The vascular graft comprises a tubular body having a proximal end and a distal end, the proximal end being configured to be attached to a vessel in a patient's body. The at least one valve is configured to be attached to the distal end of the graft's tubular body and comprises a housing including a flexible membrane that allows a medical device to be inserted through the membrane into said vascular graft. The valve further comprises an introducer sheath configured to be inserted into the distal end of the graft's tubular body. The at least one clamp is configured to be disposed around the graft's tubular body and has a first configuration that allows insertion of the valve's introducer sheath into the distal end of the graft's tubular body and a second configuration that allows clamping of the graft against the valve's introducer sheath, when inserted in the graft's tubular body.

A system for providing vascular access in a patient's body may comprise at least one hemostatic valve (610) and at least one clamp (210) to be used with a vascular graft (110). The vascular graft (110) comprises a tubular body having a proximal end (110A) and a distal end (110B), the proximal end (110A) being configured to be attached to a vessel in a patient's body. The at least one valve (610) is configured to be attached to the distal end (110B) of the graft's tubular body and comprises a housing (616) including a flexible membrane (611) that allows a medical device (810) to be inserted through the membrane (611) into said vascular graft (110). The valve (610) further comprises an introducer sheath (615) configured to be inserted into the distal end (110B) of the graft's tubular body. The at least one clamp (210) is configured to be disposed around the graft's tubular body and has a first configuration that allows insertion of the valve's introducer sheath (615) into the distal end (110B) of the graft's tubular body and a second configuration that allows clamping of the graft (110) against the valve's introducer sheath (615), when inserted in the graft's tubular body.

A hemostasis valve assembly includes a hollow body delimiting an inner passage for inserting a medical material, the inner passage extending between a proximal opening and a distal opening of the hollow body, a distal seal arranged at the distal opening, a proximal seal arranged at the proximal opening, a spacer element arranged between the distal seal and the proximal seal, and an end cap. The distal seal is an elastic valve that is sealed when idle. The end cap has a fixing element engaging a support element of the hollow body to fix a stacked assembly including the distal seal, the spacer element, and the proximal seal inside the hollow body.

A catheter hub assembly. The catheter hub assembly includes a catheter hub body, a septum and a septum retainer, the catheter hub body having a distal end, a proximal and an internal wall defining an internal fluid passageway therebetween, the internal wall defining a transitional step within the internal fluid passageway, the septum positioned within the internal fluid passageway such that a distal end of the septum abuts up against the transitional step, the septum retainer at least partially receivable within the internal fluid passageway and having an outer wall shaped and sized to interlock with the inner wall of the catheter hub body, the outer wall including one or more lateral ribs configured to inhibit rotation of the septum retainer relative to the catheter hub body.

Biopsy caps and seals, and methods for making and using the same may be provided in conjunction with an endoscope assembly. A seal may include a main body including a circumferential outer wall surrounding a central lumen. The seal may include at least one support wall extending radially from the outer wall towards a center of the lumen, and at least one helical flap extending from the support wall helically downward along an inner surface of the outer wall, where the at least one helical flap defines an opening at the center of the lumen. The seal may alternatively include a plurality of projections extending radially inward from the outer wall towards a center of the lumen, where the plurality of projections are arranged in a series of circumferentially and angularly offset layers.

The present disclosure relates generally to the field of medical instruments. In particular, the present disclosure relates to a biopsy cap and endoscope biopsy cap housing with improved stability and stress distribution to securely and removably attach to an endoscope biopsy port. In one example, a biopsy cap housing may include a first center-split half comprising a first half of an upper and lower chamber and first pivot member, and a second center-split half comprising a second half of an upper and lower chamber, and second pivot member, wherein mating surfaces of the first and second center-split halves may be configured to interlock to define the upper and lower chambers.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

A medical device may include a seal portion having a first seal wall extending to a first lip and a second seal wall extending distally to a second lip that contacts the first lip, the first lip and second lip defining a slit, and a rim portion extending around the seal portion, the rim portion being curved or bent in a proximal direction.

Needle assemblies and related methods are disclosed having a needle hub with a needle, a catheter tube with a catheter hub and having the needle extending through the catheter tube; and a valve positioned in an interior cavity of the catheter hub, the valve having a first section with a first chord, a second chord, and a plurality of slits defining a plurality of flaps, a second section attached to the first section, and a third section attached to the first section; an inside edge formed on the second section and pressed against the first section; an inside edge formed on the third section and pressed against the first section; and wherein a first flow path is provided adjacent the first chord and a second flow path is provided adjacent the second chord.

Aspects herein relate to a low-friction septum for providing a leak-resistant seal for use in a vascular access device. In an embodiment, a device for vascular access hemostasis is included having an enclosure defining a cavity and configured to at least partially receive a medical device. The device can include a first seal portion and a second seal portion, the cavity disposed between the first seal portion and the second seal portion. The device can include a barrel in structural communication with the second seal portion, the second seal portion including a septum seal. The second seal portion can define two or more discrete portions, each separated by one or more split lines. The discrete portions can include a mating surface to interface with mating surfaces of other discrete portions. The mating surface can include a surface topology including raised portions and depressions. Other embodiments are also included herein.
