Abstract: A cannula (10) receives surgical instruments (120) for performing a surgical procedure on a body (130). The cannula (10) comprises a tube structure (12) defining a passage (16) through which the surgical instruments (120) are inserted into the body (130). The tube structure (12) has a proximal end (20) and a distal end (62). The tube structure (12) includes an expandable portion (40) for enabling an increase in the cross-sectional area of the passage (16) at the distal end (62). The expandable portion (40) of the tube structure (12), when expanded, has a conical configuration.

Abstract: One device in accordance with the present invention includes a surgical device for creating channels in tissue of a patient. The device includes a catheter defining a lumen and a transducer assembly carried by the catheter along a lengthwise dimension of the catheter. An end effector is operatively coupled to the transducer assembly and extends distally relative to the transducer assembly. The end effector has a vibrating channel-forming tip wherein the channel-forming tip is adapted to create channels in the heart of a patient. A method in accordance with the present invention includes the steps of inserting an end effector having a tip into a patient, placing the tip of the end effector in direct contact with a surface of the heart, energizing the end effector to cause the tip to vibrate, piercing through the surface of the heart with the tip to create a channel, and removing the end effector.

Abstract: A liquid crystal film laminate embodies an indicator component and a supportive and protective component removable from the indicator component to provide maximum flexibility and minimum mass in the resulting indicating article. The indicator component includes a liquid crystal film and may include a protective layer and/or an adhesive layer. The film has an outer surface which forms one of two opposite side surfaces on the indicator component. The supportive and protective component includes two release surfaces provided by at least one release sheet, such release surfaces separably contacting respective ones of the indicator component side surfaces in covering relation thereto, for removably supporting and protecting the indicator component. The outer surface of the film thereby is exposed to unobstructed view upon removal of the supportive and protective component, for maximum clarity of the indication given by the film. The maximum total thickness of the indicator component preferably is about 4 mils.
