  • Patent number: 10016271
    Abstract: A prosthetic heart valve (100) includes a flexible anchoring member (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to, mounted within, or otherwise carried by the valve support. The valve support includes a plurality of posts (122) connected circumferentially by a plurality of struts (124), where the posts extend along an axial direction generally parallel to the longitudinal axis (101) and the struts extend circumferentially around and transverse to the longitudinal axis. The posts extend an entire longitudinal height HI of the valve support 120. The device also includes one or more sealing members (140) and tissue engaging elements (170) like spikes.

  • Patent number: 10004789
    Abstract: A system for delivering a therapeutic agent to a nasopharyngeal mucosa target comprises a foam generating mechanism, a gas, a therapeutic agent in liquid form that inhibits mucus production, and a delivery device. Actuation of the foam generating mechanism entraps gaseous bubbles from the gas in the liquid thereby forming a foam. The therapeutic agent is dispersed in the foam which has an expanded configuration adapted to fill a nasopharyngeal space and deliver the therapeutic agent to the mucosa targets. The delivery device is for delivering the foam to the nasopharyngeal space. The foam may also have a collapsed configuration for removal from the nasopharyngeal space or for concentration of the therapeutic agent onto the mucosa.

  • Patent number: 9956410
    Abstract: Methods and apparatus are provided for renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. It is expected that renal neuromodulation (e.g., denervation) may, among other things, reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease. Embodiments of the present invention are configured for extravascular delivery of pulsed electric fields to achieve such neuromodulation.

  • Publication number: 20180104005
    Abstract: Methods and apparatus are provided for non-continuous circumferential treatment of a body lumen. Apparatus may be positioned within a body lumen of a patient and may deliver energy at a first lengthwise and angular position to create a less-than-full circumferential treatment zone at the first position. The apparatus also may deliver energy at one or more additional lengthwise and angular positions within the body lumen to create less-than-full circumferential treatment zone(s) at the one or more additional positions that are offset lengthwise and angularly from the first treatment zone. Superimposition of the first treatment zone and the one or more additional treatment zones defines a non-continuous circumferential treatment zone without formation of a continuous circumferential lesion. Various embodiments of methods and apparatus for achieving such non-continuous circumferential treatment are provided.

  • Publication number: 20180078758
    Abstract: Methods and apparatus are provided for bilateral renal neuromodulation, e.g., via a pulsed electric field, via a stimulation electric field, via localized drug delivery, via high frequency ultrasound, via thermal techniques, etc. Such neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, neuromodulation is applied to neural fibers that contribute to renal function. In some embodiments, such neuromodulation is performed in a bilateral fashion. Bilateral renal neuromodulation may provide enhanced therapeutic effect in some patients as compared to renal neuromodulation performed unilaterally, i.e., as compared to renal neuromodulation performed on neural tissue innervating a single kidney.

  • Patent number: 9901443
    Abstract: Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having a first portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a valve support coupled to a second portion of the anchoring member, configured to support a prosthetic valve and having a cross-sectional shape. In some embodiments, the first portion of the anchoring member is mechanically isolated from the valve support such that the cross-sectional shape of the valve support remains sufficiently stable that the prosthetic valve remains competent when the anchoring member is deformed in the non-circular shape.

  • Publication number: 20180021555
    Abstract: A system for delivering a therapeutic agent to nasopharyngeal mucosa tissue has a shaft, a porous pad of compliant material coupled to the shaft near the distal end, and a drug reservoir. The porous pad is configured to expand from a contracted configuration to an expanded configuration. The expanded configuration is adapted to engage and conform to the mucosa tissue in a nasal cavity, and the contracted configuration has a size suitable for introduction into the nasal cavity. The drug reservoir holds a therapeutic agent and is at least partially covered by the porous pad. The drug reservoir is configured to release a fixed volume of the therapeutic agent into the porous pad within a period of less than about 120 minutes, and has a wall with a plurality of channels fluidly coupled with the porous pad.

  • Publication number: 20170266422
    Abstract: Methods and systems for delivering toxin and toxin fragments to a patient's nasal cavity provide for both release of the toxin and delivery of energy which selectively porates target cells to enhance uptake of the toxin. The use of energy-mediated delivery is particularly advantageous with light chain fragment toxins which lack cell binding capacity.
