摘要:
A surgical apparatus including an energy transmission probe, having a flexible support member and at least one energy transmission device, and a coupling device including a base member adapted to be removably secured to a first portion of the flexible support member and an engagement device connected to the base member and adapted to be removably secured to a second portion of the flexible support member.

A catheter assembly having a sheath, which includes a side wall enclosing an interior bore, and a distal region. The assembly also has a bendable catheter tube, which is carried for sliding movement in the interior bore. A pull wire also runs through the interior bore of the sheath, preferably within a lumen. The catheter tube has a distal portion with a coupling which joins the distal portion of the catheter tube and the distal portion of the pull wire. Relative movement of the pull wire and the sheath causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.

A catheter device for inserting a tightened lasso of material into a body by remote control includes a removable end component which provides ratchet-like tightening but prevents loosening of the lasso.
摘要:
Enhanced electrical connections for electrodes are provided. In one implementation, an electrode body comprises a first electrically nonconductive layer and a second electrically nonconductive layer overlying at least a portion of the first layer. An intermediate region is formed between the first and second layers. An electrically conductive pathway extends within the intermediate region. An formed opening extends to the intermediate region, exposing a part of the electrically conductive pathway. An electrically conductive material is deposited on the second layer so that a part of the electrically conductive material passes through the opening to establish electrical contact between the electrically conductive material and the electrically conductive pathway.

An embodiment of the invention includes a surgical device for passing suture through soft tissue. The surgical device can include at least one elongate superelastic member having a thickness and having a first resting configuration that defines at least one curve having a first radius of curvature greater than or equal to 3 times the thickness of the superelastic member. The surgical device also can include a thermally formed opening in the superelastic member, the opening adapted to receive at least one strand of suture. Moreover, the surgical device can include a superelastic member adapted to be straightened into a second configuration having a second radius of curvature larger than the first radius of curvature.
摘要:
The present invention provides ultrasound-guided ablation catheters and methods for their use. In one embodiment, a tissue ablation apparatus (2) includes a flexible elongate body (12) having proximal (14) and distal (12) ends. A plurality of spaced-apart electrodes (24) are operably attached to the flexible body near the distal end. A plurality of transducer elements (28) are disposed between at least some of the electrodes. Transducers assist the physician in determining whether or not the ablation elements are in contact with the tissue to be ablated.

Described are shoes, orthodic appliances, and anatomic braces containing superelastic support members for enhanced performance. The superelastic supports provide dynamic response to deflection. As such, the superelastic supports incorporated in the soles of shoes enhance walking, running, jumping, kicking, or other motion involving the foot. The superelastic supports may be incorporated in the body of shoes to reinforce the ankle joint. The embodiments of the invention also provide superelastic supports in braces to reinforce or stabilize the knees, ankles, elbows, wrists, shoulders, back, neck, hips, or other anatomy commonly associated with a degree of twisting, rotation, bending, or other desired motion. The braces also intensify the motion of anatomic structures, apply a specific resistance at the joint to strengthen the muscles during training or rehabilitation, and/or immobilize or stabilize joints, bones, or other anatomic structures during healing of an injury.
摘要:
A bypass graft incorporates fixation mechanisms at its opposite ends, for securing these ends to different locations along a blood vessel, or alternatively to different locations wherein one of the locations is a different vessel or an organ defining a cavity. Mechanical fixation features such as collets or grommets can be employed, enhanced by delivery of an electrical current sufficient to heat surrounding tissue to form a thermal bond. A graft deployment system includes a tissue dilator and a needle for perforating tissue, mounted coaxially within the dilator. Intralumenal systems further include a catheter for containing the dilator.
摘要:
An interface is associated with a structure which, in use, is deployed in an interior body region of a patient. The structure includes an operative element coupled to a controller, which establishes an operating condition for the operative element to perform a diagnostic or therapeutic procedure in the interior body region. The interface generates a first display comprising an image of the structure at least partially while the operative element performs the procedure. The interface also generates a second display comprising one or more data fields reflecting the operating condition of the controller. The interface enables selection of the first display or the second display for viewing on a display screen.
