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.

A tissue fastener assembly delivers a fastener for deployment. The assembly includes a fastener including a first member, a second member, the first and second members having first and second ends, and a flexible connecting member fixed to each of the first and second members intermediate the first and second ends and extending between the first and second members. The first member has a longitudinal axis and a through channel along the axis. The assembly further includes a deployment wire slidingly received within the through channel of the first member that pierces into the tissue and guides the first member through the tissue, a guide structure defining a lumen that receives the fastener and deployment wire and guides the deployment wire and fastener to the tissue, and a fastener configuration structure that orientates the second member in a predetermined position relative to the first member within the lumen for dependable deployment.

A system comprises a guide wire, an embolic protection basket carried on the guide wire, and a catheter carried on the guide wire adjacent the embolic protection basket. The catheter includes an elongated carrier and a balloon about the carrier in sealed relation thereto. The balloon is arranged to receive a fluid therein that inflates the balloon, and an arc generator including at least one electrode within the balloon forms a mechanical shock wave within the balloon.

A wearable infusion device comprises a reservoir that holds a liquid medicament, an outlet port that delivers the liquid medicament to a patient, a pump that holds a volume of the liquid medicament received from the reservoir and displaces substantially all of the volume of the liquid medicament when actuated, and at least a first valve, a second valve, and a third valve. The valves establish fluid connection between the reservoir and the pump when in a first valve configuration and establish fluid connection between the pump and the outlet when in a second valve configuration. At least two of the valves isolate the outlet from the reservoir when the valves are in the first valve configuration.

A transoral gastroesophageal flap valve restoration device has sufficient flexibility and dimension to be passed through the mouth, throat, and esophagus of a patient into the patient's stomach. The device includes a first member and a second member hingedly coupled to the first member. The first and second members are configured to flex in a direction to follow the esophageal path into the stomach and to be substantially rigid when forming the restored gastroesophageal flap valve.

A wearable infusion device comprises a reservoir that holds a liquid medicament, an outlet port that delivers the liquid medicament to a patient, a pump that delivers a volume of the liquid medicament from the reservoir to the outlet when actuated, and a tactile indicator representing the volume of the liquid medicament delivered to the outlet with each actuation of the pump.
摘要:
The invention provides a device, assembly, and method for transoral endoscopic restoration of a gastroesophageal flap valve. The invention also provides a self-steering and self-closing tissue fixation device for tissue fixation and an invaginator device for gripping and maneuvering tissue. The restoration device includes a longitudinal member arranged for transoral placement into a stomach, a tissue shaper carried on the longitudinal member that causes stomach tissue to assume a shape related to a gastroesophageal flap, and a tissue fixation device that maintains the shaped stomach tissue in a shape approximating a gastroesophageal flap. The tissue shaper may include a mold. The device may include the invaginator device for gripping and maneuvering esophageal tissue to aid restoration of the gastroesophageal flap, and may include the tissue fixation device.

A wearable infusion device delivers a liquid medicant to a patient. The infusion device comprises a reservoir arranged to contain a liquid medicant to be delivered beneath a patient's skin. The reservoir has an outlet through which the medicant flows and a shape that forms at least one pocket that traps air isolated from the outlet. The infusion device further includes a conduit communicating with the outlet of the reservoir, and a pump that causes the medicant to flow from the reservoir into the conduit.
摘要:
A mitral valve staple device treats mitral regurgitation of a heart. The device includes first and second leg portions, each leg portion terminating in a tissue piercing end, and a connection portion extending between the first and second leg portions. The connection portion has an initial stressed and distorted configuration to separate the first and second leg portion by a first distance when the tissue piercing ends pierce the mitral valve annulus and a final unstressed and undistorted configuration after the tissue piercing ends pierce the mitral valve annulus to separate the first and second leg portions by a second distance which is shorter than the first distance. The device is deployed within the heart transvenously through a catheter positioned in the coronary sinus adjacent the mitral valve annulus. A tool forces the mitral valve staple device through the wall of the catheter for deployment in the heart.
