionable substantially adjacent to the treatment site (106). The balloon (104) has a balloon wall (130) that defines a balloon interior (146) that receives a balloon fluid (132). The light guide (222A) receives the first light energy (224B) and guides the first light energy (224B) in a first direction (121F) from a guide proximal end (222P) toward a guide distal end (222D) positioned within the balloon interior (146). The optical analyzer assembly (242) optically analyzes a second light energy (224C) from the light guide (222A) that moves in a second direction (121S) that is opposite the first direction. The optical analyzer assembly (242) includes a safety shutdown system (283) to inhibit the first light energy (224B) from being received by the guide proximal end (222P) of the light guide (222A).

摘要： A catheter system (100) for treating a vascular lesion (106 A) within or adjacent to a vessel wall (108 A) within a body (107) of a patient (109) includes a single light source (124) that generates light energy, a first light guide (122 A) and a second light guide (122A), and a multiplexer (128). The first light guide (122A) and the second light guide (122A) are each configured to selectively receive light energy from the light source (124). The multiplexer (128) receives the light energy from the light source (124) in the form of a source beam (124 A) and selectively directs the light energy from the light source (124) in the form of individual guide beams (124B) to each of the first light guide (122 A) and the second light guide (122A).

摘要： A catheter system (100) for treating a vascular lesion (106A) within or adjacent to a vessel wall (108A) within a body (107) of a patient (109) includes a catheter fluid (132), an energy source (124) that generates energy, an energy guide (122A) and an energy manifold (129). The energy guide (122A) includes a guide distal end (122D) that is selectively positioned near the vascular lesion (106A). The energy guide (122A) is configured to receive energy from the energy source (124) and generate a plasma bubble (134) within the catheter fluid (132). The energy manifold (129) is coupled to the energy guide (122A) near the guide distal end (122D). The energy manifold (129) includes (i) a manifold body (260) that defines a body chamber (266), the body chamber (266) being configured to retain at least some of the catheter fluid (132), and (ii) a manifold aperture (262) that extends through the manifold body (260). The energy manifold (129) directs energy from the plasma bubble (134) out of the body chamber (266) through the manifold aperture (262) and toward the vascular lesion (106A).

摘要： A catheter system (100) for treating a treatment site (106) includes an energy source (124), an inflatable balloon (104), an energy guide (122A), and a pressure sensor (258, 358). The inflatable balloon (104) is positionable substantially adjacent to the treatment site (106). The inflatable balloon (104) has a balloon wall (130) that defines a balloon interior (146) that receives a balloon fluid (132). The energy source (124) generates energy that is received by the energy guide (122 A) so that the energy guide (122A) can guide the energy into a balloon interior (146). The pressure sensor (258, 358) senses a balloon pressure of the balloon fluid (132). A method for disrupting calcification at the treatment site (106) includes the steps of generating energy with the energy source (124), positioning the inflatable balloon (104) substantially adjacent to the treatment site (106), the inflatable balloon (104) having the balloon wall (130) that defines the balloon interior (146), the balloon interior (146) being configured to receive the balloon fluid (132), receiving energy from the energy source (124) with the energy guide (122A), guiding the energy from the energy source (124) into the balloon interior (146) with the energy guide (122 A); and sensing a balloon pressure of the balloon fluid (132) with a pressure sensor (258, 358).

摘要： A catheter system (100) for treating a treatment site (106) within or adjacent to a vessel wall (1 OSA) or a heart valve includes a light source (124), a first light guide (122A), a second light guide (122A), and an optical alignment system (257). The light source (124) generates light energy (224A, 224B, 324A, 324B, 424B). The first light guide (122A) receives the light energy (224A, 224B, 324A, 324B, 424B) from the light source (124). The first light guide (122A) has a guide proximal end (122P). The second light guide (122A) receives the light energy (224A, 224B, 324A, 324B, 424B) from the light source (124). The second light guide (122A) has a guide proximal end (122P). A multiplexer (223) directs the light energy (224A, 224B, 324A, 324B, 424B) toward the guide proximal end (122P) of the first light guide (122A) and the guide proximal end (122P) of the second light guide (122A). The optical alignment system (257) determines an alignment of the light energy (224A, 224B, 324A, 324B, 424B) relative to at least one of the guide proximal ends (122P). The optical alignment system (257) adjusts the positioning of the light energy (224A, 224B, 324A, 324B, 424B) relative to the at least one of the guide proximal ends (122P) based at least partially on the alignment of the light energy (224A, 224B, 324A, 324B, 424B) relative to the at least one of the guide proximal ends (122P).

摘要： A catheter system (100) includes a power source (124), a controller (123), and a light guide (122). The power source (124) generates a plurality of energy pulses (242B, 342B). The controller (123) controls the power source (124) so that the plurality of energy pulses (242B, 342A-B) cooperate to produce a composite energy pulse (348A-B, 448A-C, 548A-F) having a composite pulse shape. The light guide (122) receives the composite energy pulse (348A-B, 448A-C, 548A-F). The light guide (122) emits light energy in a direction away from the light guide (122) to generate a plasma pulse (246A-B, 346A-B) away from the light guide (122). The power source (124) can be a laser and the light guide (122) can be an optical fiber. Each of the energy pulses (242B, 342A-B) has a pulse width, and the energy pulses (242B, 342A-B) are added to one another so that the composite energy pulse (348A-B, 448A-C, 548A-F) has a pulse width that is longer than the pulse width of any one of the energy pulses (242B, 342A-B). At least two of the energy pulses (242B, 342A-B) can have the same wavelength as or a different wavelength from one another.

摘要： A catheter system (100) for treating a treatment site (106) within or adjacent to a blood vessel (108) includes a power source (124), a light guide (122) and a plasma target (242). In various embodiments, the light guide (122) receives power from the power source (124). The light guide (122) has a distal tip (244), and the light guide (122) emits light energy (243) in a direction away from the distal tip (244). The plasma target (242) is spaced apart from the distal tip (244) of the light guide (122) by a target gap distance (245). The plasma target (242) is configured to receive light energy (243) from the light guide (122) so that a plasma bubble (234) is generated at the plasma target (242). The power source (124) can be a laser and the light guide (122) can be an optical fiber. In certain embodiments, the catheter system (100) can also an inflatable balloon (104) that encircles the distal tip (244) of the light guide (122). The plasma target (242) can be positioned within the inflatable balloon (104). The target gap distance (245) can be greater than 1 μm. The plasma target (242) can have a target face (1672) that receives the light energy (243) from the light guide (122). The target face (1672) can be angled relative to a direction the light energy (243) is emitted to the plasma target (242). The plasma target (242) can be formed from one or more of tungsten, tantalum, platinum, molybdenum niobium, iridium, magnesium oxide, beryllium oxide, tungsten carbide, titanium nitride, titanium carbonitride and titanium carbide.
