摘要:
An end-side anastomosis system including a fitting including a base for attachment to a graft, the base be configured to form a seal with an opening in a host vessel wall a leading petal having a cross-section with a radius of curvature approximating a radius of curvature of the host vessel, the leading petal being configured to dilate the host vessel wall opening while advancing the fitting through the opening and a rear petal, the rear petal being deflectable to be advanced through the host vessel opening.
摘要:
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.
摘要:
Devices for supporting diagnostic or therapeutic elements and assemblies for creating curves in the distal regions thereof. The assemblies are adapted to create compound curves such that respective portions of the distal region have distinct curvatures.
摘要:
Systems and associated methods place a temperature sensing element in an “edge regions” between an energy transmitting electrode and a non-electrically conducting support body, where higher temperatures are likely to exist. Reliable temperature sensing, which is sensitive to variations in temperatures along the electrode, results.
摘要:
A surgical method and apparatus for positioning a diagnostic or therapeutic element within the body. The apparatus may be catheter-based or a probe including a relatively short shaft.
摘要:
Compound steering assemblies, usable in both diagnostic and therapeutic applications, enable a physician to swiftly and accurately steer the distal section of the catheter in multiple planes or complex curves to position and maintain ablation and/or mapping electrodes in intimate contact with an interior body surface.
摘要:
A sutureless anastomosis systems for securing a bypass graft to a host vessel or other tubular structure including a bypass graft and fitting. A compression mechanism may be used with the system for attachment of the bypass graft to the fitting. An electrode is connected to the fitting and an energy source. The energy source transmits energy to the electrode and causes the adjacent tissue to rise in temperature and bond to a vessel or fitting.
摘要:
Devices for insertion into an atrial appendage of stasis reducing components such as mesh members, chemical bonding agents or expandable anchors are disclosed.
摘要:
Systems and associated methods position arrays of multiple emitters of ablating energy in straight or curvilinear positions in contact with tissue to form elongated lesion patterns. The elongated lesion patterns can continuous or interrupted, depending upon the orientation of the energy emitters.
