Patent number: 10194893Abstract: A medical device may include a stabilizer configured to be coupled to a port of an insertion device. The medical device may further include a shaft configured for telescopic translation within the stabilizer and a grip coupled to the shaft. Further, the medical device may include an actuator coupled to the grip. The actuator may be axially moveable relative to the grip so as to selectively actuate a distal assembly of the medical device.Type: GrantFiled: September 24, 2015Date of Patent: February 5, 2019Assignee: BostonScientific Scimed, Inc.Inventor: Aaron Kirkemo

Patent number: 10194894Abstract: A specimen retrieval device includes an applicator. A specimen retrieval pouch is operably disposed within the applicator and deployable therefrom. The specimen retrieval pouch defines a longitudinal axis therethrough and includes a closed bottom portion and an open upper portion. The closed bottom portion includes a plurality of spikes configured to grasp a specimen positioned within the confines closed bottom portion. The upper closed portion includes one or more axial folds that are movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch.Type: GrantFiled: September 22, 2016Date of Patent: February 5, 2019Assignee: Covidien LPInventors: Dmitri Menn, Gene A. Stellon

Patent number: 10194895Abstract: A method of forming an access opening through a psoas muscle to a patient's spine includes laterally inserting a stimulating dilator into the psoas muscle. The stimulating dilator has a stimulation channel formed in an outer surface thereof. An electrical pulse is transmitted into the stimulating dilator to locate a position of a nerve in the patient's psoas muscle. The stimulating dilator is laterally inserted through the psoas muscle and toward the patient's spine in a way that avoids the nerve. A stimulating probe is inserted into the stimulation channel along the outer surface of the stimulating dilator while transmitting an electrical pulse into the stimulating probe to verify the position of the nerve.Type: GrantFiled: April 27, 2018Date of Patent: February 5, 2019Assignee: DePuy Synhes Products, Inc.Inventors: Peter Fatone, Brandon Randall

Patent number: 10194896Abstract: A retractor system is provided having a plurality of blade portions that collectively present a low profile tapered configuration for insertion through tissue along a natural tissue plane. Once inserted through tissue the blade portions may be independently moved apart to form an access path to a surgical site, such as by first moving the blade portions apart along the natural tissue plane followed by moving the blade portions apart transverse to the natural tissue plane. The blade portions may be attached to retractor frame members, and rack and pinion frame components may be used to control movement of the blade portions relative to one another. Pins may be used to secure the blade portions to bone.Type: GrantFiled: November 3, 2015Date of Patent: February 5, 2019Inventor: Gordon D. Donald

Patent number: 10194899Abstract: Surgical methods for stabilizing a joint are disclosed. The methods aid in surgical repairs by allowing for quick and reproducible repairs to be made. A bone tunnel is formed anteriorly/posteriorly in clavicle, and a bone tunnel is formed superiorly in acromion. At least one cannulated insert is provided into one or both of bone tunnels to protect the bone from abrasions caused by a flexible construct. A flexible construct is passed through the acromion tunnel and the clavicle tunnel. An attachment device may then be positioned on at least one side of the clavicle and/or acromion tunnel, and the flexible construct is attached to the attachment device.Type: GrantFiled: October 28, 2015Date of Patent: February 5, 2019Assignee: Arthrex, Inc.Inventors: William C. Benavitz, Allen E. Holowecky, Augustus D. Mazzocca, Eugene M. Wolf, James J. Guerra
