| 20100168667 | CATHETER HAVING PROXIMAL HEAT SENSITIVE DEFLECTION MECHANISM AND RELATED METHODS OF USE AND MANUFACTURING - Disclosed herein are various deflectable catheter systems that utilize materials having negative coefficients of thermal expansion to cause the catheter to deflect. A representative embodiment of the present invention includes a catheter having a heat-sensitive control member located outside the distal end of the catheter, but which is in mechanical communication with the distal end of the catheter such that heat may be applied to the control member to cause the distal portion to deflect. The applied heat, however, does not introduce any significant heat into the distal end of the catheter. The system may also include a processor to estimate an amount by which the catheter has been deflected based in part on temperature information of the control member, or even resistance measurements for the control member. The system may also include calibration systems and methods. Also disclosed herein are methods of use and methods of manufacturing system that utilize materials having negative coefficients of thermal expansion as control members. | 07-01-2010 |
| 20100168717 | MULTI-LUMEN MEDICAL DEVICES AND METHODS OF MANUFACTURING SAME - A method of manufacturing a catheter shaft includes extruding an inner polymeric layer having a main lumen and two or more side lumens spaced about the main lumen; forming an outer polymeric layer about the inner polymeric layer; and inserting at least one elongate member, such as a wire, through each side lumen of the inner polymeric layer. The side lumens are less than about ⅕ the size of the main lumen. The method may further include the step of forming a braided layer between the inner polymeric layer and the outer polymeric layer. In an alternate embodiment, the method includes co-extruding an inner polymeric layer and a multi-lumen layer, the multi-lumen layer having two or more side lumens; forming an outer polymeric layer about the multi-lumen layer; and inserting at least one elongate member through each side lumen. Catheter assemblies made according to the described methods are also disclosed. | 07-01-2010 |
| 20100249568 | MEDICAL DEVICES HAVING AN ATRAUMATIC DISTAL TIP SEGMENT - A kit for the diagnosis or treatment of tissue in a body cavity includes an introducer and a catheter insertable through the lumen of the introducer having a proximal segment, a working segment and a flexible distal tip segment. The flexible distal tip segment is located adjacent the distal end of the working segment and includes a proximal end, a distal end and a pre-formed bend or curve that permits the catheter to exit the introducer in a lateral direction relative to the introducer body to prevent inadvertent damage to the tissue during a medical procedure. All or part of the working segment and the flexible distal tip segment may be adhesive-filled. The catheter may also include a plurality of sensing and/or energy delivery elements on the working segment and a shape-memory wire terminating at the distal end of the working segment. Methods of use and methods of manufacturing are also described. | 09-30-2010 |

| 20100108249 | Method and Apparatus For Making Sealed Pouches - A method and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate. | 05-06-2010 |
| 20100284633 | Discrete pouch having a closure system secured thereto - A discrete pouch is disclosed having a closure system transversely secured across an open end thereof. The discrete pouch includes first and second major surfaces joined together by a pair of sides. The discrete pouch also has a closed bottom, an open top, and a closure system secured to the second major surface adjacent to the open top. The discrete pouch is designed to have the open top sealed after it is filled with products and the closure system is capable of being opened and closed multiple times. | 11-11-2010 |
| 20100285942 | Machine for securing a closure system onto a discrete pouch - A machine is disclosed for securing a closure system onto a discrete pouch. The machine includes first, second and third stations. The first station is capable of advancing discrete pouches and lifting and folding a portion of a first major surface of each pouch upon itself to form a lip, and exposing an inner surface of a second major surface. The second station is capable of positioning and attaching a closure system transversely across the exposed inner surface. The closure system includes a track having first and second legs each having an outer surface. The first and second legs are joined together by an opening/closing mechanism which includes a movable member capable of being moved back and forth. The third station is located downstream from the second station and is capable of unfolding the lip and securing opposite ends of the lip to the outer surface of the second leg. | 11-11-2010 |
| 20100285943 | In-line method for securing a closure system onto a discrete pouch - An in-line method is disclosed for securing a closure system onto a discrete pouch. The method includes advancing a discrete pouch through a first station in a machine direction with the closed bottom of the pouch being the leading edge and a first major surface of the pouch faces upward. The first major surface is folded upon itself to form a lip having an exposed first surface while a second major surface of the pouch has an exposed inner surface. The method also includes routing the pouch to a second station where a closure system is transversely attached across the exposed inner surface. The closure system includes an opening/closing mechanism. The method further includes routing the pouch to a third station where the lip is unfolded and opposite ends of the lip are secured to the outer surface of the closure system. | 11-11-2010 |
| 20100331158 | Method and Apparatus For Applying Closures To Pouches - A method and machine for applying a closure to a series of pouches includes a conveyor extending at least partially through the machine, first and second (optional) infeed modules, a culling module (optional), a replacement infeed module (optional) and a closure module (optional). The infeed modules feed pouches to the conveyor. The culling module includes a sensor that senses an undesired pouch in the series of pouches, and a rejection module that culls the undesired pouch in response thereto. The replacement infeed module feeds a replacement pouch into the gap left by the undesired pouch. The conveyor may be at least partially an intermittent conveyor. The infeed modules may be in a plane with the conveyor. The closure module may be a recloseable closure module, a zipper closure module or a slider closure module. The culling module may be part of each infeed module, and/or distributed over several locations. | 12-30-2010 |
