Methods and design for a Slotted T-shaped PD Catheter are disclosed. The present invention includes a unique port design for peritoneal dialysis catheters that allows high outflow and inflow rates, with a minimum fluid velocity through the fluid entry ports. Features of this device include T-shaped catheter with subcutaneous tubing joining to an intraperitoneal portion that is essentially at right angles to the intraperitoneal tubing and slit shaped flow ports as opposed to round shaped flow ports.

To keep a clean area separated from an unclean area, a drape unit for separating the manipulator that has a treatment section at a distal end of an elongated section and that has at a proximal end a proximal-end drive unit from the base including, on a substantially horizontal top surface, a drive source to which the proximal-end drive unit is detachably connected, the drape unit includes: a drape main body that has an opening from which the drive source is exposed; and an adaptor that is interposed between the drive source and the proximal-end drive unit, that is disposed with a gap vertically above the opening, and that covers the entire opening, the adaptor includes a force transmission unit for transmitting the driving force from the drive source to the proximal-end drive unit.

Medical devices and methods for making and using medical devices are disclosed. An example method for manufacturing a medical device may include cutting a tubular body into a plurality of ring members. The plurality of ring members may include a first ring member and a second ring member. A connecting member may extend between the first ring member and the second ring member. The method may also include disposing a polymeric member along the plurality of ring members to define a tubular member and articulating the tubular member to break the connecting member.

A medical overtube includes a multi-lumen tube provided with a plurality of lumens through which medical devices are to be passed; a braided tube which covers an outer side of the multi-lumen tube and is made of braided fibers; and an outer tube that covers an outer side of the braided tube, wherein a through hole is formed in the multi-lumen tube or the outer tube, the through hole is configured to connect a space, which is covered by the outer tube and the multi-lumen tube and in which the braided tube is disposed, to an exterior.

The disclosed technology includes an expandable basket assembly for a medical probe, which may include a single unitary structure comprising a plurality of spines converging at a central spine intersection, the central spine intersection being positioned on a longitudinal axis of the expandable basket assembly at a distal end thereof. The plurality of spines may include a first layer and a second layer attached to the first layer and including a central cutout about the central spine intersection that exposes the first layer at the central spine intersection. The plurality of spine may include a central electrode attached to the first layer at the central spine intersection via a central aperture in the first layer at the central spine intersection. The second layer may be configured to articulate independently of the first layer at the central spine intersection.

A method for manufacturing a catheter (102) including a rapid exchange port (157). The method can include the steps of creating a port (258) in a catheter shaft (210), inserting a port tube (360) into the port (358), skiving the port tube (360) so that it is flush with the catheter shaft (310), inserting a guidewire lumen (718) into the port tube (760), coupling the guidewire lumen (718) to the port tube (760), and skiving the guidewire lumen (718) so that it is flush with the catheter shaft. The method can also include the steps of inserting a port mandrel (462) into the port tube (460), inserting a catheter mandrel (464) into the catheter shaft (410), positioning a heat shrink (465) over a portion of the catheter shaft (410), applying heat to the heat shrink (465), removing the port mandrel (462) from the port tube (460), removing the catheter mandrel from (464) the catheter shaft (410), and sealing a gap between the guidewire lumen (718) and the port tube (760).

The present application relates to a method for producing a catheter tube. The method including sucking gas from a second end 43 of a tubular body 40 while introducing pressurized gas into a lumen 41 of the tubular body 40 from a first end 42 of the tubular body 40, so that an internal pressure is applied to the lumen 41 of the tubular body 40 by introducing the pressurized gas, and the tubular body 40 is delivered in a direction from the first end 42 to the second end 43 by sucking the gas from the second end 43 of the tubular body 40.

A catheter, which can be used in infusion therapy, includes a catheter tube having a main lumen and at least one secondary lumen. The main lumen and the at least one secondary lumen are each elongate between a proximal tube end and a distal tube end. The at least one secondary lumen has a lateral opening arranged between the proximal tube end and the distal tube end in an axial direction of the catheter tube. The lateral opening extends through a tube casing of the catheter tube in a radial direction of the catheter tube. A seal is introduced into the at least one secondary lumen distally behind the lateral opening and at least partially seals the secondary lumen. The seal is formed from a sealing compound cured in the at least one secondary lumen or a thermoplastic elastomer material expanded within the at least one secondary lumen.

A neurosurgical apparatus for convection enhanced delivery of an infusate to the brain parenchyma, the apparatus comprising: a guide tube for insertion into the brain and having a proximal end, a distal end and a through-bore for passage of a cannula; wherein at least an outer layer (24) of the guide tube is of a hydrophobic material that is resiliently deformable and porous to allow passage of air. Also provided is a kit for convection enhanced delivery of an infusate to the brain parenchyma and a surgical method for convection enhanced delivery of an infusate to the brain parenchyma.
