摘要:
Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems and ingestible pills. In one embodiment, a method of producing satiety comprising the steps of accessing a gastrointestinal tract of a patient and implanting an intraintestinal therapeutic substance eluting implant. The implant is capable of eluting a satiety inducing substance selected from at least one of a nutrient, a specific satiety inducing bio-active substance, pancreatic polypeptides, free fatty acids, cholecystokinin, amino acids, glutamine, lipids, linoleic acid, or a combination thereof, from the implant into the gastrointestinal tract.

The present invention relates to an anastomotic device (10) comprising a first ring (20) having a first contact surface (21) and a second ring (30) having a second contact surface (31). The rings (20, 30) are suitable to be approached in the axial direction (X) such as to move said contact surfaces (21; 31) towards each other. The anastomotic device is characterized in that the contact surfaces (21, 31) have an undulated shape relative to a plane (π) perpendicular to the axis (X) of the rings (20, 30). According to another aspect thereof, the invention also relates to an apparatus (60) for the implantation of the anastomotic device (10). According to a further aspect thereof, the invention relates to a kit comprising an anastomotic device (10) and an apparatus (60) for the implantation of the same.

Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems, and ingestible pills. In one embodiment, the implantable system comprises a device delivering a therapeutic substance to a target location within the gastrointestinal tract of a patient in order to initiate an intestinal braking effect which would promote sensations of satiety and stimulate excess weight loss for the patient.

The present invention generally provides for a method of treating metabolic disorder by severing a bile duct from fluid communication with an intestine at a first target site adjacent the Oddi sphincter, thereby creating a severed bile duct. The method further involves re-establishing fluid communication of the severed bile duct with the intestine by attaching a distal end of the severed bile duct to a second target site along the intestine, wherein said second target site is distal to the first target site.
摘要:
A surgical stapler includes a head in which a plurality of staples are stored. The head includes a facing surface. The stapler also includes an anvil having an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including a facing surface opposed to the facing surface of the head for mating engagement therewith. The facing surface of the head is obliquely oriented relative to a longitudinal axis of the head creating an elliptical staple line when the head is brought into contact with anvil during actuation of the surgical stapler.
摘要:
An implantable system for stimulating the release of satiety hormone in a subject comprises a stimulus device (11) which is implantable in the subject and adapted to apply an electrical stimulus to a tissue of a gastrointestinal system of said subject, and a detection device which is implantable in the subject and adapted to continuously monitoring at least one of a mechanical characteristic and an electrical characteristic of the subject to detect an ingestion of food by said subject, wherein the detection device cooperates with the stimulus device (11) such that the stimulus device (11) applies said electrical stimulus in response to a detected ingestion of food.
摘要:
The present invention generally provides for a catheter for surgically treating a patient. The catheter has an inlet catheter having a proximal end and an open distal end, and first and second branch sections having proximal ends attached to the open distal end of the inlet lumen. The first and second branch sections and distal ends terminating at an open proximal end of an outlet lumen. The first passageway lumen has a device for deactivating at least a portion of the digestive enzymes in an amount of bile.

The present invention generally provides for a method for diverting a portion of the bilopancreatic secretions of a patient to the circulatory system. The method involves placing a proximal end catheter adjacent the sphincter of oddi and diverting bilopancreatic secretions into the catheter. The method further involves placing a distal end of the catheter within the lumen of the circulatory system of a patient.
摘要:
A positioning device for deploying at least one locking portion (20) of an anastomotic device (10) for drawing together a first tissue portion (12) and a second tissue portion (14) to be connected by means of anastomosis is suitable for sliding along a guide means comprising at least one guide wire (A, B) and comprises an elongated structure (50). A head (52) of the positioning device is suitable to be interference-inserted on a distal end of the elongated structure (50). The head (52) comprises elastic tabs (54) extending from a proximal end of the head and at least one channel (56) suitable for receiving a guide wire. The head (52) comprises a distal end defining a thrust surface (58) for a locking portion (20) of the anastomotic device (10).
摘要:
An instrumentation for carrying out a gastrointestinal bypass comprises means for bringing close together a first tissue portion (12) of the intestine and second tissue portion (14) of the stomach by realising a first intestine loop (A), means for creating a gastroenteroanastomosis (16) between the two close tissue portions, for example a linear stapler, maintaining or restoring the continuity of the intestinal duct after the realisation of the gastroenteroanastomosis, means for bringing close together an additional first tissue portion (18) of the intestine, arranged distally with respect to the gastroenteroanastomosis (16) with reference to the natural flow of the food along the intestinal duct, and an additional second tissue portion (20) of the intestine arranged proximally with respect to the gastroenteroanastomosis (16) with reference to the natural flow of the food along the intestinal duct, realising a second loop (B) of the intestine, wherein said additional second tissue portion (20) of the intestine arranged proximally with respect to the gastroenteroanastomosis (16) is brought close to the gastroenteroanastomosis (16), means for creating an enteroenteroanastomosis (22) between the two close tissue portions of the intestine, maintaining or restoring the continuity of the intestinal duct after the realisation of the enteroenteroanastomosis, and means for sectioning the intestine between the gastroenteroanastomosis (16) and the enteroenteroanastomosis (22).
