A catheter devices/systems and methods therefrom are described herein for treating acute kidney injury, especially the contrast-induced acute kidney injury wherein the devices may prevent the contrast dyes from entering into kidney and/or facilitate blood flow of kidney by said catheter system.

Embolism treatment devices, systems, and methods are provided. In one embodiment, an embolism treatment system includes a flexible elongate member configured to be positioned within a blood vessel of a patient, the flexible elongate member comprising a distal portion and a proximal portion; an ultrasound imaging component positioned at the distal portion and configured to emit ultrasound energy towards a blood clot within the blood vessel and collect an image signal representative of the blood clot; a treatment component positioned at the distal portion and configured to treat the blood clot; and a flow sensing component positioned at the distal portion and configured to determine a blood flow measurement within the blood vessel associated with the blood clot.

Methods and apparatus for inducing weight loss using blood flow control are described herein. The apparatus and methods operate by controlling blood flow to the stomach and/or small bowel.

A surgical drape (100) is described that is aimed at providing a way to direct a maximum amount of fluid (e.g., distention fluid) discharged from the patient's uterine cavity to a collection point, such as a fluid management system, during a hysteroscopic procedure. The surgical drape may include a cover portion (105) and a collection portion (110) that is attached to the cover portion (105). The cover portion (105) may define an opening (115) that provides a surgeon with surgical access to the patient for performing a medical procedure. The collection portion (110) may include a main panel (120) that can be attached to the patient's back distally of the gluteal cleft (e.g., via an adhesive strip). The main panel (110) may include a pocket (170), via which the surgeon may insert his hands to position the main panel (110) under the patient without disturbing the sterile field.

Pulsatile balloon catheter systems are provided. Aspects of the systems include: a pulse generator; and a balloon catheter assembly operably connected to the pulse generator. In embodiments, the balloon catheter assembly includes: a proximal connector operably connecting the balloon catheter assembly to the pulse generator and configured to transduce a first pulse energy generated by the pulse generator to a second pulse energy; a distal balloon; and a catheter component, where the catheter component includes a fluidic passage operably positioned between the proximal connector and the distal balloon, which passage is configured to propagate the second pulse energy from the proximal connector along the fluid passage to the distal balloon. Also provided are balloon catheter assemblies and kits that include the same. Also provided are systems and methods for assessing vessel compliance in-vivo. Also provided are systems and methods for determining system state of balloon catheter systems. The systems, assemblies and kits find use in a variety of different applications, including balloon angioplasty applications.

A method is provided for reducing the risk of sustaining a traumatic brain injury caused by a traumatic event that includes identifying a subject at risk of sustaining a traumatic brain injury, and then precisely increasing the partial pressure of carbon-dioxide (CO.sub.2) in the blood of the subject (pCO.sub.2). This method can be applied to raise the CO.sub.2 and pCO.sub.2 to improve orthostatic hypotension in conditions such as dysautonomias (like Positional Orthostatic Tachycardic Syndrome POTS) and to facilitate the drive to breathe in conditions like Central Sleep Apnea (CSA) and Sudden Infant Death Syndrome (SIDS). The pCO.sub.2 of the person is increased by placing a breathing apparatus over the mouth of the person through which the person must breath, wherein the breathing apparatus includes an enlarged dead space volume in which expired CO.sub.2 collects to be inhaled or re-breathed by the person on the next inhalation.

A method of embryo transfer (ET) that improves fertility rates by eliminating transferred air during the procedure is provided. Also provided is a method for hormonally enhancing the uterine wall of a patient either prior to or during the time of ET. Quantitative administration of transfer solutions is accomplished with a modified apparatus that provides for implantation of an embryo into the uterus of a patient. The apparatus comprises an outer sheath and an inner lumen arranged to be slidably disposed within the outer sheath. The inner lumen includes at least one visual marker situated on the exterior surface adjacent its distal end thereof.

A fracture mobility testing system is provided for use in surgical procedures for augmenting vertebral bodies having collapsed due to compression fractures. The testing system is utilized to determine if the cortical shell of the vertebral body has begun to heal over the fracture lines to the point at which height restoration is not possible. Depending on the feedback provided by the testing system, the surgeon may elect to proceed with any of a variety of known height restoration techniques if the fractured portions of the vertebral body are still mobile, or may elect for a simple vertebroplasty procedure without height restoration if the feedback from the testing system determines that the cortical outer portions of the fractured vertebral body have fused to one another to the point at which height restoration is no longer an option.
