摘要:
A tissue penetrating catheter that is usable to advance a tissue penetrator from within a blood vessel, through the wall of the blood vessel to a target location. The catheter includes at least one stabilizing device thereon for stabilizing catheter prior to advancing the tissue penetrator. The tissue penetrator may extend through a lumen in the body of the catheter and project transversely through an exit port. The stabilizing device may be located closely adjacent to the exit port, or may surround the exit port. The stabilizing device may be one or more balloons, or other mechanical structure that is expandable into contact with the inner luminal wall of the blood vessel. Desirably, the exit port is forced into contact with the blood vessel wall to shorten the distance that the tissue penetrator projects from the catheter body to the target location. The catheter is particular useful for forming blood flow tracts between blood vessels, in particular in coronary revascularization procedures. Methods of utilizing such a catheter to bypass an arterial obstruction is also disclosed.

摘要:
A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.
摘要:
A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant anchor devices for such purposes.
摘要:
Anatomical models representing one or more anatomical structures of a human or non-human animal and related methods for demonstrating, training, promotion and sale of medical, cosmetic and surgical products or procedures. A working device is inserted into the anatomical model and used to perform a simulated procedure, thereby causing an indicator apparatus (e.g., a removable business card) to become perceptibly altered. The indicator apparatus may then be removed and provided a potential user, consumer or purchaser of the medical, surgical or cosmetic product.
摘要:
Tools, devices and methods for treating a patient. An incision or puncture is made though the patient's skin and a delivery tract is made through an opening formed by the incision or puncture, subcutaneous fat and fascia, far into the patient's abdominal cavity. A guide member is inserted through the delivery tract and a distal end portion of the guide member is positioned at a target location within the abdominal cavity. An implantable device is delivered with the aid of the guide member, and the implantable device is attached to at least one internal body structure. A fillable member of the implantable device is at least partially filled with fluid. The guide member is removed and an adjustment member is attached to a conduit in fluid communication with the fillable member. The attachment member is anchored to an internal body structure and the incision or puncture is closed.
摘要:
Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).

Methods and apparatus for treating disorders of the ear, nose, throat or paranasal sinuses, including methods and apparatus for dilating ostia, passageways and other anatomical structures, endoscopic methods and apparatus for endoscopic visualization of structures within the ear, nose, throat or paranasal sinuses, navigation devices for use in conjunction with image guidance or navigation system and hand held devices having pistol type grips and other handpieces.
摘要:
A system for manipulating energy transferred by members defining a joint. The system includes a first attachment structure configured to be attached to a first member of the joint and a second attachment structure configured to be attached to a second member of the joint. There is also an adjustable energy absorbing device attached to the first attachment structure and second attachment structure, wherein adjusting the energy absorbing device changes the load manipulating characteristics of the energy absorbing device.
