1233 results about "Less invasive surgery" patented technology

Minimally invasive surgery is any type of surgery which requires less invasive techniques than those used in traditional surgery. A classic example is laparoscopic surgery, a type of surgery which is performed with the use of keyhole incisions and special instruments, allowing a surgeon to work without creating...

Means and method of replacing a heart valve in a minimally invasive manner

A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners, two at a time to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners. Drawstrings are operated from outside the patient's body and cinch the sewing cuff to the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. At least two rows of staggered fasteners are formed whereby fasteners are located continuously throughout the entire circumference of the cuff. A minimally invasive surgical method is disclosed, and a method and tool are disclosed for repairing abdominal aortic aneurysms in a minimally invasive manner.

Means and method of replacing a heart valve in a minimally invasive manner

A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners and is self-contained whereby a fastener is delivered and placed all from inside a vessel. The fasteners are self-forming whereby they do not need an anvil to be formed. Anchor elements are operated from outside the patient's body to cinch a prosthesis to an anchoring cuff of the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. Fasteners are placed and formed whereby fasteners are located continuously throughout the entire circumference of the cuff. A minimally invasive surgical method is disclosed, and a method and tool are disclosed for repairing abdominal aortic aneurysms in a minimally invasive manner. Fasteners that are permanently deformed during the process of attaching the cuff are disclosed as are fasteners that are not permanently deformed during the attaching process.

Cardiac tissue ablation instrument with flexible wrist

InactiveUS20060199999A1Promotes convenient, simplified manufacturing and assembly processesShorten the counting processEndoscopesSurgical manipulatorsWristInstrumentation
An articulate minimally invasive surgical instrument with a flexible wrist to facilitate the safe placement and provide visual verification of the ablation catheter or other devices in Cardiac Tissue Ablation (CTA) treatments is described. In one embodiment, the instrument is an endoscope which has an elongate shaft, a flexible wrist at the working end of the shaft, and a vision scope lens at the tip of the flexible wrist. The flexible wrist has at least one degree of freedom to provide the desired articulation. It is actuated and controlled by a drive mechanism located in the housing at the distal end of the shaft. The articulation of the endoscope allows images of hard-to-see places to be taken for use in assisting the placement of the ablation catheter on the desired cardiac tissue. The endoscope may further include couplings to releasably attach an ablation device / catheter or a catheter guide to the endoscope thereby further utilizing the endoscope articulation to facilitate placement of the ablation catheter on hard-to-reach cardiac tissues. In another embodiment, the articulate instrument is a grasper or any other instrument with a flexible wrist and a built-in lumen to allow an endoscope to insert and be guided to the distal end of the instrument.

Surgically implantable knee prothesis

A self-centering meniscal prosthesis device suitable for minimally invasive, surgical implantation into the cavity between a femoral condyle and the corresponding tibial plateau is composed of a hard, high modulus material shaped such that the contour of the device and the natural articulation of the knee exerts a restoring force on the free-floating device.

Device to permit offpump beating heart coronary bypass surgery

A heart retractor links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the heart retractor of the present invention. The retractor includes a plurality of flexible arms and a plurality of rigid arms as well as a surgery target immobilizing element. One form of the retractor can be used in minimally invasive surgery, while other forms of the retractor can accommodate variations in heart size and paracardial spacing.

Interactive user interfaces for robotic minimally invasive surgical systems

In one embodiment of the invention, a method for a minimally invasive surgical system is disclosed. The method includes capturing and displaying camera images of a surgical site on at least one display device at a surgeon console; switching out of a following mode and into a masters-as-mice (MaM) mode; overlaying a graphical user interface (GUI) including an interactive graphical object onto the camera images; and rendering a pointer within the camera images for user interactive control. In the following mode, the input devices of the surgeon console may couple motion into surgical instruments. In the MaM mode, the input devices interact with the GUI and interactive graphical objects. The pointer is manipulated in three dimensions by input devices having at least three degrees of freedom. Interactive graphical objects are related to physical objects in the surgical site or a function thereof and are manipulatable by the input devices.
