A61F 2/07

Abstract:

An intravascular cutting device described herein uses high-pressure water, saline, or other fluid to cut tissue and other materials including but not limited to calcified tissue, stents, stent grafts, and other devices. In some embodiments, the cutting device includes a working end that has a nozzle with a hole to allow the release of a high-pressure fluid jet. Opposite of the nozzle is a catch plate or deflector anvil that prevents the fluid jet from cutting healthy tissue. The device user will place the item to be cut between the nozzle and catch plate and then advance the device along the item to be cut as the fluid jet is activated, thus cutting the object as it advances.

Abstract:

Elastomeric bypass grafts (EBG) described herein can be pre-stretched and are able to accommodate limb flexion-induced or organ-induced deformations without producing excessive tortuosity or stresses. In comparison to known grafts, EBGs demonstrate significantly less tortuosity when used for lower extremity repair during limb flexion, and improved flow patterns within the grafts. Longitudinally pre-stretched EBGs described herein improve hemodynamics and may produce better healing responses in the harsh mechanical environment of the lower limbs, compared to known grafts.

Abstract:

This document describes devices, systems, and methods for automatically deploying intravascular devices. For example, this document describes devices, systems, and methods for automatically deploying and controlling intravascular catheter-based devices for treating catastrophic bleeding from large and medium size vessels such as, but not limited to, the aorta or iliac arteries. In some embodiments, an operator/care giver will simply press the system against the patients body proximate to a desired site of insertion, or will attach the system to the patient proximate to the desired site of insertion. The operator will then activate the system. Thereafter, the system will use built in imaging (e.g., ultrasound) to locate a proper insertion point and then deploy an access needle to attain vascular access. With that, the system will then automatically insert the intravascular device into the patient.

Abstract:

Some implementations of an endovascular device include a stent graft with an expandable tubular metallic frame and a covering material disposed on at least a portion of the metallic frame. The stent graft defines a lumen therethrough. In a particular embodiment, a first balloon is disposed around an outer periphery of the stent graft, a second balloon is disposed around the outer periphery of the stent graft and spaced apart from the first balloon, and a third balloon is disposed within the stent graft lumen between the first balloon and the second balloon. The third balloon can be inflated to fully or partially occlude the lumen. The first and second balloons can be individually inflated to fully or partially shunt blood flow from a blood vessel through the stent graft. In some embodiments, sensors and an automated control unit are included to automate the operations of the endovascular device.

International Classification:

A61B 17/221

Abstract:

A surgical snare device for engaging an object in a body passage and that employs multiple loops for snaring the object. The loops, which can be made from a single elongated line or separate lines, are positioned at locations that substantially span across the diameter of the body passage. A tubular membrane cap is included which is made from a liner coupled with structural elements made of expandable wire for support. The membrane cap is selectively deployed from a sheath and radially expandable to envelop the captured object so that withdrawing the object is more secure and any sharp edges on the object do not damage walls of the body passage. The loops and membrane cap can be made from a metal, a metal alloy, or polymer. Perforations can be formed in the liner to allow fluid to pass through the membrane cap.
