Patent number: 10265062Abstract: A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.Type: GrantFiled: February 28, 2014Date of Patent: April 23, 2019Assignee: ArthroCare CorporationInventors: Seth A. Foerster, Thomas Weisel, Roger Pisarnwongs

Patent number: 10195042Abstract: A shoulder implant device includes one or more fixation features including an acromial intrusion element and an inflatable humeral balloon portion that receives a fluid through the acromial intrusion element. The intrusion element comprises a valve that can receive multiple needle sticks to add or remove fluid to or from the inflatable humeral balloon. The device is implanted in a subacromial space such that the one or more fixation features at least secure the device to the acromion and the inflatable balloon portion rests against the proximal end of the corresponding humerus. Fluid in the balloon portion maintains separation of the acromion and the humerus to reduce or prevent impingement.Type: GrantFiled: October 6, 2017Date of Patent: February 5, 2019Assignee: Microaire Surgical Instruments LLCInventors: Ryan Vanleeuwen, Shannon Vaughn, Thomas Weisel

Patent number: 10166020Abstract: Devices and methods are disclosed herein for accessing the hip joint. A first device can be securely attached to the capsule of a joint. The first device can tent the capsule to increase the volume of the peripheral compartment. A second device can be biased against the first device to pierce the tented capsule and create a portal. Devices and methods are also disclosed herein for distending the capsule of a joint. A distention device may access a portal established within the capsule. The distention device can expand the capsule by applying an expansive force within the peripheral compartment. The distention device can maintain distention of the peripheral compartment while other devices access the joint.Type: GrantFiled: June 13, 2017Date of Patent: January 1, 2019Assignee: Pivot Medical, Inc.Inventors: Thomas Weisel, Geoff Willis, James Flom, Hanson S.
