The posts may extend from the base in parallel planes, and each of the posts may define a plurality of channels passing through its width. The channels may be so oriented that, for each post (a) the channels define suture needle guide paths in one or more planes, and (b) at least one channel is not perpendicular to a long axis of the first flanking post, so that it defines an oblique suture needle guide path. The tissue guard may be connected to the base by a connector so adjustable as to control spacing between the posts and the tissue guard.Type: ApplicationFiled: November 30, 2016Publication date: July 13, 2017Inventor: Jonathan T.

Publication number: 20170196553Abstract: A suture clip includes a body having a proximal end, a distal end, and a sidewall defining a lumen through the body from the proximal end to the distal end. At least one engaging arm is movable between a loaded condition in which the engaging arm is oriented substantially parallel with the sidewall of the body, and a relaxed condition in which the engaging arm is oriented transversely to the sidewall of the body and at least partially disposed within the lumen.Type: ApplicationFiled: January 9, 2017Publication date: July 13, 2017Applicant: St. Jude Medical, Cardiology Division, Inc.Inventor: Theodore Paul Dale

Publication number: 20170196554Abstract: A device is disclosed for the securement of dermal tissues. The device provides approximation and eversion of the tissue as well as the placement of a fixation element that bridges a wound. The fixation element may be produced in several fixed or dynamic configurations that may or may not alter the ability to engage tissue in response to stresses placed upon the fixation member post-deployment. The delivery device inserts the fastener percutaneously through the epidermis into the sub-dermal position without entering the wound margins with any part of the approximation portion of the delivery device.Type: ApplicationFiled: January 11, 2016Publication date: July 13, 2017Inventors: Robert A. Rousseau, David C. Lindh, SR.

Publication number: 20170196555Abstract: A suture package for retaining a barbed suture is provided. The suture package includes a suture retaining member including an outer wall and an inner wall. The inner wall is radially spaced from the outer wall and defines a suture retaining area therebetween. The inner wall defines a needle retaining area and includes at least one opening therein to permit reception of at least one suture therethrough. The outer wall includes a plurality of inwardly extending tabs configured to engage a cover. The suture package further includes a cover configured to be received within the outer wall of the suture retaining member and to selectively engage the inwardly extending tabs formed thereon.Type: ApplicationFiled: March 28, 2017Publication date: July 13, 2017Inventors: David Kirsch, Guido Pedros

Publication number: 20170196557Abstract: An adapter assembly includes an elongated body, a circuit assembly, and an annular member. The elongated body includes a proximal portion configured to couple to a handle assembly, and a distal portion configured to couple to a surgical loading unit. The circuit assembly is disposed within the distal portion of the elongated body and configured to be in communication with a handle assembly. The annular member is rotatably disposed within the distal portion of the elongated body and includes an electrical contact. The annular member is rotatable between a first orientation, in which the electrical contact of the annular member is electrically isolated from the circuit assembly, and a second orientation, in which the electrical contact of the annular member is electrically connected to the circuit assembly.Type: ApplicationFiled: December 14, 2016Publication date: July 13, 2017Inventors: Matthew Chowaniec, David Chowaniec

Publication number: 20170196558Abstract: The present invention is directed to a surgical instrument with a robotics system, a memory device and an end effector having an elongate channel, knife position sensor(s) and a firing bar coupled to a knife. In response to drive motions initiated by the robotics system, the firing bar may translate within the elongate channel. As the firing bar translates, the sensor(s) transmit a signal to the memory device. The position of the knife may be determined from the output signals and may be communicated to the robotics system or instrument user. The sensors may be Hall Effect sensors.Type: ApplicationFiled: March 20, 2017Publication date: July 13, 2017Inventors: Jerome R. Morgan, Frederick E. Shelton, IV
