Abstract: The invention consists of a tube syringe holding device for blood collection and for producing vacuum into the tube which target is to enable the collection of blood, that can be manufactured in a light material where two bodies, one of them cylindrical and the other semi-cylindrical, both hollow and of the same length, form one structure. Its bottom ends are opened. The top end of the cylindrical body is continued by a conduit with a male luer adapter, and the top end of the semi-cylindrical one is continued by two conduits with threads.

Abstract: A urinary catheter assembly comprises at least one urinary catheter (1) and a flexible tubular catheter package comprising a hose member (4) narrowly surrounding the catheter (1). A proximal end of the catheter is connected with a connector member (3) and the package comprises a tubular compartment (10) connected with the hose member (4) for accommodation of the connector member (3). The compartment (10) is closed in a first end by a detachable cover member (11) and is detachably connected with the hose member (4). The compartment (10) is further formed with walls (14) of a thin flexible material, so that by removal of the catheter (1) and the compartment (10) from the hose member (4) the compartment (10) may be arranged on the catheter shaft for used as an applicator for safely guided introduction of the catheter into the urethra (15).

Abstract: The invention provides methods, devices and systems for collecting breast ductal fluid comprising cellular material and other useful markers for analysis. The methods typically comprise access of at least one breast duct and collecting materials from that duct separate from all other ducts in the breast. The devices comprise ductal access devices that provide the opportunity to collect fluid from a single duct separate from all the other ducts in the breast. The systems employ the methods and devices that used together provide systems for analysis of a breast condition in a patient specific to accessed breast ducts. The methods, devices and systems are particularly useful for indentification of breast precancer or cancer in patient.

Abstract: A guide wire brake for use in an ablation assembly includes a clamp positioned in and between recesses provided in an air-actuated piston and a retainer. The clamp is provided with a first member and a second member coupled together on opposite sides of a spring member. An outer surface of the clamp is tapered to matingly engage the tapered inner surface of the first and second recesses. In operation, the piston is in fluid communication with a source of air. As air contacts an inner surface of the piston, the piston moves toward the retainer, thereby pushing the first and second recesses together along the tapered outer surface of the clamp. This action causes the first and second members to overcome the spring force of the spring member, and clamp together against a guide wire extending therethrough, thereby preventing longitudinal and rotational motion of the guide wire.

Abstract: A device having a protection cap defining a concavity, and a thin sharp-ended tubular stem joined to the cap and projecting into the concavity; the tubular stem being connected to elements for penetration into the human body or into body liquid containers; the device being also suitable for use in combination with sample tubes to be inserted into the concavity in the cap and having their interior chamber under vacuum and closed by a yieldable elastomeric plug able to seal an aperture produced by the tubular stem; the tubular stem being joined at one end to the interior concavity of the cap and constructed of a synthetic resinous material in one piece with the cap.

Abstract: A simple automatic opening and closing type of urination apparatus (10) comprises a flexible tube (110), a plunger (120), a bearing table (130), an elastic member (140), an electromagnetic solenoid (150), and an actuator (160). The flexible tube (110) has an inlet port (111) and an outlet port (112). The plunger (120) has a pushing portion (121) at one end and a contact portion (122) at the other end. The bearing table (130) is disposed below the pushing portion (121) of the plunger (120) for supporting the flexible tube (110). The elastic member (140) normally biases the pushing portion (121) of the plunger (120) onto the flexible tube (110) on the bearing table (130) to squeeze the flexible tube (110) between the pushing portion (121) and the bearing table (130). The electromagnetic solenoid (150) selectively attracts and repulses the contact portion (122) of the plunger (120). The actuator (160) selectively couples the electromagnetic solenoid (150) to a power source (170).

Abstract: A multichannel, multipurpose sample collection and drug delivery system for laboratory animals includes several sampling and/or infusion devices mounted on a powered turntable above the cage but out of the animal's sight. Probes are constructed using a unique four-channel design: this permits (a) the periodic infusion of drugs without the possibility of artifacts due to pressure shocks and (b) the addition of preservatives to the sample at the site of its collection. A simplified sample collection device stores samples in a coil of PTFE tubing, and a constant-pressure perfusion system serves microdialysis probes.

Abstract: A biopsy instrument including a tissue penetrating device including an elongate holder and a cutting member arranged at an end thereof for penetrating tissue and a specimen retaining and retrieval device detachably connected to the holder for receiving and retaining a specimen of tissue cut by the cutting member. The specimen retaining and retrieval device preferably has a handle having a contoured, outer surface substantially corresponding to the shape of a thumb and which is roughened. Also, preferably the tissue penetrating device includes a hand grip section arranged at an end of the holder opposite to the end at which the cutting member is arranged and a middle section arranged between the hand grip section and the cutting member, the middle section being substantially cylindrical and having friction grip enhancing means, i.e., grooves arranged on an outer peripheral surface in a direction substantially perpendicular to the longitudinal direction of the tissue penetrating device.

Abstract: A single use device for analyzing a body fluid in an elongate body cavity including a pipe element with a neck and a bottom wall and a liquid transfer assembly partially located within the element and extending through a sampling region outside the neck to an axial collection point located within said element in the region of the bottom wall.
