摘要： Methods and devices for visualizing and accessing a region inside a body are described. One embodiment of a device includes a working catheter which slides along an open track in a visualization catheter. The visualization catheter is inserted into the body to locate a region of the body with the aid of the visualization element. The working catheter then slides along the track to reach the region, and a working element is inserted through the working catheter to access the region, again with the aid of the visualization element. The methods and devices may also be used to access a variety of internal cavities, soft tissues and organs, and the mediastinal space.

摘要： A surgical electrode consisting of an insulated stainless steel wire having surgical needles conductively affixed at one or both ends, at least one needle having a pointed end and a nonpointed end with a blind hole or flange in the nonpointed end thereof, and the blunt end of a blunt pointed pin fitted into said hole or flange and a crimp in said nonpointed end of the needle retaining said pin in said hole or flange with controlled pull-out characteristics, said pin conductively and permanently affixed at the other end to said wire, whereby said pin may be pulled out of said blind hole or flange and the blunt end of said pin used as an electrical jack for connection to a pacemaker or similar electric current generating or monitoring device. The electrodes are particularly useful as temporary heart pacer electrodes for cardiac stimulation during and after surgical operations.

摘要： The physical properties of structural surgical elements which are made from bioabsorbable materials having a glycolic ester linkage can be controlled so that the rate of strength loss and degradation in vivo is altered to achieve disintegration into fragments suitable for removal from or passage through the body without the need for waiting until the material is absorbed. This is achieved by a method of modifying the element through various chemical and/or physical treatments, preferably irradiation, or combinations thereof, with the result that bioabsorbable structural surgical elements are made more controllable in their strength loss and degradation pattern.

摘要： Methods and devices for pericardial access are described. One embodiment of a device includes a distal portion with a visualization element, along with a retractable access element. The distal portion is inserted into and navigates through the body to locate the pericardium with the aid of the visualization element. The access element is then extended and used to create an access site in the pericardium, again with the aid of the visualization element. The methods and devices may also be used to access other internal cavities, other soft tissues and organs, and the mediastinal space.
