摘要:
A wearable infusion device delivers a liquid medicament, such as insulin, to a patient. The device comprises a base that contacts a patient's skin, a reservoir arranged to contain a liquid medicament to be delivered to beneath a patient's skin, a pump that causes the medicament to flow from the reservoir, and a level indicator that provides an indication of medicament level.

Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together. The fasteners include a first member, a second member, and a connecting member extending between the first and second members. The first and second members are substantially parallel to each other. The fasteners may be deployed in limited spaces and in various applications including the restoration of a gastroesophageal flap valve.

An intravascular support device includes a support or reshaper wire, a proximal anchor and a distal anchor. The support wire engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed. The anchors and support wire are designed such that the vessel in which the support is placed remains open and can be accessed by other devices if necessary. The device provides a minimal metal surface area to blood flowing within the vessel to limit the creation of thrombosis. The anchors can be locked in place to secure the support within the vessel.

The present invention generally relates to methods and apparatus for use in endovascular and intraoperative procedures providing arterial blood-flow for perfusion of ischemic myocardium. Aspects of the present invention provide a conduit between a non-coronary sinus of the aorta and a coronary vein. The conduit traverses a portion of the right atrium and the coronary sinus, and is located entirely within the heart and aorta. Arterial blood flows from the aorta through the conduit and into the coronary venous circulation towards the ischemic region of the heart. All procedures described herein may be performed endovascularly, and further may be performed while the patient's heart is beating.
