Publication number: 20190223819Abstract: For non-invasive EP mapping, a sparse number of electrodes (e.g., 10 in a typical 12-lead ECG exam setting) are used to generate an EP map without requiring preoperative 3D image data (e.g. MR or CT). An imager (e.g., a depth camera) captures the surface of the patient and may be used to localize electrodes in any positioning on the patient. Two-dimensional (2D) x-rays, which are commonly available, and the surface of the patient are used to segment the heart of the patient. The EP map is then generated from the surface, heart segmentation, and measurements from the electrodes.Type: ApplicationFiled: January 24, 2018Publication date: July 25, 2019Inventors: Tommaso Mansi, Tiziano Passerini, Puneet Sharma, Terrence Chen, Ahmet Tuysuzoglu, Shun Miao, Alexander Brost

Publication number: 20190223860Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose on a first portion of at least a first limb and has a second portion connected to the filament engagement feature of the anchor. Preferably, at least one free filament limb, which in some embodiments is a length of the first filament and in other embodiments is a second filament, is capable of being passed through tissue to be repaired and has at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone. The noose strangulates the free filament limb when tension is applied to at least one of the free filament limb and the noose.Type: ApplicationFiled: April 2, 2019Publication date: July 25, 2019Inventors: Mehmet Ziya Sengun, Howard C.

Publication number: 20190223861Abstract: A suture anchor assembly includes a main suture strand, a plurality of suture arms, and a plurality of suture anchor elements connected to the main suture strand by a suture arm. The suture anchor elements are configured to rest against a cortex of a bone to provide an anchor when they are in a deployed configuration. The suture anchor assemblies can be employed in place of or in addition to traditional suture anchors. The assemblies, kits, and methods described herein can be utilized in a variety of procedures and locations in the body where anchoring a graft or tissue adjacent a bone is desired, including, for example, rotator cuff repair and ligament (e.g., the anterior cruciate ligament or ACL) reconstruction and/or repair.Type: ApplicationFiled: April 3, 2019Publication date: July 25, 2019Inventors: David B.

Publication number: 20190223862Abstract: An endoscopic stitching device includes an actuation shaft, a tool assembly, and a drive assembly. The tool assembly includes a suture needle and a pair of jaws transitionable between open and closed positions. Each jaw includes a needle engaging blade slidably supported thereon. Each needle engaging blade is transitionable between an extended position in which the needle engaging blade engages the suture needle and a retracted position in which the needle engaging blade is disengaged from the suture needle. The drive assembly includes first, second, and third electrical actuators. The first actuator is operatively coupled with the actuation shaft to cause axial displacement of the actuation shaft. The axial displacement of the actuation shaft causes opening and closing of the pair of jaws. The second and third actuators are operatively coupled with the needle engaging blades to provide axial displacement of the needle engaging blades.Type: ApplicationFiled: April 2, 2019Publication date: July 25, 2019Inventors: Stanislaw Marczyk, Russell Pribanic, Anthony Calderoni, Christopher Switalski

Publication number: 20190223863Abstract: The suture passer includes a body from which two mechanisms protrude: a hollow needle through which a suture is guided, the suture exiting at the surgical site; and a sliding hollowing tube with a distal opening, exposing a resilient member. When gripping of a suture is required, the resilient member is intentionally over-extended, causing the resilient member to bow and protrude from the distal opening. A suture is then passed into the resulting gap between the sliding hollowing tube and resilient member, the resilient member then allowed to retract back into place, thereby clamping the suture.Type: ApplicationFiled: October 23, 2018Publication date: July 25, 2019Inventor: Yasser Nadim

Publication number: 20190223864Abstract: A surgical retractor device holds back underlying tissue from a tissue wall when suturing through the tissue wall with a suture passer. The retractor device comprises a barrier material having an upper barrier surface for spanning between the tissue wall and the underlying tissue and which is resistant to being punctured by the suture passer. The barrier material is operable between a working position in which the upper barrier surface occupies a first prescribed area and can be positioned between the tissue wall and the underlying tissue, and a collapsed position in which the barrier material is manipulated relative to the working position such that the upper barrier surface occupies a second prescribed area that is less than the first prescribed area such that the barrier material can pass through an incision in the tissue wall.Type: ApplicationFiled: October 16, 2017Publication date: July 25, 2019Inventor: Yigang Luo

Publication number: 20190223865Abstract: A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.Type: ApplicationFiled: March 5, 2019Publication date: July 25, 2019Inventors: Frederick E. Shelton, IV, Chester O. Baxter, III

Publication number: 20190223866Abstract: A surgical instrument comprising a handle assembly, an elongated portion, a head portion, an approximation mechanism, and a lockout mechanism is disclosed. The handle assembly comprises a movable handle and a stationary handle. The elongated portion extends distally from the handle assembly and defines a longitudinal axis. The head portion is disposed adjacent a distal portion of the elongated portion, and comprises a first jaw member and a second jaw member. The approximation mechanism comprises a drive member disposed in mechanical cooperation with the first jaw member and is configured to longitudinally move the first jaw member in relation to the second jaw member. The lockout mechanism is configured to selectively permit actuation of the movable handle to eject fasteners from the second jaw member. The lockout mechanism comprises a pin extending from the movable handle and is slidingly engaged with a slot in the drive member.Type: ApplicationFiled: April 2, 2019Publication date: July 25, 2019Inventors: Stone Shi, Qianhong Yang, Shunhong Xu
