An optical spectroscopic injection needle assembly. According to one embodiment, the assembly may include an injection needle, a light source, a spectrometer, a computer and an indicator. The injection needle, in turn, may include a hollow outer needle, a hollow inner needle, a pair of optical fibers, an inner catheter, an outer catheter, an inner hub and an outer hub. The proximal end of the outer needle may be fixedly mounted within the distal end of the inner catheter. The distal end of the inner hub may be fixedly mounted on the proximal end of the inner catheter, the proximal end of the inner hub being suited for connection to a syringe. The inner needle, as well as the distal ends of the optical fibers, may be positioned within the outer needle and may be held in place by an optical bonding material. The proximal ends of the optical fibers may extend from a side arm of the inner hub, one fiber may be coupled to the light source, the other fiber may be coupled to the spectrometer. The inner catheter and the outer needle may be slidably mounted within the outer catheter to permit the outer needle to be selectively extended or retracted from the distal end of the outer catheter. The outer hub may be fixedly mounted on the proximal end of the outer catheter. In use, as the outer needle may be inserted into a tissue, the tissue may be illuminated and the reflected light may be detected and compared to standards for various tissue types. The results of the comparison may then be indicated.

Optical spectroscopic injection needle

Embodiments of the invention include a medical instrument with a sealing device. In embodiments, the medical instrument is endoscopic device having a seal between an elongate shaft member and/or on a portion of a handle to, for example, prevent flow communication between a lumen of the elongate member and the external environment.

Instrument with sealing device and methods of advancing fluid therethrough

An apparatus for performing endoluminal anastomosis of an organ comprises an operative head including an endoscope receiving lumen for slidably receiving a flexible endoscope therein, the operative head including an annular tissue receiving space extending around a circumference of a distal end thereof and a stapling mechanism for firing staples around an entire circumference of the tissue receiving space and a tissue gripping mechanism for drawing into the tissue receiving space a portion of tissue extending around an entire circumference of the organ.

Circumferential full thickness resectioning device

Embodiments of the invention include a medical instrument with a sealing device. In embodiments, the medical instrument is an endoscopic device having a seal between an elongate shaft member and/or on a portion of a handle to, for example, prevent flow communication between a lumen of the elongate member and the external environment.

Embodiments of the invention relate to a medical device having a proximal portion that can selectively receive other portions of the device. More specifically, embodiments of the invention relate to an endoscopic instrument with a handle portion configured to accommodate an elongate, flexible member and an end effector assembly of the endoscopic instrument for protection, coiling, looping, containment, packaging and for disposal. The device may have a variety of configurations.

Medical device and related methods of packaging

Embodiments of the invention include a cap for a medical device. The cap includes a body defining a cavity configured to accommodate at least a portion of an end effector assembly of the medical device, and a tissue removal portion attached to the body and configured to remove a tissue sample disposed within the end effector assembly when the cavity is not accommodating the end effector assembly. Embodiments of the invention also may include a medical kit including a medical device and a cap and a method of performing a medical procedure with the cap.

End effector assembly cap and tissue removal device and related methods

Embodiments of the invention relate to a medical device with a visual indicator that changes color when exposed to a particular environment and/or chemical. The visual indicator may be printed or otherwise affixed on a portion of a medical device, for example the handle, and initially have the same color as that portion. When exposed to a particular environment and/or chemical, the visual indicator changes color so that it has a different color than that portion of the medical device.
