Abstract: Technologies are generally provided for a vascular reinforcement device for preventing compression of a blood vessel in the presence of applied external forces applied which may occur due to pregnancy and obesity. The vascular reinforcement device may include a first portion configured to be positioned over the aorta and a second portion coupled perpendicularly with the first portion, the second portion configured to be positioned over the left renal vein for preventing the left renal vein from being compressed against the rigid aorta. A reinforcement structure may be embedded into the second portion for providing further protection from compression of the vein passing through the second portion. The vascular reinforcement device may be configured in an initial reduced profile position for delivery to the abdominal area via a delivery tube, and may be deployed into an expanded position over the aorta and the left renal vein.

Abstract: Technologies are generally provided for a trans-urethral sling delivery device for deploying a sub-urethral sling to support a urethra to treat urinary incontinence. A trocar and a delivery tube may be advanced through the urethra, and the trocar may puncture a hole in the urethral wall. The delivery tube may be configured to form a curved position such that a curved portion may extend from the hole in the urethral wall into an area surrounding the urethra near the bladder. A sub-urethral sling may be attached to a flexible delivery tool in a reduced delivery profile, and the flexible delivery tool with the attached sub-urethral sling may be advanced through the curved delivery tube. The delivery tube may be rotated to enable the delivery tool to anchor each end of the sub-urethral sling on each side of the urethra with a portion of the sling supporting the urethra from beneath.

Abstract: Technologies are generally provided for a trans-vaginal sling delivery device for deploying a sub-urethral sling to treat urinary incontinence. A delivery tool coupled with an interior of a delivery tube may be advanced through the vagina, and a pointed end of the delivery tube may puncture the vaginal wall. A sub-urethral sling may be attached to the delivery tube, and the sling may be longitudinally wrapped into a reduced delivery profile around the delivery tool within the delivery tube. The delivery tube may include a longitudinal slit opening, and the sling may be deployed from the delivery tool by rotating the delivery tool. Two delivery tubes and delivery tools may be employed to deploy each end of the sling, such that each end of the sling may be anchored on a right and left side of the urethra with a portion of the sling supporting the urethra from beneath.

Abstract: Technologies are generally provided for a vascular reinforcement device for preventing compression of a blood vessel in the presence of forces applied externally to the blood vessel which may occur due to pregnancy and obesity. The vascular reinforcement device may include a coil which may be wrapped around a left renal vein at a position where the left renal vein crosses the aorta for preventing compression of the left renal vein against the rigid aorta. The coil may be uncoiled into a long a flat position for percutaneous delivery to the abdominal area employing a laparoscopic procedure. The coil may be inserted into a delivery tube in the uncoiled position and delivered through the delivery tube employing a guiding tool. As the coil emerges from the delivery tube, the coil may be configured to form into the coiled position around the left renal vein.

Abstract: Technologies are generally provided for a vascular reinforcement device is provided for preventing compression of a blood vessel in the presence of forces applied externally to the blood vessel. The vascular reinforcement device may include a balloon having a substantially elongated shape which may be placed adjacent to a left renal vein such that when the balloon is in an inflated position, the balloon may prevent compression of the left renal vein against a rigid structure such as the aorta. The balloon may include an anchoring sheath on each end of the balloon for anchoring the inflatable balloon to fascia surrounding the blood vessel to provide stabilization. The balloon may be delivered and positioned in an initial deflated position employing a laparoscopic procedure, and once anchored in position alongside the left renal vein, the balloon may be filled with a sterile solution for inflation.

Abstract: A tissue ablation system includes a waveguide configured to leak microwave radiation through an array of subwavelength apertures.

Abstract: Disclosed are a system, device, and method for controlling a differential fluid pressure between chambers in a heart. The device includes an implantable pop-off valve that may be secured between two chambers of a heart, such as the left and right atriums. The pop-off valve is normally in a closed position. If a differential fluid pressure across the device exceeds a pre-determined value, the pop-off valve is arranged to open to enable blood flow between the two chambers of the heart. When it is determined that the differential fluid pressure is substantially below the pre-determined value, the pop-off valve is configured to close. The system and method further discloses means for implanting the device into a septal region of the heart.
