摘要:
The present invention provides devices and methods for attachment of an endolumenal gastrointestinal device, such as an artificial stoma device, a gastrointestinal bypass sleeve or other therapeutic or diagnostic device, within a patient's digestive tract. In one application of the invention, an endolumenal bypass sleeve is removeably attached in the vicinity of the gastroesophageal junction to treat obesity and/or its comorbidities, such as diabetes. The bypass sleeve may be at least partially deployed by eversion.

Aspects of this invention disclose devices and methods for attachment of a gastrointestinal sleeve. In some embodiments, the attachment device comprises a flexible cuff, a gastrointestinal sleeve interface, and a gastrointestinal sleeve. Some aspects of the invention contemplate the use of T-tags for attachment of the cuff to tissue. In some aspects of the invention, attachment of the sleeve to the cuff is achieved using various fasteners.
摘要:
Apparatus and methods are described for treatment of morbid obesity using minimally invasive techniques. The apparatus includes a system of components that may be used separately or in combination for effectively reducing stomach volume, bypassing a portion of the stomach and/or small intestines, reducing nutrient absorption in the stomach and/or small intestines and/or depositing minimally or undigested food farther than normal into the intestines, thereby stimulating intestinal responses. The components described include an artificial stoma device, a gastric sleeve device, an intestinal sleeve device and a combined gastrointestinal sleeve device.
摘要:
A method of acquiring and mapping physiological data in a heart chamber includes inserting a catheter into the heart chamber. Physiological data in the heart chamber is acquired with the catheter. The position of the catheter is determined, and the location of the acquired physiological data is determined using the position of the catheter. Information related to the three-dimensional geometry of at least a portion of the heart chamber is received, and a three-dimensional map of the physiological data is created and superimposed on a geometrical representation of the three-dimensional geometry information.

摘要:
One or more curved axial bore is formed commencing from an anterior or posterior sacral target point and cephalad through vertebral bodies in general alignment with a visualized, trans-sacral axial instrumentation/fusion (TASIF) line in a minimally invasive, low trauma, manner. An anterior axial instrumentation/fusion line (AAIFL) or a posterior axial instrumentation/fusion line (PAIFL) that extends from the anterior or posterior target point, respectively, in the cephalad direction following the spinal curvature through one or more vertebral body is visualized by radiographic or fluoroscopic equipment. Generally curved anterior or posterior TASIF axial bores are formed in axial or parallel or diverging alignment with the visualized AAIFL or PAIFL, respectively. The anterior and posterior TASIF axial bore forming tools can be manipulated from proximal portions thereof to adjust the curvature of the anterior or posterior TASIF axial bores as they are formed in the cephalad direction. The boring angle of the distally disposed boring member or drill bit can be adjusted such that selected sections of the generally curved anterior or posterior TASIF axial bores can be made straight or relatively straight, and other sections thereof can be made curved to optimally traverse vertebral bodies and intervening disc, if present.

An apparatus to establish access into the uterus and the fallopian tubes of a female for diagnostic or therapeutic procedures includes a cervical access catheter, an ostial access catheter insertable through the cervical access catheter, and a fallopian access catheter insertable through the ostial access catheter. The cervical access catheter incorporates a distally located intrauterine balloon which is inflatable after insertion into the uterus. The cervical access catheter also incorporates a cervical retention disk which can be slid into position against the anterior lip of the cervix to anchor the cervical access catheter into the cervical canal between the intrauterine balloon and the cervical disk. Once the cervical access catheter is properly anchored, the ostial access catheter is inserted through the cervical access catheter. The ostial access catheter has a guidable distal portion which, after the distal portion has passed through the cervical access catheter, can be positioned into the ostium of the fallopian tube. If desired, a contrast media can then be injected through the ostial access catheter. Further, if additional information is required, the fallopian access catheter can be inserted through the ostial access catheter and advanced into the fallopian tube for injection of a contrast media directly into the fallopian tube.

A mapping catheter assembly 10 including a flexible lead body 12 and a deformable lead body 14. A lumen 22 is provided to accept a reference catheter 18 which includes a distal tip electrode assembly 29. In use an array 16 of electrode sites are deformed into a spherical shape after the assembly is placed in a heart chamber. The reference electrode assembly 29 is advanced into contact with the heart wall to provide calibration information for the array 16.
