A sampling device (9) for the use with an endoscope (1) having a suction channel and a suction connector (4) in communication with said suction channel. The sampling device (9) is adapted for connection to the suction connector (4) and said sampling device (9) is adapted for connection to a vacuum source. The sampling device (9) is adapted for forming a rigid connection with said endoscope (1) when connected to the suction connector thereof (4).

A handle for a medical device includes a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.

A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

A biopsy system for harvesting larger volumes of tissue as compared to standard core biopsy needles. The system has a needle with a lumen, an aperture disposed at the distal end of the needle and connected to the lumen, and a cutting mechanism adapted to cut tissue. When the needle is rotated after it is inserted into a target tissue, the cutting mechanism cuts from the tissue and directs the cut tissue portions into the lumen. Multi-bioimpedance measurements are used to guide a needle and direct the application of electricity for cauterizing tissue.

Disclosed embodiments provide a biopsy tool and methodologies for obtain biopsies and/or a tool and methodology that may be used to add material to a subject's tissue.

An improved flexible endoscopic instrument to precisely and efficiently obtains samples of flat polyps and multiple polyps from a patient by debriding one or more polyps and retrieving the debrided polyps without having to alternate between using a separate cutting tool and a separate sample retrieving tool and may be used with an endoscope. In one aspect, the cutting tool is coupled to a flexible torque coil or torque rope that is configured to transfer rotational energy from a powered actuator through the length of the endoscope onto the cutting tool.

A perineal prostate biopsy apparatus comprising a cannula for reaching a prostate gland of an adult human male through his perineum; and a coaxial needle comprising a hollow needle shaft having an open piercing tip at its distal end and being arranged to lie within the cannula so that the piercing tip protrudes from a distal end of the cannula; and, a stylet adapted to lie within the hollow needle shaft so that a distal tip of the stylet closes the piercing tip of the needle.

The present disclosure is directed to devices, systems, and methods for sensing and discerning whether a distal portion of a fat grafting cannula or probe is disposed in fat tissue or muscle tissue during fat grafting procedures. In one aspect of the present disclosure, a fat grafting cannula or probe is provided including first and second electrodes. Each electrode is coupled to a circuit, e.g., disposed in an electrosurgical generator. During a fat grafting procedure, the electrodes contact patient tissue. Based on signals received from each electrode, the circuit is configured to determine whether a distal portion of the fat grafting cannula is disposed in a fat tissue or muscle tissue. If the circuit determines that the fat grafting cannula is disposed in muscle tissue, the surgeon operating the fat grafting cannula is alerted to ensure that processed fat is not injected into the muscle tissue of the patient.

A biopsy system includes a biopsy probe configured to sever tissue to acquire a tissue sample. The biopsy probe has biopsy needle portion having a proximal end, a distal end, and a lumen. A vacuum source is coupled to the lumen. The vacuum source is configured to generate a vacuum to transport the tissue sample through the lumen and expel the tissue sample from the lumen at the proximal end of the biopsy needle portion. An arrangement of compression plates is configured to receive the tissue sample from the proximal end of the biopsy probe and is operable to compress the tissue sample. The arrangement of compression plates has a plurality of impedance measurement electrodes. An impedance measurement circuit is connected to the plurality of impedance measurement electrodes.

A combined system for diagnostic and therapeutic procedures includes a needle extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough, the distal end including a sharp grind for cutting a tissue sample to be collected in the lumen of the needle and a protective sheath sized and shaped to be inserted through the lumen of the needle such that a distal end of the protective sheath extends distally past the distal end of the needle, the protective sheath extending longitudinally from a proximal end to the distal end and including a lumen extending therethrough.
