A method of performing a therapy on a prostate of a patient via transperineal access. The therapy uses an ultrasound probe. The method includes positioning a pair of stabilization members of a needle guide adjacent the perineum. The pair of stabilization members spaced apart from each other and supporting a platform configured to slide along a portion of a length of the pair of stabilization members. The needle guide is coupled to the ultrasound probe. The method further includes coupling an access needle to the platform, and sliding the platform and the access needle relative to the pair of stabilization members and the ultrasound probe so the access needle extends into the perineum. And the method further includes, using the access needle as a conduit, injecting a radiation blocking substance between the rectum and the prostate.

An artificial intelligence based vascular mapping and interventional procedure assisting platform configured to identify at least the femoral artery and the bifurcation point of the femoral artery of a patient based upon dynamic imaging of the patient. The platform may be a stroke management tool in which an angiogram and conventional bloodwork can be inputted into the platform and the platform provides one of i) classification of a stroke and stroke prediction; and whether an interventional procedure is indicated and wherein if interventional procedure is indicated then vascular mapping is provided with bifurcation points and the desired access illustrated together with a listing of accepted or counter indicated closure systems that may be used.

A transperineal biopsy guide including a guide member and a displacement member supported by the guide member. The guide member may be configured to operably couple with the transrectal probe and may include a distal end, a proximal end opposite the distal end, and a length extending along a longitudinal axis between the distal and proximal ends. The displacement member may be configured to support the access needle and displace the access needle along at least a portion of the length of the guide member between the distal and proximal ends. The access needle may extend into the subcutaneous tissue when the access needle is displaced to the distal end.

A method of performing a transperineal biopsy procedure including the steps of: inserting an access needle into one of a plurality of needle receiving ports of a displacement member of a transperineal biopsy guide that is secured to the transrectal ultrasound probe; securing the access needle to the displacement member such that a position of the access needle relative to the displacement member is maintained; imaging the prostate of the patient with the transrectal ultrasound probe; inserting the access needle into the perineal access site of the patient; and inserting the biopsy needle through the access needle and into the prostate of the patient.

A method for performing a medical procedure in an intestine of a patient is provided. The method comprises providing a system comprising: a catheter for insertion into the intestine, the catheter comprising: an elongate shaft comprising a distal portion; and a functional assembly positioned on the shaft distal portion and comprising at least one treatment element. The catheter is introduced into the patient, and target tissue is treated with the at least one treatment element. The target tissue comprises mucosal tissue of the small intestine, and the medical procedure can be configured to treat at least one of non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH).

A system comprising: one or more field generating coils configured to generate a magnetic field; a sensor comprising a shell that contains a ferrofluid, the sensor configured to be introduced in proximity to the magnetic field, wherein the ferrofluid causes distortion of the magnetic field when the ferrofluid is in proximity to the magnetic field; and one or more field measuring coils configured to: measure a characteristic of the magnetic field when the ferrofluid is in proximity to the magnetic field; and provide, to a computing device, a signal representative of the measured characteristic of the magnetic field, wherein the computing device is configured to determine one or both of a position and an orientation of the sensor based on the measured characteristic of the magnetic field.

A method and system are used to enhance a marker material to include a plurality of air bubbles. The method of manufacturing a marker includes enhancing a marker material to include a plurality of air bubbles using at least a first EFD and a second EFD. The method may include cycling repeatedly through a transfer process between a first container and a second container. A system for enhancing a marker material includes a transfer apparatus configured to receive a marker material and a selected amount of air. The system comprises a first EFD coupled to a first end of the transfer apparatus and a second EFD coupled to a second end of the transfer apparatus.

An apparatus, including a flexible insertion tube having a distal end for insertion into a body cavity, and first and second conduits configured to deliver first and second fluids, respectively, to the distal end. The distal end includes a first balloon coupled to the first conduit so that the first fluid inflates the first balloon and is delivered, via one or more spray ports in the first balloon, to tissue in the body cavity, a second balloon contained within the first balloon and coupled to the second conduit so that the second fluid inflates the second balloon, and multiple splines including a flexible, resilient material and extending along a longitudinal axis of the distal end, and configured to constrain the second balloon so that inflation of the second balloon creates lobes that form, along the longitudinal axis between the lobes, channels that direct the first fluid to the spray ports.

This application concerns a loupe-based wearable device that is enhanced by a mounted visualization aid on the housing body of at least one of the loupe eyepieces, the aid providing a dual light source, a beam splitter, and a camera directed in the same optical path as a user's eyesight such that both visible light and fluorescent dye exciting light can be directed at a site of operation to enhance real time visualization of tissue resection.
