Abstract:
Device sand methods for improving cardiac function are provided. The device includes a dome structure having a top end with an engagement element disposed thereon. The dome structure is moveable from a first inside out configuration to a second deployed configuration, and the dome structure is biased in the second deployed configuration. The dome structure includes a plurality of anchor members disposed around a bottom open end of the dome structure.
Abstract:
A medical device for regulating fluid flow within one or more lungs of a patient is disclosed. The medical device includes an elongate tubular member, a first extension, a second extension, and a valve member. The elongate tubular member includes a first plurality of channels extending between a proximal and distal ends. The first and second extensions defines a second and third plurality of channels, respectively, each extending from the distal end of the elongate tubular member and configured for placement in a first and second passageway of a lung. The valve member operably couples to the elongate tubular member and is configured to transition between a first position and a second position. The valve member prevents fluid flow to first set of the first plurality of channels in the first position and prevents fluid flow to second set of the first plurality of channels in the second position.
Abstract:
A medical device assembly may include an elongated guidewire, an elongated flexible tubular membrane disposed about the guidewire, and a percutaneous medical device, wherein the membrane is configured to permit the percutaneous medical device to pass through the lumen. A method of advancing a medical device through a vessel may include advancing an elongated flexible tubular membrane through the vessel to a treatment site, inserting the medical device into the membrane, and advancing the medical device through the membrane while maintaining the membrane in an axially stationary position relative to the vessel.
Abstract:
A medical device for permanent implantation in a circulatory system of a patient may include an implant configured for percutaneous or minimally-invasive insertion into the patient, at least one connector fixedly attached to the implant and configured to releasably attach to a delivery device, the at least one connector being exposed to blood flow within the circulatory system following implantation, and an anti-thrombus feature configured to transition from an undeployed state to a deployed state.
Abstract:
A valvuloplasty device comprises an expandable anchor and an expansion member mounted about an outer surface of the expandable anchor. The expansion member is either an annular balloon or a sleeve. The valvuloplasty device can be used for valvuloplasty and for valve implantation.
Abstract:
Devices, systems, and methods for treating stones in anatomical structures are disclosed. A device may include an elongate member and a tubular member extending distally from the elongate member. The elongate member may define one or more lumens with an opening at a distal end of the elongate member. The tubular member may be configured to collapse to a pre-determined shape when in a relaxed state and expand in response to receiving an object. The device may be used with a scope, such as a ureteroscope, lithotripsy devices, and/or other medical devices or systems.
Abstract:
System for endocardial injection are disclosed. An example system may include a first steerable catheter having a first lumen formed therein. A second steerable catheter may be disposed within the first lumen. The second steerable catheter may have a second lumen formed therein. An injection catheter may be disposed within the second lumen. The injection catheter may have a distal end region. The distal end region may include an imaging section and a needle section. The system may include an imaging device configured to be disposed within the imaging section.
Abstract:
The present disclosure provides a tissue debridement device and describes an example treatment for ANP using the tissue debridement device. The tissue debridement device has a sheath, a distal tip, and a plurality of rotating tines coupled to the distal tip and the sheath. The distal tip can be adjusted to be closer or further from the sheath to change a diameter of the rotating tines, thereby changing a cutting diameter of the tissue debridement device.
Abstract:
Methods and systems for securing a medical implant at a valve. An illustrative method may include advancing a delivery system though a vasculature to a target location. At the target location, the delivery system may be proximally retracted to expose a medical implant carried within a lumen of the delivery system. The medical implant may be radially expanded from a collapsed delivery configuration an expanded deployed configuration. A fixation mechanism delivery system may be advanced through the vasculature to the target location. A first fixation mechanism configured to engage a native tissue and a portion of the medical implant may be deployed from the fixation mechanism delivery system. After deploying the fixation mechanism, the medical implant may be released from the delivery system.
Abstract:
The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices, systems and methods for improved efficacy of radiotherapy treatment of hypoxic tumors. For example, the disclosed devices, systems and methods may statically or continuously oxygenate hypoxic tumors immediately prior to or simultaneous with irradiation.
