A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.

Fecal management methods and apparatuses (e.g., devices, systems, etc.) are described herein. The fecal management apparatuses may apply one or more fecal removal cycles of suction and irrigation (and in some examples air) to actively remove fecal material. The apparatus may control the timing of delivery of the fecal removal cycles as well as the parameters of the applied suction, irrigation and/or air within and between fecal removal cycles. The invention additionally provides methods, and computer program products for controlling an apparatus or system that is configured for removal of fecal material from a patient's rectum.

System and methods for stimulating cartilage formation at a first tissue site through a second tissue site is presented. The system includes a fluid source for supplying a therapeutic solution, a reduced pressure source for supplying reduced pressure, a fluid delivery manifold for deploying adjacent the first tissue site, and a vacuum manifold for deploying within the second tissue site. The fluid delivery manifold extends between a proximal end fluidly coupled to the fluid supply and a distal end having at least one aperture for delivering the therapeutic solution to the defect adjacent the articulating surface of the first tissue site. The vacuum manifold extends between a proximal end fluidly coupled to the reduced pressure source and a distal end having at least one aperture for delivering the reduced pressure to the first tissue site adjacent the opposing surface of the first tissue site.

A surgical system comprises a pressurized irrigation fluid source; an irrigation line fluidly coupled to the pressurized irrigation fluid source; a hand piece fluidly coupled to the irrigation line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on an estimated flow value modified by a compensation factor.

Methods of colon cleansing and/or inspection are described which safely maintain a colon in an uncollapsed state. Balanced replacement of a volume of fluid, gas and/or solids evacuated during cleansing of the colon is described. Replacement volume comprises, for example, cleansing fluid, jetting gas, and/or inflation gas. In some embodiments, balancing of evacuated and replacement volume is achieved under automatic control, based on monitored volume of material exchange, and/or measurement of resulting pressures.

A fluid management system may include an inflow pump providing a fluid inflow to a medical device, at least one pressure sensor, and a controller configured to receive pressure signals from the at least one pressure sensor, the pressure signals corresponding to a system pressure within the fluid management system. The controller may be configured to detect which one of a plurality of medical devices is fluidly connected to the inflow pump based on the pressure signals from the at least one pressure sensor and an rpm of the inflow pump.

A biopsy device includes a disposable elongated probe component having a coaxial arrangement of an elongated tubular section and an elongated tissue cutting member, and having a coaxial arrangement of a first driven gear, a second driven gear, and a third driven gear. The first driven gear is configured to rotate the elongated tubular section. The second driven gear is configured to rotate to longitudinally move the elongated tissue cutting member. The third driven gear is configured to rotate or oscillate the elongated tissue cutting member. A driver component has a coaxial arrangement of a first drive gear, a second drive gear, and a third drive gear. The first drive gear is drivably engaged with the first driven gear. The second drive gear is drivably engaged with the second driven gear. The third drive gear is drivably engaged with the third driven gear.

Inline pumps with rear attachable syringes include a pump and a syringe with each designed so that the pump syringe system may be easily coupled and decoupled in the field. An end mount block on the pump has a slot shaped to accept a similarly shaped plunger button and plunger rod on the syringe. A user aligns the plunger button of the syringe next to the slot on the mount block of the pump, and slides the plunger button and rod into the inner cavity of the pump. Both the pump and the syringe have threaded couplers which securely couple the pump to the syringe by rotating the couplers with respect to each other.

The utility model discloses a urinary catheter for women and peristaltic pump, which comprises a body tube with an inner surface and an outer surface, and further comprises an external urethral orifice fixing part which can at least sleeve the catheter tip end inside when applied, a flexible urethral guide part, a urinary catheter driving part sleeved with the cylindrical body of the external urethral orifice fixing part, a hydrophobic part for leakage stop at the urinary outlet of the urinary catheter, a thin segment, a pump tube, a tube bed and other special structures for dilating the narrowed part of the urethra, which not only eliminate the defect of the traditional “non-guided suspended placement” in a safe mode of “US-guided adjacent placement” and completely avoid contamination of the urinary catheter by the periurethral tissue, but also avoid the injury of urethral intima caused by urethral stricture in the placement procedure to the greatest extent; avoid contamination of the urinary catheter outlet by urine outflow; effectively clear the blockage of urine inlet due to blood clots and tissue masses in bladder during indwelling, and can also minimize the residual urine volume when used in conjunction with a special peristaltic pump.

A method for capturing dislodged vegetative growth during a surgical procedure is provided. The method includes maneuvering, into a circulatory system, a first cannula having a distal end and an opposing proximal end, such that the first cannula is positioned to capture the vegetative growth en bloc. A second cannula is positioned in fluid communication with the first cannula, such that a distal end of the second cannula is situated in spaced relation to the distal end of the first cannula. A suction force is provided through the distal end of the first cannula so as to capture the vegetative growth. Fluid removed by the suction force is reinfused through the distal end of the second cannula. Subsequent to becoming dislodged, the vegetative growth is captured by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.
