摘要:
A pneumostoma management system for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. The pneumostoma vent includes a hydrophobic filter and/or a one-way valve.

A plurality of individual thin-walled generally disk-shaped blades are resiliently mounted in an elastomeric pad. The elastomeric pad, with its individually mounted blades, is disposed over a flexible sponge-like member. The shaving device is flexible and maintains maximum skin contact regardless of the contour of the area being shaved by providing that each individual blade is independently movable with respect to the other blades.

There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.
摘要:
A mechanism for feeding a fastener including a housing having a longitudinal axis and at least one fastener within the housing. The fastener has a crown and at least two legs extending therefrom. The fastener is disposed within the housing in a first plane parallel to the longitudinal axis. The mechanism includes an elongated actuator disposed within the housing. The actuator has a shaft substantially parallel to the longitudinal axis of the mechanism and rigidly spaced from the fastener in a second plane. The actuator has at least one radially extending advancer disposed along a length thereof, and a mechanism for rotating the actuator so that the advancer engages the fastener.

Surgical instruments and techniques are provided for creating a pneumostoma through the chest wall into the lung of a patient. The pneumostomy instruments and techniques may be used to create a pneumostoma which allows gases to escape from the lung through the chest wall and thereby treat chronic obstructive pulmonary disease.

A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing having a proximal position and a distal position. When the anvil is in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop, wherein at least one fasteners is placed around the anvil when the anvil is in distal position. And a distal end of the anvil extends distal to the distal end of the staple housing. The applier further includes a first means for moving the anvil distally during a deployment of the at least one fastener, and a second means for moving the anvil distally during the deployment of the at least one fastener, wherein the second means is independent of the first means.
摘要:
The present invention relates to devices and methods for the endoscopic treatment of hollow organs. The invention provides improved devices and methods for apposing and fixating multiple regions of the outer surface of a hollow organ. The invention is particularly useful for procedures in which multiple regions of the outer surface of the stomach are brought into apposition and fixated, for example procedures to treat gastroesophageal reflux disease (GERD) or procedures to treat obesity.
