20160089089 | SYSTEMS AND METHODS FOR DIGITAL PREDICTIVE DISEASE EXACERBATION AND PRE-EMPTIVE TREATMENT - The system described herein collects patient data passively and non-passively via onboard and external sensors, and combines the data with past clinical history to generate digital biomarkers. The collected data can also be further combined with other data generating systems to more accurately predict disease exacerbations. The system monitors the digital biomarkers in real-time, and can detect a change in the disease state prior to clinical decompensation and suggest pre-emptive intervention. The system enables a patient to be treated early in the clinical timeline when the disease exacerbation is at the subclinical level rather than waiting until the disease exacerbation reaches the clinical level. Acting when the exacerbation is at the subclinical level enables preemptive treatment rather than reactive treatment, which is often more cost effective while improving clinical outcomes. The system is able to make the predictions by detecting subclinical changes in digital biomarkers that are generated from respiratory, cardiac, patient reported symptoms, user behaviors, and environmental triggers. | 2016-03-31 |

The end effector assembly includes a pair of opposing jaw members, a knife member, and a driven member. A proximal end of the knife member is selectively engageable to a distal end of the knife drive shaft such that movement of the knife drive shaft moves the knife member. A proximal end of the driven member is configured to operably couple to the jaw drive shaft and a distal end of the driven member is operably coupled to the jaw members to move the jaw members. A coupling member is configured to releasably secure the end effector assembly and the elongated shaft. | 2016-03-31 |
20160089178 | ENDOVASCULAR DEVICES AND METHODS - Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall to at least partially surround the occlusion, and removing at least a portion of the surrounded occlusion from the lumen. | 2016-03-31 |
20160089180 | SURGICAL TOOLS AND SYSTEM FOR SAFELY ACCESSING BODY CAVITIES AND METHODS OF USING THE SAME - The application discloses a set of surgical instruments that may be used to access a human or animal body cavity for medical purposes without causing damage to internal tissues or organs therein, and methods of using the same. The instruments include a safety needle and flexible sheath that may be coupled together and used to establish a minimally invasive method to access a targeted body cavity while preventing or reducing damage to organs or tissues within the targeted cavity. Additional instruments are included within the invention that may be used to establish an access port in the wall of the targeted cavity. That port may be used to introduce catheters or other instruments into the body cavity. It may also be used as a drainage tube for draining or injecting gases and/or fluids from or into the targeted cavity. | 2016-03-31 |
20160089181 | METHODS AND APPARATUS FOR CONTROLLING SURGICAL INSTRUMENTS USING A PORT ASSEMBLY - A surgical port assembly for use with surgical instruments includes a body including an exterior surface and an interior space defined by an interior surface of the body. The surgical port assembly includes a control interface including a plurality of drive members coupled to the body and controllable to apply a force to a different portion of a shaft of an surgical instrument, when the shaft is disposed within the interior space, to move a distal portion of the surgical instrument to a desired position within a body cavity. | 2016-03-31 |
20160089182 | SURGICAL STABILIZER AND CLOSURE SYSTEM - A system for stabilizing the heart via a helical needle, providing access to the interior of the heart via an introducer sheath, and forming a purse string suture using suture delivered by the helical needle. A helical needle projects distally from the device in a helical shape and terminates in a sharp distal tip. The helical needle is advanced into the heart wall, and is used to stabilize the heart and to pass a purse string suture through the heart tissue. An access port provides access to the interior of the heart via an opening passing through the heart wall in an area circumscribed by the helical needle. A length of suture may pass through the helical needle and exit at an opening at or near the needle distal tip. A free end of the length of suture may extend out of the distal tip and back into the hollow suture needle through the opening. The helical needle may have a deflection segment adjacent the distal tip that is more flexible than the rest of the helical distal portion of the helical needle. | 2016-03-31 |
20160089183 | NEEDLE ASSEMBLY WITH RETRACTABLE CUTTING EDGE - The disclosure relates to a needle assembly for delivering a lead and methods of use. The needle assembly is configured to cut tissue and reduce the potential for cutting vulnerable bodily structures. The needle assembly includes an outer needle with a blunt tip and an inner needle with a sharp tip. The outer needle may be curved, and the inner needle may be curved. When the inner needle is rotated with respect to the outer needle, the inner needle protracts or retracts with respect to the outer needle. A stopping feature on the needle assembly may be included to resist over-rotation or over-extension. The needle assembly provides an initial path that may be further dilated for delivering a lead, such as a vagus nerve stimulation lead to a target site. The target site may be electrically tested with some embodiments. | 2016-03-31 |
20160089184 | SURGICAL FLUID MANAGEMENT SYSTEMS AND METHODS - A fluid management system for use with a fluid reservoir includes an inflow pump and an outflow pump. The inflow pump is connectable to a probe for delivering a distention fluid to a body cavity. The outflow pump removes the distention fluid through the same probe, thus establishing a re-circulating volume of distention fluid within the body cavity. The removed fluid is filtered and returned to a fluid reservoir for eventual recycling to the body cavity. A controller adjusts the flow rates of the inflow pump and the outflow pump to maintain a pre-selected fluid pressure or volume within the body cavity. | 2016-03-31 |
20160089185 | CALCULUS RETRIEVING/REMOVING DEVICE AND METHOD - A device for retrieving calculus in a lumen of a living body includes an elongated member possessing an outer dimension configured to be positioned in the lumen of the living body, wherein the tubular body includes an inlet, an outlet and a retrieval space in the interior at a position between the inlet and the outlet. A foldable sealing member is positioned in the tubular body interior and is axially movable in distal and proximal directions, and a plunger is connected to the sealing member so that axial movement of the plunger axially moves the sealing member in the interior of the tubular body. The foldable sealing member is folded into a folded configuration when the plunger is axially moved in a distal direction toward the inlet and being spread out in a spread-out configuration when the plunger is axially moved in a proximal direction away from the inlet. | 2016-03-31 |
