  • Patent number: 10561496
    Abstract: Disclosed herein are designs for improved inflatable structures for use during minimally invasive cardiovascular procedures. These inflatable structures facilitate the perfusion of blood through an anatomical structure, such as a heart valve, during the cardiovascular procedure. The inflatable structures are formed of a plurality of balloons arranged radially around a central location. The plurality of balloons form a lumen through which blood flows. Each balloon of the plurality is shaped or configured to stabilize the adjacent balloons, limiting their movement relative to each other. For example, some embodiments can feature balloons with a keystone shape that limits movement of the balloons inward toward the lumen. Some implementations can also include a support coil running through the lumen. The support coil holds enables the lumen to be open to perfusion even in the early stages of balloon inflation.

  • Patent number: 10449000
    Abstract: Devices, methods and systems for removing unwanted tissue from within a patient's vasculature system are provided. Specifically, a laser ablation catheter having a tip with an open, arched-shaped cross section is described. The cross section of the tip enhances the catheter's ability to ablate, separate, and/or dilate the various layers within a patient's vasculature, thereby facilitating the removal undesirable lesions and fibrous tissue within a patient's vasculature.

  • Patent number: 10413362
    Abstract: A multiwavelength laser-based intense light source is described having applications in incision, excision and ablation of soft tissues with minimal collateral tissue damage. The light source combines the output of a plurality of relatively low power laser sources, emitting radiation in the region of the electromagnetic spectrum bounded by approximately 350 nm to 450 nm, where the combined output may be coupled into a single fiber optic energy delivery device: a standard surgical probe. Spectral and spatial beam combining are used to produce an incoherent light source with relatively low average power at any given wavelength, but with high total power and superior M2 beam quality, targeting multiple chromophores in target tissue and tissue breakdown product chromophores for consistently high and target absorption without indiscriminant char interference throughout a surgical procedure.

  • Patent number: 10406330
    Abstract: Catheters or other tubular devices and methods for using them to perform a medical procedure are provided. In an exemplary embodiment, a tubular device includes an elongate tubular member comprising a proximal end, a distal end sized for introduction into a patient's body, and a lumen extending between the proximal and distal ends; an expandable member on the distal end comprising an outer impermeable membrane with an inner surface surrounding a substantially enclosed interior space; and a fiber network within the interior space coupled to the inner surface and configured to limit expansion of the membrane when inflation media is directed into the interior space from the lumen to expand the membrane to an expanded configuration.

  • Patent number: 10363391
    Abstract: A catheter including an outer tube; a first inner tube disposed within the outer tube; a second inner tube disposed within the outer tube and parallel to the first inner tube, and having an insertion opening at its proximal end and a distal end opening at its distal end; and a first core wire and a second core wire disposed between the first inner tube and an outer tube. The second inner tube extends from a medial region of the catheter to a distal end of the catheter. A distal end of the first core wire is located distal to the insertion opening of the second inner tube, and a distal end of the second core wire is located proximal to the insertion opening of the second inner tube. The second core wire can move between the outer tube and the first inner tube.

  • Patent number: 10357362
    Abstract: Heart valve delivery systems and methods for providing a clinician with feedback during a stented prosthetic heart valve delivery procedure. Feedback is provided using piezochromatic indicators incorporated into elements of the delivery device, such as the handle assembly, shaft assembly and capsule to indicate when detrimental forces, or forces nearing those that are detrimental, are being applied to the delivery device during the prosthetic heart valve loading, delivery or deployment procedure. Other embodiments incorporate a feedback indicator to indicate that a delivery device has previously been used and is not in a new condition.

  • Patent number: 10307201
    Abstract: Devices, systems, and methods for degassing fluid prior to applying fluid to a treatment site during ablation therapy are provided. In one embodiment, an ablation system can include an elongate body, an ablation element, a heating assembly, and a fluid source. Fluid in the fluid source can be at least partially degassed prior to being provided as part of the system, or, in some embodiments, a degassing apparatus can be provided that can be configured to degas fluid within the system prior to applying the fluid to the treatment site. The degassing apparatus can include one or more gas-permeable and fluid-impermeable tubes disposed therein, which can allow gas to be removed from fluid passing through the apparatus. Other exemplary devices, systems, and methods are also provided.

  • Patent number: 10293145
    Abstract: One embodiment provides a balloon catheter which has an inner tube having a main lumen and an outer tube which forms an expansion lumen. A part of the inner tube is connected to the outer tube at a position closer to the proximal end than a balloon, a side hole is open at the connection section, and a weak section is provided to the inner tube a position closer to the distal end than the side hole. The weak section has lower rigidity than the remaining portion of the inner tube. When the balloon is expanded by fluid supplied to the expansion lumen, the weak section is pressed by the fluid pressure to thereby close the main lumen of the inner tube.

  • Patent number: 10226604
    Abstract: Various systems and methods are provided for reducing pressure at an outflow of a duct, such as the thoracic duct or the lymphatic duct, for example, the right lymphatic duct. A catheter system can be configured to be at least partially implanted within a vein of a patient in the vicinity of an outflow port of a duct of the lymphatic system. The catheter system includes first and second selectively deployable restriction members each configured to be activated to at least partially occlude the vein within which the catheter is implanted and to thus restrict fluid within a portion of the vein. The catheter system includes an impeller configured to be driven by a motor to induce a low pressure zone between the restriction members by causing blood to be pumped through the catheter when the restriction members occlude the vein.
