Publication number: 20170100161Abstract: An operator advances a delivery catheter through a guiding catheter, after positioning an inflatable sleeve of the guiding catheter in proximity to a target implant site on an epicardial surface. By inflating the positioned sleeve, the operator displaces the epicardial surface to create a gap that accommodates a reach of the delivery catheter. With the delivery catheter extending distally from the guiding catheter, the operator can activate the reach of the delivery catheter within the gap, and then advance the lead out through a distal-most opening of the delivery catheter. The reach may orient a fixation member of the advanced lead relative to the epicardial surface so the operator can secure the lead to the surface. The sleeve of the guiding catheter is preferably non-compliant and has a maximum diameter of at least twice the reach of the delivery catheter, when inflated.Type: ApplicationFiled: October 8, 2015Publication date: April 13, 2017Inventors: Andrea J. ASLESON, Teresa A. WHITMAN, Kelly M. WIEN

Publication number: 20170100162Abstract: Methods, apparatuses and systems are described for implanting a plurality of fiducial markers into a tissue. Systems include a needle, a stylet sized to slide within a lumen of the needle, and a multi-stop stylet spacer having stopping features configured to engage with the stylet to stop the distal end of the stylet at one or more predetermined distances from the distal end of the needle. Methods for implanting a plurality of fiducial markers into a tissue are described and include inserting a needle preloaded with fiducial markers into a tissue, adjusting a multi-stop stylet spacer from a safety position to a first deployment position, deploying a first fiducial marker into the tissue, adjusting the stylet spacer from the first deployment position to a second deployment position, and deploying a second fiducial marker into the tissue.Type: ApplicationFiled: October 4, 2016Publication date: April 13, 2017Inventors: EUGENE CAMPBELL, JOHN O. MCWEENEY, BRIAN TINKHAM, STEPHEN J. TULLY

Publication number: 20170100164Abstract: In some embodiments, a spinal stabilization system may be formed in a patient using quick-connect sleeve assemblies. Each quick-connect sleeve assembly can be coupled to a bone fastener assembly in a fast and intuitive way. In one embodiment, a quick-connect sleeve assembly has a detachable member and a movable member. Both members engage a collar of the bone fastener assembly. In one embodiment, the engagement can be locked via one or more locking features to facilitate screwing a bone fastener of the bone fastener assembly onto a vertebral body in a minimally invasive surgical procedure. Each quick-connect sleeve assembly has a low profile and is particularly shaped for minimally invasive entry.Type: ApplicationFiled: December 21, 2016Publication date: April 13, 2017Inventors: Michael E. Landry, Larry T. Khoo, Charles R. Forton, Brian Bergeron, Bruce A. Riceman, Peter Thomas Miller, Kameron Scott Ely
