Patent number: 9119654Abstract: Surgical methods and devices allow closed-chest surgery to be performed on a heart of a patient while the heart is beating. A region of the heart is stabilized by engaging a surface of the heart with a stabilizer without having to stop the heart. Motion of the target tissues is inhibited sufficiently to treat the target tissues with robotic surgical tools which move in response to inputs of a robotic system operator. A stabilizing surface of the stabilizer is coupled to a drive system to position the surface from outside the patient, preferably by actuators of the robotic servomechanism. Exemplary stabilizers includes a suture or other flexible tension member spanning between a pair of jointed bodies, allowing the member to occlude a coronary blood vessel and/or help stabilize the target region between the stabilizing surfaces.Type: GrantFiled: January 13, 2012Date of Patent: September 1, 2015Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Andris D. Ramans, David J. Rosa, Volkmar Falk

Patent number: 9113939Abstract: Surgical tools that can be used in single port laparoscopic procedures can include a low-profile handle assembly to minimize tool interference adjacent the incision site. For example, a handle assembly for a surgical instrument can have a generally in-line configuration extending linearly along a central longitudinal axis of an elongate shaft of the instrument. A linkage mechanism including a trigger, an actuation link, and an actuation shaft can be positioned within the in-line handle. The linkage mechanism can be pivoted between an open position in which end effectors of the instrument are open and a toggle position in which the end effectors are locked closed. A locking mechanism such as a ratchet mechanism can also be used to lock the end effectors. A surgical dissector can include gripping jaws having a curved profile or an angled elongate shaft to minimize tool interference and maximize visibility within a procedure site.Type: GrantFiled: October 11, 2010Date of Patent: August 25, 2015Assignee: Applied Medical Resources CorporationInventors: Arkadiusz A.

Patent number: 9107734Abstract: An embolic protection device for use in a patient's blood vessel, such as the aorta, has an approximately cylindrical outer structure made of a filter mesh material and an approximately conical inner structure also made of a filter mesh material. On the downstream end of the embolic protection device, the wider end of the conical inner structure is joined to the cylindrical outer structure. The upstream end of the embolic protection device is open for blood to flow between the conical inner structure and the cylindrical outer structure. The space between the conical inner structure and the cylindrical outer structure defines a collection chamber for captured emboli. The narrow upstream end of the conical inner structure has a catheter port with a resilient seal that is sized for passage of a catheter shaft. The filter mesh material may be self-supporting or it may be supported on a resilient-framework or an inflatable framework.Type: GrantFiled: November 29, 2007Date of Patent: August 18, 2015Assignee: EMBOLINE, INC.Inventor: Amir Belson

Patent number: 9101739Abstract: An inflation device includes a syringe body containing a bore. The bore holds a fluid that is used to inflate a separate device such as a dilation balloon. A plunger assembly slides within the syringe bore and contains a sealing member that forms a fluid tight seal with the syringe body. A shut-off valve is disposed within the distal end of the syringe body. The distal end of the syringe body has a fluid bypass channel fluidically coupled to the aperture of a connector. The shut-off valve has a spring-biased moveable piston with a bypass lumen contained therein, wherein the bypass lumen forms a fluid path between the bore and the fluid bypass channel when the pressure of the fluid is below a threshold value. The fluid path between the bore and the fluid bypass channel is interrupted when the pressure of the fluid is above the threshold value.Type: GrantFiled: February 17, 2009Date of Patent: August 11, 2015Assignee: ENTELLUS MEDICAL, INC.Inventors: Paul R.

Patent number: 9095674Abstract: A nose clip includes an outer support member adapted to contact an outside surface of a nose. A bridge connected at a first end to the outer support member; and an inner support member connected to a second end of the bridge and adapted to be inserted into the nostril and to contact an inner surface of the nostril. When inserted, tension generated between the outer support member and the inner support member causes lateral movement of a surface within the nostril and opens a nasal airway. Additionally, the inner support can be curved to create an outward movement of the lateral wall of the nose. This in turn enables improved breathing.Type: GrantFiled: August 10, 2009Date of Patent: August 4, 2015Inventor: Dean M. Toriumi

Patent number: 9084623Abstract: To perform a tool exchange in a medical robotic system, tool is retracted back into an entry guide from a deployed position and pose so that an assistant in the operating room may replace it with a different tool. While the tool is being retracted back towards the entry guide by user action, its configuration is changed to an entry pose while avoiding collisions with other objects so that it may fit in the entry guide. After the tool exchange is completed, a new tool is inserted in the entry guide and extended out of the guide by user action to the original position of the old tool prior to its retraction into the entry guide while the tool's controller assists the user by reconfiguring the new tool so as to resemble the original deployed pose of the old tool prior to its retraction into the entry guide.Type: GrantFiled: November 5, 2009Date of Patent: July 21, 2015Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Daniel Gomez, Nicola Diolaiti, David Q.

Patent number: 9044221Abstract: Improved methods and apparatuses for heart valve repair in a beating heart of a patient utilize an exchangeable heart valve repair system. Heart valve repair system can include a port adapted to be seated in the heart wall and an imaging catheter slidable within the port. The imaging catheter can be selectively locked relative to the port for insertion into the heart and unlocked once the port is seated to allow the imaging catheter to move distally towards target tissue. A deployment catheter slidably disposed in the imaging catheter and a repair cartridge slidably disposed in the deployment catheter can be used to capture the target tissue and deploy a repair device into the tissue after proper capture is confirmed. System elements can be selectively removed from and replaced within port to deploy additional repair devices while port maintains a seal while elements are and are not inserted.Type: GrantFiled: December 29, 2011Date of Patent: June 2, 2015Assignee: NeoChord, Inc.Inventors: John Zentgraf, David Joseph Parins, Arun Saini
