20090275918 | PANCREATIC DELIVERY CATHETER - Pancreatic delivery catheters which facilitate direct intravascular access to the pancreas are described herein. A catheter which is configured particularly for pancreatic access may generally comprise a distal section which defines three curves each extending in an alternating pattern and a proximal section with an additional curve in an opposing direction. A primary curve defined along the distal section may define an acute angle with respect to a secondary curve and which also curves in an opposite direction. The secondary curve may define an acute angle with respect to both the primary curve and a tertiary curve which is proximal of the secondary curve. Similarly, a tertiary curve may extend in an opposite direction from the secondary curve. A quaternary curve along the proximal section may extend in an opposite direction from the tertiary curve. | 11-05-2009 |
20090131827 | APPARATUS AND METHODS FOR TISSUE DISRUPTION - Apparatus and methods for tissue disruption are disclosed where a tissue disruptor may have various configurations extending from the distal end of a flexible aspiration cannula. The devices can have aspiration and/or irrigation systems configured to provide aspiration pressure and/or irrigate with fluid at the distal end of the cannula. The cannula can be configured to rotate or disrupt the matrix of bone marrow and extract the marrow in vivo through a single opening. The cannula shaft itself may be fabricated utilizing multiple layers of material such that the cannula is flexible yet sufficiently stiff to transmit a torque therealong. | 05-21-2009 |
20090030338 | ACCESS GUIDE AND METHODS OF USING THE SAME - Devices and methods for guiding surgical tools are disclosed. The guided surgical tools can be used to extract body tissue from an enclosed body cavity. The guide can have multiple channels for the surgical tools to pass through the guide. The channels can converge and exit at a single exit port. The channels can have distinct entry ports. The guide can have a configuration to provide stable seating at or adjacent to the target site. | 01-29-2009 |
