摘要:
A tool that has an introducer having a space therein and a distal aperture at the distal end thereof, and a spike movable within the introducer, may be used in a surgical method for treating a vessel wall. A tissue plug may be removed from the vessel wall with the spike, whereby an opening remains in the vessel wall. The spike then may be moved within the space in the introducer in a direction away from the longitudinal centerline of the distal aperture. An object then may be delivered through the introducer and out of the distal aperture to the opening in the vessel wall.

A surgical tool for performing anastomosis may include a handle and a tissue effector connected by a shaft, at least party of which may be flexible. The tissue effector may include a staple holder connected to an anvil.

An anastomosis system for connecting a graft vessel to a target vessel includes spaced-apart arms, and an anvil connected to those arms, where that anvil has a blunt distal end. The anvil is insertable into the target vessel. One or more connectors, such as staples, may be deployed from each arm to connect the graft vessel to the target vessel.

A mitt worn on a hand for cleaning. The mitt includes a section for the palm of the hand, a section for the fingers, and a compartment on either side of a central axis of the mitt for a thumb. The mitt is capable of being used on either hand, and both sides of the mitt may be used without moving the mitt from one hand to the other. The mitt is formed using an electrostatically-charged material to optimize cleaning efficiency. Also disclosed is a method of forming a mitt for cleaning.

An applicator is disclosed which includes a thin walled member adapted to hold and dispense a substance. The thin walled member is formed from at least two separate and distinct layers and has first and second spaced apart ends. The applicator also has an outwardly extending fingergrip ring integrally formed adjacent to the second end which serves to facilitate control of the applicator, facilitate comfortable insertion of a substance into a body cavity or on an area of the skin, and easy removal of the applicator.

A luer lock connector is disclosed. The luer lock connector includes a connector body having a distal end, a proximal end, and a gripping portion between the distal end and the proximal end. A substantially flexible material is disposed on at least the outer surface of the gripping portion of the connector body. An intravenous line is coupled to the distal end of the connector body. A luer connector fitting is disposed on the proximal end of the body, the luer connector having an outer diameter less than a maximum exterior thickness of the gripping portion of the connector body.

A hybrid power source includes an electric power source, a first hydraulic pump powered by the electric power source, a hydrocarbon burning power source, and a second hydraulic pump powered by the hydrocarbon burning power source. A hydraulic fluid output is fed by a combined output from the first hydraulic pump and the second hydraulic pump. A controller is provided for dynamically calculating hydraulic fluid requirements at the hydraulic fluid output as work is performed. The hydraulic fluid requirements are primarily provided by the first hydraulic pump powered by the electric power source and supplemented, as directed by the controller, by the second hydraulic pump powered by the hydrocarbon burning power source.

Systems and methods for treating internal tissue defects, such as septal defects, with clip-based devices are provided. An exemplary clip-based device includes a tubular body having at least a first and a second deflectable member coupled thereto. The first and second members are coupled on opposite ends of the tubular body and configured to deflect between an undeployed configuration and a deployed configuration. In the deployed configuration, each member extends outwardly away from the tubular body in a position configured to abut a tissue surface. The first and second members are preferably configured to maintain a tissue wall therebetween and at least partially close any opening in the tissue wall.

A tubing injector head, includes a main body adapted for mounting on a well. A pair of gripper chain supports are mounted to the main body. Each gripper chain support has an upper chain sprocket at an upper end and a lower chain sprocket at a lower end. A drive motor drives the upper chain sprocket to move a gripper chain along a bearing surface. A tubing channel is positioned between the gripper chain supports. Telescopic cylinders are provided for creating relative movement of the gripper chain supports, while maintaining the first bearing surface and the second bearing surface in parallel spaced relation. The telescopic cylinders move the gripper chains into or out of engagement with tubing positioned in the tubing channel.
摘要:
Systems, devices and methods for treating internal tissue defects, such as septal defects, are provided. An exemplary method of treating an internal tissue defect, specifically a method of closing a patent foramen ovale (PFO), can include passing a closure element from a right atrium through a septal wall in a first location and into the left atrium. A capture device, which can be configured as a snare-like device, can be used to capture the closure element in the left atrium and pull the closure element back through the septal wall in a different, second location, such that the closure element is routed over the PFO. The closure element can then be anchored and/or locked against the septal wall such that the PFO is at least partially closed.
