摘要:
In one embodiment, an endoscope includes an elongate member having a proximal end portion and a distal end portion. The distal end portion is configured to be inserted into a body lumen. An electrical component is disposed within the distal end portion of the elongate member and configured to produce a signal. An elongate conductive mechanical component has a proximal end portion and a distal and portion. The distal end portion of the elongate conductive mechanical component is electrically coupled to the electrical component and configured to conduct the signal or electrical power from/to the electrical component to/from the proximal end portion of the elongate conductive mechanical component.
摘要:
Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. The catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.
摘要:
An apparatus includes an optical fiber extending from a proximal end to a distal end. The optical fiber may include a cladding layer circumferentially disposed about a core layer and a substantially spherically shaped portion at the distal end. The apparatus may also include a first coating circumferentially disposed on a first length of the cladding layer, and a second coating circumferentially disposed on a second length of the cladding layer. The second length may extend distally from a region proximate the distal end of the first coating.

Embodiments of the invention include a device to provide working access to a surgical site in a patient. The device may include a port component including an elongate member configured to pass through an opening in the patient. The elongate member may include a bore extending between a distal end and a proximal end of the elongate member. The port component may also include an expandable member disposed on the elongate member that may perform dissection and may form a seal to maintain insufflation pressure in a working space. The device may also include an insert component configured to be removably received inside the bore in the elongate member of the port component. The insert component may include at least one lumen that may removably receive at least one working instrument.
摘要:
The present invention provides (8.beta.)-N-substituted cyclo or bicycloalkyl-6-(substituted)-ergoline-8-carboxamides useful for occupying 5HT.sub.2 or 5HT.sub.1c receptors in mammals. The invention also provides methods for treating a variety of disorders and conditions related to or affecting these receptors as well as pharmaceutical formulations of the compounds of the invention.
摘要:
This invention provides a method of selectively antagonizing the 5-HT.sub.1A receptor in mammals by administering aryloxypropanolamines. Aryloxypropanolamines are also claimed.
摘要:
This invention provides bicyclic carboxylic esters and amides, their pharmaceutical formulations, and a method for their use in treating migraine, emesis, gastrointestinal disorders, schizophrenia, or anxiety in mammals.
摘要:
This invention provides N-alkyl-3-phenyl-3-(2-substituted phenoxy)propylamines which are useful to treat neurological disorders associated with norepinephrine imbalance.
摘要:
The present invention provides 3-(4-substitutedphenoxy)-3-phenyl propanamines capable of inhibiting the uptake of serotonin. These compounds are useful for treating many pharmacological disorders, including depression and obesity. These compounds can also be used to reduce the desire to smoke and consume alcohol.
